The aim of this study is to improve the mathematical connection capacity of SMAN 13 Garut students in trigonometry materials that have been done by the teacher from cycle by cycle with deductive approach. This research makes up by a classroom Action Research conducted in 3 cycles. Each cycle consists of 4 stages, The subjects were the students of class X IPA 6 in the academic year 2018/2019 where the researcher was a Math teacher in the class. The data research was obtained through observation, questionnaires, and tests. The analysis of data technique is a comparative descriptive. The result of the test concluded that the implementation of class actions through a deductive approach in material for trigonometry can increase learning motivation and connection skills mathematics students. This is based on the results of tests and observation of students- learning motivation there is an increase in motivation to learn mathematics from the former low to quite high. it is suggested to the teacher to be able to apply the learning model with a deductive approach to learning in his class.
