PENGARUH PENERAPAN METODE CERAMAH DAN DISKUSI TERHADAP PEMAHAMAN KONSEP PADA MATERI IPA ZAT DAN PERUBAHANNYA KELAS 7 SMP

Abstract

This study aims to determine the effect of applying lecture and discussion methods on students' conceptual understanding of matter and its changes in Grade VII science lessons. The background of this study is based on students' low conceptual understanding due to the dominance of one-way lecture methods and minimal interaction. The research used a quantitative approach with a one-shot case study design. Data collection techniques were carried out through questionnaires with a Likert scale and posttests compiled using the Wordwall application. The research subjects consisted of 31 seventh-grade students in Jember Regency. The results showed that the combination of lecture and discussion methods had a positive effect on improving students' conceptual understanding, with an average posttest score of 77.6, which is considered good. Students demonstrated a better understanding of the concepts of matter, types of matter, and physical and chemical changes. The application of these two methods proved to be effective because they were able to balance the systematic delivery of material and active student participation in the learning process. In addition, the use of interactive learning media also increased students' motivation and interest in learning. Using a combination of lecture and discussion methods is an effective learning strategy for improving students' conceptual understanding and critical thinking skills in science learning.
