Speaking has been considered one of the most important skills in second language teaching and assessment. However, to date there has not been a clear definition of speaking ability. The present study attempts to examine what it means to be able to speak a second language using a newly designed computer-delivered speaking test. The test was created based on a theoretical definition of speaking a...
Reticence is a common problem faced by ESL/EFL teachers in classrooms, especially in those with mainly Asian students. The willingness to communicate model of MacIntyre, Clement, Dörnyei, and Noels (1998. ‘Conceptualizing willingness to communicate in a L2: a situational model of L2 confidence and affiliation’. The Modern Language Journal 82/4: 545–62.) postulates that willingness to speak is d...
Shelf life prediction for liquid fuels depends on a reliable and efficient accelerated ageing method. Most of the available researches in this area are limited to isothermal ageing. Therefore, these isothermal ageing methods are not capable to predict shelf life for fuels at non-isothermal ageing conditions. In the previous work, a new approach called reaction severity index was proposed for t...
this research concentrates on the lithostratigraphy, biostratigraphy, microfacies and sedimentary environment of the asmari and gachsaran formations at southwest firuzabad. the thickness of the studied section in all 608.95 meters that 220.8 meters belong to the asmari formation and 387.95 meters belong to the gachsaran formation (champe and mol members). in the study area, the asmari formation...
It is, thus, not surprising that English education has gained more attention than ever and there also has been a growing amount of interest in learning English online. Although there are a good number of ESL/EFL E-learning websites available, many of them are poorly designed technologically and/or pedagogically. It is true that technology, such as human-computer interaction (HCI) and computer-m...
This study considers the ongoing “grammar correction debate” in second language writing by examining how a focus on formal accuracy would affect the revising processes of ESL writers and the students’ written products. A case study approach was used to find out how two ESL students would respond in the two different rewriting situations: (a) when there is no explicit expectation for them to pro...
چکیده شیل های ارغوانی به عنوان یک عضو رسمی در قاعده سازند پابده در نقاط متعددی از زاگرس رخنمون دارند. به منظور بررسی چینه¬شناسی و محیط رسوبی شیل¬های ارغوانی در بخش شمالی حوضه زاگرس، 4 برش در استان ایلام در مناطق پاریاب، ملکشاهی، بیشه¬دراز و دره شهر به همراه برش الگوی سازند پابده واقع در تاقدیس گورپی در شرق استان خوزستان برداشت و مورد مطالعه قرار گرفت. در مجموع از این برش¬ها 507 اسلاید پالینول...
Learning new sounds in a second language requires the acquisition of new motor routines and new sensorimotor planning systems needed to ensure coordination. Auditory feedback is an important part of the planning and control system required for fluent speech production. ESL vowel production was studied using a real-time formant perturbation technique to modify auditory feedback. Three groups of ...
One of the difficulties of the liquid fuels is theirs shelf life because these fuels like other chemical materials become off spec after a period of time due to the tendency to the destructive reactions. This variation in fuel spec affects the chemical and physical properties of fuel and therefore the combustion performance. This subject is significant because of need to long time storage of fu...
There are many efforts to utilize the mobile phone as a computing platform in developing regions of the world. One effective approach is to build educational games for children in these regions. Existing games in this space are typically single-player affairs, devoid of the possibly beneficial element of collaboration between multiple learners. We seek to explore the feasibility of creating mul...
