Predict, Plan, Observe, Explain and Write (PPOEW): A Strategy to Prevent Students’ Misconceptions On Work and Energy Topics

Abstract

This research based on students’ misconceptions on work and energy topics. Students’ misconceptions could be prevented through Predict, Plan, Observe, Explain and Write (PPOEW) strategy on their learning. This research methodology was conducted in a quasi-experimental design with control group of pre-test and post-test for 18 students consist of 13 girls and 5 boys as research subjects and 37 students as control subject. The four-tier test used as an instrument to identified student’s misconception on Work and Energy topics that has been developed in previous research. The data analysis focused on how effective was the PPOEW with computer simulation to reduce students’ misconception in the concept of positive energy, negative energy, conservative and non-conservative energy, work-kinetic energy theorem, and energy conservation law. According to the result of the research, PPOEW reduces students’ misconception from 52% to 14%. In addition, PPOEW also increased student’s concept shown by an N-gain value that about 0,5 (medium).
