English as a foreign language (EFL) is a global issue that extends to thousands of learners worldwide who share a similar classroom situation. However, researchers have often considered learners to have homogeneous linguistic profiles, overlooking the fact that EFL classrooms in primary and secondary education include learners with different…

Vocabulary development is an essential goal in any language teaching program, and considering the multidimensional nature of this construct, achieving this goal needs effective assessment of all dimensions of word knowledge, i.e. breadth, depth and accessibility of word knowledge. Most of the current vocabulary assessment tools measure the breadth…

The current research was an attempt to explore the washback impact of task-based instruction (TBI) on EFL Iranian learners' vocabulary development. To this end, conducting an Oxford Placement Test (OPT), 30 out of 72 EFL Iranian learners studying in an English language institute, were randomly selected. Then, they were assigned to experimental (N…

This study addressed the potential methodological issues effect of attentional condition on subsequent vocabulary development from a different perspective, which addressed several potential methodological issues of previous research that have been based on psycholinguistic notion of second language learner as a limited capacity processor. The…

This paper reports the findings of a study that investigated the effect of giving and receiving marginal L1 glosses on L2 vocabulary learning. To that end, forty nine Iranian learners of English were assigned to three different experimental conditions including marginal L1 glosses Giver (n = 17), marginal L1 glosses Receiver (n = 17), and no…

This study investigated how task-based learning (TBL) developed the verbal competence of Chinese learners of English as a foreign language (EFL) by employing qualitative and quantitative analyses. We compared the impromptu oral presentations on reading texts of 76 intermediate EFL learners given respectively in the beginning and the end of the…

The study aimed to investigate whether or not negotiation of meaning is effective in L2 vocabulary acquisition of Chinese learners of English in the classroom setting. In the study there were two experimental groups (pre-modified input and negotiation of meaning) and two control groups (pre-modified input). The four groups were required to do a…

Vocabulary knowledge influences the learners' performance so remarkably that success in all language skills is closely related to it. This vital role necessitates studies focusing on the most effective programs of teaching vocabulary. In this study, we aimed to explore the impact of static versus dynamic task type and the possible interaction with…

This study investigates the teaching of vocabulary in ESP courses within the paradigm of task-based language teaching, concentrating on Persian literature students at Birjand University in Iran.

The purpose of the present study was to investigate the L2 use rate in EFL classrooms through introducing three task conditions in learning lexical items. Data were collected from a group of freshman university students (male and female) studying in Islamic Azad university of Sabzevar, Iran (N = 73). Based on their performance on a Michigan TOEFL…

This study attempts comprehensively to investigate the effect of form versus meaning-focused tasks on the development of collocations among Iranian Intermediate EFL learners. To this end, 65 students of Mashhad High schools in Iran were selected as the participants. A general language proficiency test of Nelson (book 2, Intermediate 200A) was used…

This empirical study was undertaken to test the Involvement Load Hypothesis (Laufer and Hulstijn, 2001) by examining the impact of three tasks on vocabulary acquisition. It was designed to test and develop the involvement load hypothesis by examining the impact of different reading tasks on the L2 vocabulary acquisition. The results show that…
