Prospective Teachers’ Understanding of Graphs

Öğretmen Adaylarının Grafikler Konusundaki Bilgi Düzeyleri

This study examines prospective teachers’ understanding of graphical representations. The research findings indicate that prospective teachers have difficulties in understanding the relationships between the variables in the graphical contexts. The participants were successful in dealing with the graphs that required quantitative approach, such as dealing with a graph point-by-point or making algebraic manipulations to tease out information embedded in the situation. They were also quite competent to deal with the graphs in a global way providing that the graphs represented real life situations. Nevertheless, very few participants were able to interpret graphs in a global way when the graphs required qualitative approaches, such as an understanding of how changes in the algebraic form of a function could affect the graph of that function

Bu çalışmada Fen Bilgisi ve Sınıf Öğretmenliği bölümlerinde okuyan öğretmen adaylarının grafikler konusundaki bilgi düzeyleri incelenmektedir. Bulgular öğretmen adaylarının değişkenler arasındaki ilişkileri grafiksel ortamda anlama ve yorumlamada ciddi sıkıntılar yaşadıklarını göstermektedir. Katılımcılar noktasal bağlamda grafik okuma veya cebirsel formüller yardımıyla işlemler yapma gibi nicel bilgiler gerektiren ve gerçek yaşamla alakalı durumları temsil eden grafikleri yorumlamada daha başarılı olmuşlardır. Ancak, ‘bağımız değişkende yapılan değişimin grafiğin genel gelişimini nasıl etkileyeceğini anlama’ ve ‘verilen grafiklerin cebirsel/aritmetiksel işlemler yapmadan yorumlanması’ gibi nitel algılar ve global yaklaşımlar gerektiren sorularda katılımcıların başarısız olduğu görülmüştür
