In the tutorial system classroom teaching, we should achieve "four essences and four essentials", that is, selection, refinement, refinement and evaluation, receipt of development, evaluation of receipt, evaluation of batch and supplement of evaluation. Teachers must carefully select materials, cognitive strategies and feedback information according to the teaching materials. Optimize the teaching plan, optimize the teaching methods, and work hard to grasp the "key points", highlight the "difficulties" and solve the "doubts". Teachers should inspire and awaken students' subjective consciousness, create a stage for students to perform and make the classroom full of charm.
