Has anyone actually ever.....

Brian,

I have used a site called ALEKS for math study supplementation. My son uses it also to help tutor him through math concepts. Check it out. From the ALEKS site (www.aleks.com):

[SIZE=3][SIZE=3][SIZE=2]ALEKS is a revolutionary Internet technology, developed at the University of California by a team of gifted software engineers and cognitive scientists, with the support of a multi-million dollar grant from the National Science Foundation. ALEKS is a Web-based, individualized learning assistant. Utilizing a sophisticated artificial intelligence engine, ALEKS currently helps people learn a number of subjects in mathematics and business. ALEKS uses its unique, state-of-the-art assessment technology to identify precisely what each individual already knows, and what is now ready to be learned.[/SIZE][/SIZE][/SIZE]

ALEKS always offers a selection of material for which the individual learner is well-prepared. The highly targeted instruction provided by ALEKS enables immediate success -- in learning new subjects -- and in refreshing and increasing knowledge in subjects that have been studied before.

ALEKS is the new way to learn math on the World-Wide-Web. By knowing exactly which math concepts the student has mastered, which are shaky, and which are new but within reach, ALEKS enables the student to work on those concepts the student is most ready to learn. ALEKS is a full-time automated tutor, including explanations, practice and feedback. ALEKS closely interacts with the student, continuously updating its precise map of the student's knowledge state. ALEKS combines the advantages of one-on-one instruction and evaluation with the convenience of being on-call, on your computer, 24 hours a day, seven days a week.

ALEKS is fundamentally different from previous educational software. At the heart of ALEKS is an artificial intelligence engine -- an adaptive form of computerized intelligence -- which contains a detailed structural model of the multiplicity of the feasible knowledge states in a particular subject. Taking advantage of state of the art software technology, ALEKS is capable of searching an enormous knowledge structure efficiently, and ascertaining the exact knowledge state of the individual student. Like "Deep Blue," the IBM computer system that defeated international Chess Grand master Garry Kasparov, ALEKS interacts with its environment and adapts its output to complex and changing circumstances. ALEKS is based upon path breaking theoretical work in Cognitive Psychology and Applied Mathematics in a field of study called "Knowledge Space Theory." Work in Knowledge Space Theory was begun in the early 1980's by an internationally renowned Professor of Cognitive Sciences who is the Chairman and founder of ALEKS Corporation.

Students use ALEKS to learn math in more than two hundred US colleges and school districts. More than 3,000 students log on to ALEKS every day, and more than 10,000 assessments take place each month.

It is a great site that will help you shore up your weak areas in math.
