Ortaokul Matematik Öğretmen Adaylarının Açı Kavramına Dair Bilgilerinin İncelenmesi

Bu çalışmada ortaokul matematik öğretmen adaylarının açı kavramını tanımlama ve şeklini çizmeye dair bilgileri incelenmiştir. Bu amaçla Türkiye’nin güneyindeki bir üniversitenin ilköğretim matematik öğretmenliği bölümü bahar döneminde geometri dersi alan toplam 151 katılımcıdan veri toplanmıştır. Veri toplama sürecinde katılımcılara temel geometrik kavramların tanım ve çizimlerinin istendiği bir bilgi toplama formu uygulanmıştır. Çalışma kapsamında bu formda yer alan açı kavramına dair veriler analiz edilmiştir. Veriler nitel olarak analiz edilmiştir. Araştırmanın bulgularına göre katılımcıların açı çizimlerinde genellikle ölçüye veya iç bölgeye işaret ettikleri, tanımlarının da bu yönde olduğu görülmüştür. Öyle ki katılımcılar tanımlarının büyük çoğunluğunda açıyı ölçü, yer, bölge veya eğim olarak ifade etmişlerdir. Diğer taraftan katılımcıların tanım yaparken kullandıkları matematiksel dilin sıkıntılı olduğu görülmüştür.

Investigating Prospective Middle School Mathematics Teachers’ Knowledge of Angle

In this study, the researchers investigated prospective middle school mathematics teachers’ knowledge of angle. For this purpose, data was collected from 151 prospective middle school teachers who were enrolled in a geometry course offered in the spring semester in a university located in Southern Turkey. In data collection, the participants were given an instrument in which they were asked to define and draw fundamental geometric shapes. Within the scope of this paper the data involving participants’ definitions and drawings of angle was qualitatively analyzed. The findings indicated that in general the measure and interior region of angle were identified in participants’ drawings and their definitions were in parallel to their drawings. In many of the definitions, they defined angle as the measure, region, area, or slope. Additionally, it was found out that the mathematical language used in the definitions was problematic.
