Abstract

The purpose of this study was to find out: (1) what types of errors were made by students in solving questions on the fundamental method of counting, (2) what factors caused students to make mistakes in solving questions on the fundamental method of counting. This study used descriptive qualitative method. The subject of this research is the first semester of Informatics Engineering students. Data collection using test and interview methods. Data analysis techniques include the stages of data reduction, data presentation, and verification and drawing conclusions. In this study, student errors were analyzed based on Newman's five error indicators, (a) errors in reading questions, (b) errors in understanding questions, (c) errors in process transformation, (d) errors in process skills, and (e) errors in write down the final answer. Based on the results of the analysis, it was found that the types of errors made by Informatics Engineering students in solving the questions of the fundamental method of counting were three, namely (1) errors in receiving information including errors in determining what was asked the cause was not being careful in reading the questions, (2) errors related concepts include: (a) errors in using permutation and combination formulas. The reason is that students cannot understand the meaning of the problem, when to use permutations and when to use combinations. And (3) errors in counting, the cause is because students are not careful.

Abstract

The purpose of this study was to describe students' geometric thinking skills on circle material based on Van Hiele's theory (Visualization, Analysis, Informal Deduction, Deduction, Rigor). The subjects of this study were 3 students of class IX-A SMP Hang Tuah 4 Surabaya based on their initial mathematical abilities (high, medium, and low). The initial mathematical ability data was obtained from data on report cards for the even semester of the 2021-2022 academic year and based on the considerations of the mathematics teacher for class IX-A. This type of research is descriptive qualitative research. Collecting data in this study used tests and interviews. The test instrument used in this study was a circular geometry test in the form of mathematical questions with circle material arranged based on the Van Hiele indicator without stage 4 (Rigor) with the consideration that the research was conducted in class IX SMP so students have not been able to understand the material at stage 4 (rigor). Student with high initial mathematical abilities, geometric thinking abilities is already at stage 2 (informal deduction). Student with medium mathematical abilities, geometric thinking skills is at stage 2 (informal deduction). Student with low mathematical abilities, geometric thinking skills is at stage 0 (visualization).
