Analysis of e-Portfolio-Themes and Reflections

Through an analysis of my ongoing e-folio there are a few different themes that I notice and that I can reflect upon as I continue to integrate technology into my math and inquiry teaching.  As an elementary educator I do not currently teach the science strand as we have planning teachers that do this, but I am teaching math and since I teach with an inquiry based approach there are many ways that science related activities are incorporated in my teaching throughout the day in a cross curricular approach.

The idea of a constructivist approach not only fosters knowledge generation but allows the students to take charge of their learning and allows students to find a pathway to their learning that is more meaningful. In this way, constructivist activities allow for student led learning, with teacher as facilitator. As Kozma (2003) notes, teachers are not the disseminators of information but rather act as the “guide on the side”, providing planning, structure and ongoing check-ins and assessment for learning.” With this type of learning, the educator must have proficiency using technology tools and platforms in different ways, so ongoing collaboration between educators as well as ongoing training would be an important piece of this puzzle. As Schulman (1986) noted in his research, teacher training and the type of training provided needs to be revised to reflect both content and pedagogical knowledge so that educators are prepared to effectively integrate technology into their math and science classrooms.

This link between educator proficiency, technology tools and supports is a recurring theme that is important when considering technology in the math and science classroom. Students require scaffolding when using many of these tools or designs but we must also remember that the educators also require training, scaffolding and to use reflective practice to ensure the platform they have chosen suits the needs of the students and that the platform used is specifically chosen for a purpose, and not just to “add” technology to the classroom. In this setting, students would be encouraged to work collaboratively and to reach findings and to use technology to its full capabilities including analysis, problem solving, designing and implementing. Questions educators must ask are: Do I require more training so that I can integrate these technologies into my math and science program? How can I provide proper scaffolding/pedagogical practices to support the students as they use the technology? How will I know that the technology has added to the students’ knowledge generation?

Schulman (1986) speaks to the distinction between knowledge and pedagogy. Three important questions can be asked as we as educators reflect on our teaching in math and science:

  • How are decisions about teaching made?
  • How do I represent content?
  • How do I question students and how do I deal with problems of misunderstanding?

These ideas fit well when considering the different learning environments that technology can provide to engage students in robust learning activities and knowledge construction. The learning environments explored in this course including, Anchored Instruction/Jasper, SKI/WISE, LfU/MyWorld and T-Gem/Chemland all provide opportunities for students to construct their own knowledge through the use of technology. As an educator, I would choose the platform depending on the needs of my students, the curricular goals and the availability of the technology.  I would also take into account the time to complete these in a meaningful way. Analysing these learning environments provided me with more insight into the benefits and possible drawbacks of each platform.  Some of the proposed benefits of using these learning environments include the ability for students to use complex problem solving, communication and collaboration are fostered, scaffolding is integrated into most of the platforms, many are customizable and adaptive and reflections are built in. The educator acts as facilitator, gently guiding the students through the learning process. Students have the ability to explore relationships and use reasoning skills within these learning platforms and some have integrated data analysis and record keeping abilities which help students explore concepts more fully.

As an elementary educator I was drawn to using Anchored Instruction/Jasper with younger students. I think the videos could be tailored to elementary science/math curriculum and that the technology-based learning approach which stresses the importance of placing learning within a meaningful, problem-solving context (video stories) would be meaningful for students. In addition, the T-GEM/Chemland technology supported learning where students generate ideas, evaluate ideas and modify based on discrepancies discovered would also be beneficial for younger students. These two learning environments would be accessible, could be tailored to the age/understandings of the students and would provide a technology driven environment that could be explored successfully with the teacher as the guide on the side.

I do think that each technology supported environment provides its own “positives” depending on the style of the educator, the needs of the students, the age of the students and access to technology. In addition, timelines must be considered and I believe each of these requires more time to allow students to find relationships, deepen their understandings, communicate with each other and reflect on their learning’s, and even more time if they are to apply these understandings in real-world contexts. These considerations can be stumbling blocks especially in elementary settings where we are required to teach many subjects and devote enough time to teaching them well. Cross curricular approaches seem to be the best solution to this, but they require more planning and the assessment may be less linear. That being said it cannot be understated that these environments provide deep, rich understandings.  In addition, I would like to add that supporting and educating teachers to use these valuable resources should be a goal so that science/math education can continue to support deep, engaging and meaningful learning for students.

Through my research I also examined how these technology platforms could assist students with learning disabilities in the mathematics classroom. Of particular interest was that detailed curriculum design and teaching practices result in enhanced mathematics. The researchers focussed on the essential attributes of effective practice. They went further and defined “explicit instruction”, which in previous research has shown positive effects in terms of increased understanding of mathematical skills for students with learning disabilities. The researchers broke it down into three components: (a) The teacher demonstrated a step-by-step plan (strategy) for solving the problem, (b) this step-by-step plan needed to be specific for a set of problems (as opposed to a general problem-solving heuristic strategy), and (c) students were asked to use the same procedure/steps demonstrated by the teacher to solve the problem (Gersten, Chard, Jayanthi, Baker, Morphy & Flojo, 2009). The two instructional components that provided significant benefits were teaching students to use heuristics (a process or method) to solve problems and explicit instruction (Gersten et al., 2009).

So, reflecting on the Jasper series and other technology tools discussed, perhaps introducing complex problems that students have to work through may be of benefit to some students but not all. This is why we, as educators need to be selective when using these technologies in our math and science classrooms. From this research it appears that students with learning disabilities would not benefit from the Jasper adventures which are purposely created to reflect the complexity of real world problems (Cognition and Technology Group at Vanderbilt, 1992).  Before we use these technologies carte blanche in our classrooms we need to consider the diverse needs of our students first.

It appears that teachers and students also benefit if the teachers are given specific guidance on addressing instructional needs or curricula so that they can immediately provide relevant instructional material to their student. This is an important point to discuss as educators are often expected to know what to do in all situations with a variety of different styles of learners, with a variety of curriculum and with a variety of learning abilities.

Another theme throughout my e-portfolio and in science specifically, is that it has been found that students have many misunderstandings developed either through experiences, concepts or examples (Linn, M., Clark, D. & Slotta, J., 2003).  The use of technology in the science classroom can be one way to alleviate these misunderstandings.

For example, research notes that although light is an everyday phenomenon that we constantly observe, students often display learning difficulties and hold unscientific understanding on physics concepts of light wave (Srisawadi & Kroothkeaw, 2014). In addition, concepts of light such as its speed and wave length are removed from the range of perceptions of the human senses, and so optics instruction can be subject to interpretation, so there is a need for careful consideration in physics teaching process (Srisawadi & Kroothkeaw, 2014). Computer simulations can broach this divide. Computer simulations can enhance generating relationships and allow students and teachers the opportunity to view trends, variables and visual representation in more concrete ways which may lead to more accurate conceptual understandings (Khan, 2011).

Using T-GEM principles the educator can lead the students through generating ideas, evaluating these ideas and modifying them based on the discrepancies discovered. Online simulations, modelling or other visual representations can help to reach these aims.

In addition, research has shown that role play with elementary school students enables them to adopt different identities and act out their fictitious roles and allows students to have the opportunity to think differently and question their prior beliefs. (Lin, Chiu, Hsu & Wang, 2015). In one study, a computer-supported role-playing game was used which provided clear directions for the assigned roles and forced the students to consider different view of controversial issues. When students’ prior beliefs were inconsistent with their assigned roles, it led to conflict, which then had the possibility of inspiring new perspectives, and so enhancing their abilities to construct an argument ( Lin et.al, 2015).

When identifying misconceptions, educators should be aware that these can also be fostered through the use of certain technologies. For example, when considering virtual reality in the science or mathematics classroom, research shows that students may misinterpret or overlook important information in a simulation and teachers may be tempted to believe that simulations are automatically effective in communicating complex models to students (Stephens & Clement, 2015). Following this, in order to support knowledge generation teachers need to support students to promote reasoning and comprehension during use of simulations. As part of this, research has suggested that many teachers may need more guidance provided along with simulations to help them identify which features and relationships may be overlooked by students (Stephens & Clement, 2015). Virtual reality alone will not suffice and educators require information and guidance on how to support learners through the science knowledge generation process in networked communities.

WISE curriculum projects attempt to broach scientific misunderstandings through promoting knowledge integration through providing inquiry projects which are flexible, customizable and adaptive.  In this way WISE is a bottom up approach rather than a top down approach and is meeting the educational goal of delivering curriculum in a differentiated way, which is one of the goals of education.

Further to this, many WISE inquiry projects have been designed with detailed steps for the first inquiry investigation and then providing less detailed steps in subsequent projects. In this way students are able to move from supported learning to more independent pathways. This method is debated. When considering the Jasper Series, the belief that students can develop basic skills in the context of meaningful problem posing and problem-solving activities rather than isolated “targets” of instruction seems to refute this. That being said, the Jasper Series coincides with WISE with its emphasis on complex, problem solving, communication and reasoning and in connecting mathematics to the world outside the classroom. (Cognition and Technology and Technology Group at Vanderbilt, 1992).

In reflection, the technology tool used should be carefully chosen to meet the needs of the students and the aims of the educator. In addition, a look at the curriculum can also lead an educator to choose one learning environment over another. Do the students require a more step-by-step scaffolded approach or are they ready for problem-solving activities where the learning happens as they work through the problem? Perhaps the answer to this lies in the pedagogical approach of the educator. If we have prepared the students to work in both types of environment before introducing the technology they may be able to manage either environment. So a mix of scaffolded linear style teaching and learning and a problem-solving approach will provide the best opportunity for students to learn in a myriad of ways.

Student engagement is another theme I noted throughout my portfolio. For example in the (LfU) Learning for Use environment the learning task aims to promote discussion about the science concept explored and to promote communication. The LfU reasoning for this is to elicit curiosity and to have students confront limitations in their understandings (Edelson, 2001). It is noted in other literature that students are not likely to change their understandings in science until they notice contradictions to existing ones and that constructing relationships is a way to breach this divide (DeLaughter, Stein, Stein & Bain, 1998). LfU design creates demand for learning and eliciting curiosity. In the Create-a-World project the students are required to create a fictitious world, and this would be the impetus for learning about temperature and climate.

So, eliciting curiosity through identifying potential misconceptions and for activating existing knowledge can be achieved with technology. Technology can provide simulations which may be unavailable to direct observation (Edelson, 2001). Technology may also provide ways to articulate and demonstrate concepts using, for example, drawing programs. Eliciting curiosity may not happen with traditional style lecture or through textbooks which often tend to be outdated or misrepresent scientific concepts.

Role play can also be developed in the science classroom as a way for students to engage with their learning, learn to understand and share alternate perspectives, and foster communication, problem solving, decision making and critical thinking skills. For example In one  role play and case study to research environmental science students added to their science content knowledge through research or inquiry investigations about a local issue through examining environmental issues in their agricultural community (Deaton & Cook, 2012). The goal of this role play/case study could be enhanced through TELE. As part of the study students were required to research science content, and participate in role-playing which could be enhanced through well designed simulations or virtual reality.

In summation, it is the educator who is an integral part of creating the environment in which knowledge generation can occur in the math and science classroom. The educator must consider his/her own personal needs in terms of training or supports that may be required to effectively use technology in the classroom. The educator must also consider the needs of the students and how technology can be incorporated effectively and with purpose. The educator needs to know when to gently guide students through their learning and to identify and mitigate misunderstandings if and when they occur. The educator must consider how to keep the students actively engaged in their learning so that knowledge can be generated. The educator needs to understand how to use a variety of technology tools to help facilitate discussion, collaboration and reflection. The educator must work towards providing a differentiated environment when using technology, so that all students including those with learning disabilities benefit. In addition, the educator must critically examine the technology used to ensure it is not creating more misconceptions, and this is done through assessing on an ongoing basis throughout the process and making corrections as necessary.

How is Knowledge about Science Generated in Networked Communities- In consideration of Virtual Reality

When considering networked communities we must first look at how to establish this sort of community and what principles are important in a successful one. In constructivist models, problem solving is at the heart of learning, thinking, and development.  Learners solve problems and discover consequences by reflecting their experience and thus construct their own understanding.  That being said, research shows that knowledge construction is rarely done in isolation but rather by creating and forming a knowledge building community (Lamon, Laferriere & Breuleux, in press). In fact, the goal for learning communities is for a group of people with focused common issues or problems to discourse and work to find solutions to problems, complete tasks, or refine processes beyond the capabilities of any single person. (Lamon et al., in press). The building of a classroom community of learners must be paramount for this type of community to foster.

When considering science knowledge generation in this sphere, several things need to be considered. Research shows that students may misinterpret or overlook important information in a simulation and teachers may be tempted to believe that simulations are automatically effective in communicating complex models to students (Stephens & Clement, 2015). Following this, in order to support knowledge generation teachers need to support students to promote reasoning and comprehension during use of simulations. As part of this, research has suggested that many teachers may need more guidance provided along with simulations to help them identify which features and relationships may be overlooked by students (Stephens & Clement, 2015). Virtual reality alone will not suffice and educators require information and guidance on how to support learners through the science knowledge generation process in networked communities.

To expand on this, research has shown that new knowledge is created in a social process and in concrete situations, and this will occur if a community has reached the boundaries of its existing knowledge and are exposed to conflicting concepts (Johannes, 2011). Using virtual reality to meet the goals of knowledge generation in science is prescient in several ways. Learner object interaction in virtual reality provides the model of a cognitive operation that learners have to carry out mentally in order to create their own mental model of certain facts or of a topic of instruction. It may support knowledge building especially in such domains in which spatial information is essential for understanding. In addition, in networked communities personal and social presence is fostered within the community and is amplified if students are affected personally and see some connection between their own person and what happens in a virtual reality. This also increases collective cognitive responsibility of a group for succeeding together (Johannes, 2011). Educators can provide for rich knowledge generation in networked communities through providing virtual reality experiences that tap into connections or experiences that students feel are relevant to them.

The educator is an integral part of creating the sustainability of knowledge generation through virtual reality as the educator sets up the environment for knowledge generation to occur. The educator must consider the needs of the students, gently guide them back on the right path if they have strayed too far, and always keep in mind the dynamics of the networked community and how to facilitate discussion and reflection. In addition, the educator must critically examine the virtual reality to ensure it is not creating more misconceptions, and this is done through assessing on an ongoing basis throughout the process and making corrections as necessary. So, in my mind, knowledge generation in a networked community depends more on frontloading the experience, carefully monitoring the process of social interaction and knowledge generation and providing time for all of this plus time to reflect on the learning.  I look forward to your views about this.

Role Playing in Science and TELE- Benefits for Younger Children

Role playing may not be promoted in math and science due to the time it takes to front load these activities and also the fact that these subject areas have traditionally been taught through the dissemination of information and rote learning of concepts. Another reason role playing may not be promoted is due to the fact that evaluating students in role-playing is not as clear cut as traditional forms of assessment and in fact in addition to assessing students on the “performance” aspect of the exercise, students should also be accountable for their research, preparation, and collaboration with peers (Howes  & Cruz, 2009). The preparation for this type of learning falls directly on the educator and is much more work than traditional test style assessment.

With educational reforms, research is showing that deeper learning can occur when these subjects are taught in a more constructive or inquiry based way.  Research has shown that role playing along with a technology enhanced learning environment engages students in their learning. In addition, it can lead to more authentic learning and allow students to develop multiple perspectives ( Howes & Cruz, 2009). The benefits of role playing include promoting communication skills, building understandings, allowing for problem solving, decision making and critical thinking skills, all skills useful in STEM. Research has shown that role play with elementary school students enables them to adopt different identities and act out their fictitious roles and allows students to have the opportunity to think differently and question their prior beliefs. (Lin, Chiu, Hsu & Wang, 2015). In one study, a computer-supported role-playing game was used which provided clear directions for the assigned roles and forced the students to consider different view of controversial issues. When students’ prior beliefs were inconsistent with their assigned roles, it led to conflict, which then had the possibility of inspiring new perspectives, and so enhancing their abilities to construct an argument ( Lin et.al, 2015).

In another study, a role play activity “Prey Play” provided fifth grade students with opportunities to examine predator–prey interactions. Again, engagement was paramount and the role play allowed the students with opportunities to interact with materials and science content. Additionally the role play was purposely created with the local area in mind so that students found the learning relevant and also that it was familiar (Deaton, Dodd, Drennon & Nagle, 2012).This too applies to embodied learning. For example virtual reality seems to show the most benefit when the students can ground their learning in “real life” contexts and have a purpose for their learning.

When considering the younger child, the preparation and process of the role play activity may require more scaffolding as compared to older learners.  For example in the “Prey Play” activity,  educators discussed expectations for student behavior before heading outside for the role play. In addition, prompts and questions were asked throughout the series of role plays to ensure that the students were on the right track with their learning about predators and prey. (Deaton, et al, 2012).

Another way to engage younger students with role play is through the context of a scientific issue through a case study. When students are presented with multiple opportunities to research environmental science content and allowed to research issues that are relevant and meaningful to their community, their science content knowledge improves. When they have purpose for their learning or think about how it can impact their neighborhood and/or community they become engaged with their learning. In one case study, students learned about a local environmental issue impacting the community (algae in the lake). In using role play and case study to research environmental science students in this case added to their science content knowledge through research or inquiry investigations about the issue through examining environmental issues in their agricultural community (Deaton & Cook, 2012). The goal of this role play/case study could be enhanced through TELE. As part of the study students were required to research science content, and participating in role-playing which could be enhanced through well designed simulations or virtual reality.

Role play should be developed in the science classroom as a way for students to engage with their learning, learn to understand and share alternate perspectives, and foster communication, problem solving, decision making and critical thinking skills.

Synthesis of Anchored Instruction, SKI/WISE, LfU and T-Gem

Synthesis of the Four Learning Environments Explored- table

The link provided (table) is the synthesis that I’ve created to compare and contrast the four learning environments explored in our course including Anchored Instruction, SKI/WISE, LfU and T-Gem. I did find MANY overlapping ideas/tenets and I also feel that as these learning environments change based on upgrades, new understandings and student/educator needs that more overlap is inevitable. I do think that each technology supported environment provides its own “positives” depending on the style of the educator, the needs of the students, the age of the students and access to technology. In addition, timelines must be considered and I believe each of these requires more time to allow students to find relationships, deepen their understandings, communicate with each other and reflect on their learnings, and even more time if they are to apply these understandings in real-world contexts. That being said it cannot be understated that these environments provide deep, rich understandings.  In addition, I would like to add that supporting and educating teachers to use these valuable resources should be a goal so that science/math education can continue to support deep, engaging and meaningful learning for students.

Since I am an elementary educator I would also liike to put forth that these should be used in the early grades so that students can begin to consolodate their scientific understandings before “the damage is done”, so to speak. What I mean is that it seems that many misconceptions re: science concepts are formed in early learning and providing for engaging science problem solving and investigations that address these misconceptions would go a long way in hopefully curbing this trend. That being said, just using “technology” to teach scienc e is not a panacea, as there is much misinformation represented in a variety of science vidoes, interactive games, etc. online that is purposely “dumbed down” to be accessible to younger students. In addition, the ideas about technology integration held by the educator cannot be overlooked, as these understandings can colour how the technology is implemented. We need to be cognizant of this as educators and work towards adapting sound technologically enhanced learning environments into our early elementary classrooms.

Refraction of Light and T-Gem Principles

One challenge for students is to understand the refraction of light.  For example, when a student observes a straw in a glass of water, the straw looks like it is bending. This is due to the properties of light, but this understanding can be fraught with misconceptions regarding how light behaves. Some interesting misconceptions about light may be that water does not reflect or absorb light but light can go through it, light always passes straight through transparent objects (without changing direction) or that light needs air to travel (Sampson & Schleigh, 2016).

Research notes that although light is an everyday phenomenon that we constantly observe, students often display learning difficulties and hold unscientific understanding on physics concepts of light wave (Srisawadi & Kroothkeaw, 2014). In addition, concepts of light such as its speed and wave length are removed from the range of perceptions of the human senses, and so optics instruction can be subject to interpretation, so there is a need for careful consideration in physics teaching process (Srisawadi & Kroothkeaw, 2014). Computer simulations can broach this divide. As noted, computer simulations can enhance generating relationships and allow students and teachers the opportunity to view trends, variables and visual representation  in more concrete ways which may lead to more accurate conceptual understandings (Khan, 2011).

In order to generate information about this phenomenon the educator can begin an open-ended discussion to find out current concepts about light. Questions such as:

What is light?

Where do you think light comes from?

How does light travel?

This will allow the educator to begin to understand what conceptions and misconceptions the students may hold about light and will also allow the students to begin thinking about the concept. As this discussion is occurring the educator can note responses on chart paper or interactive whiteboard so that ideas can be reviewed as the process of understanding continues. As an educator I would incorporate “accountable talk” which will allow students to defend their ideas and question others about their understandings. Examples of accountable talk would be statements like;

“I wonder why….?

“I see what you are saying (rephrase)”

“What you said made me think….”

Then as an educator I would facilitate a review of the ideas generated in the group discussion through referring and restating the list created by students. I would break this down further into “Our First Ideas about Light” and then create another section for questions we now have about light. This would be labelled “Our Questions about Light”. We would brainstorm some questions that we have. Then I would provide students with appropriate books and internet resources about light. I would also show them a model or a picture of a straw in a glass of water. The straw appears to bend and so I would ask them how they would explain the phenomenon. After they have a chance to read/view this information, I would ask them to work with a partner, independently or in a small group (provide choice) and to draw or create a clay model of their understanding of light.

We would then reconvene and compare our models. I would give students time to explain their models to their peers so that I could continue to assess possible misconceptions. At this point the students may begin to reformulate their understandings based on new learning from their peers. Then we would watch several simulations about light refraction. I would ask the students to consider their previous understandings by asking “Do you need to change your original drawing/model? Or “Do you think you need to modify your original drawing/model?”  Our new understanding would be discussed and a new category would be added to our discussion titled “New Understandings”.

Technology, Learning for Use and Supporting Students in Science

After reading and reflecting on the aims of LfU (Learning for Use) I believe there are a number of ways that LfU has the capability of supporting students who are experiencing conceptual challenges understanding Earth Science. The main goal of LfU experiences are to seamlessly integrate content and process activities so that students achieve robust and useful understandings that are deep and accessible (Edelson, 2001). In particular, technology supported inquiry learning provides an opportunity for these students to be supported throughout their learning. The Create-a-World Project which includes the use of the programs WorldWatcher and Progress Portfolio demonstrate a robust example of how technology can be used to support these learners. WorldWatcher provides a geographic visualization and data analysis engine whereas Progress Portfolio provides a place to record and monitor investigations and capture the ongoing work done in Worldwatcher.

The objective of the  Create-a-World Project is to have students investigate relationships between temperature and geography from a climatic perspective. Since this project is designed with the LfU model it follows certain protocols. Most importantly LFU focusses on the application of knowledge and through a knowledge application task LfU creates demand for learning and offers space for refinement as students apply knowledge they have learned (Edelson, 2001).  Reflection is also built into this process and a necessary part of the learning cycle. LfU is similar to the traditional learning cycle in which students are involved in an exploration or activities that help them understand a concept. This includes hands-on observations, measurement and gathering of evidence. Through this process, students begin to explore relationships and concepts and/or discuss findings and finally additional observations are discussed, noted and shared then applied and refined.

Examining a knowledge application task will illustrate the process and how technology can support the aims of LfU. In the introduction of the Create-a-World project students are inspired to begin to think about global temperature through guessing and colouring in the average temperatures in the world in July. This is to start the discussion about the concept and to promote communication. The LfU reasoning for this is to elicit curiosity and to have students confront limitations in their understandings (Edelson, 2001). It is noted in other literature that students are not likely to change their understandings in science until they notice contradictions to existing ones and that constructing relationships is a way to breach this divide (DeLaughter, Stein, Stein & Bain, 1998).

In step 2 students compare conjectures using WorldWatcher using real data. They use visualization and analysis tools to compare their own maps with actual July temperatures around the world. The LFU reasoning for this is that this allows students begin to observe patterns of temperature variation and to elicit curiosity in their causes (Edelson, 2001).

In fact, deeper more robust learning occurs when we encourage students to pursue a concept in a variety of contexts and examples until these new models are integrated. The students need to understand why they are pursuing the problem and this is best achieved  when students encounter information in the context of pursuing larger problems and  issues that they find intriguing (DeLaughter, et al., 1998)

In step 3 the students invent their own worlds using a paint interface and data sets. The LfU reasoning is to create a demand for student learning. Students must have an understanding of temperature to create this world.

In activity 4 students begin to explore the relationship between geography and temperature using WorldWatcher tools. The maps created are inputted into the Progress Portfolio program and they are able to annotate the relationships they see. Then they engage in group discussions in which they further refine their understandings. In this way they acquire additional knowledge construction.

In activity 5 the students begin to explain findings through discussions and have the opportunity for hands-on laboratory explorations of concepts thus explored. At this time the teacher can offer explanations or address misconceptions.

Finally, in activity 6 the students create temperature maps for their created worlds based on all the factors they have studied. They also document the rules they are using while creating these maps and record these in their progress portfolio. Then they present to their classmates and explain their work and have an opportunity to discuss the reasoning behind their choices.

So after outlining this example, here are the ways that I believe that LfU has the capability of supporting students who are experiencing conceptual challenges understanding Earth Science. Firstly, LfU design creates demand for learning and eliciting curiosity. In the Create-a-World project the students are required to create a fictitious world, and this would be the impetus for learning about temperature and climate. The technology used in WorldWatcher allows them to paint data and manipulate data for this purpose. So technology is supporting this type of learning.

In addition, eliciting curiosity through identifying potential misconceptions and for activating existing knowledge is achieved with technology. Technology provides simulations which may be unavailable to direct observation (Edelson, 2001). Technology may also provide ways to articulate and demonstrate concepts using, for example, drawing programs.   Eliciting curiosity may not happen with traditional style lecture or through textbooks which often tend to be outdated or misrepresent scientific concepts.

As students continue to discover more about scientific concepts and delve deeper with their understandings, technology can assist with data collection and analysis, modeling, and prediction which may be hampered without these technology tools due to time constraints, lack of resources or complex data management capabilities.

The computer is also used as a communication tool which provides the ability to present information in a wide variety of formats, which may not be possible in traditional presentations. This not only allows for differentiation but also allows for students choice, both aims of educational reform.

Finally, technology provides a place for reflection. It supports record-keeping during inquiry and also provides for the possibility of ongoing discussion threads for communication as well as presentation tools. In addition, investigation tools are provided through visualization and analysis capabilities, artifact construction, expressive and record keeping data collection and tools such as annotation as well as drawing capabilities.

Reflections on Anchored Instruction Posts/Discussion

 

After reading through the myriad of posts in the Anchored Instruction portion of module B several themes seemed to stand out. When discussing the Jasper Series videos the value of this type of teaching and learning was evident. My peers spoke to the abstract thinking that is an outcome of learning. In addition, the positive learning that occurs through collaboration, having an authentic purpose for learning, engaging students, a student centered and constructivist approach and scaffolded problem solving were all hilighted.

On the other hand, many also alluded to the possible drawbacks to using this style of teaching/learning. The lack of teacher understanding of how to use the videos effectively surfaced, as well as the problems with lack of technology training for educators, which may leave them at a disadvantage when attempting to incorporate anchored instruction using these videos or technology in general.Several peers also mentioned that these videoes were a bit outdated and that newer technology(ies) could provide the same type of anchored instruction. Virtual reality was suggested, as well as videos that are even more interactive and open-ended.

It was interesting to read that several peers were attempting to integrate anchored instruction in their own classrooms but tailoring it to meet both their own needs and the needs of their students. I think seeing the videos provided some with a springboard which they could then use to change or start to change their math program. If nothing else, the videos provided a new way to look at math instruction and although there would be a learning curve before fully integrating this type of instruction in a classroom, many felt that anchored instruction and using videos would be a valuable component of a student centered classroom.

I still have questions about evaluation/assessment as well as how to properly scaffold group work and collaboration. I believe in constructivist teaching/learning but I also understand that it is not a linear way to teach and learn and it takes a lot of work and flexibility in approach. This may not be comfortable for some educators and having a mentor to help them through developing a classroom with anchored instruction components would be beneficial.

Considering WISE Design and Jasper Adventures

Wise research aims to bridge the gap between the research that shows the efficacy of inquiry learning in science and the method in which science is generally delivered. In science specifically it has been found that students have many misunderstandings developed either through experiences, concepts or examples (Linn, M., Clark, D. & Slotta, J., 2003). In order to address these, WISE curriculum projects promote knowledge integration through providing inquiry projects which are flexible, customizable and adaptive. They also believe in sustainability. Through field testing and multiple cycles of trial, adaptation and refinement the inquiry projects are continually honed to meet the specific needs of the students. In this way WISE is a bottom up approach rather than a top down approach and is meeting the educational goal of delivering curriculum in a differentiated way, which is one of the goals of education.

In addition, WISE supports the provision of an instructional pattern to assist students through the inquiry. These include eliciting student ideas, adding ideas to these and supporting the process learning to improve understanding. In this way WISE is able to scaffold the students’ learning in an indirect way, while still providing them with many pathways to reach their conclusions. WISE guides the students through the inquiry project without being prescriptive, which leads to deeper learning.

In addition, WISE project teams are made up of diverse partners so as to provide a more holistic inquiry. These include pedagogical specialists, scientists, teachers, and technology designers. WISE framework design principles include making thinking visible, making science accessible, helping students learn from each other, and  promoting lifelong learning, all goals of 21st century education as well as sound pedagogy.

Further to this, many WISE inquiry projects have been designed with detailed steps for the first inquiry investigation and then providing less detailed steps in subsequent projects. In this way students are able to move from supported learning to more independent pathways. This method is debated. When considering the Jasper Series, the belief that students can develop basic skills in the context of meaningful problem posing and problem-solving activities rather than isolated “targets” of instruction seems to refute this. That being said, the Jasper Series coincides with WISE with its emphasis on complex, problem solving, communication and reasoning and in connecting mathematics to the world outside the classroom. (Cognition and Technology and Technology Group at Vanderbilt, 1992).

Looking at this more closely in WISE design it has been found that students prefer to not have a lot of detail before they begin their inquiry, but rather work well with an  initial page that provides an entry into the disciplinary knowledge and provides hyperlinks for students who wish more detail. In this way, making science accessible may not mean making it simple (Linn et al., 2003). This mirrors the anchored instruction shown in the Jasper Series as well.

Another link between the Jasper Series and WISE seems to be the belief that the educator should be a facilitator rather than the disseminator of information. In WISE an inquiry map helps students work independently on their project with prompts that help guide through process. Teachers can also easily customize the projects to match their curriculum and students.

The flexible, continually changing approach to WISE is based on the need for scientific materials that enable local adaptation along with support from multiple cycles of trial and refinement. Students’ needs and what scientific inquiries which engage them are also closely considered. Providing students with content they are interested in and that may have an impact on them is part of the real-world problem solving that is encapsulated in anchored instruction.  This continual refinement is also found in the Jasper Series. Technology can provide for this, whereas traditional textbooks cannot. Furthermore new technologies can be integrated into WISE and the system itself scaffolds the use of offline activities by providing a project context, a pedagogical framework, and proven curriculum design patterns.

Customizing WISE would be beneficial. If I were to use any of the inquiries I could integrate the climate and realities in Northwestern Ontario or the Canadian Shield. In addition I could integrate information about Lake Superior, one of the largest freshwater lakes in the world, which is situated in Thunder Bay (the students’ hometown). Local flora and fauna could be considered. The seasons and the weather locally could also be integrated. These are just some examples.

Mathematics Instruction for Students with Learning Disabilities-Jasper and Reflections on my Teaching Practice

The article, “Mathematics Instruction for Students with Learning Disabilities: A Meta-Analysis of Instructional Components”, helped me to further analyze the Jasper series and its goals. Within this study the researchers sorted the studies by major types of instructional variables. Their interest was in the detailed curriculum design and teaching practices that resulted in enhanced mathematics and they focussed on the essential attributes of effective practice. They went further and defined “explicit instruction”, which in previous research has shown positive effects in terms of increased understanding of mathematical skills for students with learning disabilities. The researchers broke it down into three components: (a) The teacher demonstrated a step-by-step plan (strategy) for solving the problem, (b) this step-by-step plan needed to be specific for a set of problems (as opposed to a general problem-solving heuristic strategy), and (c) students were asked to use the same procedure/steps demonstrated by the teacher to solve the problem (Gersten, Chard, Jayanthi, Baker, Morphy & Flojo, 2009). They also looked at the methods that exemplify a generic approach for solving a problem, student verbalizations of their mathematical reasoning, using visual representations while solving problems and range and sequence of examples. They further investigated providing ongoing formative assessment data and feedback to teachers on students’ mathematics performance, providing formative assessment data and feedback to students with LD on their mathematics performance and peer-assisted math instruction.

The results of the meta-analysis rendered some interesting data. Firstly, peer assisted learning did not provide much benefit, whereas being tutored by a well-trained older student or adult appears to help significantly (Gersten, et al., 2009). When assisting students with LD in my classroom, this finding is important, as I often pair my students with LD with their peers in order to provide more scaffolding or scaffolding when I am busy helping other students. I will need to rethink this approach.

In addition the two instructional components that provided significant benefits were teaching students to use heuristics (a process or method) to solve problems and explicit instruction (Gersten et al., 2009). When reflecting on these findings I still have some questions. I do teach my LD students a certain process or method to solving mathematical problems but I also don’t want to limit their strategies as we are being told to allow them to explore mathematical problems with a variety of strategies. Now that I think about this, perhaps students with LD do not benefit from a variety of strategies but are best served with a limited number of strategies to use, at least initially. In terms of explicit instruction, I do provide this to my students with LD, although they are also part of any open-ended problem solving that we do in class. I feel it is important to expose them to this type of mathematics as well, but perhaps they would be better served working on other math during this time. That being said, the researchers found that explicit instruction should not be the only form of instruction, so perhaps I should continue to expose the LD students to our open-ended problem solving discussions.

They also found that the sequence of examples is of importance when new skills are being taught, so scaffolding is critical for student success. Examples and problems should move from simple to increasing complexity (Gersten et al., 2009). When reflecting on my own teaching, I find that I do this naturally with all students, as it makes sense to me to move from simple to more complex problems. That being said, and reflecting on the Jasper series, perhaps introducing complex problems that students have to work through and problem solve through may be of more benefit.  The Jasper experiment believes that engaging students in real-world problems that are inherently interesting and important helps students understand why it is important to learn various sub skills and when they are useful. The Jasper adventures are purposely created to reflect the complexity of real world problems (Cognition and Technology Group at Vanderbilt, 1992).  As part of inquiry teaching (a method I use to teach some of the time in my classroom), I often introduce mathematical problems based on math explored in read-alouds. For example, when reading the book “Iron Man” we explored measurement as we explored how big we thought the Iron Man, the science fiction character in the story, would be compared to us as students. So in this way I attempt to introduce concepts that lead the students down possibly unexplored mathematical pathways and see what they can produce. I am left with the wondering: Do LD students benefit from this?

Importantly, the study showed that the process of encouraging students to verbalize their thinking or their strategies, or even the explicit strategies modeled by the teacher, was always effective (Gersten et al., 2009). In my teaching practice I often use verbal understandings to gain a better understanding of student understanding/misunderstanding and for ongoing assessment to move forward. I do this for all students, but particularly for students with LD.

It appears that teachers and students also benefit if the teachers are given specific guidance on addressing instructional needs or curricula so that they can immediately provide relevant instructional material to their student.  Teachers require support!!  This is an important point to discuss as educators are often expected to know what to do in all situations with a variety of different styles of learners, with a variety of curriculum and with a variety of learning abilities. As Schulman (1986) noted in his research, teacher training and the type of training provided needs to be revised to reflect both content and pedagogical knowledge.  The fact of the matter is that educators do not have all of these skills and cannot devote the amount of time required to meet the needs of all students. Teachers require the supports of special education teachers, administration, professional development, etc. in order to gain and implement these skills.  The research further disseminates this as the researchers recommend that providing specific instructional guidelines and curricular materials for teachers  and co-teachers or providing support services, peer tutors, cross-age tutors and/or adults providing extra support would be of direct benefit to students with LD (Gersten, et al., 2009).

Interestingly the researchers found at there seems to be no benefit in providing students with LD-specific feedback that is specifically linked to their goal attainment (Gersten et al., 2009). This seems to refute the feedback loop that we are encouraged to use as educators in order to help students to move forward in their learning. I will have to consider this when providing feedback to LD students. Perhaps spending more time on heuristics and explicit instruction and use of visuals would provide better scaffolding for their learning. I look forward to your thoughts on these points.

Schulman and PCK Reflections

In Schulman’s reflections we see the recent development of a distinction between knowledge and pedagogy. The idea of teacher competence has shifted towards competence with pedagogy rather than the historical view of teachers as the holders and disseminators of knowledge.  With the emphasis  on classroom management, organizational skills,  assignment creation and questioning formats, planning and assessment strategies Schulman proposes that an important piece is missing. We should be asking  questions about how the content of the lessons is taught. The important questions of where teacher explanations come from, how decisions about teaching are made, how to represent content, how to question students and how to deal with problems of misunderstanding are integral to sound practice. He proposes that by asking these questions we can begin to build information that can address gaps in these areas.  Content deserves as much attention as the elements of teaching process.

 

He disseminates this further, breaking down knowledge into 3 components: content knowledge, pedagogical content knowledge and curricular knowledge, all of which should be robust for education to be rich and for an optimal teaching and learning environment.

In my own classroom I am currently teaching the concept of time to grade 2 students. When teaching this concept, the background knowledge in skip counting by 5’s and well as previous understanding on time to the hour both on analog and digital clocks is helpful. It can be a difficult concept for some students because the numbers on the clock 1-12 also correspond with skip counting by 5’s all the way from 0-60. The hour is 60 minutes, there are 5 minutes between each number on the clock. So, there are a lot of competing mathematical ideas for young children to simultaneously understand. In addition, there are several different names for time. There is 6:30 and half-past 6:00. There are 6:45 and a quarter to 7:00. In addition, with a heavy reliance on telling time digitally, for example on a mobile device, many parents are not discussing time or telling time using an analog clock at home. Yet, it is still in our  curriculum.

When I teach time I usually have the children construct a model of their own clock with paper and this is a scaffold for them as we begin to explore the concept. In grade 2 the curriculum asks for us to explore 15 minutes on the clock, so 6:15, 6:30, and 6:45.  I begin by reviewing time by the hour and having a discussion with the students about why it is helpful or important to learn to tell the time. We brainstorm ideas and discuss this. Then we begin to map out different important times within the day at school, nutrition break, lunch, recess, etc. On idea I have been reflecting on lately is the fact that time is viewed different within different cultures, and I would like to explore this more fully as I am only teaching from my perspective of linear time. Some cultures believe in circular time.  This brings me back to PCK.  Just because an educator has knowledge of something does not mean it will fit within the structures of our school. Time is limited and decisions need to be made based on many factors.

Digitally I use an interactive clock on the smart board to practice telling time, and I also have children engaged in time games which helps solidify understandings in a fun way. Telling time is a skill that can be taught in school, but for it to be useful the students need to “need” to use it in real ways in their lives. So I introduce the concept, allow them to try using it in school and hopefully in grade 3 and so on they will continue to grow in their understandings and ‘need” to be able to tell the time.
