Abstract

This study aims to generate and determine the validity of LKPD teaching materials based on Predict, Explain, Observe, Explain (PEOE) assisted by PhET Simulation on the reaction rate material. This research is a type of research and development Research and Development (R & D) using the ADDIE development model, namely Analysis, Design, Development, Implementation, and Evaluation. The teaching materials developed were validated by material experts and media experts. The trial subjects of this study amounted to 2 validators. The trial was carried out using the validation sheet method (questionnaire) given to the validator. The method used to analyze the data using descriptive qualitative and quantitative analysis techniques with a score of four scales (Likert scale). The results showed that the validity of the LKPD material based on Predict, Explain, Observe, Explain (PEOE) assisted by PhET Simulation on the reaction rate material by material experts obtained a percentage of 85.5% with a valid validity level and media validation by media experts obtained a percentage of 81, 82% with a very valid level of validity. The overall average percentage obtained is 83.66% with a "very valid" level of validity. Based on the results of the study, it can be concluded that the LKPD Based on Predict, Explain, Observe, Explain (PEOE) assisted by PhET Simulation on the reaction rate material is very valid to be used as teaching material for chemistry learning.
