The current study aims at: (1) analyzing differences between students’ Mathematics presentation ability by using learningcycle7E and discovery learning based on BatakAngkola culture, (2) analyzing the differences between students’ self-efficacy by using learningcycle7E and discovery learning based on BatakAngkola Culture, (3) finding out whether there is an interaction between the learning model and students’ KAM on the Mathematics representation ability of students, and (4) discovering whether there is interaction between learning model and students KAM on students self-efficacy. The instruments used include: (1) test of representation ability, and (2) self-efficacy questionnaire. The data of the study is analyzed by using two ways variance analysis. The results of the study show that (1)there is difference in Mathematics representation ability of students who learn by using learningcycle7E model and those who learn by using discovery learning based on BatakAngkola Culture, (2) there is difference between self-efficacy of students who learn by using learning cycle 7E model and self-efficacy of students who learn by using discovery learning based on BatakAngkola Culture, (3) interactions exist between learning model and Students’ KAM toward students’ Mathematics representation ability, (4) interaction exist between learning model and Students’ KAM toward student’s self-efficacy.
