The present study investigated the impact of language learning strategy instruction on the enhancement of less successful Iranian English as a Foreign Language (EFL) learners’ L2 achievement. To this end, 40 less successful EFL students took part in the study, 20 of whom were trained based on CALLA (Cognitive Academic Language Learning Approach) and the rest formed the control group. A complete TOEFL PBT test was administered to the 40 participants of the study to homogenize them in terms of language proficiency.The results of two independent samples t-tests and two separate paired samples t-tests indicated that explicit strategy instruction had a significant positive impact on L2 achievement of less successful Iranian EFL learners as the participants in the experimental group significantly outperformed their counterparts in the control group. The results of the current study might contribute to the educational policymakers,  materials writers, syllabus designers, curriculum developers, and foreign language teachers to incorporate learning strategies in their policies, curricula, syllabi, materials, and instructional tasks if they intend to boost EFL learners’ L2 achievement.

Though personality factors and language learning strategies have been extensively examined over the last three decades, we have witnessed a dearth of studies zooming in on these issues from a cultural perspective within the Iranian context. Additionally, few studies have investigated whether personality factors can predict the choice of language learning strategies in an Iranian EFL context. In response to these shortcomings, a group of Iranian EFL learners were administered Big Five Factors Inventory (Goldberg 1993), Strategy Inventory for Language Learning (Oxford 1990) and Metacognitive Awareness of Reading Strategies Inventory (Mokhtari & Reichard 2002). It was found that the Iranian EFL learners could highly or moderately used the language learning strategies. It was also found that personality factors could predict the use of some language learning strategies in the cultural context of Iran. It was concluded that cultural norms could modulate some aspects of personality and language learning strategies and consequently some aspects of personality could predict the choice of particular language learning strategies. An awareness of learners’ personality factors and the way they shape the language learning strategies can contribute to successful language learning and optimally help teachers devise appropriate teaching techniques.
