The Application Of Digital Information System In Innovative Physics Experiments

To foster persons with ability of innovation is the important mission of education given by the new age.Innovative physics experiment plays a very important role in mobilizing students' initiative,enthusiasm and creativity as well as in inspiring students' innovative thinking and innovative awareness,but due to its openness and big difficulty in design,innovative physics experiment is difficult to be effectively carried out in schools.New educational concept calls for new teaching methods,new teaching methods call for new technique to support,the appearance of digital information system has provided technical support for solving the problem discussed above.Digital information system set physical measurement,data recording and intelligent data analysis functions together,if we apply it to innovative physics experiment,not only can it makes a lot of creative experimental design to achieve,it can also significantly shorten the experimental cycle,which can promote the innovative physics experiment to be carried out effectively.Based on this idea,we have done some concrete innovative research in the mechanics and electromagnetics experiments considering the unique advantages of digital information system and we have redesigned some experiments using Llongwill DISLab.We've redesigned the experiment of measuring the acceleration due to gravity,the new experiments have reduced the impacts due to experimenters' subjective factors on the aspects of time recording,the three new experiments were designed to be more reliable and easier to operate step by step;Based on the experiment of measuring the acceleration due to gravity using micro-current sensor,we conducted a further inquiry, and designed a method for the quantitative verification of Faraday's law of electromagnetic induction,while most of the traditional expenments were generally qualitative observation of the phenomenon of electromagnetic induction.These experimental designs have highlighted the "teacher-instructing" and "studentconducting" experimental methods,and have provided some good examples of how to use digital information system for innovative physics experiment.
