explicit knowledge

This study aimed to investigate the effects of Systemic Theoretical Instruction (STI), grounded in Socio-cultural Theory and proposed by Gal’perin, on developing Iranian EFL learners’ knowledge of English tense-aspect system. To this end, two low-intermediate classes, including 24 and 21 language learners aged between 12-19, were taught the distinction between simple past and present perfect tense through STI and traditional method of grammar instruction. The learners sat for a pretest one week before the treatment and an immediate and delayed posttest, one and three weeks after the instruction, respectively. The tests included binary-choice and gap-filling items to evaluate the learners’ explicit knowledge of the target tense-aspect pairings and elicited imitation test items to check their implicit knowledge. The results obtained from a series of independent and paired-sample t-tests revealed a significant improvement for both groups in the immediate posttest both in terms of the entire test and its subcomponents suggesting that both types of instruction were effective in improving the learners’ implicit and explicit knowledge of the target forms in the short term. However, the significant outperformance of the STI group compared to the traditional group implied the superiority of this method. Moreover, the STI group generally outperformed the traditional group in the delayed posttest indicating the possibility of having a more lasting effect on developing learners’ knowledge when compared to the traditional method. These findings can have significant implications for teachers and materials developers in practicing the assumptions of more innovative approaches such as STI.

In the contemporary era man has become much focused on implication of technology in every sector associated with human development. Knowledge being indispensable center of attention attracts the interest of the researchers to deal with its management from generation to dissemination and ultimately to proper use especially in the field of Science and Technology. A Knowledge Management System (KMS) being an amalgamation of content, experience, and process management; take care of management of knowledge as well as enabling its free flow amongst the employees working in an organization for a common goal. Therefore, the paper is an effort to discuss the concept of Knowledge Management along with a detailed theoretical framework for developing a KM System for any knowledge dealing enterprise. The study can be much helpful which acts as a torch bearer concept for all those organizations especially research institutes that are planning for implementation of such Systems hence lessen their efforts and time.

The neurolinguistic approach (NLA) nests the claim that both internal and external grammars (i.e., implicit and explicit grammar knowledge) develop through an intensive orality-based pedagogy. The present study put this claim to the test focusing on Iranian English language learners’ development of implicit and explicit knowledge of definite and indefinite English articles (EAs). Forty-three Iranian English language learners constituting 2 intact lower-intermediate classes were randomly assigned to a control group (CG; N = 20) and an experimental group (EG; N = 23). EG underwent four 1.5-hr project-based sessions of NLA-based instruction on definite and indefinite EAs. Each session began and ended with authentic oral practice of the structure under study. There was (a) a paragraph reading phase followed by rule induction and (b) a writing phase in between the two oral practice phases. CG was presented with reading texts (amply instantiating EAs), rule explanation, and communicative tasks. A timed grammaticality judgment test and an EA-focused oral proficiency interview were employed to estimate the participants’ implicit knowledge, and an untimed grammaticality judgment test and a metalinguistic knowledge test were deployed to measure their explicit knowledge. ANOVA results showed (a) EG’s development of implicit and explicit knowledge of EAs, but CG’s development of only explicit knowledge of EAs, and (b) EG’s significantly greater gain in both knowledge types. The findings reveal NLA’s potential for the development of both types of knowledge concerning definite and indefinite EAs, and have implications for the intensive instruction of knotty structures for low proficiency L2 learners.
