Face-to-face human interaction is divided into "focused" and "unfocused" types. Unfocused interaction often conveys important content and context information and contributes to group cohesiveness and effectiveness. Research in Computer Mediated Communication (CMC) and Computer Supported Collaborative Work (CSCW) is also concerned with human interaction. CMC tools, such as electronic mail, and C...

Considering the significance of corrective feedback and its effect on L2 vocabulary building, this study aimed to investigate extent which direct (DCF) metalinguistic (MCF) could contribute use appropriate formal written words among Arabic learners English. A writing test (IELTS Task 2) as a pre post-test was administered gauge participants’ (N= 96) lexical resources. The sample randomly divide...

In order to improve resolution of ultrasonic imaging, high frequency scanners which are employed in the range 20 MHZ to 50 MHz are needed. As a result, it is critical to obtain data on ultrasonic scattering and attenuation in this frequency range. At these high frequencies, it is not feasible to make scattering measurements with unfocused transducers; therefore focused transducers are needed. U...

Corrective feedback (CF) and its different types have long absorbed many scholars and practitioners. As Ellis (2009) mentioned some experimental studies need to be carefully designed to discover the relative effectiveness of each of these CF techniques. The goal of this qualitative study was to discover whether the employment of different CF strategies could bring about an attitudinal shift. To...

This study compared the effects of computer-mediated (CM) versus pen-and-paper (P&P) writing on written accuracy and feedback processing in tasks rewritten collaboratively following a pedagogical treatment two intact authentic classrooms. The involved 32 secondary education low-proficiency English-as-a-foreign-language (EFL) learners descriptive texts receiving in-class training identificat...
