Three global elementary ELT textbooks, namely Interchange, Top Notch, and American English File along with the local elementary textbooks of Iran Language Institute (ILI) Series, were examined for their pragmatic content. To analyze the pragmatic content of these textbooks, the researchers used three different frameworks.

Writing skill is an essential requirement to lifelong learner success, yet the way teachers provide feedback for their students on writing is quite challenging. One of the new trends in writing skill instruction is Self Assessment.

This paper describes the findings of an investigation on using self assessment in EFL writing classroom. For the purpose of conducting this research, 48 Iranian upper intermediate students, all male and with age range of 20 to 23, were chosen to participate in this investigation. These participants were divided into two equal groups: an experimental group (N=24) who worked on their writings through self assessment and a control group (N=24) who worked on their writings based on the traditional ways. It was found that participants in the experimental group significantly improved their writing proficiency means score, whereas improvement in the control group was not significant.
