First, prepare lessons at different levels.
As we all know, preparing lessons is the premise of good class and the key to improve teaching quality. The concept of hierarchical teaching requires teachers to do this well. Therefore, when preparing lessons, teachers should carefully study the teaching materials, determine specific and feasible teaching objectives, and distinguish which belong to the same goal and which do not. While grasping the teaching objectives, different requirements at different levels are determined according to the knowledge level of students at different levels. Under the condition of grasping the essence of the problem and understanding the process of knowledge occurrence, development and formation, set up a reasonable cognitive ladder: set the image memory content as the first ladder to ensure that students in Group A can "eat"; Abstract understanding of the content is the second step, so that students in group B can "eat well"; The content of knowledge expansion is the third step to satisfy the "satiety" of group C students.

Second, the class combines layered teaching, classified guidance and layered exercises.
Hierarchical classroom teaching is mainly based on the general teaching law of from shallow to deep and from easy to difficult, and the arrangement of knowledge and time has been greatly improved. As far as the new teaching is concerned, it is divided into three stages, which are independent and coherent, so that students at all levels can understand their role in this learning stage and play a directional role in the development of thinking. In terms of time arrangement, the teaching time of the first and second stages should be fully guaranteed, which is generally 25 to 30 minutes. This can ensure that students in Group B and Group C can understand and understand thoroughly. The third stage only takes about 5 minutes, so that the students in Group A can have a aftertaste, that is, the lower bound (so that every student can master the most basic content) and the upper infinity (directional inspiration and extracurricular expansion).
Third, hierarchical evaluation
Sense of success is an important factor for people to successfully complete a job. The same is true of learning. On the basis of the above-mentioned graded teaching, students successfully completed this cascade of learning tasks, and often worked overtime to answer questions and complete homework. At this time, teachers should further cultivate students' confidence, reform examination methods, and let students achieve satisfactory results.
