Abstract

This research and development aimed to develop electronic learning media for teaching trigonometry. The media developed was EDUTRI, an acronym for E-module trigonometry. This research was conducted on students at class XI IPA 1 and XI IPA 2 of SMA Kristen Satya Wacana, consisting of 34 students as research subjects. The research utilized R&D with the ADDIE development model. This model consists of five stages: analysis, design, develop, implement, and evaluate (evaluation). The validity of the product was examined by the experts’ judgement, while the practicality of the e-module media was examined through limited trials using a questionnaire. Then, the product effectiveness was obtained through a one-class trial with a pretest and posttest design. The results were tested using the Paired Samples T Test. The final result of this research was an android-based e-module media for grade X students. Based on the results from media experts and material experts, the android-based learning media was valid with an average score of 98.33%. In addition, the results of the questionnaire from teachers and students found that the media was practical with a score of 98.33%. Finally, the results of the Paired Samples T Test pretest–posttest confirmed that EDUTRI learning media was effective to be used for learning trigonometry, with an average score of 82.4%.
