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 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…

In this study, 92 Iranian intermediate EFL learners (17 to 22 years) took part in 14 sessions in which they were taught L2 vocabulary through three input enhancements, i.e., visual input enhancement, semantic input enhancement, and input flooding. In fact, the selected participants were divided into three experimental groups and one control group.…

The current study investigates the effect of massed and spaced instruction on vocabulary recall and retention. To fulfill this objective, 75 Iranian pre-intermediate EFL learners (16 to 19 years) took part in 15 sessions of 60 minutes. The participants were randomly divided into three experimental groups; a spaced distribution group (n = 25), a…

Listening has long been recognized as a challenging skill for teachers, students, and researchers working within the English as a Second Language (ESL)/English as a Foreign Language (EFL) contexts. Moreover, up until the recent past, it was the least researched of the four language skills in second language acquisition studies. One of the issues…

Computer-Assisted Pronunciation Teaching (CAPT) provides EFL teachers with more alternatives to help learners who have serious problems in learning pronunciation. CAPT also provides EFL learners with a private, stress-free environment where they can have access to an enormous amount of input and repetitive practice pronunciation at their own pace.…

Considering the vital role of comprehensible input, this study attempted to compare the effects of input with various difficulty levels on Iranian EFL learners' reading comprehension and reading motivation. To fulfil this objective, 54 Iranian pre-intermediate EFL learners were selected from two intact classes (n = 27 each). The selected…

The impact of the non-native speaker's (NNS) language proficiency on their personal teaching performance has often been an issue in TESOL teacher education programmes. To explore this issue a study was conducted to investigate the link between language teachers' language proficiency and their teaching effectiveness. Classes taught by eight NNS…

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…

This study is conducted to examine the effect of input enhancement as an implicit and consciousness-raising as an explicit method of instruction on improving grammatical and lexical collocation knowledge of Iranian EFL learners. To reach this aim, a sample of sixty participants at pre-intermediate level of English proficiency in Gorgan, Golestan,…
