Lesson Idea SynopsisA co-created virtual lab learning environment was designed with guided discovery worksheets to support the process of sense making of the physics of collisions. Students investigated into the relationship between the variables collaboratively in groups of 2 to 3, and also shared their analysis through short presentations, for other students to critique.

Instructional ObjectivesCandidates should be able to:
1. apply the principle of conservation of momentum to solve simple problems including elastic
and inelastic interactions between two bodies in one dimension.
2. show an understanding that, whilst the momentum of a system is always conserved in
interactions between bodies, some change in kinetic energy usually takes place.
How was the lesson carried out? (Please include level, ICT equipment & resources needed, pedagogy or strategies used, thinking skills taught, if any, duration of lesson, etc)Self-directed learning (SDL)
Ownership of Learning, students set and identify variables to inquiry on, for example, mass (m1 and m2), initial velocity (u1 and u2), type of collisions (perfectly elastic, partially elastic and perfectly inelastic). Learners have to decide type of variables to inquiry, for example, momentum, kinetic energy, relative speed of approach and separation etc.
Management and Monitoring of own Learning, students explore experimental data and make logical arguments and findings.
students formulate questions and generate own inquiries when conducting the virtual experiment guided by the worksheets.
Students use the feedback form to improve their experience in using the virtual lab.
Extension of Own Learning
Apply learning in new contexts is supported by the application worksheet where they conduct a problem based learning scenario of a crash site between a lorry and a car by examining the evidences of skid marks on the road etc.
Learn beyond the curriculum, students are expose to the concept of coefficient of restitution, e and getting a larger schema of the equations of collision taught in university courses.
Collaborative Learning (CoL)
Effective Group Processes, in pairs the students need to negotiate and set common goals to explore in the lab
Individual and Group Accountability of Learning, students learn in pairs, share their findings in short oral presentations, supported by peers evaluation.
The lesson was carried out with year 5 (JC1),
ICT equipments used included Computers, with Java Runtime installed, Ejs open source java applet 1D collision carts Elastic and Inelastic Collision 1mb file copied into the desktop.
Pedagogy is Learner centred learning with technology.
Strategies Teacher as technology, content, pedagogy and knowledge expert (TPCK), facilitating the inquiry learning process, with teacher to facilitate at suitable times.
Thinking skills, Self directed planning of inquiry approach is required for students to collect data, Science Practical Assessment Skill A. Analysis of data skill is also practiced. Evaluation of data and finally Synthesis skill during the proposing and verifying of their hypothesis of the physics principle .
Lesson is 1 hour 40 mins
How did ICT value-add to the learning process? How did the use of ICT change the learning and teaching process?ICT added value because
1. safe inquiry, lesser chance of injury during physics practical as there is no physical objects moving or falling off apparatus etc.
2. easy setup with virtual labs, real life setup is difficult to calibrate the motion sensors, lack of sufficient number of practical sets
3. 1 to 1 exploration of science principle
4. time spent on learning increased, less time spent on debugging the real life data logger setup with connecting wires, faulty sensors, inaccurate data collected, less variables can be varied reliably.
5. support any time ( no restricted to that practical lesson ), any place ( home based lessons is possible)
What were the outcomes? (Benefits to pupils or teachers, re-designing of pedagogy, development of staff, etc)Benefits to students as collected in the feedback forms are
Yes Hands-on learner
Yes Autonomy to try out different situations
Yes Learn better and clearer this way
Yes Instill concepts and understanding through a clear learning process
Yes See physics theory comes to life, make it easier to understand
Yes Expt is interesting
Yes Hands-on is interesting
Yes Good alternative to usual lab
Yes Fun and engaging
Yes More hands-on, better than lecture
Yes Interactivity keeps me awake
Teacher benefit is he is more convinced that he is doing something meaningful to engage his students.
Re-designing of pedagogy is still teach less, learn more (TLLM), make the learners the centre of learning activities.
Development of staff is teachers learn to design learning environments (java applets), design worksheets to implement meaningful ICT lessons.
How did you assess student's learning using ICT? (Examples of work produced, etc)
Students work were captured in the worksheet.
Students interviews indicate the ICT lesson enables them to learn on their own, more engaging than exisitng lecture style of information delivery system.
Students feedback affirmed the physics teachers professional learning community (PLC) effort.
Do you consider the ICT lesson a success? What went well? What would you do differently next time?some selected comments from students:
"More this kind of lesson
More fun activities
It's flawless
Lesson is effective enough
Lesson is well-planned and effective
Lesson was very concise and effective as it is
Less amount of trials should be conducted
Quite effective"
Differently, Students suggested that
"Air-con room keeps us awake and absorb better
A little more challenge worksheet, maybe engage them in the modeling aspects of the physics or improving the worksheet.
Have better graphics
Applet could be more vivid".
What went well?
Teachers going around to help the groups of students make sense of their own inquiry on variables like real scientists.
What would you do differently?
the teachers role is critical to promote the learning and sense making process, the teacher has to go around the groups to facilitate and ask the groups to make their own logical conclusion and hypothesis.
Will you be conducting this lesson again? If so, when will it be? (E.g., Term 3 in 2010; on-going, etc)
Yes, It will be conducted yearly, usually term 1 JC1.
There is a level wide scaling and translation to all JC1 physics classes from 2010.
With this lesson example, it is hoped that all interested will use this virtual lab to impact their schools physics curriculum through technology.
Please feel free to use it for your classroom.
