摘要:In the past two decades, self-regulation has been the center of heated debate in educational psychology. The present study attempted to investigate the relationship between Iranian EFL learners' self-regulated learning components and vocabulary knowledge and reading comprehension .To fulfill this objective, a 60-item vocabulary and reading comprehension TOEFL test was administered to a sample of 250 male and female college students majoring in English Teaching, English Language Translation, and English Literature. The Persian version of “Self- regulation Trait Questionnaire” was administered to the same participants. Pearson correlation procedure was used to analyze data. Results indicated that the correlation between self-regulated learning components: planning, self -checking, effort and self-efficacy gave mixed results. That is to say, two of the correlation coefficients, self –checking and effort were significant while the other two, planning and self-efficacy, were non-significant.
