این مقاله به مقایسه ساختار مدخل های فرهنگ ها و ساختار معنایی کلمات در مجموعه واژگانی ذهنی انسان می پردازد. ساختار مدخل را می توان به عنوان یک ساختار سلسله مراتبی کلمات چندمعنایی که بر اساس تجزیه و تحلیل متون تهیه شده است، بررسی کرد. این ساختار سلسله مراتبی در فرهنگ های گوناگون به اشکال مختلفی تجلی یافته است؛ ولی معانی گوناگون مربوط به یک کلمه چندمعنایی دارای سلسله مراتب قرارگیری ویژه خود هستند. تعیین این معانی به میزان کاربرد گویشوران بستگی دارد و معمولاً با سلسله مراتب موجود در فرهنگ های لغت مطابقت ندارد. بر پایه معانی و تصورات همگانی از کلمه форма برای پنج گروه اجتماعی نشان داده شده است که تعداد معانی پرکاربرد و سلسله مراتب آنها در مجموعه واژگان ذهنی برای گروه های اجتماعی گوناگون متفاوت است.

This meta-analysis is an investigation into the impressibility of two dimensions of the speaking skill, namely accuracy and fluency, in relation to the experimented treatments among Iranian EFL undergraduates. Having surveyed a collected bank of 74 research reports, the relationships among the variables in the 14 included studies were examined. More specifically, the analysis involved a statistical review of 67 effect sizes (at 95% CI) calculated from studies conducted between 2006 and 2016, including 890 participants. The analysis indicated that in 77% of the experimented treatments, the students performed as well as the students in the regular programs with no significant improvement in oral accuracy. The analysis also demonstrated that 63% of the treatments did not yield significant improvement in oral fluency in comparison with the regular instruction. Moreover, the synthesis of the effects of the contextual factors showed that low-level (i.e., elementary) learners experienced a better improvement in speaking performance. The analysis also revealed that, among the experimented treatments, dialogic tasks were most effective on oral accuracy while interviews were influential in promoting the students’ both oral accuracy and fluency. Finally, the quality of the study reports was analyzed and some directions for further research were suggested.

The present study attempted to discover whether there is a significant relationship between EFL teachers' critical thinking ability and their teaching success.To this end, 113 Iranian male and female English teachers were required to fill out Watson Glaser Critical Thinking Appraisal. Besides, their students were asked to answer the Characteristics of Successful EFL Teachers questionnaire. The statistical analysis of the data showed that there was a significant correlation between EFL teachers’ critical thinking skill and their teaching success. Besides, findings revealed that there was a significant difference between male and female teachers regarding their critical thinking skills, and that BA teachers differed from AS teachers with regard to critical thinking skills. More specifically, male BA teachers took the most advantages from critical thinking skills than others.  

Errors are one of the enigmatic parts in the process of foreign language (L2) learning as they are extremely versatile at each and every stage of the language learning proficiency. The present study, therefore, was an attempt to reveal Iranian EFL learners’ grammatical errors in writing at two levels of proficiency, namely lower intermediate and advanced, and then to investigate whether there was a relationship between the levels of EFL learners’ proficiency and the types of grammatical errors they committed in their scripts. The study was carried out at a private language institute in Gorgan, Iran. To this end, 60 female EFL learners (30 lower intermediate and 30 advanced females) whose age ranged between 13 and 17 participated in this study and wrote 150 word writing samples on a predetermined descriptive subject. The descriptive analyses of the data based on the scoring framework of the study demonstrated the types of grammatical errors at each level of proficiency. A Chi Square test was then run in SPSS Ver. 25 on the 16 common frequent error categories between both levels of proficiency, which verified the existence of a relationship between EFL learners’ levels of proficiency and the types of written grammatical errors they committed in their writing. The findings of the study might be of interest to EFL learners, EFL teachers, syllabus designers, and materials developers.

هدف از این کار تحقیقی بررسی افعال با ماهیت معنایی «فریب» در لهجه های گویشوران مناطق مختلف تولا است. بر همین اساس، در این مقاله برآن هستیم تا ضمن تجزیه و تحلیل معانی مختلفی که از این گونه افعال استنباط می شود، شکل و ویژگی های دستوری این گونه افعال را در هنگام کاربرد در گویش های گوناگون مردم این مناطق بررسی نماییم. این گونه افعال غالباً ماهیت معنایی منفی دارند. افعال دارای ماهیت معنایی منفی در گویش ها و لهجه ها کاربرد بیشتری دارند. این گونه افعال از نظر تقسیم بندی در زمره افعالی قرار می گیرند که بیان گر نوع رابطه و رفتار افراد نسبت به محیط اطراف هستند. این افعال از اصلی ترین عناصر فعلی تشکیل دهنده گویش های محلی محسوب می شوند. از این گونه افعال معمولاً به عنوان افعال «انسان محور» یاد می شود. مجموعه افعالی که در این کار پژوهشی بررسی و تحلیل شده اند از نظر تک واژی ریشه های گوناگونی دارند. معمولاً تک واژهای ریشه ای این گونه افعال در معنای مستقیم و اولیه خود بیان گر تأثیرگذاری و یا تأثیرپذیری فیزیکی هستند و تا حدود زیادی از نظر شکل ظاهری و همچنین از نظر ماهیت معنایی فرم واحد و یکسانی دارند که وجود گروه افعال مترادف و زایا می تواند دلیلی بر این یک سان بودن باشد.
