Development and Implementation of Teaching Aid Guide Based on Discovery Learning Models on Optical Telescope Materials at Lokon St. Nikolaus Tomohon High School

Abstract

Mario Violendt Kojongian. This study aims to produce the development and implementation of teaching aids based on discovery learning models on optical telescope materials. This study refers to the research implementation procedure "Research and Development" developed by Borg and Gall (1989: 784). Research data from media experts shows that 92.5% is in the Very Strong category, and from material experts it is 92.5% in the same category. The empirical test consisted of 10 students in the small group and 28 students in the large group. Analysis using paired sample t-test shows the sig. (2-tailed) of 0.000 <0.05 which means that the development and implementation of teaching aids based on discovery learning models on optical telescope materials is good. Where there is an increase in the average value of students after following the practicum guide. This shows that the learning process using teaching aids based on the discovery learning model on the optical telescope material for Class X SMA Lokon St. Nikolaus can improve student learning outcomes.
