The concept of teacher change is critical in second language teaching and English as a Foreign Language (EFL) context due largely to the fact that, almost, whatever we do in teacher education looks for initiating change of one sort or another. A substantial body of research has been dedicated to investigate teacher change (TC) from various perspectives. However, having studied the related literature, we found no robust, valid and reliable measure for TC in EFL context. Accordingly, effort was made to develop and validate a reliable and valid measure that could assess TC in an EFL context. The review of the prior research resulted in the collection of 186 items affecting TC out of which a temporary data driven model of teacher change was developed. 324 Ph.D. and M.A. graduated EFL teachers took part in exploratory and confirmatory factor analyses of the initial measure. Finally, a 66-item scale consisting of three components and thirteen sub-components was developed.The results showed both factorial validity andinternal consistency reliability for the measure.The TCSsubscales also had strong validity evidence based on the associationsfound. This study has various applications for language teachers and practitioners in the field.

Task difficulty across different macro-genres continues to remain among less attended areas in second language development studies. This study examined the correlation between task difficulty across the descriptive, narrative, argumentative, and expository macro-genres. The three components of task difficulty (i.e., code complexity, cognitive complexity, and communicative stress) were also compared in the four macro-genres. The design included the administration of short reading texts with comparable length and readability indices based on the four macro-genres followed by task difficulty questionnaire. The macro-genre-based reading textsalong with the task difficulty questionnaire were administered to 50 EFL students in the University ofLorestan, Iran. Task difficulty questionnaire explored the learners’ perceptions of task difficulty in the code complexity, cognitive complexity, and communicative stress domains. The results revealed that there were no significant differences among the task difficulty components in the four macro-genre-based text types. The findings also showed that there was no significant correlation between task difficulty of each macro-genre with those of the other genres except thoseofthe narrative and expository genres.The findings hold implications for the use of macro-genres with different task difficulty indices in task-oriented programs, teacher training, and testing.
