This experimental study attempts to see whether incorporating supplemental podcasts into the blended module of second language (L2) vocabulary teaching and learning leads to better learning outcomes in comparison with other common teaching and learning methods as self-study and conventional. To that end, undergraduate students from Ahvaz Jundishapur University of Medical Sciences were summoned up via an announcement to take part in the study. Volunteers were homogenized via Vocabulary Levels Test (VLT) and were then randomly divided into three groups to learn English vocabulary items via three different scenarios during 32 sessions. The collected data from the participants’ answers to the attitude questionnaire and interview as well as the data from assessing their performance throughout the course were analyzed both descriptively and inferentially. The analysis of the data revealed that the podcast-mediated blended L2 learning scenario appeared as the most successful scenario in L2 vocabulary learning. Consequently, it could be concluded that providing miscellaneous practicing opportunities for students would facilitate learning process and contribute to learning improvement.

Teacher questions are claimed to be constitutive of classroom interaction because of their crucial role both in the construction of knowledge and the organization of classroom proceedings (Dalton Puffer, 2007). Most of previous research on teachers’ questions mainly focused on identifying and discovering different question types believed to be helpful in creating the opportunities for learners’ interactions. Drawing on conversation analysis through adopting socio-cultural perspective, this study, however, aims to examine how EFL teachers manage understanding-check questions in their talk-in-interaction. For this purpose, six EFL teachers’ discursive classroom practices were observed, video-recorded, and transcribed line-by-line in its entirety. Through the microanalysis of the transcribed data, our findings suggest that EFL teachers vary in their management of understanding-check questions and the teachers’ understanding-check questions tend to serve different functions in the different micro-contexts identified. Three major sequential environments emerged to feature understanding-check questions in this study: Activity-boundary environment, post-instruction environment and within-activity environment. The findings of the study indicate that understanding-check questions at activity boundary environment are designed to accomplish dual functions, however those launched in post-instruction and within-activity environments maintain a singular focus on ensuring absolute understanding of the just-given explanation or instruction.

Veryfew attempts have been made in the past to develop instruments to measure pragmatic knowledge of second language (L2) learners. The absence of such instruments in the literature of English language teaching (ELT) underscores the need for the researchers to develop new tests that are specifically designed to assess this crucial but less explored aspect of language learners’ (LLs) knowledge. In line with this objective, the present study was conducted to develop and validate four tests of pragmatic knowledge that measured LLs’ knowledge of speech acts. The following steps were taken in this study to develop the written discourse completion tests (WDCTs) and the multiple-choice discourse completion tests (MCDCTs) that respectively measured the test takers’ ability to produce and comprehend request speech act. During the “prototype step” the researchers identified the content and the number of items for each designated test battery. At the “test construction step” the sociolinguistic variables of power (P), social distance (D), and absolute rank of imposition (R) were inserted into the content of the test items. Finally, at the “validation step” the reliability of the tests was examined. The finding of the study showed that the constructed test batteries were sufficiently reliable and valid for measuring pragmatic knowledge of L2 learners.
