Teacher Knowledge of Biological Evolution from the Perspectives of Classical Test and Item Response Theory.
Lee, Yew Jin; Izard, John; Yeoh, Oon Chye
Whether poor knowledge of evolution among Singapore students might be linked to low levels of content knowledge about evolution among junior high school and senior high school teachers was studied. A teacher questionnaire on biological evolution was developed. Twelve teachers from Singapore junior college (JC) schools and 42 from the lower secondary schools completed the survey, which was judged to have acceptable reliability. Classical item analyses and Rasch item analyses were performed. Both JC and lower secondary teachers had a reasonably good grasp of the subject matter in evolution and ecology, with JC teachers having significantly better understanding of evolution than that of lower-level teachers. Even though teachers displayed a fairly good understanding of the subject matter, there were some alternative conceptions observed, especially among secondary teachers. Avoidance of some of these alternative conceptions should be emphasized in teacher training. (Contains 4 tables and 24 references.) (SLD)
