Reflection (Session 2)
Read through Mathematics LE(Castillo,2005) twice and I find this article has a detailed write-up on the modified research instruments; WIHIC and TOMRA. Using both quantitative and qualitative research methods, a pilot-testing involving 20 students were conducted to check the construct validity of the WIHIC and the attitude questionnaires. My understanding is, these 20 students were included in the actual sample of 510. A question came to my mind: Should these 20 students be excluded from the actual study? I better check with my group members to see how they have intepreted it as our group is working on this article.
