Decoding Success: Investigating the Impact of Trait and State Strategies on Reading Test Performance among Thai High School Learners

The field of second language (L2) acquisition has increasingly emphasized learner strategies, cognitive and metacognitive methods, as crucial factors in individual differences and reading comprehension. Grounded in Bachman and Palmer's communicative language ability (CLA) model, this study investigates how strategic competence in cognitive and metacognitive strategies impacts reading comprehension among Thai high school students. By employing quantitative methods, including structural equation modeling (SEM), the study explores how trait strategies (perceived strategic knowledge) and state strategies (actual strategy use) influence reading test performance. The research involved 685 students from a public high school who completed Likert scale questionnaires about their strategy use before and after comprehension tests. Results reveal that state strategies are employed more frequently than trait strategies and show a significant positive correlation with reading performance. While cognitive strategies like comprehension and memory are critical for understanding text content, metacognitive strategies like planning and monitoring improve learners' ability to regulate their strategic application. However, evaluation strategies were found to be less frequently used. The study's findings advocate for balanced training in both cognitive and metacognitive strategies to bridge the gap between strategic knowledge and effective application, thereby empowering learners to become more autonomous and proficient readers. Further research should investigate strategic competence in different cultural contexts, employ longitudinal studies, and expand the research to other language skills to gain a comprehensive understanding of L2 learners' strategies.
