Pengembangan Bahan Ajar Ipa Berbasis Ensiklopedia Pada Materi Sifat-Sifat Benda Dan Perubahan Wujud Benda Kelas III Sekolah Dasar

Abstract

Abstract: This research is motivated by the need for teaching materials or a set of learning materials that can help achieve curriculum goals that are structured in a systematic and comprehensive manner so as to create a pleasant learning environment, making it easier for students and teachers in the learning process in the classroom. The purpose of this study is to describe the form of development, the results of the feasibility and practicality of encyclopedia-based science teaching materials on the properties of objects and changes in the form of objects in class III elementary schools. This development method uses the ADDIE model where there are 5 stages in research, namely, Analysis (Analysis), Design (Design), Development (Development), Implementation (Implementation), Evaluation (Evaluation). However, this study did not carry out an evaluation stage and this study stopped at the implementation stage. The data collection instrument used a material expert questionnaire, a teaching material expert questionnaire, a teacher practicality questionnaire and a student response questionnaire. The validation results show the percentage of material experts is 85.29%, with the "feasible" category, media experts a percentage of 90.39% with the "feasible" category, and the teacher practicality response questionnaire percentage of 94.44% with the "very good" category, and student response questionnaire percentage of 93.25% with the category "very good". Research on the development of encyclopedia-based science teaching materials is categorized as "Very Appropriate" or "Very Good" for use in the field. This encyclopedia-based science teaching material can be used by teachers as teaching materials in learning, helping students to learn independently or with teacher guidance, and providing references for other researchers in developing teaching materials in innovative learning.
