The present experiment was composed of both qualitative and quantitative methods and aimed at investigating Reading Metacognitive Strategy Awareness (RMSA) and use by the aid of three inventory techniques including a questionnaire, a think-aloud protocol, and a Computerized RMSA System. The computerized system was specifically designed and validated to satisfy the needs of this study in measuring and practicing Reading Metacognitive Strategies. It also tried to explore any possible effects of Computerized RMSA System on reading comprehension of the participants. To this end, a sample of 25 university students majoring in English Translation and English Literature from a University in Iran were selected based on purposive and clustered sampling. The research data were selected using a number of instruments including the reading section of Test of English as a Foreign Language as pre/posttest, a researcher-made Reading Metacognitive Strategies questionnaire, think-aloud protocol and a Computerized RMSA System. The research findings show that the questionnaire, think-aloud and Computerized RMSA System results vary significantly. Moreover, Computerized RMSA System has a positive effect on reading comprehension of learners of English as a Foreign Language. Pedagogical implications of the findings are discussed.
