The Investigation About The Status Of Physics Knowledge Emerging In The Middle-school Chemistry Experiments

Chemistry is a natural science based on experimentation. The teaching effect is influenced much by the experiments that the teacher shows in teaching. For a long time the teaching status in quo is "different subject different area", each subject has its own separated system. In the chemistry teaching, the teachers used to develop the lecture focused on just one subject, only chemistry but no physics. It makes the knowledge of chemistry and physics be isolated, and become fragmentations. Especially in the teaching procedure of chemistry experiments, the teachers only regard chemistry process but say nothing on or neglect physics phenomenon and its function in the true-life. It makes the knowledge be limited and isolated, without any good to develop the students' integration capability and the science diathesis. Both chemistry and physics are the important basic subjects in nature science, they supplement each other, and the knowledge is mingled, they can not be separated from the principium or from the phenomenon. To emphasize the infiltration and integration between different subjects in middle school chemistry teaching must inspire the students' enthusiasm, go-aheadism and creativity and makes for the development of the students' comprehensive capability. Along with the New Course Reform, the popularization of "3 +X", the all-sided advance of Diathesis Education and the implement of fostering the student's science diathesis, the innovation and the ability of practice, it becomes very urgent and necessary to investigate the chemistry experimentation and its teaching theory. The reform of chemistry experimentation is an important portion of course reform and teaching reform. This paper regards chemistry experimentation as one way of chemistry research, expatiates the physics phenomenon brought by the experiments. It can not only deduce the essence of chemistry changing also make it possible to develop deeper phenomenon analysis. The aim of research about the physics phenomenon in middle school chemistry experiments is to make the teachers and the students change their single chemistry thinking, can observe, think and solve all kinds of the chemistry problems in living, producing and society, and to make them understand the status of current middle school chemistry experimentation teaching correctly, analyze the problems in current middle school chemistry experimentation teaching, look after and quest for the way to settle it. It emphasizes fully the teachers should look for the knowledge joints of mixed subjects based on the textbook, and according to the joints design transferring training to develop the students' transferring ability and the sense of amalgamation, guide the students to use different subjects' knowledge and methods to solve the chemistry problems. Not only the chemistry process but also the physics knowledge in the chemistry process should be think much of and be taught, in order to lead the students' innovation thinking, make it possible to let the students learn more different subjects knowledge from one experiment, and further develop their all-sided systemic research spirit, help the teachers and the students get out of the hedge of close-in education system to satisfy the request of the Entrance Examination Reform and the Diathesis Education by means of infiltration and cooperation.
