Research On Applying The Multimedia Technology To The Readiness Lesson Before Physical Experiment In High School

The new curriculum criticalness of physics in high school has made it's discipline, which calls for students'ability of physical experiment. It's basic ability requirements include: understand the purpose of experiment, be able to use the condition that has been owned, choose as good as method, devices and equipments, make plan and design experiment. So far, the physical experiment-teaching has not yet achieved the requirements. As a result of the useless results of the readiness lesson before physical experiment, many students really not understand and grasp the contents of experiment principles and the instruments deeply before they get to the lab, all of which lead to a not so good phenomenon: Some students usually make mistake in operation procedure, someone may mishandle the instrument, some even copy their classmates'results. As the inefficient teaching of physical experiment for a long time, not only students but also teachers seem to lose their way. So most of the learning ways in physical experiments still stay at the level of looking teachers'operating or the presentation by multimedia, then students go to labs and imitate experiment procedures. Because students just copy the ways that teachers taught, they don't need think by themselves, so limit experience of exploration, which would take disadvantage on cultivating the capability of the experiments designing.The research of the theory and the practice found that the efficiency of physical experiment-teaching can be improved through the readiness lesson before experiment. Depending on the physical experiment-teaching's achievement has been made in the academic and the practical field on the assistant of the multimedia technology, This article bring forward the multimedia technology to the readiness lesson of physical experiment, trying to design partly multimedia animation in the aim of elevating the effect of the readiness lesson before physical experiment,at the same time, resolving the problems in existence in physical experiments-teaching. This is important to realize that the multimedia animation in this article are designed in the purpose of helping students for experiments-preparing, but not a presentation of experiments once more, The multimedia animation are designed on the basement of the students'cognitive structure and the content of experiments, aim at the difficulties in students'understanding. According to the different situation of each readiness lesson, make differences the actual content would contain the structure and working principle, the physical principle of experiments and so on.Analyzing the materials and learning teaching experience from the first-line teachers, the author select out some presentation of physical experiments, then design and accomplish the multimedia animation. Finally apply those achievements to the teaching practice, check and demonstrate the results of the research, also make further efforts to enhance and improve the multimedia animation.
