Special Angles Hand Trick

Never liked the use of special triangles to remmber the trigonometric quantities for special angles. also, special triangles are not convinient for such angles such as 0, 90, 270 and 180. Found another great way to remmeber the values! vaery visual and works for ALL special angles

however, still fancy unit circle 🙂 Too bad not many schools teach it

Just one more another way to solve quadratic equations

quite interesting way to look at the way to solve quadratic equations

CATL Post-Practicum (Teaching) Reflection #4

  • Course: EOSC112
  • Date: April 1st, 2019
  • Class Size: ~200 people
  • Topic: Future climate

During my teaching practicum during term 2, I decided to teach two consecutive classes on a similar topic. During my previous lesson, I introduced students to climate models and the process of how models are created. During my next class, I wanted to build on their experience and introduced them to a more complex “real-life” climate model that has been used to predict the future of the planet for the next century.

This class was designed as a lecture-based session (with clicker participation). Although, l could have been more creative and structure the class differently. I think I reversed to my most comfortable way of teaching (but not the optimal one) due to lack of time to prepare for it properly and also, I was afraid that doing worksheet activity gain would be too much for the students. Thus, if I am going to teach this section next year, I want to create something more hands-on for the students, rather then just lecturing.

Throughout the lesson, I tried always referring them back to the previous class, to build on students’ experience and show them the link between what they did with what they are studying now.  I also added a clicker question, asking students to choose the most effective way/ action they can take to reduce warming (reduce CO2 in the atmosphere). I gave them a list of options. Then I showed them the infographics (see below) with the actual impact they will make with their action. Through this activity, I wanted to emphasize the importance of personal choices/ action on the future of our Planet. Unfortunately, most of the actions at UBC are focused on the importance of recycling. Although it is a crucial step we need to take, such action is not enough to mitigate a drastic temperature rise in recent years. So, I wanted to share this idea with students to introduce a sense of urgency and to empower them to do something more than just our convenient behavior.

The thing that I think went wrong:

  • I was too nervous, and as a result, my pace was too fast, and we finished 10 min earlier than expected
  • I did not explain the graphs properly (pointing out the axis, units, explaining each line)
  • My gestures were hectic, and my hand movements were excessive

The course instructor, Dr. Waterman, was observing me during the lecture> she identified several strength and weaknesses in my presentation.

Strengths:

  • She appreciated the worksheet I designed, she commented on a  great design; appropriate level; and that it was well-timed and was well-executed.
  • she also commented on my proficiency in utilizing active learning techniques (clickers) during the lecture. She also noted that I did a great job in reacting on the spot to student responses and targeting my lecturing accordingly.
  • Dr. Waterman also commented on my ability to design/ update the lecture materials for the course. She said that the content was excellent because it was current, high quality and diverse (e.g. IPCC projections, as well as how personal choices impact one’s carbon footprint). She also mentioned that I was very responsible in posting helpful class resources in a timely fashion.

Suggestions for improvement:

  • The clicker questions for the worksheet debrief were perhaps a little too easy to be optimally effective and maintain engagement.  She encouraged me to continue to experiment to find the right balance between being affirming and challenging/engaging students.
  • It appeared sometimes challenging for me to keep all students attentive during the frequent shifts between group work and debrief for the worksheet exercise.  It is challenging to have to try to repeatedly bring students’ attention back to the front.
  • Dr. Waterman also suggested to project your voice more and/or turn out your microphone amplification.

CATL  Post-Practicum (Teaching) Reflection #3

Course: EOSC112

Date: March 29, 2019

Class Size: ~200 people

Topic: Future climate

I am continuing to challenge myself to change my lecture style from instructor-focused to student-centered teaching. During my 1st teaching practicum in Term 2 of CATL program, I decided to teach a class that I have been TAing for 5 years. The course schedule has been modified this term, and as a result, an additional class in the last module of the course, The Future Climate, was added to the class schedule. As the previous years only contained 3 lectures per module, there was a need to design an additional one. I was assigned to collect the additional material on future climate section and update already existing lectures with up-to-date information. As a result, I thought it will be a great opportunity for me to implement what I have learned during CATL in designing a lesson.

I was trying to structure my lesson in the form of activity that was leading students through the Kolb’s cycle. My activity was consisting

            Stage 1: Plan
(Kolb’s “Active experimentation”)
Students were given the following task: Your group is part of the US Department of Climate Change. The American government has requested that you make an assessment of the cost-to-benefit ratio of different policy approaches to reducing future warming. Your goal is to predict what the temperature will be in the USA in 2050 under different policy scenarios, and advice on the best policy option.

Each group was given 5 different graphs that showed the change since the 1800s. Students were asked first to explore the trends and describe them in their worksheet. This step was designed to make students familiar with the data. During the next part, students were exploring how exact the same parameters were changing with temperature.  This step was created to make students think about what parameters should be included in their model. They were also asked to make a rationale why they want to include a certain parameter in the model and why not.

Stage 2: Experience
(Kolb’s “Concrete experiences”)
Then, students were asked to create their own model based on eth parameters they chose earlier. To do that they were asked to “predict” the value of the parameter in 2050. To do that, students were using the graph from Part 1, but were required to use some sort of logic/rationale, as the trend finishes in 2018. Students were encouraged to discuss what may happen in the future using past and present trends. Then they were using the temperature graph to see what the temperature would be given the value of parameter from 2050. At the end they came up with the estimate of the temperature in 2050.
Stage 3: Reflect
(Kolb’s “Reflective observation”)
The next stage of the lesson was making students to reflect on their model. To do that they were given two scenarios that described what government can do to mitigate the warming. Option one was very expensive, but most effective; while Option2 was less expensive and not as effective as Option 1. So, students were encouraged to choose one option that government should implement. As there was no “correct answer” in this situation as they face a dilemma that all governments are facing in real world: to go what is less expensive or the one that works best (but is more expensive) option. Thus, this part gave them an opportunity to share their own values and beliefs.
Stage 4: Conceptualise
(Kolb’s “Abstract conceptualization”)
Students were asked to evaluate their Model: to emphasize strong and week points. And also suggest how they can improve their model if they were asked to do it once again (e.g. What other parameters to consider)

During this lesson I was trying to accomplish the following goals:

Channel A

  • DEVELOPE a simple climate model
  • COMPARE different policy outcome using simple climate model

Channel B:

  • To understand the uncertainty in human action (predicting how parameter will change in 2050)
  • In reality, the best option is not usually the one that is most effective, but that is more affordable.
  • There is multiple of possibilities when we talk about future
  • You can only work with what is available, but not with what is needed.

Overall, the activity went well. The timing of each part was in good pace, with no rushing at the end (which was very surprising as I usually tend to over- budget the activities I crate). Students seemed to be very engaged in the discussion, but for the next year, I would make the writing portion a bit more condensed. Also, I was suggested to modify the model slightly to make the estimates a bit closer to the real world.

Post-Teaching Reflection #2

During my teaching practicum I wanted to achieve the following goals:

  • Teach a large class
  • Improve the class activity
  • To improve my class management skills

I decided to teach a large class as most of my teaching experience comes from teaching small classes (30-40 people), so that is why I chose to teach an EOSC 114 class with ~260 students. I also chose this class as I am unfamiliar with subject material, thus during my class preparation I would need to work both the PCK and PK aspects of my teaching.

I also wanted to gain more experience in designing and improving various activities for teaching, as I am going need this experience during my CATL project. During the class, I was responsible for teaching part of the lecture ( 2 lectures, morning and evening classes)  where students are doing a worksheet exploring the effect of the meteor impact on the Vancouver area. The way the worksheet was originally designed is that students enter the provided parameters into the meteor impact simulator ( a website that calculates the effect based on the input parameters) and explore how it affects the magnitude of the impact ( i.e. building, earthquake strength and etc). However, I found this set up is a little bit disengaging for students as they just follow the instruction without going through the KOLB cycle.

Thus, I created a worksheet consisting of two parts:

  • Part students get familiar with how to use a simulator and where to extract the data for their further work. I played around with various parameter settings and came up with the set of parameters that produce the meteor with various impacts (i.e. large earthquakes, huge thermal radiation that will result in ignition of paper, the collapse of poorly structured buildings and many others for students to explore). Although the initial conditions were fixed, I let the students decide themselves what kind of data they want to record (e.g., I asked them to choose the events that are the most dangerous or something that students find interesting). Thus, students did not just copy the results of the simulation but filter the information obtained through the website and use the judgment whether something was worth recording or not.
  • Once the students were familiar with how using the settings, I asked them to design their own experiment where they can explore how a change in one input parameter will affect the impact on Earth. Students were free to choose what parameter to change (meteor diameter, an angle of collision with Earth, density or velocity of the meteor) and to explore the changes. I also constructed the worksheet in a similar way they would write their lab reports: starting with the objective, then the table where they record their input parameters and decide what they change and what things they will observe, then a place to record their observations and lastly a small conclusion of their experiment.

I found this activity to go quite well, students seemed to be very interested in the topic and were experimenting with various setup. I also asked students to work in groups of 2-3 people that also make the activity more engaging for students.

The highlight of this activity for me was a bit unexpected but in a good way. While designing the worksheet I was trying to find parameters that will result in the generation of tsunami, but I could not find any to achieve even a small one. After reading certain posts/documentation to the program, I found that those features were not yet available. However, during the class, one group find the optimal parameters to generate a tsunami and students were very excited to achieve smth that I thought was impossible. I think that this was one of the best outcomes from my classroom where students exceeded the expectation and even did a better job at exploring than their instructor.

During my first teaching practicum, I found myself to be extremely nervous, even though I was teaching a smaller class. However, while I was teaching this course I found myself to be more relax and more confident in what I was doing. I did not have a problem in answering students question, asking students to share their observations and generally to hold student attention. However, I think I was more confident because I was co-teaching lecture and my mentor who was present in the classroom. that is why for the future, I would like to conduct the whole lesson myself to make sure that I can manage and conduct the whole lesson without the presence of any senior instructors in the room.

Some of the identified drawbacks of my teaching

  • I found that teaching 50 min class is way harder than teaching a 3hr ones as you need to be very efficient in the way you teach and n the way you structure your lesson
  • As a result, the worksheet I created was a bit long and thus requires to be cut in half for future use.

Post-Observation Reflection #2

“Brett is awesome….he is the reason why I decided to make a career out of Geology….”

Students review from ratemyprofessors.com

Last week I was observing my mentor, Dr. Brett Gilley, teaching an EOSC 114 class. This a large (~260 students) first-year level course at the department of earth and Ocean sciences where students being introduced to various Natural Disasters and how to prevent them. The topic of the lecture I was observing was Landslides.

I think one of the strengths of my mentor is the class management skills. I don’t think I have ever had a person who was able to manage the 200-people class so effortlessly. In addition, Brett is extremely passionate about what he teaches and have great skills in engaging students in dialogue with him during the lecture.

I think what is very different about Brett is that his lecture starts way before the official class start time. When I came to the classroom, he was already playing videos about the landslides, and he was chatting to students sitting at the front row. I think that this is a sign on expert rather than novice instructor. Personally, I always seem busy at the beginning for the lecture making sure I have everything I need, whether everything is working properly and hardly initiate any conversation with students who came to the classroom earlier.

Playing movies, I think is a great idea that helps better manage the class. I observed students sitting calmly watching a video rather than start talking to their peers. Such a technique also engages people into lecture material as it provides relevance and connection to the real world problems/events.

I also find it quite interesting to observe Brett teaching students with disabilities. There was a person in the class with a visual impairment attending the lecture that was primarily made of pictures and videos of landslides. For me, it seemed impossible to meet the need of the student in such a class setting. Although the student had an assistant sitting next to him and describing what was shown on the slides. Thus, I was wondering how much the students can learn from such experience.

I find such situation challenging as I had a similar experience in teaching a lab. Student assistants helping the students usually do not possess the required background knowledge (i.e. see things through the eyes of the practitioner in this discipline) and, as a result, can describe something different or irrelevant for the lecture.  During the lab I was teaching, the assistant usually described a lot of features to the student and did a very good job in all the details, but often missed important features or characteristics of rock samples that could only be spotted by people who had some background in the area. That is why I was very crucial to see how Brett handle this kind of issues in his classroom/

I find that Brett was very caring and understanding towards the need of this students and regularly checked on him re-describing the things that were shown in the figures or played in the videos to make sure he gets the scope and the main ideas. During the class, he was also very detailed in his explanation and description to make sure that he pointed out all the important features on the figures and diagram to make sure that the student can understand the concept and actually ‘visualize” the pictures without seeing them.

This is a word cloud generated from the student’s feedback on Brett teaching from ratemyprofessors.com.

One of my weaknesses in teaching is a class management skill. That is why I was particularly interested in this aspect of Brett teaching. During our chat after the lecture, Brett told me that to gain such participation levels from students you have to set it up right at the beginning of the course. This way students already trained to participate/ask questions during the lecture because they know the consequences of not doing so. That is why for my net observation practicum, I would like to attend the first lecture taught by Brett to be able to see how he set up the classroom and develop this participation level in this class.

CATL Post-Practicum (Teaching) Reflection #1

During my first teaching practicum, I was teaching a 4th-year course at my department (EOSC470 Biological Oceanography). This is an upper-level course offered though EOAS Department at UBC where students are exploring the marine ecosystems, factors, and processes responsible for distribution and abundance of marine organisms.

I wanted to create a more engaging fun lesson as I noticed that the “level of fun” is decreasing with the increase in course level in my department. Thus, almost all upper-level courses in my department are primarily taught by lectures with little focus on any activities (with the exception of worksheets and small group discussions). On the other hand, the lower level courses have a greater variety of various activities that are more creative and engaging for students.

So, my goal was to challenge myself to teach a hard upper-level topic in a unique and engaging way. During the lesson, I was aiming to accomplish the following aims:

  • My challenge was to structure the lesson in the more experimental learning set up, rather than as a “standard“ lecture.
  • Simulate the “real-world” experience in a group discussion setting
  • Build up teaching confidence in teaching the material

Experimental Learning Set Up

I chose a topic of Estimation of Secondary Productivity. This is a quite complex topic that describes different methods how the secondary production can be estimated with the stress on the limitations and assumption of a given method.

I tried doing Experiential Learning lecture where the main role in the classroom was given to students rather than the lecturer. Thus, all the quality and the amount of information that is produced during the class is entirely dependant on the students. This is a completely new approach for me as I am more comfortable having more control over the class. Hence, My role was only to moderate the lecture to make sure that students understand their roles and the outcomes of this lesson and also help if I see them struggling during the activity.

Group Discussion Setting

I believe that all scientific discoveries and inventions are primarily done through collaborations rather than individual work. That is why I structured my lesson as a group discussion to simulate the teamwork in the scientific community. The goal was to compete for funding from a research agency to obtain the money to perform the experiment using one of the methods to estimate secondary production. However, to make the classroom experience more unique, I structured the group work in a game format similar to the “Mafia.”

Using my skills and experiences from a resource development for various courses, I designed a completely new game that I called “Science Mafia.” The game is designed to simulate the experience in scientific community and allow students to have an ability to practice the role-playing, skills. So each team had a chief scientist who was responsible for presenting the outcomes of their group work, reporters who helped taking notes and regular scientist that had various roles ( e.g., one scientist were more interested in the disadvantages of the method, the other was more interested in highlighting the significance of the method).

Example of cards for class activity

Thus, each student was contributing to the overall conversation within the group and while focusing on different aspects of the method that I wanted them to pay attention too. However, each group was doing only one method that they were assigned, thus, to make sure each group can learn about another method each of the groups had a “spy” whose role was at the end of the class to switch to another group and share with them everything they learned about other group methods. Thus, all groups had a chance to learn about all the methods. In addition, spies also could switch the roles their team members have so any one of them can end up with a different role each round.

Teaching Confidence

I have never taken any courses related to Biological Oceanography and of course, never took the EOSC 470. Thus, not only I am lacking the Pedagogical Knowledge, but also, I am limited by the Content Knowledge.as a result, I was not feeling confident in the material I chose to present. However, I made it as my additional challenge to become confident in things I had never done before or studied myself.

To make myself more confident, I designed a lesson plan where I scheduled minute by minute activities and wrote down specific steps how to conduct the activity, how many minutes each step of the activity should take to make sure I have enough time to finish the exercise. To have a certain structure in the class, even though the outcome of the lecture will primarily lay on the students allowed me to have a certain control over the group dynamics and the course of the lesson.

Disciplinary Behaviours

I was trying to emphasize the following aspects that are common in my area:

  • Independent work. students were expected to read and analyze paper on their own and make a summary based on the given questions given
  • Group/ collaborative work. During the classroom, students were role-playing the “scientific ”
  • Proficiency in Analysis of the scientific literature, limitations, and assumptions

However, to make sure that students can pay attention to these behaviors, I wanted to make sure that they have some background knowledge in the studied topic to have enough confidence actually to practice these behaviors. Students also need to have a certain level of expertise to find certain activity effective. Thus I asked them to read a paper and do a small analysis before coming to class. As the class is made up of 4-year students, I felt that this wouldn’t be very problematic for them as they have been already trained in how to read and analyze the scientific paper.

Short Coming and Future Work

Overall, I think the class went OK. I was happy with the amount of work being done during the group’s discussion and the level of participation ( in general) of the students in the actual material. I also asked the students to give me a written anonymous feedback on my lecture. Based on the feedback students liked the following aspects of my teaching:

  • Interactive class, funny set up and engaging activity
  • Papers were straightforward to read
  • Good public speaking
  • Clear
  • Well prepared

The following shortcomings have been identified:

  • Improve the motivation of students to “do their homework.” Although the lesson before it was emphasized that students have to come prepared for the class by reading a paper and taking notes, it seemed that only a few people accomplished it. Thus, next time I can stress out that the material that will be covered in class will be part of the midterm and they will only get as much material as their group work. Thus, poor participation and preparedness to the lesson may result in very poor material gathered during the class, and, as a result, will not be sufficient to get a good grade on the final exam. The other way is to make sure students are ready is to set up an online test/quiz that will allow me to ask students the required questions and make sure that their level of knowledge is sufficient enough for the participation in the classroom.

 

  • class management The other issue that I have been identified by my observer is the lack of class managements skill due to low self -esteem. I found it to be impossible to pose yourself as an effective instructor and hold student attention while you doubt yourself and your teaching style. As a result of doubting myself whether my lesson is “ good enough” for the upper-level class, I found myself to be extremely nervous, talking too fast during the explanations,

 

  • Flexibility. Also, for the future, I would like to learn to be more flexible in my teaching, as I over-plan certain things. For instance, I planned 2 min “breaks” where students were basically given time to rest from the actual material and participate in a conversation with peers. I thought that the would be highly desired for the students and will even take more time. However, I found that students were not engaging in any talks with each other or their conversation was minimal. Thus, I should have modified my lesson plan right away to shorten that break time and allowing more time to do a discussion on the studied topic rather than trying to push them to engage in those conversations.

 

  • Lesson Summary. To have a more solid summary at the end of the class was a requested thing both by the observer and students. Although at the end of the activity, the groups produced the worksheets that had a summary of each method. After class, I compiled all the material they had and uploaded all of their work on Canvas. However, there should be some sort of clear summary at the end of the class. Although I did mention about the information, they will be asked on the final exam, and what kind of things they supposed to know, maybe a summary slide would be nice to put on n my presentation so that students can access how well they performed during the class and how much they actually covered in their group.

 

Homework from CATL (Experimental Learning Session), Part B

PART B:

Identifying a connection between something in the world and a theory that is used to explain that.

In your next Observation:

  • If the instructor is talking about a theory, are they making the connection between a theory and a real-world application of the theory? If yes How?

From what I saw so far, the first year courses at my department are primarily based on this way of organization. First, the student has an intro slide that posses some important events and phenomena happening in the world. And then students are introduced to the objectives. So students first learn about the “theory” behind the phenomenon and only then asked to try to explain how this theory “fits” in the real world. The skill is mastered through various clicker questions and also review questions. In my future observation, I want to be more aware of this process, and to see in more details how it works.

  • If the instructor is talking about a concrete experience or phenomenon, are they making connections between that concrete experience and a theory in their discipline? If yes, how?

Although during the lectures, students explicitly go over the method and then an example is given how to apply it to the real world problem, through my experience as a TA, I find that the process to go from real-world example to theory is very problematic to students.  I find that the most confusing part for students who were attempting to do a review questions at home is to be able to see the underlying method behind. Throughout the course, students learn a lot of different methods and theories. Hence, once they are given some situation/ phenomena that they have never encountered during the class and asked to explain what a certain event will do to it, students are often are unable to answer it as they have no idea on what method to apply. How I can explain that? … I actually come to the realization just by typing this paragraph. I think what students fail to do is to be able to “read” the question correctly. What I mean is they don’t see a “key” words that can hint them on how to approach this problem. Once, you point it to them and ask what do they know about it they immediately can recall the theory/method that is linked to it.

Does the activity they are using to do either of the above cases help the students make connections beyond the particular application they having students experience?

I think the review questions are very helpful in bridging the theory and practice. However, I also find it to be the most challenging part of the course.

In my next teaching practicum:

I want to make sure I:

  • Identify a connection between something in the world that I am trying to explain and a theory that is used to explain that.

In my next practicum, I am planning on teaching students about different methods to estimate secondary productivity. By the end of the class students will be able to:

  • Describe 3 different approaches to estimate secondary production
  • Compare and contrast 3 different approaches
  • List advantages and limitations for 3 methods
  • Propose the best method to estimate secondary production under the given set of conditions.

Thus this class is specifically designed to link the “theory” or method to answer some question that exists in the real world.

  • How are you helping your students make that connection?

I will ask students to read the scientific paper that talks about the estimates of secondary production. I think reading this primary literature is a very effective tool to make students aware that all the scientific papers answer the certain question posed by their authors. Thus, I need to make sure students are aware of it. Originally, I created 5 questions/topics that students need to write down while reading the paper where I asked about the advantages and disadvantages of each method. However, I totally omitted to include the purpose of these studies. Hence, I am planning to add additional questions such as “ what is the purpose of the study?” or “ What is the underlying problem the authors trying to solve?”, so that students can pay additional attention to why they are reading this paper and why authors chose this method to answer their question.

  • Does your process help your students be able to make connections beyond that particular exercise? How does it do that? and if not, what can you do to help them be able to do that?

As a 4th-year student, I would expect them to be comfortable in reading analyzing the scientific literature. But I feel what is more crucial is to master the ability to criticize the paper and be able to compare them to another study. Thus, to help them master the ability to evaluate the effectiveness of each method I will also do debate/ group activity where students will have time to talk over about advantages and disadvantages of each method and then summarising it in a concise way to present it during the debates. I also want to make the whole process a bit closer to the real-life situation rather then a “classroom” set up, hence I will introduce more of the “role-playing” group activity where each student will have a certain role as a scientist to contribute to the whole team.

Post-Observation Reflection 1

“Question everything…until you don’t want to go outside of your house” M.Lipsen

I chose to observe one of my mentors, Dr. Michael Lipsen, during one of his lectures in EOSC 470 course (Biological Oceanography). I have been co-teaching a course with Michael for about 3 years and learned almost all my teaching skills from him. I think one of the great aspects of his teaching is the ability to engage students through the conversations with them. Thus, his class does not really look like a lecture rather as a dialog on a given topic.

Pedagogical Content Knowledge. In my teaching, I use many tools to make my teaching more engaging for students, as I lack the ability to keep their attention for a long time. As a result, I create a lot of visuals, activity sheets, group discussions, concept sketches, and other activities to keep the students focused. Michal, on the other hand, have an amazing ability to keep the attention of the students throughout the lecture without the use of any creative techniques or activities.

However, it does not mean that is teaching is boring or disengaging. His lecture was based on constant back and forth dialog between him and his students. Right from the beginning, he showed a photo of the ocean with various marine organisms that were collected from a local beach in Vancouver, asking students to identify the most abundant one. Such bridge-in activity engages students in inquiry process right at the start of the class.

Methods of the presentation. During the lecture, Michael periodically asked questions that either tested whether students remember the material from previous lectures (or courses!) or to engage them in critical thinking.  He also emphasized the point of critical thinking in learning, challenging students to find weaknesses and assumptions in the introduced theories as well as find the limitations of the proposed techniques and concepts. Thus, he emphasized that the dominant paradigm that existed in science were turned upside down because someone started questioning it.

Relevance. Michael is one of the few professors that I saw teaching who incorporates recent findings in his lecture. Most of the instructors teach the same slides for years, without changing much of the material. Michael can change his lectures a couple hours before the lecture because he found a very interesting article that has just been published. He is also up to date with all the new things that happen in the area and always mentions existing disagreements, new emerging theories to his students.

Flexibility. During the class he was also very accommodating, allowing the group of students who were going to present next week to hand in their assignments later as there was a Thanksgiving holiday during that week (so students can enjoy the holiday and not being stressed of submitting the assignment on time).

Student Learning. To make content relevant to the students, Michael provides many local examples so that students can better relate to the concept he is talking about. He is also one of the few instructors that emphasize the importance of memorizing the new terms/ concepts for both first and upper year courses. In his lecture, he provided a slide of all new concepts and vocabulary that have been introduced during the class and briefly re-emphasize the importance of each of the item in the list.

Beyond the classroom. He also encourages students to participate in the life of the department. He showed photos of the pumpkins from last year pumpkin carving contest in our department. He chose pumpkins that were carved in a shape of the organisms that were studied during the class. Although it seemed like a small distraction from the lecture, I think it actually had a deeper meaning: this demonstrates that the knowledge they obtain from the course can be applied outside of the classroom, and not necessarily should be boring. Having fun in Science is one of the major themes present throughout Michael’s lectures.

No wonder Michael has this sign on the wall next to his office.

Things to improve. I think that there is one thing that can be improved in Michael teaching: assessment of student learning throughout the lecture. Although Michael posed a lot of questions during his lecture, only a few students participated. Thus, it was not clear whether everyone is keeping up with the material being taught. To go far beyond just asking students “do you get it?”, it is possible to incorporate different activities into the teaching: such as clickers or group discussion.

However, taking into the account the personality of the instructor and his teaching styles I also suggested a more creative way of assessment: hand signals. This technique can be used to rate students’ understanding of content. Students can show anywhere from five fingers to show that they have a maximum understanding to one finger to show that they are struggling with eth materials.

Each of the suggested technique requires a different amount of time and is suitable for different size classes. They also vary in the amount of student-student interactions (see Table below). Thus, depending on the objectives of the course and the time constraints different activity can be chosen. Hand signal provides and instantaneous feedback for the instructor and is suitable for a class of 20 people that Michael is teaching. Student- to student interaction is not crucial during the lectures as the course incorporates weekly group activities for the entire class period at the end of each week.

Student interaction and cognition in online role-playing discussions

Online discussion is a common technique used in face-to-face and distance teaching and learning. However, as students become isolated from peers in online interactions, group learning practices may become less effective than in face-to-face interactions. This paper describes evidence supporting the effectiveness of role-playing discussion for science communication in online education and offers strategies for its implementation. The effectiveness of role-playing discussions was assessed through three measures: 1) student perceptions of the activity, 2) student interaction using the Interaction Analysis Model, and 3) level of cognition using the Revised Bloom’s Taxonomy. The results demonstrated that students were highly engaged in this activity, with limited presence of off topic threads. In addition, students adjusted the cognitive level of their participation as they embodied different roles and performed at high levels of cognition. Role-playing enables rich and adaptable online discussions, facilitating peer learning in distant settings.
