Fen Eğitiminde Kavram Yanılgıları, Grafikler ve Matematik Öğretimi

Öz

Bu çalışmanın amacı, kimya öğretmenlerinin, kimyasal reaksiyonlardaki hız ve denge konusunda mevcut olan bazı kavram yanılgılarının farkında olup olmadıkları ve kullanılan grafikler üzerinde bu yanılgıların farkındalıklarını tespit etmektir. Betimsel araştırma yönteminin kullanıldığı bu çalışmada veriler yüz yüze görüşmelerle elde edilmiştir. Elde edilen bulgular sonucu öğretmenlerin ilgili konudaki kavram yanılgılarının farkında olma ve grafik çizme ile ilgili problem yaşamadıklarını, buna karşın grafik üzerinde bu yanılgılarını açıklamada yetersiz kaldıkları sonucuna ulaşılmıştır.

Anahtar Kelimeler

• Kavram yanılgısı, grafikler, görselleştirme, kimyasal reaksiyon, reaksiyon hızı ve denge, türev.

Misconceptions, Graphs and Teaching Mathematics in Science Education

Abstract

The aim of this study is to detect if teachers of chemistry are aware of some misconceptions about chemical equilibrium and speed, and their awareness of those misconceptions on the graphs used. The data have been obtained by face to face interviews in this study for which descriptive research method has been used. In respect of the findings it has been concluded that teachers don't have problems with awareness of misconceptions and drawing graphs about the related subjects but they are incompetent at explaining the misconceptions on the graph

Keywords

• Misconception, graphs, visualization, chemical reactions, the rate and the equilibrium of reactions, derivative
