Reconstruction of chemistry module in the class XI high school context of equilibrium based on environment discovery learning

Abstrak

The aim of this research is to reconstruct the chemical equilibrium context chemistry module based on Environmental Discovery Learning (EDL) using the Educational Reconstruction (MER) Module stages. Observation results show that class XI Science students at SMA 3 Jayapura have quite good chemistry scores, but they still need to be improved. This research was conducted to determine the feasibility of a chemistry module based on chemical equilibrium (EDL) context which was tested on a limited scale on 15 stude nts to determine the increase in understanding of the concept. The techniques used in collecting data are questionnaires, tests and documentation. The questionnaires used in this research were expert validation questionnaires, teacher responses and student responses. The expert validation questionnaire and response questionnaire used were adapted and adapted to research needs. The expert validation questionnaire was divided into material content validation with a validation expert judgment value of 80.56%, media content validation of 89.89% and language content of 77.27%. The teacher and student response questionnaire used a positive questionnaire. The average percentage of teacher responses was 91.67%, while student responses with an average score of 86.56% showed that teacher and student responses to the module were very positive. The test carried out on students used 30 pre-test and post-test multiple choice questions with N-gain results for 15 students of 0.6, including in the medium category. The overall results o f questionnaires and tests show that the EDL-based chemical equilibrium context chemistry module is very suitable for use with an expert judgment score of  82.24%.
