The new curriculum reform requires teachers in the classroom teaching to students as the main body, and strive to improve students 'ability to learn, develop students' scientific inquiry spirit and scientific inquiry ability. Many concepts, laws and formulas of physics, many students feel that its concept is rigorous, reasoning reasoning is difficult to understand and master, students often can not solve practical problems with the learned concepts and laws of physics, encountered computational problems Do not know which formula to choose to deal with the problem, the gradual loss of confidence in learning physics.
