Considering the paramount importance of writing logical arguments for college students, this study investigated the effect of dynamic assessment (DA) of Toulmin Model through teacher- and collective-scaffolding on argument structure and overall quality of argumentative essays of Iranian EFL university learners. In so doing, 45 male and female Iranian EFL learners taking part in the study were randomly assigned into three groups (two experimental groups including the teacher- and collective-scaffolding and one control group), each consisting of 15 learners. Toulmin Model of argumentation was used as an instructional tool in this research. The necessary data were collected through a pre- and post-test argumentative essay. During the experiment, the dynamic assessment groups wrote and revised their essays in response to teacher’s or peers’ supportive dialogue and zone of proximal development (ZPD) sensitive feedback on the argument structure of their essays; whereas, the control group did not receive such mediation and they were evaluated on their own independent performance. The results of statistical analyses carried out on post-test scores on argument structure and overall quality of the essays pointed out to the outperformance of the teacher- and collective-scaffolding groups on both variables. Furthermore, follow-up Post-hoc analyses revealed no significant difference between the teacher- and collective-scaffolding groups in terms of the overall quality of the argumentative essays. However, the statistically significant difference between the two experimental groups with regard to the argument structure indicated the outperformance of the teacher-scaffolding over the collective group. The obtained results support the fact that autonomy and improvement cannot be thrust upon learners, rather they need to be assisted wisely towards independence.

AbstractThe interference of the native language in acquiring a foreign language is unavoidable. In an attempt to explore the phenomenon why this occurs, the study was conducted in English as a foreign language writing. The study also investigated how the native language interference occurred in the writing process. In fact, this qualitative study explored the reasons and the process of native language interference in writing performances of EFL learners. The data were collected from Thai undergraduate students through semi-structured interviews. Results obtained from the analysis of this study suggested that the reasons of native language interference in EFL writing were found in three main themes: learning strategies of language learners, inadequate knowledge of the target language, and attitude towards English. Furthermore, the interference of the native language appeared in the initial stage and repeatedly occurred throughout the entire writing process. Finally, the suggestions related to the teachers’ awareness of the problematic area, the use of English as the classroom language, and the use of monolingual dictionary are offered to the EFL writing instructors in order to help their EFL students to minimize the errors caused by the native language interference.

This study investigated the impact of interaction and output modality on vocabulary learning and retention of EFL learners. To investigate the impact of Interaction, solitary (n =69) and collaborative (n =62) groups served as experimental and No Interaction No Output (n =26) as control group. To address the effect of modality, spoken (n =39) and written (n =31) modalities served as experimental and No output modality (n =26) as control group. The study was done in 8 weeks. The groups read passages with target words highlighted. Solitary and collaborative groups reconstructed the passages individually or in dyads. The spoken and written modality groups reconstructed them in the respective modality. Then, pretest, immediate, and delayed posttests were administered. The ANOVA results showed that the collaborative group outperformed the other groups and spoken modality outperformed the written modality group focusing on interaction and modality separately. The 2×2×2 ANOVA results showed significant main effects for time, interaction, and output modality. An ‘interaction’ effect was found between time and interaction, time and modality, and modality and Interaction. The ‘interaction’ between time, Interaction, and modality was insignificant. The findings have implications for language teachers, syllabus designers, and language testing experts.

This paper reports a study which investigated if there was a match between students’ English vocabulary size and the vocabulary load of a locally produced textbook. The analysis of the passages of the pre-university English textbook currently in use in Iran’s education system using RANGE program indicated that in order to comprehend the texts, students need to know not only words from 2000 high frequency word list, but also words from academic and low frequency lists. On the other hand, results of the 2000 vocabulary level test administered to 464 Iranian pre-university students, male and female, showed that students did not possess sufficient vocabulary knowledge in order to comprehend the texts and that their vocabulary knowledge was limited far below 2000 words. Other analyses of the textbook, including exercises and word glosses provided more evidence for the inadequacy of the textbook. The paper concludes that the pre-university textbook is flawed in terms of the required principles and standards in materials development which results in students’ frustration and disappointment in learning English. The findings of the study are discussed, which should be of much interest to local and international ELT stakeholders, especially textbook writers.

The present study aimed to explore the impact of teaching critical thinking skills through applying debate on the use of communicative strategies. At first 60 intermediate students were selected and placed in two homogenous groups of control and experimental through passing Nelson test. Then, a critical thinking appraisal was run to the two groups both before and after the treatment. The treatment that experimental group received during the term was 10 sessions of debate as a classroom activity. The analysis of the collected data exhibited significant difference between the two groups concerning critical thinking skill. The results showed that the subjects in experimental group were oriented toward critical thinking. In a subsequent stage, the subjects were asked to write a story in English based on a series of related pictures. Then, the number of communicative strategies including achievement and reduction ones were counted carefully. A t-test was run to find whether the differences between the two groups regarding the use of such strategies were significant or not. The results revealed that the subjects in experimental group used more achievement strategies. Concerning the use of reduction strategies by the two groups no significant difference was found.

This paper reports on an investigation of native language-based differential item functioning (DIF) across the subtests of Iranian Undergraduate University Entrance Special English Exam (IUUESEE). Fourteen thousand one hundred seventy two foreign-language test takers (including four groups of Azeri, Persian, Kurdish, and Luri test takers) were chosen for the study. Uniform DIF (UDIF) and Non-uniform DIF (NUDIF) analyses were conducted on data from the four versions of IUUESEE. After establishing the unidimensionality and local independence of the data, DIF findings showed that Luri test takers were more advantaged than other native language groups across the subtests. NUDIF analysis uncovered that almost all subtests functioned in favor of low-ability test takers who haven’t been expected to outperform high-ability test takers. A probable explanation for native language-ability DIF was that Luri and low-ablity test takers were more likely to venture lucky guesses. Thoughtless errors and guessing, test-wiseness, overconfidence, stem length, unappealing distractors, and time were proposed as possible causes of DIF in IUUESEE. It was also found that the reading subtest included the large number of items with significant DIF.

Argument maps as schematic representations of arguments and their logical and evidential relationships are effective diagrams for instruction in education as well as in L2 development. However, their use for teaching L2 writing in EFL contexts has not been adequately studied. Therefore, this study investigated the effect of argument mapping instruction on Iranian EFL learners’ writing achievement and writing components, including grammar, coherence, cohesion, and task accomplishment in expository and descriptive essays. The participants were 60 intermediate EFL learners at Fadak language institute in Tehran. The selected participants were randomly divided into two groups: an experimental and a control group, each including 30 participants. Materials, coursebooks, and the teacher were the same for the study groups. However, the participants in the experimental group received specific instruction about the use of argument maps before and during their writing. After 10 sessions of treatment, the learners in the two groups were asked to write a descriptive and an expository paragraph. The paragraphs were rated by two raters and the final score was the average of the scores given by the two raters. The results of the data analysis revealed that argument mapping strategies had significant improvement impact on expository and descriptive writing tasks and could improve participants’ writing in terms of grammar, coherence, cohesion, and task achievement. However, argument mapping was not beneficial in improving the vocabulary of study participants’ writing. Findings of the study suggest that EFL language instructors and learners can use argument maps for teaching descriptive and expository writing.
