A Case Study Of Rural High School Low Cost Physical Experiment

Physics is a course based on experiment, and there is no physics without experiment.. As the physics teacher in senior middle school, the function of physics experiment should be fully played, and the quality of experiment teaching should be improved.. Now, everybody more and more attention to the low-cost physics experiments, in the middle school physics new curriculum standard ", the new lesson change for us to show the core idea is" from life to physics, from the physical to the community ", the production, living and learning activities manufactures the experimental equipment, and the things around creation experiment, life is physical, which is significance of the low-cost physics experiments.My school is a rural high school, the financial is not rich, we have developed a habit of spending less money, low-cost experiments have begun to take root in our campus.This research needs to start from the teaching, collects the side low cost, the non cost material, with the individual research skill, the study, the improvement and the innovation some low cost physics experiment. This thesis consists of 6 parts.. 1 introduction is part of the problem, analyze the subject presents the background, introduces the current situation of the research at home and abroad the low-cost physics experiments, explained the problem to be solved in the study and research of the practical value and theoretical significance. 2 Dynamics of low cost experimental case studies, including Galileo ideal slope experiment, inquiry with acceleration, force and the quality of the quantitative relation experiments, simulation of elevator, with plastic water bottles demonstration of overweight and weightlessness. 3 electrical low cost experimental case studies, including USB powered device fabrication, low power ultraviolet lamp and medium and low power red laser pointer to modify, Ampere force direction homemade studies series, "link jumps experiment", "magnetic" experiment, household appliances standby power measurement. 4 heat of low cost experimental case studies, including home-made digital microscope observation of Brownian motion, with a plastic bottle demo acting changing internal energy, electron gun salute of imitation and improvement, thermodynamic rubber band, gas stove energy-saving research of self-made. 5 Optical low cost experimental case studies, including simple optical amplification demo platform, light interference and diffraction experiment demonstration teaching aid, single slit diffraction and double slit interference study, teach you how to glasses. 6 Conclusion and introduces the teaching practice to carry out low cost physical experiment achieved results, combined with education science and psychology, in senior high school to carry out low-cost physics experiment to improve the students’ interest in learning, role in triggering the internal motivation of students to learn, for the reform of physics experiment teaching in high provides a useful reference, provides the valuable experience for high school physics teachers in the future teaching to carry out low cost physical experiment is analyzed.
