In Secondary School Physics Teaching Practice Of The Second Law Of Thermodynamics

The education purpose of technical school is to cultivate well-trained labors and junior and mid level technical personals for industry and service. Such schools seem to be a interchange station for personals .Physics is of great importance for the students' characteristics in their scientific thinking .As science and technology develop and the society progresses, the education system should be constantly amended, and the students should master the relevant knowledge about physics.In this essay the author first analyzes the significance and the microcosmic explanation of the Second Law of thermodynamics, and states its position and function in details in the field of computerized telecommunication. By combining the present situation of physics teaching at middle school in China, and the importance of the Second Law of thermodynamics in today's information society, the author puts forward her point of view. According to the psychological characteristics of the technical school students, the author concludes in this essay that good result can be achieved to teach the Second Law of thermodynamics by using Introduction-Discussion method, which arouses the students' interest to learn physics as well. During the assumed experiment, the students form their small groups for doing the experiment and they are chosen as the controlled ones all at random. Then they are supposed to be tested afterwards. And the non-relevant elements are strictly eliminated .The marks of the students' mid-term exam are used as the reference, different teaching methods are being adopted and their process being checked, and the marks abtained from the check are used as the operational concept, then the obtained data be diagrammatized. The by comparing the above steps, the author reached the following concluding: it is practical and feasible to the Second Law of thermodynamics, comparatively good teaches result will be achieved by using Introduction-Discussion method, it is beneficial to the students' technical knowledge, it stirs up the students enthusiasm in learning and it is of great significance both theoretically and practically.
