Teach important concepts and principles first.
Step by step according to the difficulty and level! This method has been used in mathematics from a small scale to a large scale. Let me take mathematics as an example: the first stage: 1. Teach a number to add 2. Teach a number to subtract 3. Teach a number to multiply by 4. Teach a number to divide by 2: 5. Teach two-digit addition 6. Teach two-digit subtraction 7. Teach two-digit multiplication 8. Teach the division of two digits 3: 5. Method 6. Teach the subtraction of three numbers and four numbers. Multiplication teaching of three digits and four digits. .................................................................................. spiral teaching method can not only strengthen cognition through repeated learning.
And really step by step! For example, students failed to understand the concept of addition in the first stage.
Only know how to calculate.
There is still a chance to understand later, and students don't need to constantly learn the addition from one digit to triangle.
Addition of calculus, etc 。
Spiral teaching method is not only simple from shallow to deep! Take my computer programming teaching as an example: grade one: teaching students program concepts and flow charts, never teaching any computer language; Second grade: review the first grade course, then teach MindStorm (building robots with Lego) and learn to write simple programs to control robots; Grade three: review the second-grade courses, then teach Pascal or VB, learn input, output and calculation, and realize the four middle schools and five middle schools in the flow chart (if ... then write): deep process control, file processing and so on. And even do projects. As you can see, the same project (computer programming) is from shallow to deep, but when you study in different grades, you will never use a certain grade to study the whole project. In this way, students have enough time and ability to understand the meaning of this topic.

Spiral teaching: the same theme will appear repeatedly in different eyes; In retrospect, there will be something to learn next time; In this way, each class will cover review, study and preview. The so-called spiral learning is not always to let children stack up and recite new words, but to take detours. When you go forward, the old words account for the majority, and then add some new ones, or put the learned words into new situations and contexts to learn. A truly excellent teacher is a teacher who knows how to link to the old knowledge base known by students, how to introduce new words through sentence patterns that students have already learned, or how to review old words with new sentence patterns when teaching new syntax or vocabulary. In this way, students can constantly learn new things and review old things, which becomes spiral learning. Instead of learning too much "possible but unrealistic". Spiral teaching is also a good solution to the current double-peak phenomenon. Children who have learned, slow down, don't wait for others, but stabilize your learning foundation, don't build your foundation on sand. What is spiral teaching method?
