Bu araştırmanın amacı, 8. sınıf öğrencilerinin görsel ve cebirsel ifadeler konusundaki hata ve kavram yanılgılarını incelemektir. Çalışma gurubunu Afyonkarahisar ilinde sekizinci sınıfta öğrenim gören 120 ortaokul öğrencisi oluşturmaktadır. Veriler basit görsel ve şekil örüntülerini cebirsel ifade etmeyi gerektiren biri çoktan seçmeli 4’ü açık uçlu sorudan oluşan cebir testi ile toplanmıştır. Veriler betimsel ve içerik analizi yapılarak analiz edilmiştir. Araştırma sonucunda cebir geometri ilişkisini kuramayan öğrencilerin cebirsel ifadeleri anlamakta zorlandıkları ve örüntüden cebirsel denkleme geçemedikleri tespit edilmiştir. Ayrıca öğrencilerin basit görsel ve cebirsel ifadelerdeki hataların yanlış cebirsel işlem seçimi, cebirsel ifadelerde parantezi dikkate almama, şekil örüntüsünü yanlış yorumlama ve aritmetik işlem hatasından kaynaklandığı görülmüştür. Aritmetikten cebire geçişi kolaylaştırmak amacıyla cebir öğretiminde somut materyallerden ve görsellerden daha çok yararlanılması önerilir.
The objective of this study is to study the errors and conceptual errors of the students of 8th grade in the subject of visual and imaginary expressions. The study group consists of 120 high school students studying in the 8th grade in Afyonkarahisar province. The data that requires simple visual and shaped samples to be expressed in gabbage has been collected with a gabbage test consisting of an open end question, which has already been selected. The data has been analyzed through visual and content analysis. The study found that students who were unable to establish a geometry relationship were difficult to understand the geometry expressions and were unable to pass the sample to the geometry equation. It has also been found that the errors in simple visual and gabarit expressions of the students are caused by the wrong gabarit process selection, the lack of consideration of paranthesis in gabarit expressions, the wrong interpretation of the shape sample, and the arithmetic process error. In order to facilitate the transition from arithmetic to gabbage, it is recommended that gabbage teaching uses more material and images.
The aim of this study is to examine the errors and misconceptions of 8th-grade students on visual and algebraic expressions. The study group consisted of 120 middle school students studying in the eighth grade in Afyonkarahisar province. Data were collected with an algebra test consisting of multiple-choice and four written answers question that require an algebraic expression of simple visual and shape patterns. Data were analyzed with descriptive and content analysis. As a result of the research, it was determined that students who could not establish a relationship between algebra and geometric shape had difficulty in understanding algebraic expressions and could not transit from the pattern to the algebraic equation. In addition, it was observed that the errors in simple visual and algebraic expressions of the students were caused by incorrect algebraic operation selection, ignoring parentheses in algebraic expressions, misinterpreting the shape pattern, and arithmetic operation error. In order to facilitate the transition from arithmetic to algebra, it is recommended to use more perceptible materials and visuals in algebra teaching.
