提高化学课堂导入的有效性（Improving the effectiveness of chemistry classroom introduction）

提高化学课堂导入的有效性（Improving the effectiveness of chemistry classroom introduction） As the saying goes, a good beginning is half done. A good beginning of a class is like a good play, a good news, a good melody, a good overture. Start well, can cause the head start, students are eager to pursue new knowledge of the mental state, arouse their interest in learning, attention. But into the new class of selected content must be subject, not from the regular theme. Otherwise, it not only does not help to understand the new knowledge, but also interferes with the students understanding of the new course, and causes the obstacle to the students cognition process. It should import the teaching situation of students like, to attract the attention of students, stimulate students mind, they start thinking, but also pay attention to the effectiveness of import, avoid, even the phenomenon of a remote from the subject. Now, according to years of teaching practice, I talk about several ways of introducing new chemistry courses. I. Introduction of emotion A harmonious environment, a good atmosphere, so that students have a happy mood into the study, this is effective guarantee classroom. A good beginning can shorten the distance between teachers and students, create a good atmosphere for the whole class, and make the whole class teaching harmoniously and naturally. Let the whole classroom carry on under the equal democratic atmosphere, strengthen students receptivity and participation, and lay a good foundation for efficient classroom. For example, in the teaching of chemistry in the nature of molecules, you can first set up a question that students think is very simple and naive, 50+50=? Then, to guide students into the 50+50 = 100 inquiry experiment. It is easy for students through the experiment 50 ml ethanol mixed with 50 ml of water volume less than 100 ml results, however, students do not know why the 50+50 is not equal to 100. At this point, if the teacher directly into the tradit
