Test washback is held to be complicated and multifaceted in that a host of cultural, social, individual, test, and institutional factors are involved in shaping it. Thus far, the majority of washback studies have had as their focus the role of teachers in test washback or washback to teachers. How educational environments or institutions might function in isolation or in interaction with other factors in shaping washback to the learners and test takers has not received adequate research attention. The current study examined the mediatory role of academic institutions in washback to learners' perceptions of test content and test preparation. To this aim, 86 senior English students from two universities, one a top tier and the other a low tier one, completed two questionnaires: one on test takers' preparation practices including test analysis, test taking skills, drilling target skills, and socio-affective strategies; and the other on test takers' construal of test demands and uses as well as their expectation of success on the test.  The data analyzed through partial least squares structural equation modeling revealed that a washback model based on expectancy-value theory explains a moderate amount of variance in test preparation. Further, for test takers from the low tier university, favorable perceptions of test content were associated with more value placed on test taking. However, Multi-group analysis pointed to group-invariance of the model across the two institutions, indicating a lack of strong evidence for the mediatory role of educational environments in washback to test takers’ perceptions and preparation.

This study has aimed to compare the effects of two types of form-focused instruction, i.e. de-contextualized focus-on-forms instruction versus meaning-centered contextualized focus-on-form instruction, on the development of grammatical knowledge of Iranian high-school students. Two groups of male high-school first graders participated in this study.  One group was taught through de-contextualized deductive grammatical explanation, while the other group received enhanced input and contextualized grammar instruction embedded in meaning-centered activity based on dialogs. The results indicated that de-contextualized instruction as it is normally practiced in high-school contexts failed to promote successful use of the auxiliaries <em>do, does, </em>and<em> did</em> in a written production test. In contrast, adding the design features of meaning-based contextualization and enhanced input to instruction did result in better performance on a written production grammar test involving the use of the auxiliaries under study. In the delayed posttest, contextualized meaning-based instruction appeared to have a durable effect, but the effect was not significant enough to warrant any claim for the durable superiority of this form of instruction. 

Academic discourse has always been the focus of many linguists, especially those who have been involved with English for Academic Purposes (EAP) and discourse analysis. Persuasion, as part of rhetorical structure of academic writing, is partly achieved by employing modality markers.  Adopting a descriptive design, the present study was carried out to compare the use of modality markers in terms of frequency and their categorical distribution in two academic books, written in English, in the field of Applied Linguistics by native English and non-native Iranian authors.  Quirk, Greenbaum, Leech, and Svartvik’s (1985) model of modality was employed as an analytical framework to identify the type of modal verbs. The frequency of different types of modal verbs was calculated per 100000 words and the significance of difference in their distribution was checked through Chi-square nonparametric inferential statistics. The results of the statistical analyses did not show any significant difference in the overall distribution of modality (both epistemic and root) markers.  However, significant differences were observed in the categorical distributions of modal verbs in two corpora. The results were attributed to the non-native writers’ lack of awareness of the conventional rules of English rhetoric, and the lack of explicit instruction in this field. The findings could offer pedagogical implications for those involved in syllabus design and materials development in general and English writing courses in particular.

This action research examines the concept of Willingness to Communicate (WTC) in a second language acquisition context. The researcher investigated the contributors of WTC in a foreign language classroom setting. Therefore, a multiple assignments method and sequence was applied. Participants of this study were students who matriculated in a United States (U.S.) undergraduate program, studying German at a public Midwest University. Findings of this study suggest applying various speaking activities and providing the opportunity to practice assessment-like activities prior to the evaluation, which enhanced second language WTC. In addition, the present study found three major factors that contributed to second language WTC: student preparedness, student feelings, and speaking capacity influences. Findings of this study can be implemented into any language classroom. The teaching methods and sequence of activities can be integrated into language curriculum. This study provides insight on a successful language teaching model that prepares students to engage in any oral communication with more confidence and less hesitation.
