Abstract

The research was conducted to determine students' ability to solve problems with matrix material. This study used descriptive qualitative research and took 20 class XI students of SMK Bina Bangsa as research objects. The techniques used to collect research data are 3 instruments in the form of question descriptions and questionnaire forms. Data analysis in this study used data reduction, data presentation, and drawing conclusions. As a result of this study, students of class XI at SMK Bina Bangsa did not do well in mastering the matrix material and understanding the concepts. The reason students find it difficult to master matrix concepts is because students do not have the necessary material such as fraction operations and negative number operations. The lack of practice questions is also a factor in students' lack of understanding of the determinants of matrices.

Abstract

The aim of this research is to explore students' problem solving abilities in understanding trigonometry concepts. This research is qualitative research with a case study method. This research was conducted on class XI students at one of the private vocational schools in Tangerang City, Banten, totaling 35 students. Data obtained from the results of written tests and interviews conducted by researchers. In this study, researchers analyzed students' abilities in answering Trigonometry questions using constant comparative analysis techniques which consisted of four stages, namely data reduction, data categorization, data synthesis, and working hypothesis.
