Abstract The objectives of this research was to solve how to increase the mathematical communication skills of students in mathematical problem solving especially on the subject of Statistic. This study aims to determine whether the students’ mathematical communication skills of students in mathematical problem solving of the student SMP Muhammadiyah 1 Gadingrejo in the academic year of 2014-2015 using learning method mind mapping on the subject of Statistics can be higher than the students’ mathematical communication skills of students in mathematical problem solving without using learning method mind mapping. This research is a quantitative approach, with a quasi-experimental research methods. The population was all of the students in first grade of the SMP Muhammadiyah 1 Gadingrejo in the academic year of 2014-2015. The samples of the research were taken by using the cluster random sampling technique. Based on hypothesis test, it can be included that there are increase the mathematical communication skills of students in mathematical problem solving after using learning method mind mapping on the subject of Statistics of the student in first grade of the SMP Muhammadiyah 1 Gadingrejo in the academic year of 2014-2015. Keywords: learning method mind mapping, mathematical communication skills,mathematical problem solving

Abstract

This study aims to find the average of student learning achievement byimplementing inquiry and expository method on sets material. To determine thedifference between mathematics students learning achievement in the class thatused inquiry method and the class that used expository method are using t test ifthey are fulfill two assumptions they were normal and homogeneous distributions.Based on the data analysis concluded that any mathematics learning achievementaverage differences obtained by inquiry method on the sets material. It showedthat the students taught by inquiry method got better learning achievementaverage than the students taught by expository method.Keywords: inquiry method, expository method, students learning achievment

Abstract

The purpose of this study was to describe the level of students' written mathematical communication skills in solving story problems in algebraic material. The population used is class VIII SMP N 1 Gadingrejo 2017/2018 Academic Year. While the sample is class VIII.9 students with sampling techniques using purposive sampling. The analysis results obtained by students who take the test of written mathematical communication skills there are 11.76% of students who have very low mathematical communication skills, 26.47% of students who have low mathematical communication skills, 38.24% of students who have moderate mathematical communication skills, and 23.53% of students who have high mathematical communication skillsKey Word : Komunikasi matematik, soal cerita, aljabar
