The present study aimed to review the instruction of the L2 speech acts in English pragmatics in the Iranian context during the last two decades from 2000 to 2020. To this end, upon the completion of the study search, the retrieved articles were selected and analyzed based on the research domain.  The results of our synthesis from 54 studies carried out on the instruction of the speech act not only reveal that pragmatics is amenable to instruction but also unfold that the most frequently instructed speech act is the speech act of request which has been conducted in 29 studies, while the least instructed speech act is  invitation, used in only one study. Moreover, analyzing the data collection methods documented that Multiple-choice Discourse Completion Test (MDCT) is the most predominant method utilized in 36 papers during the last decades in English pragmatic instruction. With respect to the treatment types, it is illuminated that the most recurrent treatment type is explicit, implicit vs. control, followed by explicit vs. implicit, although other treatment types have been embarked on. As a final point, it is worth noting that 53 of the conducted studies utilized the quantitative method in their data analyses, whereas only one study implemented the qualitative method. The paper concludes with some avenues for further research.

Designing appropriate materials and activities to enhance vocabulary learning is one of the primary goals of language courses. Among the claims about efficient pedagogical tasks is the Involvement Load Hypothesis (Laufer & Hulstijn, 2001) according to which vocabulary development is contingent on the amount of cognitive process a task involves. Building on the previous research on this hypothesis, this study seeks to explore the extent to which three post-listening tasks of different involvement loads along with single-versus dual-mode glosses affect receptive and productive vocabulary learning of advanced English as a foreign language (EFL) learners. The participants (n = 204) listened to an expository text while twenty lexical items were presented through text-only or text-plus-picture glosses. Subsequently, they were assigned to one of the task type groups (sentence writing, gap-fill, and paragraph writing). Paribakht and Wesche’s (1997) Vocabulary Knowledge Scale was employed as the pre and post-tests. The results pointed to the efficacy of dual-mode over single-mode glosses concerning both receptive and productive vocabulary learning. The sentence writing task produced the highest scores in the vocabulary tests, whereas the gap-fill and paragraph writing tasks did not significantly differ. Hence, the results only partially confirmed the Involvement Load Hypothesis. The current study corroborates other studies verifying the modality effect on vocabulary learning and suggests that task type is a significant factor in EFL vocabulary learning.

Despite the abundance of research investigating general and academic vocabularies and developing dozens of word lists, few studies have compared academic vocabulary with general service word lists such as conversation vocabulary. Many EAP researchers assume that university students need to know all the words in West’s (1953) General Service List (GSL) as a prerequisite to academic words (e.g., Coxhead’s, 2000) and teachers at language institutes recommend conversation students to learn words in Coxhead’s Academic Word List (AWL) as a follow-up to the GSL. The present study compared the academic and conversation vocabularies by exploring frequency and coverage of words in academic and conversation corpora. The GSL and AWL words were investigated in a conversation corpus and an academic corpus, each containing around 12 million running words. The analysis revealed that 1200 GSL word families were highly frequent in both corpora and 645 GSL word families were highly frequent in the conversation corpus but of low frequency in the academic texts. Also, a new academic word list of 700 word families was developed, which proved to be much more rigorous than Coxhead’s AWL. Further analysis indicated that the abovementioned 645 GSL words had a very low coverage of academic texts (0.7%), while they covered 4.05% of the conversation corpus. The new academic word list covered only 1.6% of the conversation corpus, whereas it had a high coverage of the academic texts (9.1%), much higher than that of the AWL (7.5%). The analysis of some other academic corpora revealed identical results.

In the realm of second language acquisition (SLA), task-based language teaching (TBLT) and input enhancement (IE) have been the focus of a great number of studies. However, the idea of investigating the effects of focus on form instruction through input-enhanced tasks along with pre-task planning time as one of the features of task-based language teaching has been rarely explored in the field of SLA. Therefore, the current research set out to examine the impacts of focus on form instruction via textually-enhanced reading tasks along with strategic pre-task planning on L2 learners’ grammatical development in terms of learning English passive voice. For the purpose of the study, 60 intermediate learners of English were selected and divided into two groups of thirty namely as enhanced and unenhanced. Then, each group was divided into two sub-groups of fifteen as +planning and -planning. The participants were provided with a pretest prior to the treatment, then, they were instructed via the materials chosen for the purpose of the study for ten sessions and at the end they were provided with the posttest of the study. Their performance on the pretest and posttest were analyzed to find out the possible effects of the instruction provided throughout the treatment phase. The results revealed that learners who were exposed to enhanced reading tasks along with strategic pre-task planning time outperformed the other learners. The findings of the present study can be of use for language teachers, syllabus designers, and task designers.
