Abstract

This study aims to determine the level of mathematical communication skills and student learning activeness. The method used for analysis in this study is a Descriptive Qualitative Method that aims to be able to analyze the results of students' work on mathematical communication tests and search questionnaires on student learning activeness. The samples studied were 30 students from a total of 34 students of class IX-C at GUNUNGHALU 1 Public Middle School in West Bandung Regency in the 2018/2019 school year. The test questions used were mathematical communication as many as 3 questions as well as non-active learning instruments as many as 18 statements for each student. The results of the analysis obtained are mathematical communication skills and in junior high schools in West Bandung regency based on written description tests are still relatively low, especially on indicators linking diagrams into mathematical ideas, student learning activeness in learning mathematics is mostly not consistently involved in mathematics learning.

Abstract

This study aims to determine the effect of learning with the help of Geogebra on improving the mathematical problem solving abilities of middle school students. The research method used simple linear regression analysis with IBM SPSS 20 and research design with The One-Group Pretest-Postest Design. The place of research was conducted in one of the Cimahi city junior high schools in class VIII even semester 2018-2019. The subject of this study was class VIII B students on circle material. The instrument of this study is a test of the problem of problem solving ability. The results of the study showed that there was a significant positive effect between learning with Geogebra's assistance on the improvement of junior high school students' mathematical problem solving abilities
