The book "Motivation and Language Learning Strategies" by Mohammad Salehi offers a comprehensive examination of the relationship between motivation and the strategies that students use in language learning. The study analyzes how various factors, including gender and language proficiency, influence the choice and use of learning strategies. By employing validated instruments, including questionnaires on motivation and learning strategies as well as a TOEFL test, the research provides valuable insights into the dynamics between intrinsic and extrinsic motivation. The results show that intrinsic motivation has a significant impact on the choice of learning strategies, while extrinsic motivation does not exhibit a meaningful correlation. Additionally, it is noted that there are no gender-specific differences in the choice and use of strategies, and that language proficiency does not affect the strategies employed. This book is a valuable resource for students, educators, and researchers in the fields of linguistics and educational psychology.
