The Pasco ScienceWorkshop 750 Interface can be used to take data from over fourty different sensors. The data can be displayed in a variety of way on the video projectors. Many of the demonstrations can use the interface to create a more interactive teaching enviroment. An example of a method for increasing classroom using real time data gathering and analysis is the Interactive Lectue Demonstrations (ILDs) originally written by Sokollof and Thornton. Others have now extended their work.
