Artun, Huseyin; Costu, Bayram – Journal of Science Education and Technology, 2013
The aim of this study was to explore a group of prospective primary teachers' conceptual understanding of diffusion and osmosis as they implemented a 5E constructivist model and related materials in a science methods course. Fifty prospective primary teachers' ideas were elicited using a pre- and post-test and delayed post-test survey consisting…

Costu, Bayram; Ayas, Alipasa; Niaz, Mansoor – Chemistry Education Research and Practice, 2010
We constructed the PDEODE (Predict-Discuss-Explain-Observe-Discuss-Explain) teaching strategy, a variant of the classical POE (Predict-Observe-Explain) activity, to promote conceptual change, and investigated its effectiveness on student understanding of the evaporation concept. The sample consisted of 52 first year students in a primary science…

Investigating the Effectiveness of a Constructivist-Based Teaching Model on Student Understanding of the Dissolution of Gases in Liquids
Peer reviewed Peer reviewed
Direct linkDirect link
Calik, Muammer; Ayas, Alipasa; Coll, Richard K.; Unal, Suat; Costu, Bayram – Journal of Science Education and Technology, 2007
The research presented in this paper consisted of an investigation of the effectiveness of a four-step constructivist-based teaching activity on student understanding of how pressure and temperature influence the dissolution of a gas in a liquid. Some 44 Grade 9 students (18 boys and 26 girls) selected purposively from two school classes in the…
