هدف این پژوهش بررسی تاثیر یادگیری تلفیقی و استفاده از نرم افزارهای چند رسانه ای بر توانایی به خاطر سپاری کلمات بوسیله ی دانشجویان انگلیسی برای اهداف خاص می باشد. به همین منظور 120 زبان آموز رشته ی پزشکی به دو گروه آزمایشی و کنترل تقسیم شدند. کلمه ها به کمک نرم افزارهای چند رسانه ای به گروه آزمایشی تدریس شد در حالی که آموزش کلمات برای گروه کنترل با روش های سنتی صورت پذیرفت. جمع آوری اطلاعات بوسیله ی پس آزمون و نظارت بر کلاس ها انجام شد. نتیجه ی بررسی ها نشان دهنده ی اختلاف زیاد بین یادگیری کلمات جدید توسط این دو گروه بوده است. به علاوه، یادگیری از طریق تکنولوژی سبب مشارکت بیشتر زبان آموزان در فعالیت های کلاسی شد. با توجه به نتایج این تحقیق، پیشنهاداتی جهت چگونگی استفاده ی موثرتر از این نرم افزارها در کلاس های زبان انگلیسی برای اهداف خاص در ایران بیان شده است.

Teacher questions are claimed to be constitutive of classroom interaction because of their crucial role both in the construction of knowledge and the organization of classroom proceedings (Dalton Puffer, 2007). Most of previous research on teachers’ questions mainly focused on identifying and discovering different question types believed to be helpful in creating the opportunities for learners’ interactions. Drawing on conversation analysis through adopting socio-cultural perspective, this study, however, aims to examine how EFL teachers manage understanding-check questions in their talk-in-interaction. For this purpose, six EFL teachers’ discursive classroom practices were observed, video-recorded, and transcribed line-by-line in its entirety. Through the microanalysis of the transcribed data, our findings suggest that EFL teachers vary in their management of understanding-check questions and the teachers’ understanding-check questions tend to serve different functions in the different micro-contexts identified. Three major sequential environments emerged to feature understanding-check questions in this study: Activity-boundary environment, post-instruction environment and within-activity environment. The findings of the study indicate that understanding-check questions at activity boundary environment are designed to accomplish dual functions, however those launched in post-instruction and within-activity environments maintain a singular focus on ensuring absolute understanding of the just-given explanation or instruction.

A long-standing debate among the vocabulary researchers is the depth of processing to learn vocabulary. This paper is a quantitative research which considers a revision in the “involvement load hypothesis” proposed by Laufer and Hulstijn in 2001. It investigates the role of proficiency and evaluation in this hypothesis in order to better reveal its potential contribution to vocabulary learning. It was based on task-induced involvementthat comparesdifferent tasks in incidental vocabulary acquisition in EFL context. The participants were 66 learners fromtwo different English institutes who were classified into two major high and low proficient groups based on Nelson Proficiency Test. The participants in each group were randomly assigned to three tasks prepared to compare“moderate”, “strong”, and “no evaluation” in involvement load hypothesis.The “strong evaluation”subgroup (making original sentences) in low proficiency supported Laufer and Hulstijn’s hypothesis and yielded better retention of the target words. The study suggests that the level of proficiency and evaluation in task induced involvementneeds reconsideration. The results have implications for language teachers, materials developers, and syllabus designers.
