Abstract

Bu çalışmanın amacı, yatay düzlemde yarışan düzenekler için, yarış sonucunu tahmin etmede kütlenin, ortaokul öğrencileri tarafından nasıl anlamlandırıldığını araştırmaktır. Bu doğrultuda öğrencilerin kütle kavramı hakkında günlük hayattaki gözlemlerinden yapılandırdıkları şemaların, sınıf düzeyi, cinsiyet gibi değişkenler bakımından farklılık gösterip göstermedikleri analiz edilmiştir. Bu amaçla araştırmacılar tarafından geliştirilen ve beş açık uçlu sorudan oluşan Yarış Soru Seti, 738 ortaokul öğrencisine uygulanmıştır. Tarama araştırma deseninin benimsendiği bu araştırmada, öğrenci cevapları betimsel olarak analiz edilmiştir. Elde edilen bulgular, öğrencilerin kütlesi en az olan aracın yarışı kazanacağını belirttiklerini; fakat kütle miktarının yarış sıralaması tahmininde tek ölçüt olarak kullanılmadıklarını göstermiştir.

MAKING MEANING OF MASS VARIABLE IN RACE PROBLEMS

Abstract

This study aims to investigate how middle school students make meaning the relationship between mass of vehicles and their speed on a horizontal plane. Accordingly, students’’ schemes constructed from daily life observations for concepts such as the concept of mass and differences between schemes and variables including level of class and gender were investigated. Race Question Set developed by authors was administrated to 738 middle school students. A descriptive study (relational-screening model) was adopted for analyzing students’ answers. Findings obtained indicated that mass of vehicles was important but that was not a single criterion for predicting race result among students.

Keywords

mass, speed, race prediction, common sense theory of motion, schemes
