Abstract

Bu çalışmanın amacı, cebir öncesi dönemde olan üçüncü, dördüncü ve beşinci sınıf öğrencilerinin fonksiyonel ilişkileri genelleme düzeylerini belirlemektir. Araştırma yöntemi olarak temel nitel araştırma yaklaşımı benimsenmiştir. Araştırmanın katılımcıları cebir öncesi dönemde olan orta sosyo-ekonomik düzeyde yer alan bir okulda öğrenim gören üçüncü sınıflardan 45, dördüncü sınıflardan 36 ve beşinci sınıflardan 35 kişi olmak üzere toplam 116 öğrenciden oluşmaktadır. Veriler araştırma amacı doğrultusunda açık uçlu sorular yardımıyla toplanmıştır. Verilerin analizinde tematik analiz yöntemi kullanılmıştır. Bu bağlamda alanyazında daha önce geliştirilmiş olan fonksiyonel düşünme düzeyleri dikkate alınmış ve bu düzeylerden bazıları bu araştırma kapsamında kullanılmış aynı zamanda bazı düzeylere ilişkin alt düzeyler oluşturulmuştur. Tüm sınıf düzeylerindeki öğrencilerin genel olarak fonksiyonel düşünmenin birçok göstergesine sahip olduğu görülmüştür. Ancak genel kuralı y=mx+n formunda olan ilişkileri genelleyebilme ve temsil etmede bazı öğrencilerin daha çok zorlandığı araştırmanın önemli görülen sonucundan birisi olmuştur. Bu sonuç cebir öncesi dönemde yer alan öğrencilerin fonksiyonel düşünmelerinin geliştirilebilir olduğu göstermektedir. Bu nedenle daha erken yaşlarda fonksiyonel düşünmeyi geliştirici etkinliklerin programlarda ve ders kitaplarında artırılması gerekmektedir.

Early Algebra: The Levels of 3th, 4th and 5th Grade Students’ Generalisations of Functional Relationship

Abstract

The purpose of this study is to determine the students’ levels of generalisation of functional relationships in third, fourth and fifth grade. The design of the study was a basic qualitative research study. Participants were 116 students; 45 from the third grade, 36 from the fourth grade and 35 from the fifth grade from a middle school. The data were collected with the help of open-ended questions. Thematic analysis was used to analyze the data. In this context, the levels of functional thinking previously developed in the literature have been taken into consideration and some of these levels have been used in this research and at the same time some levels of lower levels have been formed. It has been seen that most students at all grade levels have many indications of functional thinking in general but some students have more difficulty in generalizing and representing the general rule y=mx+n. This result shows that the functional thinking of the students in the early algebra period can be improved. Therefore, it is necessary to increase the activities that develop functional thinking in curriculum and textbooks at an earlier age.
