Abstract

In learning mathematics, representation and communication ability are required by students to solve problems. The ability to represent is crucial for students to simplify the learning process, while students who have good mathematical communication abilities can easily solve a problem. This study applied a sequential mixed methods approach. Quantitative data was obtained from the results of the written test, then the ability of mathematical representation and communication in solving problems on linear program material was analyzed qualitatively. The participants of this study were 59 students from one of the senior high schools in Ambon, Indonesia. The research phase was begun with students being asked to solve mathematics problems and then researchers analyze representation and written communication ability. The largest percentage of students' results on the test was in the very low category of mathematical representation and communication ability. The results showed that students who had good representation and communication abilities would be able to solve problems. There were significant correlations and a very strong correlation between mathematical representation and communication ability with a Pearson Correlation coefficient of 0.915. After obtaining the test result, subjects were selected based on the category of ability to conduct interviews. Based on the results of the interview, the mathematical representation ability that the subject uses well will directly involve mathematical communication skills well, and vice versa.

Abstract

The implementation of this community service aims to help teachers use technology as a learning medium during Face-to-Face Learning (PTM) and Distance Learning (PJJ) activities at junior high schools in Ambon City, where problems that often occur are related to improving teacher pedagogic competence. The object of this activity is all junior high school teachers of mathematics subjects in Ambon City. The learning process not only provides information from teachers to students, but learning must be prepared properly, one of which is through the provision of interesting learning media and by the times. Technology-based learning media solutions that can be used in the industrial era 4.0 are Geogebra Software and Swish Max, so that achievements in the learning implementation process can be obtained optimally. This training activity through community service (PkM) provides space for teachers to innovate in developing the quality of learning through the development of appropriate learning media
