Abstract

This research is motivated by the results of interviews with teachers of mathematics studies at SMA Negeri 6 Kediri. The mathematics material considered difficult for students is trigonometry in class XI. Therefore, these difficulties impact the learning outcomes of class XI at SMA Negeri 6 Kediri. Based on this, the researcher applied discovery learning to improve students' understanding of mathematical concepts. This research is a Classroom Action Research (CAR). The subjects in this study are class XI MIPA 1 with total 34 students. This research took two cycles,using instruments a lesson plans, UKBM, observation sheets, and objective tests of understanding mathematical concepts. The data analysis technique is descriptive quantitative and descriptive qualitative. The study results showed that the implementation of learning in first cycle obtained a value of 90.90%,in second cycle received a discount of 100%. For students understanding of mathematical concepts, there is an increase in terms of classical completeness and the percentage of each indicator. In the first cycle, each indicator of concept understanding obtained an average percentage value of 74.78% with a classical completeness percentage of 47.05% and in the second cycle, each indicator increased the average percentage value to 81.2% with a classical completeness percentage of 82, 35%. Based on the results of this study, it can be concluded that the application of the discovery learning model can improve students' understanding of mathematical concepts.
