The team met Dr Yap on 15 Feb. He reviewed our current project results analysis and gave us useful insights into inquiry based learning and the action research methology.
Some learning points are:

• the duration of the alternative teaching strategy needs to be sufficiently long to have any significant effect
• besides test scores, it is good to have other "measures" such as attitude surveys, analysis of types of responses in the test, etc.
• different modes of representation may be investigated
• have an operational approach for "inquiry"
