Abstract

Bu çalışma ile proje tabanlı öğrenme yaklaşımının öğrencilerin merkezi eğilim ve yayılım ölçülerine yönelik istatistiksel okuryazarlık seviyelerine etkisinin ortaya çıkarılması amaçlanmıştır. Yarı deneysel çalışma yönteminin benimsendiği çalışmada, deney grubunda proje tabanlı öğrenme, kontrol grubunda ise geleneksel yaklaşım etkinlikleri yürütülmüştür. Geliştirilen veri toplama aracı gruplara uygulama öncesi ve uygulama sonrası uygulanmıştır. Elde edilen ham puanlar Rasch analizi yapan bir program ile lineer puanlara dönüştürülmüştür. Bu lineer puanlar ile ANCOVA analizi yapılmıştır. Uygulama öncesi ve sonrası istatistiksel okuryazarlık seviyeleri kişi madde haritaları ile ortaya konmuştur. Ayrıca deney grubunda yapılan mülakatlar nitel olarak değerlendirilmiştir. Elde edilen bulgulara göre proje tabanlı öğrenme yaklaşımının öğrencilerin merkezi eğilim ve yayılım ölçülerine yönelik istatistiksel okuryazarlık seviyelerini arttırdığı sonucuna varılmıştır.

The Effect Of Project Based Learning On The Statistical Literacy Levels: Central Tendency And Dispersion Measures

Abstract

This study investigates the effect of project based learning approach on students’ statistical literacy levels towards central tendency and dispersion measures. Quasi-experimental research model was used. A test was developed and applied as pre and post-tests. The data were analysed using Rasch (1980) model. All raw scores transformed lineer scores by Winsteps 3.72 and ANCOVA analysis is used. Person item maps were produced and study supplemented with qualitative data. The results of the study revealed that the project based learning increased students’ statistical literacy levels towards central tendency and dispersion measures in the intervention group.

Keywords
