Pengembangan Lembar Kegiatan Siswa Berbasis Online Berbantuan Geogebra Book untuk Siswa SMA Kelas X pada Materi Trigonometri

Abstract

The implementation of distance learning can not be separated from various problems, including students who are lack of motivation, teachers who find difficulties to work together with parents, and teachers who find difficulties to develop ideas on technology-based learning. To overcome these problems, the student activity sheet which equipped with practice questions and assessments with Geogebra Book aid is already developed as a learning innovation. The material developed in this research is trigonometry with the sub material of graph of trigonometric functions. The research model which used is ADDIE (Analysis, Design, Development, Implement, Evaluate). The research was conducted in SMA Negeri 1 Kepanjen by involving 10 students of social class grade X as test subjects, consisting of 3 students with low ability, 4 students with moderate ability, and 3 students with high ability. Data analysis was measured based on aspects of validity and practicality. Calculation of research data shows that the research product is valid based on an average validity score of 93% and practical based on an average practicality score of 84%. Based on the results of this data analysis, it can be concluded that the product development of student activity sheet along with practice questions and assessments meets the valid and practical criteria to facilitate students and teachers in the process of learning activities.
