Argument maps as schematic representations of arguments and their logical and evidential relationships are effective diagrams for instruction in education as well as in L2 development. However, their use for teaching L2 writing in EFL contexts has not been adequately studied. Therefore, this study investigated the effect of argument mapping instruction on Iranian EFL learners’ writing achievement and writing components, including grammar, coherence, cohesion, and task accomplishment in expository and descriptive essays. The participants were 60 intermediate EFL learners at Fadak language institute in Tehran. The selected participants were randomly divided into two groups: an experimental and a control group, each including 30 participants. Materials, coursebooks, and the teacher were the same for the study groups. However, the participants in the experimental group received specific instruction about the use of argument maps before and during their writing. After 10 sessions of treatment, the learners in the two groups were asked to write a descriptive and an expository paragraph. The paragraphs were rated by two raters and the final score was the average of the scores given by the two raters. The results of the data analysis revealed that argument mapping strategies had significant improvement impact on expository and descriptive writing tasks and could improve participants’ writing in terms of grammar, coherence, cohesion, and task achievement. However, argument mapping was not beneficial in improving the vocabulary of study participants’ writing. Findings of the study suggest that EFL language instructors and learners can use argument maps for teaching descriptive and expository writing.

Despite the importance of author engagement in the literature review of academic articles, many writers fail to publish their academic articles due to being incompetent in using conventional engagement resources. In view of this problem, the present study aimed to study linguistic representation of engagement as a dimension of evaluation in academic articles published in international and Iranian local journals. To do so, the literature review section of eighty psychology and applied linguistics articles as representatives of humanities and mechanical engineering and medicine articles as representatives of hard science articles published between 2008 and 2017 in the international and Iranian local journals formed the corpus of the study and were analyzed on the basis of the engagement resources proposed by Martin and White’s (2005) Appraisal Theory The findings indicated that monoglossic resources were used more frequently in articles published in local journals than those published in international ones. Regarding heteroglossic resources, intra-vocalizing resources (countering, denial, pronouncement, and entertainment) were found more frequently in articles published in international journals. However, extra-vocalizing resources (endorsement and attribution resources) used in local journals outnumbered those used in international ones. The findings can provide insights for teaching academic writing in EFL contexts.

Scholarly mails apparently display stable conventional principles as an emerging genre. Thus, contributors should structure their electronic mails appropriately when writing for purposes of discussing professional topics. However, this requirement plunges many a scholar in dilemma as to how to go about this vital undertaking without written structural norms in electronic mail communication. This raises the question: what is the generic structure of the scholarly electronic mail? The aim of this paper therefore is to uncover the organizational structure of the scholarly electronic mail as an emerging genre of computer mediated discourse. A qualitative approach is adopted in the description of the generic structure. Through purposive and stratified sampling, twenty scholarly electronic mails were selected and closely studied based on the basic electronic schema model by Herring (1996) with a view to extracting the features of the genre. Findings revealed that the scholarly electronic mail has a generic structure which is signalled by typical linguistic elements. The paper recommends a genre-based approach to guiding upcoming scholars on how to construct a scholarly electronic mail that fulfils its communicative purposes.
