از آنجایی که تحقیقات قابل توجهی بیان کننده نقش مهم حافظه کاری در فراگیری زبان اول می باشد، تحقیقات بر روی چنین نقشی از حافظه کاری در زبان خارجی به عنوان یک حوضه تحقیقاتی جدی، در حال وقوع است. در تحقیق حاضر، نقش حافظه کاری در توانایی خواندن در زبان خارجی مورد بررسی قرار گرفت. بدین منظور، ٥٥ نفر زبان آموز در سه سطح مهارت زبانی مبتدی، متوسط و پیشرفته از یک موسسه خصوصی زبان در این تحقیق شرکت کردند. از کلیه این افراد دو تست حافظه که شامل یک تست تعیین ظرفیت حافظه کاری از طریق خواندن و یک تست تعیین ظرفیت حافظه کوتاه مدت واجی گرفته شد. از شرکت کننده گان در تحقیق همچنین خواسته شد که در یک تست درک مطلب که شامل خواندن دو متن و پاسخگویی به سوالات آن بود شرکت کنند. سپس از عملیات آماری رگرسیون استفاده شد که مشخص شود آیا رابطه ی معنا داری بین توانایی حافظه و توانایی خواندن وجود دارد یا خیر. نتایج این تحقیق بیان کننده ی رابطه معنا داری بین توانایی حافظه کاری و توانایی خواندن فقط در سطح مبتدی بود که دلایل احتمالی آن در این تحقیق مورد بحث و بررسی قرار می گیرد.

در این تحقیق ابتدا حافظه ی کاری و مدل پیشنهادی آن توصیف می گردد. سپس طرزساخت یک تست حافظه ی کاری به همراه تشریح کامل آزمایش هایی که روی آن صورت گرفته ارائه می گردد. به طور دقیق تر، این تست شامل 64 جمله فارسی می باشد که با ویژگی های خاصی توسط یک کارشناس زبان فارسی تهیه و سپس بر روی سه دسته زبان آموزکه جمعا 74 نفر بودند امتحان شد و نواقص آن طی این سه مرحله بر طرف شد. این تست نهایتا در یک تحقیق بزرگ، جهت اندازه گیری ظرفیت حافظه ی 140 نفر زبان آموز به کار گرفته شد. نتایج تحلیل عناصر تست، پایایی 840 0/ و 7900/ را نشان داد. این بدان مفهوم است که تست ساخته شده قابل اعتماد بوده و می تواند در تحقیقات دیگر مورد استفاده قرار گیرد. همچنین محققان زبانهای دیگر می توانند از فرایند طی شده در این تحقیق جهت تهیه تست حافظه در زبان خود پیروی کنند.

This study aimed at gaining insights into students’ attitudes in the learning English using the Smart Board or Interactive White Board (IWB) technology in EFL classrooms. The main goal of this paper is to evaluate students’ attitudes towards the use of Smart Board as an instructional tool on student motivation, participation, interaction and retention for learning English in Iranian schools. To achieve this aim, an observation was carried out during lessons in the classroom by the researcher. A questionnaire consisting of 20 questions was also developed by the researcher based on an extensive literature review as well as related instructional theories. The researcher also conducted an interview to find the effect of Smart Boards on student motivation, participation, interaction and retention of information in English classrooms. Analysis of these three instruments yielded patterns of responses concerning how Smart Board or IWB technology can motivate the students and increase their participation in classroom. The results of this study also indicate that students interact more in classrooms where technology is used effectively. Finally, it was found that Smart Boards enhance students' retention of information and learning process in EFL classrooms. The findings of the study will carry important implications for students, language instructors, and administrators as well.

Mastery of English phrasal verbs is regarded as a stumbling block for English language learners, even at advanced levels. Possible sources of difficulty can be a lack of clear meaning and the random nature of particles. The lack of an organized approach to present phrasal verbs to the learners might be a factor that could exacerbate the situation of learning them. This study takes this issue as its point of departure. It investigates whether employing radial categories, conceptual categories with one prototypical concept and some peripheral members that are organized around it, is influential in the learning and long-term retention of these verbs. Moreover, the effect of employing radial categories to teach PVs on learners' cognitive load is investigated. For this purpose, 60 intermediate high school students in 10th and 11th grade were assigned to two groups, one experimental and one control group, each containing 30 students. The study results indicated that the experimental group learners who were taught phrasal verbs using radial categories outperformed control group learners who were taught using a traditional approach. This result suggests that radial categories may help facilitate learning phrasal verbs.

Given the seemingly important link between children’s working memory (WM) and their scholastic performance, it would be a worthwhile research enquiry to explore language learning as one potential way to improve WM. To this end, the present study examined the impact of two language teaching paradigms, namely, Presentation-Practice-Production (PPP) and Total Physical Response (TPR), on children’s WM over time. Seventy participants, aged 8 to 9 years, were administered tests of phonological, visuo-spatial sketchpad and central executive components, and made up TPR, PPP and control groups for a period of three months. Then, a posttest and a delayed posttest were administered to identify whether the treatments led to significant improvements. The results of the 3 WM measures indicated that the 2 interventions led to certain improvements. Whereas TPR led to significant improvements in the central executive, PPP produced significantly higher gains in phonological memory over time. Neither treatment induced any positive impact on the visuospatial sketchpad. The results lend evidence to the trainability of WM. It is also suggested that language learning experiences have long-lasting repercussions and that each language learning experience can impact certain components of WM.
