Abstract

This study aims to determine the feasibility of developing case-based food microbiology textbooks based on assessments from subject matter, educational technology, and language experts. Knowing the response of lecturers and students and knowing the effectiveness of textbooks in terms of critical thinking skills. Materials and Methods: Textbook development using the ADDIE design model. The population in this study were all fifth semester students of the Biology Study Program, Universitas Negeri Medan. The sample for this study was 50 students. Data collection instruments used werre questionnaires, test and interviews. Data analysis techniques use quantitative and qualitative data. Qualitative data were obtained from the results of the needs questionnaire, while quantitative data were obtained from textbook feasibility assessment scores given by material, learning technology, and language experts, responses from lecturers and students, as well as product effectiveness test results. The results showed that the material validation experts were in the feasible criteria (91%), the linguists validation was in the very feasible criteria (88%) and learning technology experts validation was in the very feasible criteria (83%). The results of the lecturers responses were in very good criteria (84%) and the results of student responses were in very good criteria (88%).
