The current study attempts to explore the characteristics of author-assigned keywords in research articles as important constituents of targeted search in academic communities. To this end, the keywords of 200 research papers in the field of applied linguistics, in terms of domain, degree of specificity, and relation to the titles, were analyzed. To supplement the findings, the keyword choice strategy of a number of researchers with publishing experience in the field was also investigated. The analysis revealed a considerable rate of title-keywords match, especially with respect to field-specific keywords. This finding points to the importance of users’ field-specific background knowledge in locating relevant information on the web. The examination of authors’ viewpoints and strategies, on the other hand, helped to bring to light the complex and non-clichéd nature of keyword selection. The significance of authors’ diverging and converging attitudes and their implications for enhancing the success rate of keyword search are discussed.

Second or foreign language (L2) learners’ development of interlanguage pragmatic (ILP) competence to understand and properly interpret utterances under certain social and cultural circumstances plays a pivotal role in the achievement of communicative competence. The current study was designed to explore the effects of synchronous computer-mediated communication (SCMC) and asynchronous computer-mediated communication (ACMC) course modules delivered through social media networks (SMN) on the development of the Iranian L2 learners’ comprehension of implicatures. The participants of the study were 90 English-as-a-foreign-language (EFL) undergraduate students attending three intact classes. The classes were randomly assigned to one control and two experimental (SCMC and ACMC) groups. An open-ended implicature comprehension test was used to assess students’ ILP development in this pretest-posttest comparison-group study. The control group received the traditional teacher-fronted instruction, and the S/ACMC groups received instruction via synchronous and asynchronous modules of SMNs for 4 months, respectively. Students’ attitudes towards the CMC-based courses were also sought. Split-plot ANOVA results indicated that both experimental groups developed significant ILP ability to comprehend and interpret L2 implicatures after the instruction; however, by comparison, the ACMC group improved more considerably. It is concluded that, first, comprehending L2 implicatures is not impervious to computer-mediated instruction and, second, different CMC affordances may result in differential ILP developmental effects in teaching L2 pragmatics. The findings can help L2 teachers decide how to use CMC affordances and SMN modules to raise L2 learners’ pragmatic awareness

This study sought to evaluate the usefulness and desirability of the English textbooks for Iranian second grade students in senior high school, Vision 2. To this end, the extent to which the textbooks materials satisfy the prescribed curriculum was explored based on Littlejohn’s (2011) evaluative framework. Employing stratified random sampling, a total of 12 private and public senior high schools (six girl students and six boy students) were selected randomly among all the schools located in the six education districts in Isfahan. To select the teacher participants, a convenience sampling method was employed and those who agreed to be surveyed took part in the study. The 20 teachers who participated in this study have been teaching Vision 2 since the beginning of 2017 fall. The process of the content analysis deals with a deeply analytical content evaluation based on a framework containing different parts (objective description analysis, subjective analysis, subjective inference) done by a teacher committee. The results revealed that there is a need to adapt the materials to the target situation of use. Such adaptation needs to cover both design- and publication-oriented aspects of the materials. As a practical implication, the findings may urge the developers of the textbooks to launch a modification project relying upon the results of the systematic phase, therefore, it may enrich English teaching and learning material in Iranian high schools.
