Abstract

This research is motivated by the many mistakes made by students in solving problem-solving questions. The purpose of this research was conducted to see the causes of student errors in solving problem-solving questions based on kastolan error analysis theory. The research method used is descriptive qualitative. The instrumented object in this study involved 4 students of class XI MIA 5. The sample selection technique uses purposive sampling. The instruments used in this study were tests and interviews.The test results were obtained from a problem-solving ability test through creative problem-solving learning on linear programming material. Based on the results of the many errors found in the indicator, presenting mathematical situations in various ways and knowing the differences, and developing the concepts that have been studied. The types of errors that students have made in answering the problem included conceptual error, procedural error, and technical error

Abstract

This study observes students' problem-solving abilities in solving non-routine statistic problems. In this paper used descriptive qualitative by considering the population in one of the VIII I grade junior high schools in Bandung, namely SMP 12 Bandung by categorizing the results of problem-solving abilities into two categories, namely high and low. The sampling technique used purposive sampling involving 29 students. This research used problem-solving tests and interview guides to collect data. Test question was describing mathematical problem solving, consisting of one question on the Polya stages, which is used as a tool. This paper presents that students with high problem-solving skills in this study indicate that students with junior high problem-solving skills fall into the "good" category. At the same time, students with not good problem-solving problems, we can call it as "not good" category. The caused was the inability of students in the initial stage of problem-solving indicators, namely the process of understanding problems, usually students have difficulties in understanding and identifying problems, and difficulties in converting abstract tasks into mathematical form.
