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

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 application of character learning to elementary mathematics requires certain techniques. In the mathematics of elementary school teachers should use abstract media. Problems that arise in elementary school mathematics teacher in Kecamatan Negeri Katon is lack of knowledge in using props, in this case on FPB material and KPK. In addition, teachers are still confused in choosing the props that should be used on every learning material. To overcome this is used DAKOTA props that can facilitate students' understanding in learning FPB and KPK materials. The method used in this devotion is the making of DAKOTA props using rigid boards. From the results of this devotion activity obtained the spirit of mathematics teachers and the emergence of ideas to make props on other learning materials.
