Study On Examples Of The Modular Of The Principle Of Chemical Reaction

The modular of the principle of chemical reaction, this part of knowledge is very abstract .It is difficult for students to understand. Examples are often been considered as an effective teaching method by teachers. The premise of appropriate example is the correct understanding of the knowledge.This paper is researching examples of the modular of the principle of chemical reaction in chemistry class-teaching. Take the example of the direction of chemical reaction because of its abstraction. Firstly,analyse several issues,such as the number of examples, the number of teachers, examples by knowledge-points,the sources of examples and the proportion of positive and negative examples in this lesson in four teachers'classes.In order to try to show the application status of examples in chemistry teaching in high school. Additionally, offer some suggestions in a targeted manner for examples in chemistry class-teaching in high school,combining the status of examples. Such as: in class-teaching, teachers should give more chance to students to make examples.Teachers should hold the proportion appropriately: examples in the textbook and examples not in the textbook, examples of subject knowledge and examples of not subject knowledge.Next, this paper also parses the problems in several aspects in the process of taking examples combining specific content. Thus arrive at a conclusion that there are some contradictions in the process of turning the abstract theory into concrete examples,so that the examples do not explain its abstract theories correctly. It is the fundamental way to solve this problem that teachers understand professional knowledge deeply. Thus, It emphasizes that a solid professional knowledge is the basic requirement for teachers and it is the most fundamental and most important quality of the quality of teachers.This paper is based on case study and test study,using the observation, interview and other research methods.
