7. Sınıf öğrencilerinin birinci dereceden bir bilinmeyenli denklemler konusuyla ilgili hataları ve kavram yanılgıları

Abstract

The aim of this study is to identify students' mistakes and misconceptions about first-order equations with one unknown. Knowing the students' misconceptions and mistakes about first-order equations with one unknown is important in terms of learning the other subjects on which this subject is based correctly and informing the teachers about possible mistakes and misconceptions about this subject. The method of the research is the case study model, one of the qualitative research methods. This research was carried out with a total of thirty one 7th grade students in three secondary schools in Kars. Data were collected by applying an achievement test consisting of open-ended questions on the subject of firstorder equations with one unknown, which was developed by the researchers. The analysis of the data was made with descriptive analysis, one of the qualitative data analysis approaches. Considering the results of the research, it was seen that the students made a lot of mistakes and had misconceptions about first-order equations with one unknown. The fact that there were many mistakes and misconceptions in the answers showed that the subject of equations with one unknown was difficult for students to understand. Errors and misconceptions were classified according to their types and examined on the basis of learning outcomes. Looking at the results, the most common mistakes are "errors related to the establishment of the equation suitable for the given problem", "errors related to the crossover rule" and "random errors", and the most common misconceptions are "misconceptions about the concepts of unknown and variable", "equation without the unknown", misconceptions of "trying to write" and "not being able to operate with variables". Suggestions are listed according to the results.
