One of the most important needs in learning a second or foreign language is vocabulary acquisition. Certainly, failure to keep vocabulary in mind is a problem for both typically-developing learners as well as those with a learning disability (LD). This language demand requires teachers to use techniques in order to reinforce vocabulary recall. The current study is an attempt to investigate the effect of two post-teaching vocabulary learning techniques of diglot-weave and cooperative learning on vocabulary knowledge of LD students and to compare them with the common instruction of picture-word definition. To this end, 90 Iranian female LD students from 10 intact classes in two Junior Exceptional Schools in Shiraz were randomly assigned to one of the three groups. After the intensive teaching sessions, the test was administered to examine their vocabulary recall performance in each group and after a two-week interval, the same test was used to examine their vocabulary retention. The results by conducting the one-way ANOVA indicated that both experimental groups of diglot-weave and cooperative learning techniques outperformed the control group of picture-definition in the vocabulary recall and retention tests. However, there was no significant difference between the performance of diglot-weave and cooperative learning groups. Therefore, the findings of the present study could provide useful implications for foreign language teaching programs particularly in Special Education and students with LD.

The current study investigated the impact of an interventionist model of dynamic assessment, using a repetitive process of pretest-teach-posttest design, on Iranian EFL learners’ reading comprehension and classroom engagement. To this end, 40 intermediate participants were selected through convenient sampling from among the English majors of a university in Kerman, Iran, and assigned to two control and experimental groups, each including 20 students. Then, during 4-month period, the experimental group was exposed to reading comprehension class, using an interventionist model of DA, while the control group did not receive ant dynamic assessment program. At the end of the treatment, the participants’ scores on the pretest and post-test were statistically compared. The obtained results revealed that the experimental group significantly outperformed the control group on the scales of reading comprehension skill. A change was also observed in the classroom engagement of the experimental group, but not for the control group. Indeed, the results showed that dynamic assessment can boost participants' performance in a practical and effective way, not only in terms of reading performance but also in terms of motivating more classroom engagement among EFL learners. This finding has implications for teachers to design more efficient courses which are the ultimate goal of education.  

This study examined the development of text complexity for the past 25 years of reading comprehension passages in the National Matriculation English Test (NMET) in China. Text complexity of 206 reading passages at lexical, syntactic, and discourse levels has been measured longitudinally and compared across the years. The natural language processing tools used in the study included TAALES, TAALED, TAASSC, and TAACO. To compare the differences across the years at various levels of text complexity, ANOVA and MANOVA tests were conducted. The results suggested that lexical level text complexity revealed the most evident changes throughout the years, lexical sophistication, density, and diversity levels of the most recent years of reading passages have increased remarkably compared to the early years. The syntactic level text complexity indicated a moderate elevation toward the recent years of reading passages. For the discourse level text complexity, regarding cohesion, insignificant fluctuation occurred throughout the years and the general trend was not necessarily increasing. Combined, the results indicated that text complexity of the reading comprehension passages in the NMET over the past 25 years had been steadily increasing by including more low frequency and academic vocabulary, diversifying vocabulary in the passages, and complicating sentence and grammatical structures. The results were further examined against the general curriculum standards and guidelines to analyze whether the changes were reflected in the policies. It showed that the exams required a much larger vocabulary size than the number indicated in the guidelines, suggestions for test designers and pedagogical practices were provided accordingly.

Despite the critical relationships among pragmatic action, context, and linguistic vs. non-linguistic resources for producing various adjacency pairs in foreign or second language (L2) exchanges, their interplay has not been adequately investigated. Therefore, the present study examined these relations in the production of request-refusal adjacency pairs. The needed data were collected from 108 upper-intermediate to advanced EFL learners. Three hundred conversations were audio-recorded from learners’ role-plays that involved making request-refusal adjacency pairs. MAXQDA software was used for data transcription, codification, and analysis. Data analysis revealed that request-refusal adjacency pairs were co-constructed in discursive contexts through multiple turns using both linguistic and nonlinguistic turn construction units (TCUs). Learners significantly used more linguistic rather than nonlinguistic TCUs and more sentential and clausal TCUs than phrasal and lexical TCUs. Moreover, the use of pauses and continuers was significantly more than laughter, facial expression, and body language. These findings have some pedagogical implications for teachers to raise learners’ awareness of context, action, and linguistic and nonlinguistic TCUs in the production of speech act adjacency pairs.

Placing non-native speakers of English into appropriate classes involves mapping placement test scores onto proficiency levels based on predetermined cut scores. However, studies on how to set boundaries for different levels of proficiency have been lacking in the language testing literature. A top-down approach to standard setting in which a panel of experts set cut scores has dominated the typical standard setting procedure. A less utilized approach is to proceed bottom-up by clustering learners based on test scores. The purpose of this study was to fill this gap by examining Education Testing Services (ETS)’s mapping of TOEFL® iBT Test scores to the Common European Framework of Reference (CEFR) levels. The study examined TOEFL® iBT score data from ICNALE (International Corpus Network of Asian Learners of English) and conducted optimal Kernel Density Estimation to find peaks in the distribution of test scores. In addition to the number of peaks, the local minima of the resulting distribution were chosen as boundaries of cut scores for delineating different ability groups. This method of separating scores, also known as contrasting groups, finds clusters of test takers based on maximum differences in scores. The results showed that ETS’ guide for cut scores linking to CEFR levels was comparable to Kernel Density Estimation with some exceptions, namely two out of three cut scores were found to be similar. Implications are discussed in terms of test-centered versus examinee-centered method of standard setting and the need to consider the demographics of the examinee population in determining cut scores.

Intralingual translation is mainly motivated by the intention to modify the text to facilitate the listener's understanding. The present study attempts to examine the differences between VOA Special English and Regular English due to intralingual translation at the levels of phonology, lexicon, and syntax. To this end, 36 samples of passages of varying lengths dealing with academic discourse from non-modified (Regular English) and VOA’s modified (Special English) corpora were randomly selected and analyzed. The comparative analysis showed a significant difference between the modified and non-modified corpora in speech rate, syntax, and lexicon. Further investigation revealed that Special English was characterized by slower readings, increased pauses and tone units, more frequent and limited words, no idioms, repetitive and unmarked nominal clauses, and impersonal subjects in active voice structures. The findings of the study have implications for English teachers and material developers.

The main objective of this qualitative-quantitative content analysis study was to compare IELTS Academic and TOEFL iBT four modules in terms of the cognition and knowledge dimensions of Revised Bloom’s taxonomy. To this end, two authentic tests including all major modules of speaking, listening, reading, and writing in each domain, namely iBT TOEFL and IELTS Academic exams were analyzed qualitatively and quantitatively. These tests were randomly selected from the collection of authentic tests available in trustworthy resources. The contents of these tests were codified using a coding scheme developed by Razmjoo and Kazempourfard (2012). In this coding scheme, English alphabets and numbers were assigned to levels of cognition and knowledge, respectively. The results indicated that in general TOEFL iBT codes are more inclined toward the higher orders of thinking and knowledge and the codes are not noticeably divergent; while, the majority of the codes in the IELTS Academic test are skewed toward the lower codes of the BRT. This shows the higher stance of the TOEFL iBT test concerning the higher orders of thinking and knowledge in the BRT. A significant difference was also found between the TOEFL iBT and IELTS Academic tests concerning the highest and the lowest levels of BRT.

Global EFL coursebooks are used in numerous educational contexts throughout the world based on the assumption that they are the optimal source of English educational input. Their widespread use calls for a systematic analysis of these coursebooks using a framework that can reveal their defining characteristics. One such framework is the knowledge process framework, which is based on the multiliteracies pedagogy. The present study deployed this framework in an attempt to analyze seven widely taught coursebooks in the Iranian context. The findings revealed that knowledge processes of "analyzing functionally" and "applying appropriately" were more frequent in the analyzed coursebooks and the other knowledge processes were present in lower numbers. Based on the findings of the study, EFL teachers in the Iranian context are encouraged to include more activities with the knowledge processes of "analyzing critically" and "applying creatively" to address the absence of these knowledge processes while teaching the global coursebooks.

This study aimed to investigate the syntactic errors that the Iranian deaf and hearing-impaired (DHI) make in their L2 writings. To this purpose, 60 male and female Iranian DHI students with different social status were selected, through convenience sampling procedure, as participants from among the students of a deaf community in Bandar Abbas, Iran. Their general writing performance was assessed through a proficiency test (pre-test) before they received a six-week writing instruction, in which they were provided with model written utterances and common syntactic points such as sentence order, word order, subject/verb agreement, etc. At the end of the treatment, they were given two topics and asked to write short paragraphs (post-test). Then, different syntactic errors were spotted, analyzed and categorized based on Keshavarz’s linguistic taxonomy of errors. The obtained results indicated that the writing quality of the participants improved from pre-test to post-test. It was also found that majority of the participants committed more syntactic omission errors than syntactic addition errors and syntactic substitution errors. It was further found that syntactic errors in written language were not affected by the gender and social class of the participants. The findings of this study provide empirical evidence for teaching syntactic order to deaf and hearing-impaired students in order to enhance their L2 writing performance.
