Communication skills focus on the importance of speaking, writing, describing and explaining mathematical concepts. In achieving that success is by using cooperative learning model. This model is an effective teaching strategy in improving student achievement and socialization while contributed to their changing of attitudes and perceptions of the importance of learning and cooperation, including for their understanding of their peers from different ethnic backgrounds. This research was conducted at SD IT Faza Azkia Kelurahan Hutaraja, South Tapanuli Regency, North Sumatera Province. This research uses quasi experimental research method. This study aims to describe how to improve students 'mathematical communication skills before and after using cooperative learning model, and also to know the effectiveness of using cooperative learning model in improving students' mathematical communication ability. Based on the results of the study concluded there is an increase in the mathematical communication skills of students before and after using cooperative learning model. And the cooperative learning model is effective for teaching count number operations. This is shown by: the effectiveness of student learning activities, the ability of teachers in managing learning is effective, students 'responses to learning is positive and mastery of students' mathematical communication skills reach 100%.

PENGARUH METODE INKUIRI TERHADAP HASIL BELAJAR MATEMATIKA SISWA PADA MATERI POKOK EKSPONEN DI KELAS X SMA N 1 BATANG TORU Fitriani Fitriani

Abstract The background of this research problem is that there are student who are not able to use the properties of exponents and are not able to solve the problems exponent while teaching method used is a meaningful method is the method of inquiry (discovery). The main issues discussed in this study is there any influence on the results of the use of inquiry method of learning mathematics students in the subject matter exponent in class X SMA Negeri 1 Batang Toru. This study aims to explain extent of the influence of the methods of inquiry the math learning outcomes of students in the subject matter exponent in class X SMA Negeri 1 Batang Toru. Calculation of the two variables obtained by the average value of the variable X (inquiry method) is 43.77 are "enough" while the variable Y (the results of students' mathematics learning in the subject matter exponent) ie 14.81 are "enough". Based on the calculations in mind that r calculated at 0.7932 then thitung 8.4406 and 2.0189 ttable turns thitung ttabel, then the hypothesis is accepted / approved, so it can be concluded that a significant difference between the use of methods of inquiry to the results of students' mathematics learning in the subject matter exponent in class X SMA Negeri 1 Batang Toru with the category of "strong". KeywordsEffects, Methods of Inquiry, Mathematics Learning Outcomes.

Abstract. This research was conducted at University of Muhammadiyah South Tapanuli in semester VI student of mathematics education program that follow Real Analytical course. This study aims to determine students' mathematical reasoning ability after using constructivism approach and also want to know the effectiveness of constructivism approach to mathematical reasoning ability, as well as expected to give benefit to lecturer of Real Analysis course lecturer. The method used to achieve the goal is by experimental method with pre-experimental design research design. This research produces: A very effective constructivism approach is used to teach real analysis courses. There is an increase in students' mathematical reasoning abilities after using constructivism approach.Keywords: Constructivism, Mathematical Reasoning, Real Analysis.
