Abstract

Mathematical problem solving in the form of word problems is very helpful in dailystudent life because this problems always related to daily life. Problems encountered in this research, it was found that the students are less capable in solving word problems. This matter because students had not been given exercises in the form of word problems. To improve the students ability in solving word problems, researcherapply Indonesian Realistic Mathematics Education Approach (PMRI). This research aims to determine that the application PMRI approach can enhance the students' ability in solving word problems and find out how the application PMRI in mathematic. This research is a classroom action research (CAR) conducted in SMP UTY, the Christian school located in t Medan. Based on the research results obtained, it is known that the application PMRI approach can enhance the students ability in solving word problems, although indicators of success has not been achieved in this study. Keywords: Realistic mathematics education, Ability to solving word problems

Abstract

The achievement of the graduates profile which is the goal of Mathematics Education majors Teachers College UPH is to prepare teacher candidates who have the character, calling, and competence also the graduates can role as a Mathematics teacher know the concept of knowledge. However, in the achievement of the graduates profile has not been satisfactory, because results of learning are low in some mathematics courses, especially in Calculus II course. Based on the problem, major Teachers College do a structured academic activity that is response learning. The research method used is control group posttest only design. The sample of the research are the students of Mathematics Education major that take the Calculus II course in the academic year 2015/2016 as the control group and who take the Calculus II course in the academic year 2016/2017 as the experimental group. The improvement of this reponse learning result is seen from t-test analysis, obtained the decision of hypothesis test is exist significant difference between the control class and the experimental class. Keywords : response, calculus II, learning result
