The Development of Trigonometry E-Modules For Senior High School Using Differentiated Instruction (DI) Approach

This research aimed to develop trigonometry e-module for senior high schools through Differentiated Instruction (DI) approach based on Moodle. The method used in this research were Research and Development using Plomp model (2013), consisted of the stages of preliminary research, prototyping, and assessment. This research only discussed research results of the first two stages. Preliminary research stage was the analyzing step that included the curriculum, the students' characteristics, and learning materials analyses. The instruments used in this stage were the need analysis sheet, the observation sheet and the interview guidelines. The research subjects in the first stage were the principal, two Year 11 mathematics teachers and five Year 11 mathematics and science students selected randomly. The next stage was prototyping, where the researcher administered the validation sheet to five students. The result of preliminary stages showed that mathematics teachers have already used the curriculum 2013, and both students and teachers needed an interesting learning media. The validation result of the prototyping stages showed that the module developed was valid and practical. The subsequent stage will be testing the module.
