Feasibility Level of Case Method-Based Chemistry Teaching Materials on Solution Material

Abstract

The purpose of this study is to evaluate the feasibility of teaching materials for Chemistry, which are based on the Case Method on Solution Material and were created utilizing the 4-D Method (Define, Design, Develop and Disseminate). The results of the teaching feasibility were determined by two expert validators who were lecturers from the chemistry department, FMIPA, Universitas Negeri Medan. After collecting data using a feasibility questionnaire for teaching materials according to BSNP and then processing the data to obtain feasibility results in the form of percentages on 4 indicators of eligibility for teaching materials. In the content feasibility aspect, the feasibility aspect obtained a percentage of 94.6%, in the presentation feasibility aspect obtained 94.6%, in the language feasibility aspect obtained 96.9%, and in the graphical feasibility aspect, it obtained 93.3% where all these aspects fall into the very feasible category.
