The present study sets out to examine whether and how task structure affects the number and type of vague expressions used by a group of higher intermediate EFL learners. The participants were 50 Iranian EFL learners from 6 intact classes, all native speakers of Persian with limited opportunity to communicate with native speakers of English, and…

In the present cross-linguistic study two experiments were conducted to investigate the effects of age and linguistic background on response tendencies of preschoolers toward forced-choice questions. A total of 163 2- to 5-year-old children, including 63 Persian speakers, 57 Kurdish speakers and 43 English speakers, were asked a set of…

This study aimed at examining the possible effects of teacher motivational practices and student demotivation on the way Iranian English as a Foreign Language (EFL) learners produce request and refusal speech acts.

The current research study was conducted to examine the impacts of focused and unfocused audio-appended reading tasks on female EFL learners' acquisition of a rule-bound structure (passive voice) and a non-rule-bound structure (prepositions). The participants of this study involved ninety intermediate female English learners. They were assigned…

Repetitive articulatory rate or Oral Diadochokinesis (oral-DDK) shows a guideline for appraisal and diagnosis of subjects with oral-motor disorder. Traditionally, meaningless words repetition has been utilized in this task and preschool children have challenges with them. Therefore, we aimed to determine some meaningful words in order to test…

Exploring opportunities by which learners can internalize new knowledge and consolidate existing knowledge has long been a point of interest in English as a foreign language research. This study investigated how meta-talk opportunities on discourse markers created by four task types including text reconstruction, dictogloss, translation and jigsaw…

This study investigated the effect of dynamic Assessment (DA) on the acquisition of L2 grammar by EFL learners. The focus was on teaching Conditional Type II, or Unreal Conditional, which is a difficult structure for language learners to acquire. To this end, two intact classes of intermediate EFL learners, each consisting of 23 male students were…

The present study investigates the impact of Task-Based Language Teaching (TBLT) on Iranian EFL learners' reading comprehension performance. Seventy participants were assigned randomly to the experimental and control groups. Having instructed the two groups with the same texts but different task types and activities (i.e., tasks in 4 types) during…

Drawing on sociocultural theory, and a large number of empirical studies conducted on the effectiveness of scaffolding on second or foreign language learning, the authors investigated the application of different forms of scaffolding to improve listening comprehension of the Iranian intermediate English as a foreign language (EFL) learners. To…

This research sought to investigate the effect of the effect of task-based language teaching on motivation and grammatical achievement of EFL junior high school students of Ahvaz. To fulfill the objectives of the study a Homogeneity test (Oxford Quick Placement Test) was administered among 100 students at the junior high school and finally 80…

Vocabulary development is an essential goal in any language teaching program, and considering the multidimensional nature of this construct, achieving this goal needs effective assessment of all dimensions of word knowledge, i.e. breadth, depth and accessibility of word knowledge. Most of the current vocabulary assessment tools measure the breadth…

This study investigates the relative effectiveness of four types of input-enhanced instruction on the development of Iranian EFL learners' production of pragmatically appropriate and grammatically accurate suggestions. Over a 16-week course, input delivered through video clips was enhanced differently in four intact classes: (1) metapragmatic…

The current research was an attempt to explore the washback impact of task-based instruction (TBI) on EFL Iranian learners' vocabulary development. To this end, conducting an Oxford Placement Test (OPT), 30 out of 72 EFL Iranian learners studying in an English language institute, were randomly selected. Then, they were assigned to experimental (N…

Task-based planning can be conceptualized as the opportunity to work out task performance before the actual performance. It allows learners to process the content and language of their planned production at a deeper and more meaningful level. In the face of the wide range of research conducted on the effects of pre-task planning on L2 production,…

The study investigated the effect of problem-based learning through cognition-based tasks on speaking proficiency of Iranian intermediate EFL learners in comparison to the effect of objective-based tasks. To this end, a true experimental research design was employed. Ninety five (N = 95) language learners studying at a language institute in the…
