Abstract

This study aims to determine the ability of mathematical representation of students in geometry material after learning with the help of GeoGebra. This research is motivated by students' difficulty in interpreting geometric shapes. This research is qualitative research with a descriptive approach. The subjects in this study were 3 (three) class XII students who had obtained three-dimensional material with the help of GeoGebra applications. Researchers carry out the data collection process by providing mathematical representation ability test questions, conducting interviews, and taking documentation. The data obtained in this study were analyzed using specialized triangulation-checking techniques. Based on the results of data analysis and the effects of interviews with all research subjects, it can be concluded that learning geometry with the help of GeoGebra applications can improve mathematical representation capabilities. Three mathematical representation abilities, namely visual representation, equation or expression, and written words or texts, are possessed by students after learning geometry with the help of GeoGebra applications.

Abstract

This study aims to determine the psychological condition of students in learning mathematics. The psychological condition of students is important to know as a guide in preparing lesson plans. This research is a descriptive research with a quantitative approach. This study describes the results of the psychological analysis of SMA Negeri 1 Beber students which include: emotions, self-confidence, interest, and motivation. The subjects of this study were 30 students of Class XII IPS SMA Negeri 1 Beber. Based on the analysis of the results of the psychological questionnaire, it can be concluded that students' readiness in learning mathematics from the psychological aspect reaches 66% or is in the moderate category. The application of group study to the mathematics learning process can be used as an option by the teacher to be able to increase students' interest in learning. Giving project-based assignments can be given to reduce student boredom in working on math problems and to increase student experience in the learning process.
