Research on the effect of implicit and explicit instruction on developing learners’ explicit knowledge by the use of measures of explicit knowledge abounds in the literature. However, measuring learners’ implicit knowledge employing fine-grained measures has rarely been the concern of researchers in the field. Therefore, the present study is an attempt to scrutinize the effectiveness of implicit and explicit instruction through administering a Word Monitoring Task (WMT), as a more valid psycholinguistic measure of implicit knowledge. The necessary data were collected from 47 pre-intermediate participants in three different groups, i.e., (1) the implicit group received textually enhanced texts of verb complementation, (2) the explicit group was presented with metalinguistic explanations and examples of the target feature, and (3) the control group was deprived of any instruction. The results of the mixed between-within subjects ANOVA revealed that although both implicit and explicit instructions facilitated the development of the implicit knowledge of the target feature, the learners in the explicit group outperformed their counterparts in the implicit and the control groups in both the immediate and delayed post-tests. Moreover, the results indicated more durable effects of implicit instruction compared with those of explicit instruction. Overall, the findings provided evidence for the superiority of explicit instruction and the long-term effect of implicit instruction in developing relevant knowledge of verb complementation. The findings of the study can benefit both teachers and learners in developing teaching/learning strategies to improve and facilitate the grasp of both explicit and implicit knowledge.

Code-switching (CS), an alternation between two or more languages or language varieties, has long been researched in language education. A great number of studies by applied linguists have explored the reasons for, and the potential usages of code-switching in foreign language education over the past years. This study explores the perceptions of English language learners across various proficiency levels concerning teachers’ use of CS, in this case Farsi in English classrooms. It also examines the roles and functions of CS in the classroom. Fifty teachers and 105 language learners from University of Tehran Language Center (UTLC) in Tehran, Iran were involved in this study. The necessary data were obtained through questionnaires. The results suggested that the Elementary (EL) learners seem to benefit from the teachers' use of first language in class, whereas English-only classroom is preferred by Intermediate (IN) and Upper Intermediate (UI) ones. It was also revealed that maximum exposure of the learners to the target language seems necessary. The results suggest that, concerning the learners' levels (EL, IN and UI), teachers’ and learners’ Code Switching can work as a useful language teaching strategy. The findings of this study can have implications for English as a Foreign Language (EFL) classrooms and can be used by language teachers.

The current study used Structural Equation Modeling (SEM) as a statistical technique to test a hypothesized mediating model to uncover the underlying relationship between the L2 motivational self-system, L2 anxiety, and L2 willingness to communicate (L2 WTC). This study is significant because it considers the unique experiences of English as a foreign language (EFL) learner in the era of globalization by incorporating the L2 motivational self-system. The mediating effect of L2 anxiety was also accounted for, providing a deeper understanding of how emotional factors influence L2 WTC. The data were collected through a questionnaire administered to 260 students at six public universities in China. The results showed that (a) two subcomponents of the L2 motivational self-system (ideal L2 self and L2 learning experience) were positive predictors to L2 WTC; (b) the higher the degree to which learners were motivated by their ought-to L2 self, the higher the anxiety of English learning; and (c) L2 anxiety had a suppressing effect between the L2 motivational self-system and L2 WTC. Specifically, L2 anxiety weakens the direct positive effect of the L2 motivational self-system on L2 WTC, leading to a decrease in L2 WTC. Pedagogical implications and future research directions were also addressed.
