Abstract
West Virginia is piloting the WVEB Algebra course in
several sites throughout the State in the fall of 2000. Students in the
course will receive both high school and university mathematics credit.
Interactive computer laboratories make up a significant component of the
course. The laboratories are being rewritten in html and make use of Java
applets. This will enable delivery of the laboratories to a variety of
platforms over the web and from CD's through a standard web browser. Currently
the laboratories are written in MathWright, which requires a runtime interpreter.
In order to rewrite the laboratories and develop new laboratories in html,
a versatile graphing Java applet is necessary. In 1999, a prototype was
developed that graphed a fifth order polynomial. The graphing engine proved
to be stable and flexible. The new feature of the applet is an equation
parser. The parser allows up to three equations to be entered directly
and graphed. Additionally, points can be plotted on the graphing screen
and tables can be generated from the equations.
