The present study examines the role of Gal’perin’s Concept-based Instruction (CBI) as a pedagogical approach in teaching cognitive grammar-based (CG-based) concepts of tense and aspect to EFL students. Following the sociocultural theory of L2 Acquisition (SCT), arming L2 learners with scientific concepts can lead to L2 development by deepening their understanding and raising awareness of L2 str...

This paper presents a case study in low-cost noninvasive Built-In Self Test (BIST) for RAPPID, a largescale 120,000-transistor asynchronous version of the Pentium R Pro Instruction Length Decoder, which runs at 3.6 GHz. RAPPID uses a synchronous 0.25 micron CMOS library for static and domino logic, and has no Design-for-Test hooks other than some debug features. We explore the use of Cellular A...

This quasi-experimental study examined the effects of input-based, meaning-based output (MO) and traditional instruction (TI) on EFL learners’ grammar learning. To this end, 120 junior high school students were selected from 4 intact classes. Each class was assigned to an instructional condition, that is, textual enhancement (TE), input flood (IF), MO, and TI. Before the treatment, a multiple-c...

Constructive Alignment (CA) is a pedagogical tool for designing student-centered instruction aligned to learning outcomes. Despite strong evidence that CA and are superior lecture-based pedagogy, the latter remains prevalent across higher education. This descriptive-explanatory case study ( n=20) investigates how programs of reciprocal, non-evaluative peer observation can help faculty understan...

with specific tumor markers .So, tumor markers Ca 15-3, Ca19-9, Ca 125, and CEA were fluctuated in normal ranges. Serum levels of alphafetoprotein (a-FP) were significantly elevated reaching the plateau of 392 iu/ ml (normal ranges: <9.5 iu/ml), supporting the sonographically evoked opinion of underlying malignancy. Except that AST (62 IU/L), ALT (73 IU/L) and LDH (309 IU/L) were mildly increased.

Systematic phonics instruction in first language education has recently received considerable research attention due to its critical role in facilitating phonological awareness and processing skills. However, little is known about the effects of systematic phonics instruction on foreign language reading and spelling in an EFL context. This study examined the effects of spelling-based phonics in...

the purpose of this study was to investigate the effect of call/web-based instruction on improving efl learners’ pronunciation ability. to this end, 85 students who were enrolled in a language institute in rasht were selected as subjects. these students were given the oxford placement test in order to validate their proficiency levels. they were then divided into two groups of 30 and were rando...
