تحقیق حاضر به بررسی اثرات دو نوع از انواع حاشیه نویسی تعاریف واژگان بر درک مطلب خواندن در میان دانشجویانی که در سطح متوسطی از مهارت زبانی هستند پرداخته است.بدین منظور، دو گروه آزمایشی مورد مطالعه به خواندن 10 متن آکادمیک تحت شرایط مختلف مبادرت ورزیدند. یکی از گروه ها، هنگام خواندن متن چندرسانه ای کامپیوتری، از تعاریف متنی که با اشاره گر ماوس بر صفحه نمایش ظاهر می شد استفاده کرد. گروه دیگر، هنگام خواندن متون، از تعاریف ترکیبی(متن و تصویر) که به آشکارسازی معانی کلید واژگان کمک می کرد بهره جست. گروه کنترل، در مقابل،از هیچ نوع حاشیه نویسی استفاده نکرد و تنها بر متد حدس زدن تکیه کرد. نتایج تحقیق نشان داد که گروه آزمایشی که از حاشیه نویسی ترکیبی استفاده کرده بود میانگین بالاتری را نسبت به دو گروه دیگر در آزمون درک مطلب کسب نمود. در عین حال، گروهی که از تعاریف متنی استفاده کرده بود نسبت به گروه کنترل میانگین بالاتری اخذ کرد. یک توجیه آن است که به احتمال زیاد حاشیه نویسی ترکیبی تعاریف واژگان در آشکارسازی بهتر و مؤثرتر واژگان کلیدی متن خواندن کمک بیشتری می کند که در نتیجه آن درک مطلب به نحو عمیق تری صورت می گیرد.

The present study sought to find the most frequent lexical bundles, particularly the token of the bundles, in the introduction and discussion sections of Civil Engineering research articles. It also aimed to examine the forms or types of lexical bundles found in the introduction and discussion sections of the articles. To this end, a quantitative analysis was performed on the use of two-to-five-word lexical bundles, followed by a qualitative analysis of their functions and structures based on the structural taxonomy of lexical bundles proposed by Biber, Conrad, and Cortes (2004). AntConc, as a corpus analysis tool, was employed for the extraction of lexical bundles as well as the examination of their types and tokens. Likewise, concordancers and word and keyword frequency generators were used for the analysis of word clusters and lexical bundles.   A total of 790 lexical bundles in the introduction section and 279 lexical bundles in the discussion section were analyzed based on a set of pre-established criteria (e.g., the frequency cut-off of 20 per million words) . The findings revealed that the lexical bundles consisted largely of two-word strings, and the five-word strings were the fewest. Regarding the structural classification of bundles, phrasals were the most frequent ones, whereas clausal on es were the least frequent ones. The study carries important implications, especially for materials developers and course designers who may hopefully benefit from the results in designing EAP materials finely tailored to the linguistic needs of Civil Engineering students.

This study was carried out to explore the effects of a mobile application on the learning of L2 grammar and vocabulary among Iranian intermediate EFL learners. In this research study, the target population comprised 30 male and female EFL learners who were identified at the intermediate level of language proficiency based on their performance scores on a sample copy of the Oxford Solutions Placement Test (OSPT). The participants were selected from among 40 learners who were studying EFL at Talk English Institute in Rasht, Iran. Using a digital randomizer called Super Cool Random Number Generator, the final pool of qualified participants was randomly assigned into two groups of experimental and control, each consisting of 15 learners. Next, the experimental group received treatment on their English vocabulary and grammar during a four-week period where they were assigned to learn 20 grammar and 20 vocabulary items by playing games through a mobile educational game called Elevate. The control group, on the other hand, received treatment on the same L2 grammar and vocabulary items through a conventional method (i.e., teacher-fronted instruction). Analysis of the scores obtained on a post-intervention measure of L2 grammar and vocabulary knowledge revealed that both groups made significant progress over the course of the experiment; however, the experimental group performed significantly better than those who were trained using the conventional method. The results carry the implications that mobile applications provide a more felicitous condition for expanding learners’ L2 grammar and vocabulary repertoire.
