2E1 pupil - Jamie @ workIn the previous practical lesson, the 2E1 pupils had investigated the properties of light as it bounced off the plane mirror by using a ray box. In this particular experiment, pupils would use another method to investigate the image of optical pins in the plane mirror and to trace the corresponding reflected ray to their eyes.

Reflection on the practical lesson
1. Pupils were given time to read through the whole practical experiment and given time to figure out how to perform and take measurements.
2. Due to the new skill of tracing the reflected ray by the placing of the two optical pins, elaborate instructions were given to two separate groups of pupils.
3. Work was assigned to the 2nd group as I explained the details and demonstration the procedures of the experiment. In doing this, the whole class would be engaged in the activity and class work.
4. Demonstration of the procedure would enhance pupils' learning and reduce the likelihood of them being unsure of how to perform the experiment.
5. Pupils who still have difficulties understanding how to perform the experiment and take the measurements were requested to bring their individual sets to the front of the teacher's bench as that extra assistance can be rendered to them while the rest of the class proceeded with the experiment.
6. A video of the placing of the optical pins would enable visual pupils to learn better.
