Abstract

Mathematical representation is one of the mathematical higher order thinking skills, as a tool or way of thinking in communicating mathematical ideas. Referring to a research about the inconsistency of a mathematical communication profile involving gender differences and the phenomenon of more female students than men right now, there appears to be an allegation that there is a connection between gender differences and students mathematical representation. The purpose of this study is to analyze the improvement of students mathematical representation capability in terms of gender differences. Subjects in this research were students of class X of High School in Medan, Indonesia, consisting of 13 men and 19 women. The research instrument is a mathematical representation test consisting of 4 questions. Data analysis to find out how the category of improvement of students’ mathematical representation, using index of N-gain. The results of the research are: (1) the improvement of mathematical representation ability in the lower and middle categories of male students is higher than female students, (2) there is no male students have high category mathematical representation, but there are female students have high category mathematical representation abilities, and (3) the ability of representation to make mathematical models and explain the verbal language of male students is higher than female students. While the representational ability of making tables and drawing female students is higher than male students. The implication of the research is needs to do deeper research to see the relationship of mathematical representation ability with the students mathematical ability profile.

Abstract

Abstract. This class room action research aimed to improve students mathematical creativity in mathematical problem solving, and described the learning process of students of SMP Negeri 5 Terbuka. The learning method used module learning cycle models. This research was conducted in two cycles included the steps of planning, implementation of action, observation, and reflection. Students mathematical creativity in solving mathematical problems measured was fluency, flexibility, elaboration, and originality. The results showed that students mathematical creativity in mathematical problem solving increased. The aspects of the students mathematical creativity in mathematical problem solving that most increased in this study were elaboration.Keywords: mathematical creativity, solving mathematical problems, module learning cycle models

Abstract. Mathematical communication is the process of delivering ideas/thoughts mathematics both written and orally. Due to convey the idea of pure mathematics can not be delivered orally without writing, the oral mathematical communication in this research is the class presentation of mathematical communication is conveyed through speech or writing related to the speech. The purpose of this study was to determine the accuracy of mathematical communication profile student teachers in solving mathematical problems in terms of gender differences and differences in mathematical ability. Based on the analysis of data it can be concluded in oral mathematical communication, male students convey information more accurate than female students. Keyword: The accuracy of mathematical communication, student teachers
