Developing of simple props using local materials to support natural sciences learning

Abstract

This study aims to describe the validity, practicality, and effectiveness of simple props. The props developed using the model analysis, design, development, implementation, evaluation (ADDIE) were tested on students of class VIII Junior High School in Banjarbaru using One-Group Pretest-Posttest Design. The data in this study were obtained through validation sheets, questionnaires, and learning outcomes tests. The results of this study indicate: 1) the validity of simple props was valid, and the validity of the student worksheet category is very valid, with the results of validation of 3.19 and 3.40. 2) the practicality of simple props was very practical with the results of the questionnaire calculation of 4.38. 3) The effectiveness of simple props was a very effective category of learning outcomes tests with test results gain of 0.71. It was concluded that simple props use local materials to support natural science learning feasible to be used in the learning process in the subject matter of solid pressure and liquid pressure.
