Effort To Improve Student Achievement In Learning Through The Development Of Function Composition Method Of Discussion On The Approach To Contextual Teaching And Learning (CTL) In Class XI IPA 1 Salatiga Christian Senior High School 1

Abstract

Learning mathematics in class XI IPA 1 Salatiga Christian Senior High School 1 needs to be improved because teachers are still learning that involves using the lecture method and mechanistic approach. Models of learning causes students to be passive in the learning process and do not understand the concept of the material being taught. As a result, many students lack an understanding of mathematical concepts in depth so that the average value achieved was still below the value of KKM is 70 and still below the overall limit of 75%, i.e. 54%. To improve student learning outcomes, improvements are needed learning math is to use the Contextual Learning Teaching approach for developing methods of discussion in learning about the composition of functions. The purpose of this research is to improve student learning outcomes through this method, especially the composition of functions. This type of research is Action Research Class consisting of 2 cycles. The results of Cycle 1 is the average value reached 73.2 and 77.4% achieved a complete limit cycle and the second is the average value reached 81.6 and 93.5% reached the limit to prove that a complete discussion on the method of approach, CTL can Improving student outcomes and activities.
