**Abstract**

Teachers' role in chemistry metacognition describes what metacognition and chemistry metacognition are, their importance in chemistry education and how they can be taught or improved in science or chemistry learners that might be finding the subject difficult or demanding. This chapter educates science and chemistry teachers with the requisite metacognition and chemistry metacognition skills, knowledge and attitudes using chemistry relevant prior knowledge. The science and chemistry teachers in this chapter are also educated through a selected difficult chemistry topic on how to utilize the acquired metacognition and chemistry metacognition skills, knowledge and attitudes in the classroom. The metacognition and chemistry metacognition skills, knowledge and attitudes are utilized through modeling and scaffolding by the science and chemistry teachers for the learners to observe and learn metacognition and chemistry metacognition in practice. Replace the entirety of this text with your abstract.
