Abstract

This study aims to determine the effect of GeoGebra software on junior high school students' mathematical communication skills. The method used is the quasi-experimental method. This research was conducted at Pasundan Rongga Middle School. With class VIII A as an experimental class with 28 students and class VIII C as a control class with 28 students. This study uses instruments that have been tested and declared valid and reliable. The instrument was adjusted to the indicator of mathematical communication skills with the number of questions tested as many as 5 questions to obtain pretest and posttest data in both the experimental class and the control class. Data testing is done using normalized n-gain formula so that the n-gain data obtained is processed using the SPSS 20 application to perform parametric statistical tests. The results showed that the mathematical communication skills of students who learned using GeoGebra software were better than students who learned without using GeoGebra software.

Abstract

This research was conducted at SMPN 02 Kersamanah VIII. This research is a Posstest-only Control Design in which the researcher only compares the results of the posttest of the experimental class and the control class. The purpose of this study was to determine differences in the ability of students 'mathematical self-concept between classes where learning uses the RME approach and classes that use conventional approaches and strengthen students' self-concepts in the millennial era. This study used 25 experimental and control class students as samples with a duration of research consisting of 8 meetings. Based on the analysis of post-test data and N-Gain shows that there are significant differences in the ability to think logically mathematically where the mathematical self-concept of students whose learning using the RME approach is better than the classroom learning using conventional approaches. This is because the use of the RME approach provides meaningful learning by seeing, searching, and exploring real objects. Where students have more responsibility for learning mathematics, reducing online gaming activities, and the use of gadgets.

Abstract

This research was conducted at Cikancung 01 Middle School on class VIII triangle material. This research uses the "Quasi-Experiment" method with the researcher accepting what is the sample with a random class. The research aims to determine the differences in students' mathematical creative thinking abilities between classes that use contextual learning and classes that use normal approaches. This study was applied to 25 students in both the experimental and control classes as a sample with the duration of the study consisting of 6 meetings. Based on the posttest data analysis shows that there are significant differences in mathematical creative thinking abilities where students' mathematical creative thinking abilities with the use of contextual approaches are better than classes with ordinary approaches to learning. This is because the use of contextual approaches provides meaningful learning by seeing, searching, and exploring objects in real life into mathematics learning.
