Kesulitan Siswa SMA Dalam Menyelesaikan Soal Cerita Matematika Materi Peluang

Abstract

Mathematics story problems are math problems that are arranged in relation to the reality that exists in the student's environment which are useful for training students to see the relationship of mathematics to their lives and increasing their understanding of a mathematical concept. Regarding this, in learning mathematics there are still many students who have difficulty in solving story problems. This study aims to describe the difficulties of class XI IPA 2 students at SMA Negeri 8 Medan in solving story problems on the subject of opportunity. This type of research is descriptive qualitative research. Data collection techniques in this study were tests and interviews. The difficulties experienced by students are analyzed based on the objects of study or basic mathematical objects (facts, concepts, operations, and principles). From the results of data analysis, the difficulties experienced by students in solving the story of opportunity problems, namely: 1) Difficulty in facts, students were wrong in making a settlement plan possible because of errors in interpreting the meaning of the question, 2) Concept difficulties, students could not distinguish the use of formulas. combinations and permutations, 3) procedural difficulties, students still have difficulty in working on factorial number arithmetic operations, 4) principle difficulties, students still have difficulties in using existing principles such as "crossing out rules" in the form of factorial number division. The factors that cause students' difficulties in solving story problems of opportunity, among others, are due to mastery of concepts that are not yet good, lack of practice in working on problems, and lack of student interest in learning mathematics
