"Education is a double-edged sword. It can shape students' personality, and it can also kill students' personality. " The role of teachers is to create an atmosphere and conditions conducive to the development of students' personality. In teaching, we should give full consideration to students' existing life experience and personality differences, and pay attention to the development of students at different levels. Break the shackles of the traditional "holistic" teaching concept, pay equal attention to the whole and the individual, and adopt "hierarchical teaching" and "classified teaching". First, the implementation of classroom teaching stratification. Students' personality is an important factor affecting students' learning quality. In teaching, we should let students develop their strengths and avoid weaknesses, give guidance in different categories, design different questions, focus on the development of students at different levels, and "jump peaches and pick peaches", so that students with strong ability can develop their thinking, students with medium ability can develop their interests, and students with poor ability can master methods, so that students at different levels can be improved accordingly. The requirement of "guaranteeing the bottom without capping" in Chinese literacy teaching is to fully consider the differences of students. Second, the implementation of post stratification. Assigning homework is a means to check the quality of teaching and students' knowledge, and it can't be the same. After mastering the learning effect of students at all levels in this course, we can carry out hierarchical design, such as: required questions, selected topics and highlighted questions, so that different students can complete exercises with different quantities and difficulties. Through the design of layered homework, all students can implement new knowledge to varying degrees and are full of confidence and interest in learning.
