This study shed light on the effects of four modes of vocabulary instruction, i.e., extended audio glossing, lexical inferencing, lexical translation, and frequency manipulation of input on the learning of lexical collocations by Iranian intermediate EFL learners. In so doing, 80 L1 Persian EFL students were divided into four 20-participant…

This study investigates the effects of input-based and output-based instructions on the acquisition of second language (L2) request modifiers. Four intact classes were randomly assigned to textual enhancement (TE), input flooding (IF), output-based instruction (OI), and control (CO) groups. The TE group watched some captioned videos on requests…

The present quantitatively-driven mixed methods study aimed at exploring the effect of musical input as a mode on intermediate L2 learners' knowledge and retention of difficult words. The data were collected in two phases. In the experimental phase, quantitative data were collected from 40 learners. An innovative method was used for the purpose of…

The present study examined the effect of different vocabulary instruction methods on EFL learners' vocabulary learning and retention. Elementary and advanced EFL learners (N = 120), selected through convenience sampling, were randomly assigned to three conditions (i.e., six groups for the two levels). The learners in the explicit group received…

The present research sought to explore the combined contribution of input flooding, visual input enhancement, and consciousness-raising tasks on noticing and intake of the present perfect tense among Iranian EFL learners. Using a nonrandomized control group pretest-posttest design, the researchers attempted to see if instruction could enhance the…

The present study sought to investigate the effects of meaning-focused input (MFI) and meaning-focused output (MFO) activities on willingness to communicate (WTC) of English as a Foreign Language (EFL) learners. The study aimed at exploring learners' perceptions towards the efficacy of MFO and MFI activities for developing WTC. The participants of…

The present study aimed at investigating the effects of scaffolding strategies using input and output-oriented tasks on Iranian EFL learners' receptive and productive knowledge of lexical collocations. For this purpose, 540 adult intermediate-level EFL learners--both male and female--were selected and divided into six experimental groups; three…

The present study examined two input modification techniques, namely lexical elaboration (LE) and typographical enhancement (TE), and the combination of these two (LE & TE) to seek the difference among them as far as incidental vocabulary learning through reading is concerned. Ninety six Iranian EFL students whose reading proficiency was at…

The purpose of this study was to find out, whether three methods of presenting input, were effective in relation to language aptitude. Persian-speaking learners of English were provided with 20 grammatical collocations (verb-preposition collocations) embedded in authentic passages, lexically/grammatically elaborated passages, and…
