The purpose of this study is to determine whether English test items of Undergraduate Placement Exam (UPE) in 2016 contain differential item functioning (DIF) and differential bundle functioning (DBF) in terms of gender and school type and examine the possible sources of bias of DIF items. Mantel Haenszel (MH), Simultaneous Item Bias Test…

This article addresses test translation review in international test comparisons. We investigated the applicability of the theory of test translation error--a theory of the multidimensionality and inevitability of test translation error--across source language-target language combinations in the translation of PISA (Programme of International…

One of the most interesting studies on the role of L1 and contrastive analysis in vocabulary teaching is by Laufer and Girsai (2008). However, due to some methodological issues, their research findings are open to criticism and controversy. The current study aimed to replicate the research with a more rigorous design to re-investigate the…

Under the framework of item response theory (IRT) and generalizability (G-) theory, this study examined the effects of item difficulty on rating reliability and construct validity on both the constructed-response (CR) items and essay items on English examinations. The data collected for this study were students' scores and responses on the two…

Collocation is an often-neglected language form that foreign language teachers and students should focus on to achieve competence in a target language. In this research, the researchers studied purposely to facilitate both second language teachers and students to produce correct and appropriate collocations. The purposes of this research were 1)…

Although foreign language testing has been subject to some changes in line with the different perspectives on learning and language teaching, multiple-choice items have been considerably popular regardless of these perspectives and trends in foreign language teaching. There have been some studies focusing on the efficiency of multiple choice items…

Through the introduction of different dimensions of vocabulary knowledge, depths and breadth dimensions, various studies attempted to examine numerous effective factors on these dimensions. The present study aimed to show the effects of different vocabulary learning styles through extensive and intensive reading programs on depth and breadth…

Even if national and international assessments are designed to be comparable, subsequent psychometric analyses often reveal differential item functioning (DIF). Central to achieving comparability is to examine the presence of DIF, and if DIF is found, to investigate its sources to ensure differentially functioning items that do not lead to bias.…

This article reports the results of a study of potential sources of item nonequivalence between English and Chinese language versions of a cognitive development test for preschool-aged children. Items were flagged for potential nonequivalence through statistical and judgment-based procedures, and the relationship between flag status and item…
