THE EFFECT OF LABORATORY ACTIVITIES DESIGNED BASED ON PREDICT- OBSERVE- EXPLAIN (POE) STRATEGY ON PRE-SEVICE SCIENCE TEACHERS’ UNDERSTANDING OF OSMOSIS AND DIFFUSION SUBJECT
Abstract :
The purpose of this study was to investigate the effect of laboratory activities based on “Predict-Observe-Explain (POE)” strategy on pre-service science teachers’ understanding of osmosis and diffusion subject in general biology laboratory. In this study, the sample consisted of 122 pre-service teachers who took the General Biology Laboratory I course at Pamukkale University, Faculty of Education, Department of Science Education. The research was conducted in fall semester of 2008-2009 academic year. Experimental group (N=60) was instructed with POE strategy, while control group (N=62) received verification laboratory approach designed instruction. Results of the analyses showed a significant effect of activities based on POE strategy on preservice science teachers’ conceptual achievements. At the end of the study it was shown that the POE strategy was effective in identifying students` misconceptions and teaching the concept.
