Simple is the most powerful——overall teaching design of integral expression operation

It wastes time and energy to teach traditional integral expression operation. This is because people analyze the teaching material excessively and mechanically. It has separated the relations between various knowledge. Thus the main knowledge is not prominent. As a result, it has caused the students to lose the instinct thinking. The key point to solve this problem is to simplify the teaching content. All algebraic expressions equal a number. All changes are the simplification of the algebraic expression. The essence of the traditional integral expression operation is consistent with the operation of arithmetic. The students will be given the autonomy to explore it freely.
