Metacognitive skills help students develop skills such as problem-solving, critical thinking, leadership, and responsibility. This chapter aims to examine the concepts of cognition, metacognition, metacognitive strategy, and metacognitive skill within a theoretical framework and to reveal the place of these concepts in education. In the research literature review method was used. In the light of the results obtained based on the research findings, it was determined that metacognitive strategies help students improve their cognitive skills during the learning process and are related to academic success. This research reveals the need to emphasize the importance and place of metacognitive skills in education, to teach students strategies, and to guide them when and where to use them. Additionally, students need to gain appropriate experiences and practice to develop their metacognitive skills. Metacognitive development begins at an early age and continues throughout the teaching process; therefore, it is very essential to carry out activities that support metacognition, especially at preschool and primary school levels. The general conclusion is that developing metacognitive skills increases students’ cognitive competencies and makes them responsible for their learning, which in turn enables students to become more independent learners and increases their overall academic success.
