This meta-analysis is an investigation into the impressibility of two dimensions of the speaking skill, namely accuracy and fluency, in relation to the experimented treatments among Iranian EFL undergraduates. Having surveyed a collected bank of 74 research reports, the relationships among the variables in the 14 included studies were examined. More specifically, the analysis involved a statist...

This study investigated the effects of planned focus-on-form instruction (pFFI) on developing oral grammatical accuracy in Iranian English EFL learners. To this end, 60 lower-intermediate EFL learners studying English in a private English language institute in Tehran, Iran, were randomly assigned to two classes. Both classes received a task-based instruction on grammatical points elicited in or...

Objectives: Presence/absence of cervical lymph node metastasis plays a critical role in prognosis and survival of patients with oral squamous cell carcinoma (SCC). This study was designed to assess the diagnostic accuracy of computed tomography (CT) scan for detection of cervical lymph node metastasis in oral SCC in comparison with histopathological analysis after neck dissection Methods: In...

background radiographs play an integral role in the assessment of periodontal disease. in recent years, advent of digital imaging has revolutionized radiology in dentistry. patients and methods in this diagnostic accuracy study, 48 inter proximal surfaces were evaluated in eight patients. these patients had alveolar bone loss in anterior regions because of periodontitis. intraoral (parallel per...

Researchers have extensively compared different L2 learning contexts, such as EFL versus study-abroad, for their impacts on oral production; however, scant attention, if any, has been paid to comparing EFL settings in terms of input factors such as textbooks, amount of contacts in L2, and teachers. Accordingly, the effects of these factors on the oral production skills were investigated in this...

o bjectives : dental caries are common and have a high incidence among populations. radiographs are essential for detecting proximal caries. the best technique should be recognized for accurate detection of caries. the aim of this study was to compare the accuracy of detection of proximal caries using intra oral bitewing, extra oral bitewing, improved interproximal panoramic, improved orthogona...

This study set out to explore the impact of three levels of task planning on the accuracy of task-based oral performance with narrative task types among sixty Iranian sophomores majoring in Teaching English as a Foreign Language (TEFL) at Islamic Azad University – Tabriz Branch. It was hypothesized that simultaneous pre-task/on-line planning would lead to more accurate performance. To test the ...

Background: Medical error is defined as an adverse event caused by medical management, which can be prevented. The aim of this study was to investigate the accuracy of diagnosis of oral and maxillofacial diseases made by health care practitioners. Methods: A descriptive cross sectional study was done between Apr. 2009 and Mar.2010. 372 Patients with oral and maxillofacial lesions who had referr...

and Applied Analysis 3

Among the major issues raised by classroom SLA researchers is the debate on the degree to which teacher’s or learner’s attention should be directed to linguistic features. However, one of the relevant variables in corrective feedback studies which seem to be less operationalized is the differential impact of different types of feedback on the accuracy of the oral performance of the participants...
