Effect size reporting in educational research

Öz:

Bu araştırmanın amacı, eğitim alanında Türkiye kaynaklı yayımlanan ve SSCI’da taranan akademik bilimsel dergilerde yayımlanan makalelerde etki büyüklüğü raporlanması durumunu araştırmak ve okuyuculara etki büyüklüğü, hesaplanması ve raporlanması konularında bilgi sunmaktır. Araştırma kapsamına alınan dört dergide 2007-2011 yılları arasında yayımlanan toplam 990 makale incelenmiş; bunlardan etki büyüklüğü raporlanmaya uygun olan 480 tanesi araştırma kapsamına alınmıştır. Araştırma sonunda 480 makalenin sadece 35’inde (%7.2) etki büyüklüğü raporlandığı; bunların da 21’inde raporlanan etki büyüklüklerinin aynı zamanda yorumlandığı görülmüştür. Çalışmadan elde edilen sonuçlar incelendiğinde dergiler arasında etki büyüklüğü raporlama ve yorumlama açısından anlamlı bir farklılık olmadığı görülmüştür χ2 (3, n = 483) = 7. 30, p = .06, Cramer’s V = .12.
