Abstract

In learning mathematics, critical and logical thinking processes are needed to solve problems correctly, including material about arithmetic sequences and series, which requires good concentration in studying it. This type of research is descriptive qualitative which aims to analyze students' thinking processes in solving problems of arithmetic sequences and series. The subjects in this research were class XI high school students. One of the abilities developed in learning mathematics is the ability to solve problems. Students can do math problems but are not good enough at analyzing and thinking optimally. This causes students' low ability to solve mathematical problems. The research results showed that students were able to work on calculated reasoning cycle questions. Because, in responding to or answering these questions the subject will generally use ideas that have been researched, and the subject can communicate or understand the methods taken to overcome these problems. Some students who use a semi-reasonable reasoning cycle when evaluated in solving problems are not ready to communicate it in their own words. In understanding a problem, students have used these ideas but not enough and students cannot. don't understand the steps to solve this problem. The equation used is correct, but the steps to overcome it are still inappropriate.

Abstract

Misconceptions or misunderstandings can occur due to additions or deletions of what is inherent in the concept. Misconceptions can cause misunderstandings that cause difficulties for students in understanding the learning process. The aim of this research is to identify several misconceptions that occur among PGMI 3 UINSU students regarding the application of polya theory to plane material. The type of research used in this research is qualitative descriptive research in the form of a test on completing students' mathematics results accompanied by interviews related to flat shape material with the application of polya theory. The results of this research show that there are several misconceptions, namely not including the name of the flat figure in the problem, not giving cm marks for the base and height units, and the planning stage of the formula used being incomplete, not making polya theory steps in working on the problem and not evaluating final results or not writing conclusions. This is because students are not used to writing conclusions and also assume that the final calculation result obtained is the solution to the problem. The type of error found in question number 1 is 31.5% and in number 26.2%. From 39 students, a sample of 19 students was taken. 8 students answered the questions correctly and 11 students made mistakes. It is hoped that this misconception will not happen again to other prospective teacher students.

Abstract

This article identifies various types of misconceptions experienced by UIN North Sumatra students when they solve problems related to mathematical series operations material, as well as to understand the causes of misconceptions among students in this context. This research uses qualitative methods in the form of descriptive research with the data collection method used is a test to identify misconceptions that students may experience. The results of the analysis show that students still often experience misconceptions when solving problems related to geometric series operations. The types of misconceptions identified among students include translation misconceptions, concept misconceptions, sign misconceptions, and systematic misconceptions. The causes of misconceptions can generally be attributed to students, with several factors at play. Misconceptions can occur due to wrong preconceptions that students previously had, incomplete or wrong reasoning in solving problems, and students' abilities that may still be lacking in understanding the material.
