cognitive grammar

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 structures. To this end, over the course of eight weeks 28 third grade middle school students (14 years old) received the concepts in the CBI framework and 30 third grade middle school students received a traditional type of instruction. There were three sets of data including definition of the concepts of tense and aspect before and after CBI, concept verbalization data during CBI, written discourse performance plus responses to a set of grammatical questions before and after CBI. It was found that although both groups improved significantly after receiving the instruction, the students who received CBI performed significantly better than those in the traditional group. The students who received CBI also produced a significant definition of the concepts and their written discourse performance and responses to the grammatical questions improved after CBI. The result provides insight into the application of scientific concepts in L2 instruction.

This paper is an attempt to explore the prepositions used to encode the agent in Persian passive constructions. According to Givón (1983) the main function of the passive constructions is to defocus the agent. As the general trend in Persian is to omit this defocused agent, we will stylistically divide the passive constructions into two main sub branches, namely unmarked and marked passives according to whether or not the agent is included. Having analyzed the prepositions using in the passive construction (e.g. t { v { ssot-e, be d { st-e, b A , { z suy-e, { z t { r { f-e, and be v { sile-y-e) a complete semantic characterization of the type of agent that normally occurs with these prepositions will be provided. The results indicate that, in contrast to some linguists who treated the prepositions in the passive construction as stylistic forms, they are not always interchangeable; in fact they are meaningful which have a prototype for the type of agent that co-occurs with them.

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.

Much research has been done on semantics of the verbal element of complex predicates (CPr), usually referred to as light verb (LV). Most researchers have confined their studies to a few limited features of light verbs. After criticizing major views proposed by scholars on the semantics of light verbs, this article presents a hypothesis on the formation of complex predicates, arguing that all of which directly or indirectly have roots in incorporation process. This process starts with a complete sentence, incorporating two elements into it and ends in eliminating other elements. Formation of each complex predicate leads to the formation of the constructional schema X+LV0 which sanctions formation of new complex predicates with the same light verb and in the same semantic field. Accordingly, the meaning of light verb in direct incorporation case is the same meaning as its heavy verb, and in indirect incorporation case is dissolved in constructional meaning of the sanctioning schema. The meaning of light verb in each of these two cases could be different and each of them is taken or similar to one of its heavy meanings. There is a third case in which the light verb plays the role of verbalizing element and makes possible for a nonverbal predicate to inflect as a verb. Thus light verbs vary from having completely schematic and non-thematic meanings to their own primary heavy meanings.
