Collaboration, Virtualisation, Conceptualisation, and Engagement

The interviewee name is Mr. S, a secondary teacher. He teaches Science and Chemistry in international schools abroad. He also taught mathematics in middle school, grade 6 to 10. He has been teaching national and international curriculum, and International Baccalaureate curriculum for the past 15 years. The interview took place in school on Sunday 21st January 2018 at 1pm.

Collaboration

Mr.S presented projects-based learning as an important aspect of his science lessons. It was interesting to hear how he assimilates learning to collaborating with others, solving complex problems, critical thinking, developing different form of communication, and improving motivation. He uses technology every day in his classes, through online resources, apps, and Google to enhance collaboration. He finds that Google in particular makes everything easier, because everything is connected – multiple people can edit on one document, Google Classroom can be used to post and collect assignments, notes can be taken much more quickly and shared. He uses technology to help his students developing practical skills such as creating presentations, learning to differentiate reliable from unreliable source on information, and writing emails. In his opinion, these are very important skills that can be developed in any classroom and that enhance collaboration. Mr.S does a lot of group projects in his lessons; he presented collaboration as essential to effectively and efficiently complete any assigned task. He uses technology to transform the learning experience providing his students with the opportunity to enhance the interaction with their peers.

Virtualisation

Some topics and phenomenon in science are abstract in nature, he said. In such a way that sometimes, detailed descriptions in books or through verbal explanation do not always guaranty a correct understanding of the concept. He finds that students usually fail to make connections with their own life because they developed a faulty mental representation. When technology is available, he uses digital tool to enhance visualisation and make the topic more accessible to the students. He presented ‘molecular structure’ as an example of topic in science where simulation is very useful to visualise in three dimensions how molecules change as reactions occur. Also, he emphasised the importance of simulation for some experiments that cannot be physically conducted because elements are either too tiny or dangerous to be handled. I believes that Virtual reality technology combined with traditional classroom teaching instruction enhance the learning experience and create new opportunities for learning.

Conceptualisation

Mr.S finds that technology in classroom is an effective way to connect with students of all learning styles. Students do not always conceptualise or proceed information the same way. Because some topics in science are abstract in nature, technology has helped Mr.S to make some topics more accessible to students. In fact, he uses technology to give students access to incredible amount of new opportunities that facilitate understanding through simulation in virtual reality. For him, this helps to deepen understanding as the students make authentic connections between the concepts they are learning, their environment, and their life.

Engagement

When technology is integrated into his lessons, Mr.S finds that students are more interested in what they study. Technology provides him different opportunities to make learning more fun and enjoyable in terms of teaching same things in new ways. For instance, Mr.S believes that teaching through gamification, competition, taking students on virtual trips and using other online resources encourage more active participation in the learning process. Which that can be hard to achieve through a traditional lecture environment.  When the students are engaged and interested in things they are studying, it increases their knowledge retention.

Video cases analysis

The videos show the importance of technology in exploring preconceived ideas and background knowledge. They point out that technology can enhance inquiry, critical, and creative thinking skills. Students gain problem-solving skills while exploring different theories and strategies with technology. This exploration helps to reinforce their understanding and it facilitates their decision-making abilities.

In general, technology-based activities or projects are multi-disciplinary and often require that students synthesize their knowledge and understanding. Because it is rare to see teachers who are experts in the use of technology in a multi-disciplinary way, students do not always receive support with this need to synthesize. It is also unusual to see teachers who have a deep understanding of how to effectively use technology within their own discipline or subject area.

We need teachers with deep disciplinary and technology understandings to guide and extend students’ intellectual and practical forays, helping them to improve their inquiry, creative and critical thinking skills through engagement in authentic tasks with clear, precise, and measurable learning outcomes.  We need teachers who can make the best use of technology in the classroom by developing their awareness of range of digital technologies and by considering carefully both how and why technology can be used to support students’ learning. Effective selection of software and devices is only part of the story. Identifying learning outcomes and deciding how technology may help is fundamental in deciding its effective deployment.

The videos also show that technology has not always been reliable. Things do not always work as predicted (e.g. a program will not run on a computer because an installed application is preventing to do so). Therefore, a learning experience could be transformed in a troubleshooting session. Although troubleshooting can be time consuming, both teachers and students can learn technical tricks that can be used in the future.

It is important to be flexible when using technology and explore other technology solutions. Being open to use different technology helps to develop the necessary awareness of the range of technology that can be useful for a particular learning experience.

Time has also been presented as a scarce factor in teaching. Indeed, time is a rare commodity in schools, and any new tip or initiative that squanders it and does not add real value to a teacher’s working day will inevitably fail. That is because the first priority for all teachers is to teach and to improve the prospects of the students they teach. We usually don’t have enough time to explore all aspects of the learning skills that we are teaching. However, teaching strategies such as flipped classroom and blended learning contribute to maximising instruction time.

Technology in teaching and learning

Some aspects of mathematics and science are abstracts. Also, sometimes concepts taught are all new in terms of the contents elaborated. With this regard technology should aim to make instruction more accessible and interesting. Students learn better when they are interested, so technology is the best way to start as they all like technology based applications.

In general, students stay engaged in their learning when their ability to learn is continuously challenged with activities that contain rich experiences and authentic tasks; which that provide students with opportunities to extend their intellect, helping them to extend their way of thinking and what they know as they develop disciplined ways of thinking and encounter others’ ideas. Digital technology gives us tools to create such learning environment that promotes students’ interest and help them to create things that mattered to them.

In mathematics and science, digital technology can help visualizing, simulating, and facilitating analysis and interpretation of data. This will address many conceptual challenges. There are many technologies that we can use to improve teaching and learning in math and science.  However, there are topics in math such as Complex numbers and Calculus where it is challenging to use technology to shift from algebraic manipulation to conceptualization and interpretation of our results.

Using technology to master a particular skill helps to address conceptual challenge. However, technology is not helpful for all learning skills. For instance, though the graphic calculators (GC) are very important to understand functions and algebraic equations. The data processing stage (algebraic manipulation) while solving a problem should not be neglected. The students should know how to process data before they learned to compute it their calculator. Knowledge over data processing is what helps the students to grasp the underlying patterns and principles which drive the production of graphs or results generate by the GC.

Clearing misconceptions with Graphic Displayed Calculator

In general, our minds need to contextualise or conceptualise the information it receives in order to proceed them for understanding. In the video, ‘A private universe’ I will argue that Heather who has little training about astronomy used the information she had to create a mental representation to help her understand how the weather changes. After a formal lesson on astronomy. The way she conceives the weather changes has improved as she was able to replace some wrong mental representation she had with the right ones.

In fact, based on their prior knowledge, the students need to conceptualise the instruction given by the teacher in order to understand and retain them. Students’ experiences are different as they all have different cognitive approach to learning mostly depending on how information is presented to them.

Ball (1993) observes that “current proposals for educational improvement are replete with notions of ‘understanding’ and ‘community’ – about building bridges between the experiences of the child and the knowledge of the expert” (p. 374). She then inquires,

How do I create experiences for my students that connect with what they now know and care about but that also transcend the present? How do I do value their interest and also connect them to ideas and traditions growing out of centuries of mathematics exploration and invention? (p. 375).  (Paul Cobb, Where Is the Mind? Constructivist and Sociocultural Perspectives on Mathematical Development, p 14).

I believe we should give time to our students to cognitively process the information they receive. Also, technology is a good mean to help the students to mentally represent their knowledge. In mathematics, my students usually struggle to represent the phase shits of a sinusoidal functions on a graph.  Their misconceptions are generally cleared out with the use of math software such as Geogebra and Demos, where we can visualize dynamic graphs. Also, graphic display calculators (GDC) is a great tool to make mathematics accessible to the students. When I was in high school we were not allow to use GDC to represent and interpret function, and solve algebraic equation. I used to be confused with function transformations. In math and science, collecting and processing data should be done with fastidious care, in order to avoid errors while solving problems. This stage in problems solving can take quite lots of time while we still need to analyze and interpret our results. GDC helps a lot in reducing the time spend on collecting and processing data and provide good opportunity for analyses and interpretation.

Technological environment helps to develop good understanding of concepts taught in math and science. The challenge remains to find activities rich in skills and experiences to help the students develop their own cognitive approach.

Tetris

I have played quite a lot of video game in my childhood. One which is memorable, it is a tile-matching puzzle game called “Tetris”. I got my first handheld Tetris game in 1990.

I don’t remember being a fan of puzzle by then. However, when I started playing this game. I loved the rewards in the form of bonus points and the destruction’s special effects when a set of tiles were well organized. Every time I was playing this game, I always felt that I was becoming a better player. Once I reached a level in the game, the next time I will reach the same level or end on a level above. What fascinated me most in this game was my ability to see how I was becoming skilful. I played the tetris game till I reached the point where nine times out of ten, I will complete all the levels of the game. This is when I stopped playing. I was just doing it occasionally mostly when I wanted to show off.

By reflecting on this experience, I wish I could create a Calculus game that will have the same effect on my students.

Hi from Bangladesh

Hello everyone,

I teach abroad in international schools. I am currently in Dhaka in Bangladesh where I teach mathematics in secondary school at international school Dhaka. As an educator, I am witnessing substantial changes into education due to technology integration. I hope to learn lots of technology tricks that I can share and use to improve my teaching and learning strategies. I am thoroughly enjoying the MET’s journey. I am taking two courses this term, and fingers crossed I will handle the workload.

When I am not busy teaching, planning, and marking. I love travelling and venturing in green spaces.

I look forward to collaborating and working with you all.

Happy New Year!
