The language register used in academic communities has the special features of density, complexity, and abstractness which are associated with nominalization with which new members of the communities might not be familiar. To explore the possible distance between novice and established members regarding their awareness of this grammatical feature, the present study investigated the employment of nominalization in the writings of Iranian graduate students (both MA and PhD students) and experienced figures in applied linguistics. Forty five research articles in the discipline by the three groups of writers served as the corpus of the study. A rigorous analysis began by identifying and outlining nominalization instances manually through and per all rhetorical sections of the articles. The occurrences of the two types of nominal expressions was counted and normalized. So as to detect the possible significant differences between the samples, chi-square tests were run. The results revealed that the experienced writers used significantly more nominalization in their writings. However, although the total nominal expressions used in MA texts were more than those used in PhD texts, the difference turned out not to be significant. There were also similarities and variations in the ranking patterns of the two types of nominalization in four rhetorical sections of the three groups of the articles. It can be concluded that the differences might reflect the distance between the novice and the established authors regarding their awareness of the importance of nominalization in academic writing. The implications of the study for EAP courses were also discussed.

Hedging academic claims has been recognized as one of integral pragmatic features of academic writing in which most EFL academic writers seem to face substantial problems. Explicit instruction has been proposed by some scholars as an effective approach to make EFL writers aware of the importance, different forms, and pragmatic functions of hedging devices some of which are polysemous and polypragmatics (e.g., Hyland 1996a). The present study with the aim of shedding more light on the effectiveness of explicit instruction in improving the pragmatic knowledge of Iranian EFL learners in terms of hedging devices, investigates the acquisition and use of English modal auxiliaries as hedging strategies via applying a direct teaching strategy in the classroom. To this end a sample of 37 undergraduate students majoring in different fields of study were recruited and assigned into a control and experimental group. Explicit instruction of the modal auxiliaries as hedging resources was applied for the treatment group while the control group received only the regular academic writing instruction. A pretest and a posttest were administered to the two groups. The descriptive analysis of the scores as well as the results of the t-tests revealed a significant progress in the participants’ linguistic and pragmatic knowledge of modal auxiliaries as hedges in the treatment group. The results also indicated that the experimental group outperformed the control group in acquiring and using modal verbs to hedge their claims. The findings of the study provide insightful implications for the administrators of educational programs.
