Meta-teaching is the knowledge and reflection on teaching based on meta-ideas. It is the teaching about teaching, a teaching process with practice consciously guided by thinking, inspiring teachers to teach more effectively. Meta-teaching is related to the knowledge, inspection and amendment of teaching activities in terms of their design, practice, process, and results. It primarily consists of such dimensions as the clarification, representation of and reflection on teaching activities, and functions to keep the internal impetus for teaching, promotes effective learning, effective teaching, sustainable development of teachers for their profession, as well as the development and perfection of teaching pedagogies. Absence of meta-teaching in current teaching practice highlights the necessity for teachers to understand and master meta-teaching strategies in the classroom so as to help students better understanding their learning process, facilitating them with meta-learning and cognition strategies, as well as encouraging their meta-thinking.
