Information technology and the advances made from 1993 to the present have unified the participants in STEP. Lessons and hands-on practice during that first summer began with the introduction to electronic mail, using elm, and ftp and gopher, for communcations and information retrieval on the Internet through computer accounts graciously donated by UCSD and CERFnet. Teachers were also given an overview of how programming languages work and the MATLAB computational environment. NCSA Mosaic was demostrated to the participants on February 5, 1994, and a new era in Information Technology began. The impact of the World Wide Web on STEP grew over time and in 1996 has become the main tool for information sharing. Don Anderson began developing materials for using Web browsers, HTML, and helper applications such as NIH Image or spreadsheets, to present classroom lessons on stand-alone computers. The key here was taking advantage of Web technologies without an Internet connection. Extensive instructions for doing this are at the STEP home page: http://www-step.ucsd.edu/s95 STEP teachers now use the Web browsers to give presentations of their work to their peers, as well as guide student explorations in the classroom.
