Ekstremum ve Dönüm Noktaları Kavramlarındaki Hataların Düzeltilmesinde GeoGebra Kullanımı

Abstract

In this study, the effectiveness of GeoGebra in correcting the errors and understanding the right ones was examined by taking into consideration the extreme and turning points the possible errors according to expert opinions. The study was designed as a case study, one of the qualitative research methods. It was carried out with 11 prospective mathematics teachers studying in the 3rd grade of a state university in Turkey. In order to reveal the knowledge of prospective teachers of the extreme and turning points, 19 expressions of true-false and interrogative of their causes were presented to the prospective teachers in writing. Then, applications related to the extreme and the turning points were made with GeoGebra assisted education. After 3 weeks, 19 expressions, presented to the prospective teachers before the application, were presented to them again, and 3 prospective teachers were interviewed. The descriptive analysis method was used to analyze the data. According to the findings of the study, a general increase was observed in determining the errors and making the correct explanation after the application regarding the prospective mathematics teachers. The findings of the interviews show that prospective teachers generally found GeoGebra assisted application useful and that they made progress in this regard with this application.

Bilgisayar Destekli Matematik Eğitimi Alanında 2015-2019 Yılları Arasında Yapılan Araştırmaların İncelenmesi

“…Akbaş, 2019;Türkmen ve Soybaş, 2019;Yiğit ve İpek, 2015), üst gruplarda türev/integral (Ör. Karakuş ve Konyalıoğlu, 2018;Sevimli ve Delice, 2016) gibi anlaşılması zor konuların BDE kullanılarak öğretilmesinin amaçlandığı anlaşılmaktadır. Geometri alanında ise üç boyutlu cisimlerin hesaplamalarında BDE'nin kullanıldığı araştırmalara rastlanırken, bu grupta Geogebra, Cabri ve Geometer's Skechpad gibi dinamik yazılımların çok tercih edildiği gözlemlenmiştir.…”
