It appears that, discovering the relationship between Multiple Intelligences, Learning Styles and Strategies is a relatively new issue which has recently become important and has drawn attention to English teachers. Moreover, there has been little attempt applied to the evaluation of the effectiveness of strategy-based instruction on improving the reading comprehension ability of EFL learners. In a bid to address this issue, this book was conducted to investigate the relationship between multiple intelligences, learning styles and strategies and EFL learners' language proficiency. Moreover, it was aimed to consider whether strategy- based instruction affects the multiple intelligences, learning styles and strategies of EFL learners. Last but not Least, the current book attempts to investigate whether applying strategy-based instruction improves reading comprehension ability of EFL learners at upper-intermediate and advanced levels.
