PENERAPAN STRATEGI PREDICT DISCUSS EXPLAIN OBSERVE DISCUSS EXPLAIN (PDEODE) BERBANTUAN SIMULASI KOMPUTER UNTUK MENGURANGI KUANTITAS MISKONSEPSI DAN MENINGKATKAN KEMAMPUAN MEMAHAMI KONSEP PESERTA DIDIK PADA MATERI MOMENTUM DAN IMPULS

This study aims to identify the effectiveness of implementation Predict Discuss Explain Observe Discuss Explain (PDEODE) assisted by computer simulations to reduce students’ misconceptions and improve students’ conceptual understanding. The research method used in this study is a mixed-method with a sequential explanatory design. The subjects in this study consisted of 22 students (12 females and 10 boys) class X at one of the high schools located in Indramayu. The instrument used in this study was a four-tier test developed with the 3D + 1I model. To reduce students' misconceptions is known by calculating the PKM equation, while to know an increase students conceptual understanding is calculated using N-Gain and its effectiveness is also calculated by effect size. The results showed that the application of PDEODE assisted by computer simulations was able to reduce the number of students' misconceptions on the material of momentum and impulse with a percentage of PKM value of 81%. Then, the level of students' conceptual understanding increases with N-Gain 0.73 and score of effect size is 4.95
