Nowadays there are several challenges for English teachers as well as researchers regarding how to teach foreign language pronunciation more effectively. The current study aimed to explore the effect of computer-assisted pronunciation teaching (CAPT) on Persian monolinguals and Turkmen- Persian and also Baloch- Persian bilinguals’ pronunciation considering production and perception. A sample of 48 female mono and bilingual 7th-grade students participated in this study and made the experimental and comparison groups. All the participants took the Oxford Placement Test and accordingly were in the beginner level of English language proficiency (95.83% of the participants’ scores ranged from 0 to 15). The experimental group experienced a technology-based instruction while the comparison group benefited from traditional listen and repeat method of pronunciation teaching. Two Two-way between-group ANOVAs were used to define the influence of CAPT on pronunciation production and perception of the mono and bilingual participants. The results of the study indicated that CAPT had a significant effect on pronunciation production while pronunciation perception was comparatively more enhanced through the traditional method. Regarding mono and bilingualism, it was also found that bilinguals significantly outperformed monolinguals in pronunciation production in both groups while there was no significant difference between them in pronunciation perception. There were also no interaction effects for pronunciation perception or production scores. The results generally showed that CAPT can be beneficial specifically when it is used along with traditional methods at schools in beginner levels.

The aim of the current study was twofold: (1) to validate the internal structure of the general English (GE) section of the university entrance examination for Ph.D applicants into the English programs at state universities in Iran (Ph.D. UEE), and (2) to examine the factor structure invariance of the Ph.D. UEE across two proficiency levels. Structural equation modeling (SEM) was used to analyze the responses of a random sample of participants (N=1009) who took the test in 2014 to seek admission to English programs at Iranian state universities. First, four models (unitary, uncorrelated, correlated and higher-ordered) were estimated and compared to find the model that best represented the data. Then, the factor structure invariance of the test across two proficiency levels was explored using multigroup confirmatory factor analysis. The higher-order and correlated three-factor model showed the best fit to the data. The result also showed that the structure of the test remained invariant across both proficiency levels. These results supported the multi-componential view of language proficiency. It was found that there is no relationship between levels of language proficiency and the structure of the test. However, the results called into question the score-reporting policy for the PhD UEE and led to the conclusion that a single total score does not reflect the structure of the test.

The major objective of this experimental research was to assess the differences between two varieties of focus on form instruction, namely proactive and reactive across multimodal vs. traditional input settings in both comprehension and production of modal auxiliaries. The participants of the study were 75 Iranian English as a foreign language (EFL) high school students at the elementary level in three classes. The students in each class took part in a pre-test including both comprehension and production items. Then, they were randomly exposed to one of the three types of grammar instruction, i.e. proactive focus on form in which students were exposed to multimodal input through preplanned techniques of input enhancement and input flood, reactive focus on form in which the tasks occurred in multimodal episodes including negotiation and correction by the instructor through recasts, clarification requests, and repetition techniques. Lastly, in the control group, the students were provided with a pamphlet and their teacher’s explanations. The post-test was then administered to the three groups, and the results were analyzed by conducting a one-way-analysis of covariance (ANCOVA) which revealed a significant difference among these three groups. The results showed that the proactive group outperformed the reactive and control groups both in the comprehension and production of modal auxiliaries. At the end of the experiment, a brief survey which was accomplished through an interview revealed that the majority of the students highly favored PowerPoint presentations, teacher's explanations, and video clips respectively.

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 current paper intends to exploit the Many Facet Rasch Model to investigate and compare the impact of situations (items) and raters on test takers' performance on the Written Discourse Completion Test (WDCT) and Discourse Self-Assessment Tests (DSAT). In this study, the participants were 110 English as a Foreign Language (EFL) students at Vali-e-Asr University of Rafsanjan in Iran. The students were asked to complete the WDCT and rate themselves on that test. Four raters scored the WDCT tests. According to the FACETS results, there were significant differences in students' performance between the two methods. The stable fit statistics and differing levels of difficulty measures for each test method indicated that each test had a unique way of differentiating the test taker's pragmatic ability. Based on the results, both DSAT and WDCT are acceptable measures for pragmatic ability; however, there are some fitness problems in DSAT. This shows the unpredictable pattern of ratings in the DSAT. It is recommended to have rater training to obtain more accurate results from the DSAT. Finally, the implications were discussed.
