![]() 2 While Surya (2011) state that representation is a model or substitution of a problem to find the solving. 1 Representation is one of higher order thinking ability aspects, the most important and fundamental component in developing students’ thinking ability because in learning math, students are required to connect what they are learning and interpret the idea/concepts into various features.Īccording to Fadillah (Nursangaji, 2013), "representation is expressions of mathematical ideas presented by students as models or representatives in a math problem which are used problem solving they have as a result of students’ thinking interpretation". Hasratuddin (2015) proposes that students’ mathematic representation ability becomes one of students’ ability that needs to be concerned because it allows and helps students insolving math problems, transforming an abstract concept into concrete one, such as pictures, symbols, words, graphics, tables, etc. 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. The data of the study is analyzed by using two ways variance analysis. The instruments used include: (1) test of representation ability, and (2) self-efficacy questionnaire. ![]() ![]() ![]() 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. ![]()
