Many textbooks include semantically related words and sometimes teachers add synonyms, antonyms, etc. to the words in order to present new vocabulary items without questioning the possible effects. This study sought to investigate the effect of teaching vocabulary through synonym, semantically unrelated, and hyponym sets based on Higa’s (1963) proposed continuum. A total of 120 Iranian intermediate EFL adults were selected and classified into two high and low language proficient learners based on their PET (2003) scores. They learned the vocabulary items based on the three above-mentioned methods. Learners’ vocabulary achievement was measured using Paribakht and Wesche’s (1993) Vocabulary Knowledge Scale (VKS) in order to assess both the quantitative (number of learnt vocabulary [NLV]) and the qualitative knowledge of vocabulary (depth of learnt vocabulary [DLV]) by administering the same test twice with a two-week interval for obtaining ST and LT results. To address research questions, two independent two-way ANOVAs and two mixed design two-way ANOVAs were conducted. The results revealed that the learners from synonym sets group gained better ST vocabulary achievement quantitatively and language proficiency level proved not to play any significant role in the learners’ vocabulary accomplishment based on belonging to any given group. It was also revealed that quantitatively hyponym, semantically unrelated, and synonym set groups were respectively the most effective methods of clustering that lead to less forgetting in LT which supports Higa’s proposition.

This article sets out to examine the effect of utilizing different culturally-based materials on EFL university students' foreign language reading anxiety, reading comprehension self-efficacy, and reading proficiency within project-based classes. The research was carried out with two classes of intermediate freshmen majoring in English Language Teaching. The comparison group had to present their projects based on the reading passages of the book "Active" (L2 culturally-oriented texts) and the experimental group had to deliver their projects based on their L1 and L2 culturally-based reading texts designed by the researcher. Reading comprehension self-efficacy scale, foreign language reading anxiety scale, and the reading section of the Michigan Test (1998) were administered to students as pre-tests and post-tests at the beginning and at the end of one academic year consisting of two project-based reading courses. ANCOVA was utilized for analyzing the data. The results indicated that although in both groups significant improvements were observed regarding the three aforementioned variables, it was the experimental group that showed significantly less degrees of anxiety, compared to the comparison group. However, no differences regarding reading self-efficacy and reading proficiency were observed between the two groups. The findings of this study suggest that EFL teachers, material developers and syllabus designers can take advantage of cultural familiar texts when generating their own learning materials.

To investigate the effects of etymological elaboration, contextual pragmatic clues, and lexical knowledge on L2 idioms comprehension and production, 60 male intermediate level EFL students in three groups were selected. Each group was randomly assigned to one treatment condition. Group one participants were presented with the etymological explanation of idioms. In group two, the same idioms were presented in short, familiar contexts, and in the third group, the participants focused on the exact meaning of the constituent parts of each idiom. At the end of the experimental period, comprehension and production posttests of idioms were administered. Two one–way ANOVA procedures were used to analyze data. Results showed that the participants of the etymological elaboration group performed significantly better than the participants of the lexical knowledge group on idiom production. The differences between the means in all other comparisons were not statistically significant. These findings may have implications for teachers, learners, and syllabus designers.

The distribution of the allophones of /?/in certain contexts involves free variation and gradient preferences. An organized survey was conducted to elicit the judgments of 37 native Persian speakers concerning the well-formedness of /?/allophonic behavior in five different phonological positions. The results showed that the differences in judgment between the various categories are not just the result of random variations, but are an authentic reflection of the underlying structural differences. Following Boersma and Hayes (1999) and Hayes (2000), a stochastic model is proposed within optimality theory to account for the gradient judgments involved. The model assumes that constraints are arranged along a continuum of constraint strictness, with a band of strictness value assigned to each. When the strictness bands of two constraints overlap, then both rankings of the two constraints are equally available for the generation of outputs, yielding free variant forms. However, when a particular form can be generated only by assigning a constraint a strictness value (/?/ or /??/) within a designated “fringe” of the strictness band, the model generates the form marked with an intermediate degree of well-formedness.

This study sought to evaluate the usefulness and desirability of the English textbooks for Iranian second grade students in senior high school, Vision 2. To this end, the extent to which the textbooks materials satisfy the prescribed curriculum was explored based on Littlejohn’s (2011) evaluative framework. Employing stratified random sampling, a total of 12 private and public senior high schools (six girl students and six boy students) were selected randomly among all the schools located in the six education districts in Isfahan. To select the teacher participants, a convenience sampling method was employed and those who agreed to be surveyed took part in the study. The 20 teachers who participated in this study have been teaching Vision 2 since the beginning of 2017 fall. The process of the content analysis deals with a deeply analytical content evaluation based on a framework containing different parts (objective description analysis, subjective analysis, subjective inference) done by a teacher committee. The results revealed that there is a need to adapt the materials to the target situation of use. Such adaptation needs to cover both design- and publication-oriented aspects of the materials. As a practical implication, the findings may urge the developers of the textbooks to launch a modification project relying upon the results of the systematic phase, therefore, it may enrich English teaching and learning material in Iranian high schools.

الگوی غالب در تعاملات کلاسی یک توالی سه بخشی تحت عنوان آی آر اف (IRF) (مبادرت معلم، پاسخ شاگرد و بازخورد معلم) می باشد (سینکلر و کلتهارد، 1975). گرچه این الگو دارای مزایای تعاملی خاصی است، ولی به دلایلی، به ویژه به واسطه ی ایجاد فرصت مشارکت محدود برای شاگردان (کاسپر، 2001)، مورد انتقاد قرار گرفته است. به همین سبب، کنش جایگزین معطوف به اعتلای مبادرت و عاملیت شاگرد در تعاملات کلاسی از طریق برون رفت از آی آر اف می باشد. اما وقتی ساختار تعامل معلم محور باشد، آی آر اف کانون تعامل گشته و برون رفت از آن دشوار خواهد بود. مطالعه ی حاضر به دنبال پاسخی برای دو پرسش تحقیقی می باشد: اول اینکه شاگردان برای مبادرت و یافتن عاملیت در تعاملات معلم محور به چه چیزی نیاز دارند؟ و دوم، معلمین چگونه می توانند به شاگردان در رسیدن به این هدف کمک کنند؟ گفتمان کاوی تعاملات کلاسی یک معلم در خلال مرور تکالیف نشان داد که چگونه به کارگیری زمان انتظار مبسوط به یکی از شاگردان فضای تعاملی لازم را برای مبادرت و طرح پرسش ایجاد کرد. علاوه بر این، استفاده مداوم معلم از زمان انتظار مبسوط پس از مبادرت شاگرد، فرصت را برای سایر شاگردان به منظور مشارکت و مذاکره در تعاملی شاگرد محور پدید آورد. گزیده هایی از تحلیل داده های این مطالعه، مدیریت و جهت دهی یادگیری توسط شاگردان را به تصویر می کشد.
