DEVELOPMENT OF LEARNING DEVICES BASED ON CONTEXTUAL TEACHING AND LEARNING MODEL BASED ON THE CONTEXT OF ACEH CULTURAL TO IMPROVE MATHEMATICAL REPRESENTATION AND SELF-EFFICACY ABILITY OF SMAN 1 PEUREULAK STUDENTS

This study aims to: 1) The effectiveness of learning-based learning model of CTL-BKBA; 2) describe the improvement of students mathematical representation and self-efficacy ability based on CTL-BKBA learning model developed learning tools. This research is a development research done in two stages, that is first stage of development of learning device based on CTL-BKBA model by using 4-D development model, and second stage tested learning device based on CTL-BKBA learning model developed in class XI IPA 1 and XI IPA 2 SMAN 1 Peureulak. From the results of trial I and trial II obtained: 1) learning devices based on CTL-BKBA model developed has meet effectical used to improvement mathematical representation and self-efficacy ability of students; 2) there is an increase of students mathematical representation and self-efficacy ability by using learning tool based on CTL-BKBA model.
