VALIDITAS LKPD ELEKTRONIK BERORIENTASI STARTER EXPERIMENT APPROACH PADA MATERI LAJU REAKSI
This study aims to generate and determine the validity of electronic LKPD teaching materials oriented to the Starter Experiment Approach (SEA) 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 test 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 electronic LKPD oriented Starter Experiment Approach (SEA) on the reaction rate material by material experts obtained a percentage of 73.96% with a valid validity level and media validation by media experts obtained a percentage of 96.78% with a very high level of validity. valid. The overall average is obtained by a percentage of 85.37% with a "very valid" level of validity. Based on the results of the study, it can be concluded that the electronic LKPD oriented Starter Experiment Approach (SEA) on the reaction rate material is very valid to be used as teaching materials for electronic chemistry.
