Following controversies over teaching communication strategies, the present study, first, examined the impact of language proficiency and extraversion/introversion on the use of communication strategies (hereafter CSs) by administrating communication strategy questionnaire developed by the researchers on the basis of Dornyei and Scott's (1997) Inventory of Strategic Language Devices and the Persian restandardized form of EPQ to 182 students at elementary, pre-intermediate, and intermediate levels in a private English Language Institute. The One-way ANOVA and independent sample t-test analyses were performed to examine the effects of language proficiency and extraversion/introversion on the use of CSs. The analyses of the data indicated that language proficiency does not influence the use of CSs and CSs favored by introverts are similar to those favored by extraverts they only differ in the use of a few strategies. Second, the impact of teaching CSs of circumlocution, appeal for help, time-stalling devices, and message abandonment on Iranian EFL elementary students' oral performance was investigated. Four intact classes were selected (3 as the treatment groups with 27 students and 1 as the control class with 20 students). Data were collected through video/tape recording of pre and post tests of picture description, telling a story, and telling a joke and CSs were identified on the basis of Dornyei and Scott's (1997) taxonomy of CSs. The Chi-square analysis of the findings revealed that teaching circumlocution, appeal for help, and time-stalling devices are pedagogically effective.

This study investigated the main sources of Iranian students' demotivation in L2 learning and examined demotivation in relation to students' gender and level of education. To find the major demotivating factors, a questionnaire consisting of 32 items was developed and completed by 327 students. An exploratory factor analysis was conducted to explore the factorial structure of the questionnaire. Based on the results, five categories of demotivating factors were identified: Learning Contents, Materials, and Facilities, Attitude towards English Speaking Community, The Teacher, Experience of Failure, and Attitude towards Second Language Learning. To examine demotivating factors in relation to students' gender and educational level, two one-way analyses of variance were run. The results indicated significant differences between male and female students in terms of three demotivating factors. Significant differences were observed between students at different levels of education with regard to the three demotivating factors. Finally, a multivariate analysis of variance was performed to examine demotivating factors in relation to students' gender and educational level. Significant differences were found between male and female students across educational levels in terms of all demotivating factors except one.
