An Investigation of Item Bias in PISA Science Test in Terms of The Language and Culture

Abstract

In this study, differential item functioning (DIF) analyses of Science items of PISA 2006 tests were carried out between different samplings. Mantel Haenszel (MH), logistic regression(LR) and signed - unsigned area indexes methods were used. The research group of this study consists of the samples of Australia, Canada; England, Turkey. In order to investigate the sources of DIF field specialist opinions were consulted for released  multiple choice items of science test. It is observed that as the linguistic and cultural differences increased between countries, the number of DIF items increased. The number of DIF items varied significantly according to the procedure used. There was not consistency according to DIF detecting method in DIF or nonDIF items. Generally; like other results of bias researchs this research indicated that the main possible reasons for DIF is due to differences in translation, curriculum,cultural relevance, linguistic differences across Turkish and English versions of the tests of released items.
