Improving second language reading comprehension through reading strategies: A meta-analysis of second language reading strategy interventions

Effective readers consciously or unconsciously use reading strategies to help them process information on what they read. All readers can benefit from reading strategy instruction but, empirical research on which strategies are effective is lacking. Less is known about reading strategy effectiveness in a second language (L2). This meta-analysis of 46 L2 reading strategy studies analysed ten reading strategies, also in combination with a range of pedagogical approaches, and found an overall mean effect size of 0.91, underscoring the benefits of multi strategy teaching. Effect sizes were calculated for each strategy, as well as the combination of strategy with approach, instructor type, intervention duration and type of test used. Some strategies were more effective than others. Also, differences in effect sizes are dependent on the approach used. Some pedagogical approaches are effective for some strategies but not with all. We recommend further research in L2 reading strategy interventions and instruction.
