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…

Derivational knowledge is associated with writing and speaking skills. These skills are essential for EFL students who express themselves in oral presentations or written assignments. Therefore, diagnostic measurement of productive derivational knowledge is of vital importance, especially in regard to the most frequent 1,000 word families that…

Collocations are one of the areas that create problems for EFL learners. Iranian EFL learners like other EFL learners encounter serious problems in producing collocations. The current study is an attempt to examine the Iranian EFL learners' ability to produce English collocations. It also attempts to identify the strategies that they usually adopt…

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…

The notion of "textuality" encouraged Halliday and Hasan in 1976 to present their model of discourse analysis through raising questions about whether "cohesion" was a semantic concept or a structural relation, whether a text was a structural unit or not or even if there were semantic or structural relationships within a text.…

This study aims to clearly diagnose EFL "students' writing strengths and weaknesses." I adapted a diagnostic framework which comprises multiple writing components associated with three main dimensions of second language writing. The essays of 304 English learners who enrolled in an English language program were double-rated by 13…

The present study attempted to investigate the effects of audio input enhancement on EFL learners' retention of intensifiers. To this end, two research questions were formulated. In order to address these research questions, this study attempted to reject two null hypotheses. Pretest-posttest control group quasi-experimental design was employed to…

Focus on form instruction is a kind of instruction that draws students, attention to linguistic elements as they arise incidentally in meaning based instruction. There are different types of focus on form instruction. The present study was designed to investigate the effect of incidental focus on form on grammatical accuracy among Iranian L2…

Han's (2009, 2013) selective fossilization hypothesis (SFH) claims that L1 markedness and L2 input robustness determine the fossilizability (and learnability) of an L2 feature. To test the validity of the model, a pseudo-longitudinal study was designed in which the errors in the argumentative essays of 52 Iranian EFL learners were identified and…

This study investigates the effects of cross-linguistic consciousness-raising through comparing and contrasting learners' L1 (Persian) and L2 (English) on their L2 written performance. To do this, sixty intermediate language learners, both male and female, learning English at two private institutes in Yasuj, Iran, were chosen as the participants…

This study investigates the Iranian EFL learners' Knowledge of Lexical Collocation at three academic levels: freshmen, sophomores, and juniors. The participants were forty three English majors doing their B.A. in English Translation studies in Chabahar Maritime University. They took a 50-item fill-in-the-blank test of lexical collocations. The…

This study investigated the frequency of the grammatical errors related to the four categories of preposition, relative pronoun, article, and tense using the translation task. In addition, the frequencies of these grammatical errors in different categories and in each category were examined. The quantitative component of the study further looked…

This study investigated the developmental and fossilized prepositional errors in Persian EFL learners' compositions at three levels of proficiency; participants were divided into lower-intermediate, upper-intermediate, and advanced levels. For each participant, four compositions were collected, and after identifying the prepositional errors for…
