The Development of Research-Based Electronic Teaching Materials on Alternative Energy Source Materials to Improve Science Process Skills of MTs Students

Abstract

Science learning in the digitalization era contains a combination of theory and practice in the process of finding a concept. The use of textbooks in the era of digitalization needs to be developed into teaching materials for supplements that are packaged electronically. The purpose of this study is to determine the effectiveness of research-based electronic teaching materials implemented in Alternative Energy Source materials towards improving the skills of the science process (KPS) of MTs students. Based on the results of the study, the results of the observation of students' science process skills obtained an average score percentage of 88.28% with a breakdown of observing indicators of 90.63% and communicating 85.94%. Meanwhile, the cognitive learning outcomes of students' science process skills were 81.25 with details of each student's science process skill indicators, namely classifying 84.38, interpreting 91.41, formulating hypotheses 76.56, conducting experiments 74.22, and concluding 79.69. The results of the analysis of the N-gain value of 0.70 high criteria. Thus, based on these results, the use of research-based electronic teaching materials on Alternative Energy Sources materials contributes to the improvement of the science process skills of MTs students. Keywords: research, research-based electronic teaching materials, science process skills.
