Aleks Math

Aleks Math is an online math program for grades 3-12.  It normally costs $200 per user per year, but this year, Keystone is signed up as a K-12 school through Aleks Math, so it only costs $40 per student per year, plus $2 account creation fee.

From the website:

ALEKS is a ground-breaking technology developed from research at New York University and the University of California, Irvine, by a team of software engineers, mathematicians, and cognitive scientists with the support of a multi-million-dollar grant from the National Science Foundation. ALEKS is fundamentally different from previous educational software. At the heart of ALEKS is an artificial intelligence engine that assesses each student individually and continuously.

ALEKS is based upon original theoretical work in a field of study called "Knowledge Space Theory." Work in Knowledge Space Theory was begun in the early 1980's by Dr. Jean-Claude Falmagne, an internationally renowned mathematician and Professor of Cognitive Sciences who is the Chairman and founder of ALEKS Corporation.

How does ALEKS work?

ALEKS avoids multiple choice questions and instead uses flexible and easy to use answer input tools that mimic what would be done with paper and pencil. When a student first logs on to ALEKS, a brief tutorial shows him how to use these ALEKS answer input tools. The student then begins the ALEKS Assessment. In a short period of time (about 45 minutes for most courses), ALEKS assesses the student's current course knowledge by asking him a small number of questions (usually 20-30). ALEKS chooses each question on the basis of his answers to all the previous questions. Each student, and therefore each set of assessment questions, is unique. It is impossible to predict the questions that will be asked.

By the time the student has completed the assessment, ALEKS has developed a precise picture of her knowledge of the course, knowing which topics she has mastered and which topics she hasn't. The student's knowledge is represented by a multicolor pie chart.
