Measurement has been ubiquitous in all areas of education for at least a century. Various methods have been suggested to examine the fairness of education tests especially in high-stakes contexts. The present study has adopted the newly proposed ecological approach to differential item functioning (DIF) to investigate the fairness of the Iranian nationwide university entrance exam. To this end, the actual data from an administration of the test were obtained and analyzed through both traditional logistic regression and latent class analysis (LCA) techniques. The initial DIF analysis through logistic regression revealed that 19 items (out of 70) showed either uniform or non-uniform DIF. Further examination of the sample through LCA showed that the sample is not homogeneous. LCA class enumeration revealed that three classes can be identified in the sample. DIF analysis for separate latent classes showed that three serious differences in the number of DIF items identified in each latent class ranging from zero items in latent class 3 to 43 items in latent class 2. The inclusion of the covariates in the model also showed that latent class membership could be significantly predicted from high school GPA, field of study, and acceptance quota. It is argued that the fairness of the test might be under question. The implications of the findings for the validity of the test are discussed in detail.

Language and culture are now deemed to be co-constitutive; hence English language teaching (ELT) textbooks should incorporate cultural aspects and promote intercultural competence. However, careful decisions should be made as regards to the cultural content of materials and the ways in which culture is represented. This study was an attempt to deconstruct the patterns of cultural representation and intercultural interactions in Interchange textbooks, an ELT textbook series taught to English as a foreign language (EFL) learners in Iran. Using content analysis of texts and images and with the focus on nationality, gender and race, it examined how different cultures were reflected in Interchange 1, Interchange 2, Interchange 3, and whether cultural bias or inequality was present. The quantitative and qualitative data analysis revealed that the white male group was dominant in all three textbooks. And, to use Kachru’s (1985) terms, inner, outer and expanding circle nationalities were represented in the textbooks, with the expanding circle constituting the major nationality, but American culture of inner circle was predominant. Additionally, the interactions were mainly limited to superficial aspects of the target culture although these textbooks sought to show various intercultural interactions. Dominance of male and white characters and the US culture indicated inequality in race and gender, and the superficial treatment of culture in the textbooks. Less attention to the hybrid culture and deeper level of intercultural aspects, i.e. critical reflections, in the textbooks suggests that the materials be supplemented by EFL teachers’ constructive discussion of the cultures that interact.
