Lenses
We've conducted the written post-test of 5 items and are analysing the results. A perception survey of the attitudes of the students towards the two learning methods has been conducted in the computer lab using the online assessment feature in our Learning Management System (LMS).

We've designed an action research project to help us to familiarise with the AR process.
1. A group of students would learn the topic "lenses" (under Light) using an interactive IT-based lesson module (downloaded from MOE http://www.moe.gov.sg/edsoftware/ir/physics.htm and installed in computer lab) while another equivalent group would have normal classroom lessons. Written worksheets were given to both groups for ray-diagram practice.
2. A post-test of 5 items (mcq with reasoning required) would be conducted after the lessons to evaluate the learning effect.
3. A perception survey would also be conducted to find out the attitudes of the students towards the two learning methods.
