Most of the studies in Interlanguage Pragmatics have focused on the performance and acquisition of speech acts by nonnative speakers, considering politeness only as a subsidiary issue. The present study pertains to linguistic politeness and attempts to investigate the effects of different teaching methods on the acquisition of English politeness strategies (PSs). Eight groups of freshman and junior English majors were randomly assigned to three experimental groups (enhanced input, explicit teaching, and role play) and one control group (mere exposure). The participants took a TOEFL test, a pretest, and finally a posttest after a seven-week treatment of a list of PSs. The results indicated that instruction has a significant positive influence on the acquisition of PSs and explicit teaching is significantly the most effective method. Role play and input enhancement were the second and third most effective. Moreover, it was shown that although the level of language proficiency significantly influenced the knowledge of PSs (the ability to recognize appropriate PSs for each social context), it did not affect the acquisition of PSs. The findings imply that the instruction of PSs can be started at intermediate level and explicit teaching alongside role play activities will greatly benefit language learners.

The current study reports the steps taken in the first phase of a larger project aiming at assessing the pragmatic competence of Iranian EFL learners with a focus on L2 (im)politeness features. To this end, a Multiple-choice Discourse Completion Test (MDCT) was developed, based on the scenarios present in two recently published webcomics. First, the types and the frequencies of the L2 (im)politeness strategies found in the webcomics were determined through discourse analysis.  Next, similar situations to those present in the webcomics were developed based on a table of specifications developed by the researchers. The developed (im)politeness questionnaire was first piloted by a number of native English speakers and improved according to their comments and suggestions. Finally, the finalized version of the questionnaire, i.e., the developed DCT, was administered to a few Iranian EFL learners for the final piloting. The steps taken and the findings of each one is reported and discussed.
