Abstract
Bu araştırma, maddenin yapısı ve özellikleri ünitesi çerçevesinde REACT stratejisine yönelik geliştirilen öğretim materyallerinin öğrencilerin kavramsal anlamaları üzerine etkisini incelemeyi amaçlamaktadır. Araştırma deneysel araştırma yönteminin ön test - son test kontrol gruplu deseni ile yürütülmüştür. Araştırmaya deney grubunda 50 ve kontrol grubunda 51 olmak üzere toplam 101, 6. sınıf öğrencisi katılmıştır. Araştırmada REACT stratejisi temel alınarak geliştirilen öğretim materyali sıcak hava balonu ve çalışma prensibi ana bağlamı çerçevesinde gerçekleştirilmiştir. Araştırma verileri, iki aşamalı sorulardan oluşan kavram testi ile toplanmıştır. Kavram testinden elde edilen veriler Mann Whitney-U testine tabi tutulmuştur. Bulgular deney grubunda yürütülen öğretimin kontrol grubunda yürütülen öğretime göre daha etkili olduğunu göstermektedir. Araştırmadan elde edilen bulgular 'maddenin tanecikli yapısı' konusunda öğrencilerin maddelerin gözlenebilir özelliklerini taneciklere yükleyerek, 'fiziksel-kimyasal değişme' konusunda genellemelere giderek, 'yoğunluk' konusunda günlük yaşamda öğrendiklerinin etkisinde kalarak alternatif kavramalar oluşturduklarını göstermiştir. Ayrıca REACT stratejisi temel alınarak gerçekleştirilen öğretim, kavramsal değişim üzerinde etkili olmuş olsa da bilimsel bilgilerle değiştirilemeyen alternatif kavramaların olduğu belirlenmiştir.
The present study aims to investigate the effect of teaching materials developed based on REACT strategy within the scope of „the Structure and Characteristics of Matter‟ unit on the conceptual understanding of students. This is an experimental study with pre-test post-test control groups. This study was conducted with a total of 101 students with 50 students in experimental group and 51 students in control group. The hot air balloon and its working principle are used in the main context of teaching material. Data collection tool is content test consisting of two-step questions. Mann Whitney-U test was applied to the data obtained from the content test. The results from data collection tools indicate that teaching materials based on REACT strategy are more effective than the teachers' teaching materials. The findings obtained from the study demonstrated that students formed conceptions by attributing observable characteristics of matters to particles in „the Particular Structure of Matter‟ subject; by generalizing in „Physical and Chemical Change‟ subject; and with the effect of their daily life experiences in „Density‟ subject. It was seen that there were alternative conceptions that could not be replaced by scientific knowledge even though the teaching materials developed based on REACT strategy were effective in creating a conceptual change.
