Abstract

Conceptual understanding is often a problem in science learning, and this issue has become the point of science education experts, including in Indonesia. Lately, ten articles in Indonesia and six articles in other countries have discussed the model of the 7E Learning Cycle. It was mentioned that this model is able to increase learners’ conceptual understanding. This research intended to reveal the effectivity of physics learning using the 7E Learning Cycle in improving students’ understanding of temperature and heat concepts. The research design is quasi-experimental with a non-equivalent control group design. The sample was senior high school students. Objective test in the form of multiple choices equipped with reason was employed as the data collection instrument. Based on the data analysis, the value of Effect Size was 0.5 and belonged to the medium category. In other words, the use of the 7E Learning Cycle model is sufficient to improve the learners’ understanding of temperature and heat concepts. This could be seen from the success of the learning process that integrates the whole seven stages with the seven indicators of conceptual understanding in detail. Thus, the 7E Learning Cycle could be effectively applied and can increase the students’ conceptual understanding.

Abstract

This study is set in the context of teaching and learning about electromagnetism in Greek high schools. Drawing from constructivism theory, the study aspires to explore students’ understandings of key concepts on both electric and magnetic field as well as electromagnetic induction. For this purpose, an experimental investigation was conducted with 80 11nth grade high school students. Empirical data was collected through a questionnaire which was developed on the basis of test subjects used on past exams in Greek high schools in electromagnetism area. Research findings suggest that students face difficulties in dealing with qualitative tasks in electric and magnetic field. In addition, they seem to confront severe difficulties in conceptualizing the notion of induction of emf.
