Ti Graphing Calculator-based Physical Design Of Experiments And Experimental Data Processing Software

Design of Physics Experiment based on TI Graph Calculator and Development of Experimental Data Processing Software utilizes advanced experimental instruments - TI Graph Calculator and CBR (Calculator-Based Ranger) or CBL (Calculator-Based Laboratory) ,and computer to research on Experiment Physics Teaching. It could make up the shortage of evincive experiment in physics teaching in high school. The research proves that the experiment tools and data processing means could fit the need of Experiment Physics Teaching in high school, and they provide a useful educational means for physical teaching and learning in high school.The experiment tools used in the article is a set of teaching instruments developed by TI company in U.S.A. They include TI Graph Calculator, Basic Laboratory based on TI Graph Calculator and some sensors/probes. Using this set of TI tools and technologies, we could gather many types of experimental data quickly, expediently and truly. And then, we could transfer the experimental data to TI Graph Calculator, make mathematic analyse and draw the conclusion. We take the advantage of data gathering of this set of instruments to gather many data about displacement, velocity and acceleration during the spring vibrating on real-time. Furthermore, these data provide abundant data-resource for the design of Experiment Physics Teaching.In the part of experimental data processing, I use the software developed by myself in Delphi. The primary function of the software is to fulfil curve fitting with the data that are gathered in the experiments according to several basic mathematic models. By testing, this software has better dependability. It could not only meet the need of the data processing precision in Experiment Physics Teaching, but also make up some shortage of TI Graph Calculator, such as worse precision, complicated operation and so on. At the same time, this software also improves the teaching pertinence.Design of Physics Experiment based on TI Graph Calculator and Development of Experimental Data Processing Software provides a whole example of instructional design. And that, the data processing software developed also provides a kind of reliable teaching means and learning tool which are easy to use. Of course, there has much shortage in the method of Experiment Physics Teaching. But with the development of the instructional theory and means, the research on Experiment Physics Teaching will be made progress!...
