Description

The purpose of this research was to study scientific concepts of the student in conservation of mechanical energy both before and after learning through predict-observe-explain (POE) approach. The target group was 34 grade 10 students, Strisuksa School. The Office of Secondary Education District Area 27, Roi-Et, those studied in the second semester, academic of year 2014. The students’ scientific concepts in conservation of mechanical energy had been studied by using pre-test and the results were used as guiding to develop the conservation of mechanical energy lesson plans. The post-test was done soon after the POE finished. The evaluation tool consisting scientific conceptual test, multiple choices combined with short explanation their answer. The collected data were analyzed by interpreting into groups of scientific concepts and then comparing between pre-test and post-test. The findings revealed that student’ scientific concepts in prior learning of the student science could interpret into various categories and the majority of them were diverged from commonly scientific concepts, but the post-test performed that students scientific concepts generally converging to the scientific concepts. It could be concluded that the POE approach supporting the students to gain their understanding in conservation of mechanical energy.
