Step9 Teaching Reflection
In this lesson, I took administrative-level teachings A,B, C according to the students’ different foundations. I asked the students of poor foundation to do easy exercises and the students of good foundation to difficult exercises and the others to do middle difficult exercises. That’s the case, they could do well and felt successful, so they may be interested in English. In the future, I am going to train some students who are weak at English after class. I hope that all the students in preschool education class 3 can make progress in this school year \\academic year. 第
