This study examines the impact of teaching learning strategies on learners' beliefs about language learning and reading comprehension ability. Participants were 78 university freshmen studying English language teaching, translation, and literature. They were divided into two groups. The experimental group received a number of learning strategies adopted and adapted by the researchers, including concept-mapping, vocabulary notebook, passage restatement, dictionary use, summary writing, and guessing. The treatment was carried out 4 hr a week for 15 consecutive weeks. The Language Learners' Beliefs Scale, developed and validated by Birjandi and Mohammadi, and the reading comprehension section of Cambridge Preliminary English Test (PET) were administered before and after the treatment to identify the students' shifts in beliefs about language learning and to measure reading comprehension ability, respectively. The results of independent t test indicated that the instruction of learning strategies changed the university students' beliefs about language learning. Furthermore, learning strategy instruction could boost their reading comprehension ability.
