Quantitative and Qualitative Analysis of Pre-service Physics Teachers’
Understanding of the Concept of Force before and after an Inquiry-based Physics Experiment Course
Hong-jeong Kim · Sungmin Im ∗
Department of Physics Education, Daegu University, Gyeongsan 712-714 (Received 15 November 2010 : accepted 17 January 2011)
Students’ preconception has been known to be a very important factor in learning science, but it has been reported that students’ misconceptions can hardly be changed after conventional in- struction independent of their backgrounds and characteristics. In this research, we investigated the change in pre-service physics teachers’ understanding of the concept of force before and after an inquiry-based physics experiment course including socratic dialogue and small group discussion.
For this, we adapted the Force Concept Inventory to measure the change in the understanding for a year-long experiment courses and we analyzed the result quantitatively by using the ratio of correct
-26-
answers, the normalized gain factors(G-factor), and the concentration factors(C-factor), as well as qualitatively by using systematic networks based on the distribution of responses. From the quan- titative analysis, we found that pre-service physics teachers’ understanding of the concept of force was improved, and from the qualitative analysis, we identified that ‘impetus dissipation’ and ‘only activity agents exert forces’ were continuing misconceptions although there had been much positive change in conceptual understanding. This study can infer that such quantitative and qualitative analyses can be utilized as analysis tools in further studies investigating students’ conceptions in learning physics.
