Abstract

The purpose of this study is to describe the mistakes of male and female students in solving numeracy AKM problems based on Newman procedures. The method used in this study is a qualitative descriptive method. Some of the results obtained from this study are: (1) mistakes made by male students including comprehension errors occurred because students read the questions once quickly and did not know which ones to write because the questions were too long, process skill errors occurred because students were not careful in calculating multiplication and division operations, and encoding errors occurred because students were in a hurry to do the problems; (2) mistakes made by female students include comprehension errors occurring because students read the questions once and do not know which ones to write because the questions are too long, transformation errors occur because students do not know the formula for finding averages, process skills errors occur because students are not able to calculate correctly, and encoding errors occur because students are not careful in reading what is asked in the questions.(3) The most dominant mistake made by male and female students is comprehension error. This mistake occurs because students read the questions only once, making them unable to fully understand the information provided in the questions and not knowing which points to write down due to the questions being too lengthy.

Abstract

The objectives of this study are: (1) To describe the analogical reasoning of class XI MAN 1 Poso students in the material of geometric sequences from field independent cognitive style and field dependent cognitive style. This type of research is descriptive research using a qualitative approach. The subjects in this study were two students of class XI MIPA MAN 1 Poso even semester 2021/2022 consisting of one RM student with FI cognitive style and one FN student with FD cognitive style. The students' cognitive style data was obtained by giving the GEFT test, while the students' analogy reasoning data were collected from the analogy reasoning test and interviews. The results of this study indicate that (1) field independent cognitive style students' RM fulfills all stages in each indicator of analogical reasoning and can explain the analogy used, namely in the source and target problems there are similarities or analogies in the solution, namely using the nth term formula. in the geometric sequence, namely  so it is included in high analogical reasoning. (2) While the field dependent cognitive style students' FN tend to be less able to fulfill all stages of each indicator of analogical reasoning. At the applying stage, FN has not been able to apply the relational structure of the source problem in solving the target problem, and tends not to be able to explain the analogy used. because it can't explain the analogy used so FN is included in moderate analogy reasoning.

Abstract

This study aims to describe the problem solving of fractional. This type of research is descriptive using a qualitative approach. The subjects of this study were grade VII students of SMP Negeri Model Terpadu Madani Palu consisting of 3 students who were divided into 1 student with high mathematical abilities, 1 student with moderate mathematics ability, and 1 student with low mathematical abilities selected based on processing the final semester exam scores in odd semester 2021/2022. The results showed that students whit high math skills were able to solve problems well based on Polya’s problem solving steps, starting from the stage of understanding the problem, to the stage of re-examining the answers. Students who are mathematically capable are doing mathematical problem solving well at the stage of understanding the problem, the stage of making plans, but at the stage of implementing the plan students are wrong in changing the fraction division operation into the form of fraction multiplication operations, moderately capable subjects do not change the position of the numerator into the denominator and the denominator into the numerator which is the settlement area, the stage of re-checking the students answers only checks again by looking at the results of the answers. Students whit low math abilities have not done problem solving well, that is, they can only rewrite existing information without understanding the existing information, unable to make plans because they feel confused in thinking about plans that must be used to solve problems, cannot carry out problem solving plans. And can’t recheck the answer. This is because students cannot solve the given problem.
