ANALYSIS OF STUDENTS’ ANSWER ABOUT THE CONSERVATION OF MECHANICAL ENERGY CONCEPT IN PHYSICS EDUCATION BENGKULU UNIVERSITY

Abstract

Purpose of study: This research aims to analyze students' answers about the conservation of mechanical energy assessment in the form of essay tests. Methodology: Descriptive quantitative methods chosen by the researchers involving 46 students of physics education in physics education at Bengkulu University. Students are asked to answer tests on the conservation of mechanical energy consisting of 5 essay questions, which involve verbal, mathematical, and picture representations. Interviews will also be conducted to ascertain student answers. Main findings: This research found that 38% of students answered correctly and others still answered incorrectly because they asked for difficulties in mastering the concepts of physics. Applications of this study: The implication of this research is to help students improve their conceptual understanding, so students can solve problems about physics correctly. The novelty of this study: The researcher explains about what is important in building students' conceptions in-depth and directing students to solve problems about physics, especially about the conservation of mechanical energy.
