Development of Integrate Differentiated Learning Modules on Basic Laws of Chemistry Phase E

Abstract

This research aims to produce an integrated differentiated learning module on the basic laws of phase E chemistry that is valid and practical. This type of research is Research and Development (R&D) with a four-D (4D) development model which consists of four stages; (1) define, design, develop, disseminate. This research is limited to the development stage of validity testing and practicality testing. The validity test was carried out by 5 validators and the practicality test by 2 teachers at SMAN 4 Pariaman and 35 class X students. The research instrument used was a validity and practicality questionnaire which was analyzed using Aiken's V formula. Data analysis obtained an average validity of 0, 9 with valid categories. Based on the practicality test of teachers and students respectively, percentages of 0.9 and 0.94 were obtained in the very practical category. Based on the research results, it can be concluded that the integrated differentiated learning module on the basic laws of phase E chemistry is valid and practical.
