The Effect of Project-Based Learning on Students’ Statistical Literacy Levels for Inference

Öz

The aim of this study is to define the effect of project based learning approach on students’ statistical literacy levels for inference. To achieve this aim, a test which consists of 10 open-ending questions in accordance with the views of experts was developed. 70 8th grade middle school students, 35 in experimental group and 35 in control group, took this test twice, one before the application and one after the application. All the raw scores were turned into linear points by using the Winsteps 3.72 modelling program that makes the Rash analysis and Ancova analysis were carried out with the linear points. Depending on the findings, there is no significant difference in pre-test and post-test scores on both control and experimental groups. Students’ levels of statistical literacy before and after the application were shown through the obtained person-item maps. According to the results obtained was not observed a significant difference between the experimental and control groups

Proje Tabanlı Öğrenmenin Öğrencilerin Çıkarıma Yönelik İstatistiksel Okuryazarlık Seviyelerine Etkisi

Öz

Bu çalışmanın amacı proje tabanlı öğrenme yaklaşımının ortaokul 8. sınıf öğrencilerinin çıkarıma yönelik istatistiksel okuryazarlık seviyelerine etkisini belirlemektir. Bu amaçla öğrencilerin çıkarıma yönelik istatistiksel okuryazarlık seviyelerini belirlemek için uzman görüşleri doğrultusunda 10 açık uçlu sorudan oluşan bir veri toplama aracı geliştirilmiştir. Geliştirilen bu veri toplama aracı 35’i deney grubu, 35’i kontrol grubu olmak üzere toplam 70 ortaokul 8. sınıf öğrencisine uygulama öncesi ve uygulama sonrası olmak üzere iki kez uygulanmıştır. Testlerden elde edilen tüm ham puanlar Rasch analizi yapan Winsteps 3.72 modelleme programı ile lineer puanlara dönüştürülmüş ve lineer puanlar ile Ancova analizi yapılmıştır. Elde edilen bulgulara göre proje tabanlı öğrenme yaklaşımının öğrencilerin çıkarıma yönelik istatistiksel okuryazarlık seviyelerini etkilemediği sonucuna varılmıştır. Öğrencilerin uygulama öncesi ve uygulama sonrası istatistiksel okuryazarlık seviyeleri elde edilen kişi madde haritaları ile ortaya konmuştur
