The current teaching goals are all three-dimensional goals, knowledge and skills, processes and methods, emotional attitudes and values. The design of test questions mainly aims at the first two goals, and the third goal should be cultivated in the process of practice.

If it is a new class, the questions in the class should be divided into three levels: basic clearance, consolidation and improvement, and comprehensive application. Basic relationship with nature is the most basic definition and formula, and the direct application of definition and formula; Consolidation and improvement are based on basic skills, variant training and comprehensive application of learned knowledge, so we should pay attention to the application and comprehensive application of knowledge in practical situations. At the same time, we should pay attention to the control of the number of test questions in class, which is not easy to be too big.

At present, we should pay attention to the choice of exercises, which should not only conform to the teaching content of this class, but also not exceed the content and students' acceptance ability.
