The metacognitive strategies used in reading were studied for students from grade 2 through grade 12 (no data were collected for grade 4). The Strategic Teaching and Reading Project (STRP) is a research-based instructional improvement and staff development project to improve reading comprehension. Ten K-12 public schools, and 1,570 students participated in this study. All schools and teachers participated in a 2-year STRP plan. Teachers were exposed to and trained on five global reading strategies of STRP, including metacognition, for 3 consecutive days and were given training in using the approach in the classroom. The researchers created a framework of 35 metacognitive behaviors based on a literature review. Findings suggest that students used 19 of the 35 metacognitive behaviors. The fact that metacognitive strategies proved effective suggests that these strategies should be integrated into instruction for students at various ability levels, ages, and grade levels.
