Despite the importance of hedging in academic productions, its use in different disciplines and genres has been given little attention (Hyland, 1998; Crystal, 1995). More precisely, the role of different genders as contributors to this social phenomenon (i.e., research articles) has been taken as neutral, as if gender is inconsequential in identity construction. The studies done in English suggest that females’ language is proportionately more hedged. So hedging has been claimed to be a strategy that is used mostly by female writers than male writers. To examine the role of gender in text construction, we investigated the linguistic realizations of the identities reflected in male and female authors’ preferences for hedging words in the research articles in applied linguistics. To this end, 130 single-authored research articles written in the field of applied linguistics were examined. The results revealed significant differences between two sets of articles in using hedges. Statistical analysis revealed that female authors’ articles were significantly (i.e., p-value of 0.000) more hedged as compared with those of males. Furthermore, it is suggested that the hedging words that are used in these articles could be used as an index through which gender of the author is identified.

In response to the increasing interest in and need for a practical brief measure in language testing, this study explored the properties of an offline short-form test (OSF) versus a conventional lengthy test. From the total of 98 vocabulary items pooled from the Iranian National University Entrance Exams, 60 items were selected for the conventional test (CT). To build the OSF, we created an item bank by examining the item response theory (IRT) parameter estimates. Data for the IRT calibration included the responses of 774,258 examinees. Upon the results of the item calibration, 43 items with the highest discrimination power and minimal guessing values from different levels of ability were selected for the item bank. Then, using the responses of 253 EFL learners, we compared the measurement properties of the OSF scores with those of the CT scores in terms of the score precision, score comparability, and consistency of classification decisions. The results revealed that although the OSF generally did not achieve the same level of measurement precision as the CT, it still achieved a desired level of precision while lessening the negative effects of a lengthy test. The results also signified an excellent degree of correspondence between OSF and CT scores and classification results. In all, findings suggest that OSF can stand as a reasonable alternative for a longer test, especially when conditions dictate that a very short test be used.

این مطالعه به بررسی تاثیر استفاده از دو نوع مواد اموزشی واقعی با موضوع اشنا ولی متفاوت از لحاظ ساختار بلاغی بر کیفیت شنیداری زبان آموزان سطح بالای ایرانی می پردازد. این مواد از لحاظ استدلال و منطق بیانی متفاوت هستند. براساس عملکرد زبان آموزان بر امتحان تعیین سطح فاولر و کو (1976) تعداد 60 نفر انتخاب شدند. پس از آن یک تست محقق – ساخت که دو نوع ساختار بلاغی توضیحی و مباحثه ای برای دو گروه اجرا شد. نتیجه نشان داد که شناخت موضوع به تنهایی تاثیر مهمی بر عملکرد زبان آموزان نداشته است هرچند عملکرد انها بر تست های توضیحی نسبت به مباحثه ای بهتر بود. به نظر می رسد که دانش کلی و مبهم به تنهایی کافی نیست و عملکرد ضعیف انها بیشتر مربوط به سختی ساختارهای بلاغی از لحاظ شناختی و زبانی بود. برداشت اصلی از ین موضوع می تواند این باشد که زبان آموزان سطح بالای ایرانی نیاز به شناختن این نوع ساختارها هم از لحاظ موضوعی و هم از لحاظ ساختار زبانی، اجتماعی و فرهنگی دارند. بعلاوه موضوع تعیین سطح زبانی مثلا به عنوان سطح بالا می بایست برای تک تک مهارت های زبانی در مقایسه با سطح کلی به گونه ای دیگر تعریف شود.
