Abstract

The purpose of this research is to identify the learning obstacles experienced by students at Nurul Huda Jannatun Vocational High School. This study is a qualitative research that uses the Didactical Design Research (DDR) model. The population of the study consists of 32 students from the 11th grade of Nurul Huda Jannatun Vocational High School, while the sample is taken from 3 students using purposive sampling method. The research findings reveal the following student obstacles: lack of readiness to receive learning due to a lack of motivation in learning, lack of knowledge of formulas to solve problems, misinterpretation of problems leading to errors in calculations, lack of understanding of the concepts presented in the given problems, inability to answer questions involving two transformation concepts, inability to answer story problems, perception of teachers explaining the material too quickly and lacking easily understandable illustrations, and inadequate teaching materials that do not explain the material in detail for each part

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.
