The generalizability aspect of Construct validity, as proposed by Messick (1989), requires that a test measures the same trait across different samples from the same population. Differential Item functioning (DIF) analysis is a key component in the fairness evaluation of educational tests. University entrance exam for the candidates who seek admission into master's English programs (MEUEE) at Iranian state universities is a very high stakes test whose fairness is a promising line of research. The current study explored gender and major DIF in the general English (GE) section of the MEUEE using multiple-indicators multiple-causes (MIMIC) structural equation modelling. The data of all the test takers (n=21,642) who took the GE section of the MEUEE in 2012 were analyzed with Mplus. To determine whether an item is flagged for DIF both practical and statistical significance were considered. The results indicated that 12 items were flagged for DIF in terms of statistical significance. However, only 5 items showed practical significance. The items flagged for DIF alert the test developers and users to potential sources of construct-irrelevant variance in the test scores which may call into question comparison of the test takers’ performance, especially when the tests are used for selection purposes.

The transformational approach (Freire, 1998) can be achieved through critical pedagogy. The present study describes the development and validation of a questionnaire to access critical pedagogy for evaluating teachers’ perceptions of critical pedagogy in two different contexts i.e. public and private schools. This study used a mixed-method design. In the qualitative phase, 15 experienced high school teachers from public and private schools in Sabzevar, Iran, participated in a semi-structured interview. Based on the result of the constructivist grounded work and the literature review, the main constructs of critical pedagogy were described. Then, an eight-construct operationalization of language teaching was presented, describing the fundamental principles of language teaching from the point of view of critical pedagogy. In the quantitative phase, 180 valid questionnaires, obtained from 59 males and 121 females, were used to run the Confirmatory Factor Analysis using the software LISREL 8.5. This resulted in a 70-item, five-point Likert-scale instrument with satisfactory construct validity which was based on the 21 constructs of critical pedagogy. As a validated measurement, the Critical Pedagogy Questionnaire can be highly useful for the researchers and designers in the field of ELT, English teachers, and instructors to evaluate the perception of their learners on critical pedagogy.

The present study is an attempt to discover the relationships among reflection, role stressors and resilience. To this end, a mixed-method approach was adopted. In the quantitative phase, 122 EFL teachers completed three questionnaires namely English Language Teaching Reflection Inventory, Teacher Role Stressors Scale and Connor-Davidson Resilience Scale. The results of correlation indicated that there is a significant positive relation between reflection and resilience. However, the correlation between reflection and role stressors was found to be negative. Multiple regression revealed that of the five components of reflection, metacognitive and critical reflection are significant predictors of role ambiguity while only critical reflection can predict role conflict. Metacognitive and practical reflection were also found to be significant predictors of teachers’ resilience. In the qualitative phase, fifteen face-to-face interviews were conducted with the participants who had also taken part in the first phase of the study. Data were transcribed, coded and thematically structured based on a grounded theoretical perspective. The two main themes which emerged out of the interviews confirmed that reflection leads to resilience through strengthening teachers’ professional identity while it also leads to resilience or stress through making teachers prepared and knowledgeable. The possible justifications of the obtained results as well as the implications of this study for teaching English and teacher education in EFL context are discussed.
