The Evaluation of Iranian ELT Textbook Based on the Vocabulary and Verb-Form Frequency Lists

The current study was set to investigate the extent to which the presentation of lexical items in Iranian ELT textbooks complies with the related frequency list available in the related literature. To this end, the researcher utilized West’s (۱۹۵۳) general service list, Coxhead’s (۲۰۰۰) academic word list and George’s (۱۹۶۳) verb form frequency list. In a descriptive-analytic study, the researcher traced and compared the distribution of the lexical and structural items in Iranian ELT textbooks with the stated frequency lists. The findings of the study revealed that the presentation and distribution of lexical items in Iranian ELT textbooks comply with the West’s (۱۹۵۳) general service list. However, possibly due to the nature of the corpus under the study, the lexical items in the Iranian ELT textbooks barely match the lexical items in Coxhead’s (۲۰۰۰) academic word list. Furthermore, the result showed that the distribution and the order of the structural patterns in the investigated corpus are not consistent with George’s (۱۹۶۳) verb form.
