This action research project empirically evaluated the efficacy of reading strategy instruction to help advance adult English as an additional language (EAL) students' development of academic reading skills and strategy use. The study involved 16 adult participants attending English for Academic Purposes (EAP) programs in British Columbia. These participants received reading strategy instruction over nine sessions during a 6-week period. To capture participants' reading strategy use, Mokhtari and Sheorey's Survey of Reading Strategies instrument was used in the pre- and post-intervention stages. Similarly, to measure participants' reading comprehension abilities, an identical, standardized reading comprehension test was administered in the pre- and post- intervention stages. Participants' weekly post-task verbal reflections and post-intervention interviews provided qualitative data for the study. Findings showed that reported reading strategy use obtained from the instrument and reading performance increased significantly after the intervention. The results from the analysis of participants' reflections and interviews revealed a positive association between participants' strategy use and reading performance. Conducted as a part of professional development, this study aims to resolve EAP professionals' practical concerns about the use of reading strategies in academic reading as well as provide action researchers with suggestions for future implementation.
