Metacognition is often described as the awareness and regulation of learning. It uses strategies which include monitoring one's own thinking, engaging in active planning and self-evaluating one's study habits. Bloom's taxonomy can be used as a metacognitive tool to guide students' study strategies and thus improve their academic performance by promoting higher order learning. The following study was conducted over multiple years and in several university biology classrooms to determine whether a brief instructional activity on metacognition and Bloom's taxonomy would cause students to reflect upon and perhaps revise their study strategies. The results of our study suggest that with a minimal effort, and using simple, universal metacognition interventions, instructors can elicit students to reflect upon their own thinking processes, revise their study strategies to foster deeper learning, and achieve higher learning outcomes. An additional, significant outcome of the metacognition interventions presented here could be the transformation of individual student engagement with course content into a more holistic, collaborative learning community.
