Study And The Practice Of Classroom Teaching On The Principle Of Electromagnetic Car

Now the primary purpose of basic education in China is mainly to cultivate and enhance students' examination ability,but it has not pay enough attention to the cultivation of students' comprehensive ability.In view of this situation,the inquiry teaching method,which adopts simulating the process and method of scientific research,emphasizes the students' autonomy and initiative,and concerns in the development of the core literacy of the students has been focused in this article.A case of the electromagnetic car has been developed and a thorough inquiry on it has been carried out.Thus,the motion principle of the electromagnetic trolley is concluded.That is,the closed loop current with battery,magnets and solenoid produces a magnetic field in the solenoid,and it interacts with the magnets' field.Besides,some details about success or failure of the experiment also have been explored.On the above basis,an inquiry teaching of the case has been carried out in a middle school class with the self-made equipment.The course of the class and the author's think have been recorded.It is found that the most of students are deeply involved in the class-room,and they hope to have more similar classes in the future.And inquiry class can improve the students' comprehensive ability of hands-on,exploring,finding and analyzing problems.
