The integration of mathematical modeling with technology and the advantages of technology to

modeling process have become more important in today's fast-growing society. The studies about how the

technology affects the mathematical modeling process and how to use the technology more effectively are

of importance. The purpose of this study is to illustrate how to use GeoGebra in the process of mathematical

modeling. In this study, GeoGebra was used in solution process of a problem designed in accordance with

mathematical modeling and the intended uses of GeoGebra were described in the mathematical modeling

process. The solution of the Height-Foot Length Problem designed by the researchers was carried out taking

into account the seven step modeling process. With this study, it was exemplified how the mathematics

teachers will be able to use the mathematical modeling and the GeoGebra in their lessons. It is thought that

GeoGebra will contribute to the uncovering and the development of modeling skills and will be provided

more conceptual and mathematical thinking by preventing losing in procedures.

Matematiksel Modellemede GeoGebra Kullanımı: Boy-Ayak Uzunluğu Problemi

Öz

Matematiksel modelleme ile teknolojinin entegrasyonu ve modelleme sürecine teknolojinin sağladığı

avantajlar günümüzün hızlı gelişen toplumunda daha önemli hale gelmektedir. Teknolojinin

matematiksel modelleme sürecini nasıl etkilediği ve daha etkili nasıl kullanılabileceğine ilişkin çalışmalar

önem taşımaktadır. Bu çalışmanın amacı, matematiksel modelleme sürecinde GeoGebra’nın nasıl

kullanılabileceğini örneklemektir. Çalışmada, matematiksel modellemeye uygun olarak tasarlanan bir

problemin çözüm sürecinde GeoGebra’dan yararlanılmış ve GeoGebra’nın süreçteki kullanım amaçları

açıklanmıştır. Araştırmacılar tarafından tasarlanmış Boy-Ayak Uzunluğu probleminin çözümü, yedi

basamaklı matematiksel modelleme süreci dikkate alınarak gerçekleştirilmiştir. Çalışma ile öğretmenlerin

matematiksel modelleme ile GeoGebra’yı derslerinde nasıl kullanabilecekleri örneklenmeye çalışılmıştır.

GeoGebra’nın modelleme becerilerinin ortaya çıkarılmasında ve geliştirilmesinde katkı sağlayacağı ve

işlemler içinde kaybolmayı önleyerek daha fazla kavramsal ve matematiksel düşüncenin ortaya çıkarılmasını

sağlayacağı düşünülmektedir.
