However, as my father was fond of saying, 'The tool is only as good as the person operating it.' Use at your own risk. I am confident that the programs are sound. Please remember that no program is a substitute for comprehension of underlying theory. You will need an unzipping program, and a TI link cable and the TI-Connect program for your computer. All of the programs are are in zip archives, with a simple readme file. Below I have linked to some useful programs, most of which I have written or modified. In addition, many calculations can be simplified (once the theory is mastered) by use of calculator programs. They are used in conjunction with the lab component, where we do many labs with the Vernier LabPro and Vernier probes. The TI-83plus/TI-84plus graphing calculators are used extensively in our AP Chemistry program.
