A correlational survey research design was utilized to investigate self-regulated Learning (SRL) and teacher-student interaction factors that had been realized to have contributive roles in EFL learners' academic success. A sample of 218 EFL learners (male = 102 and female = 116) was drawn with the aid of a prior sample size calculator for the structural equation models from 645 students. They were within the age range of 18-45 and were enrolled at Islamic Azad University, Tabriz Branch. The structural equation model (SEM) hypothesis testing procedure revealed that the teacher-student interaction directly and significantly influenced learners' academic accomplishments. Likewise, the obtained results indicate that the impact of the teacher-student interaction on EFL learners' academic achievement is mediated by the effects of SRL. Correspondingly, the obtained results indicate that the theorized model fits the data. The causal contribution of psychological factors, consisting of the teacher-student interaction and SRL, to EFL learners’ academic achievement was validated. The findings of this exploratory research have certain implications for classroom practice which are elaborated in detail in this paper.

This study explored the relationship between EFL learners’ vocabulary size, lexical coverage of the text and reading comprehension texts (narrative & argumentative genres). To this end, 120 male and female out of 180 students studying at Talesh Azad University were selected based on their performance on the Nelson Proficiency Test. A Nelson reading proficiency test was also administered in order to check the homogeneity of the learners in their reading proficiency. After that, the researcher administered reading comprehension tests with narrative and argumentative genres in order to find the lexical coverage and vocabulary size for such reading tests. Learners' Vocabulary size was measured by the Levels Test, while their lexical coverage was measured by the newest version of Vocabulary Profile. In order to probe any significant relationship between the variables of the study, Pearson Correlationwas run. Results of the study showed that there was a strong relationship among vocabulary size, text coverage, and reading comprehension test at different genres.
