Development of an E-module Chemistry Based Discovery Learning in Oriented Chemoentrepreneurship Buffer Solution Material for class XI SMA/MA

Abstract

This research was conducted to develop teaching materials in the form of e-learning. E-modules that relate chemistry to everyday life. The purpose of this study is to develop an e-module based on the discovery learning oriented chemoentrepreneurship in a valid and practical class XI SMA/MA buffer solution material. This research is development research with a 4D development model. The 4D development model consists of 4 research stages, namely (1) define, (2) design, (3) develop, and (4) disseminate. The e-module validity test was carried out by three Chemistry lecturers, FMIPA UNP, four chemistry teachers, and 4 lecturers in Informatics Engineering, FT UNP. The practicality test was carried out by 2 chemistry teachers, and 32 class XII students of SMA Negeri 5 Solok Selatan in the 2021/2022 school. Data processing was obtained by distributing validity questionnaires and the e-module was generated by analyzing using the formula Aiken V data from the practicality questionnaire using descriptive statistical percentages. From the results of the research conducted, the results of the validity test of material experts and media experts were 0.90 and 0.93 with valid categories. While the results of the practicality test of e-modules by teachers and students are 94,6% and 89,6% with very practical categories. Based on the results of these studies, it can be concluded that the development of the discovery of learning-oriented chemoentrepreneurship on the material of the XI SMA/MA class XI buffer solution is valid and practical.
