ALEKS
An adaptive learning platform using Knowledge Space Theory to accurately assess and teach math, science, and business courses.
Overview
ALEKS (Assessment and Learning in Knowledge Spaces) is one of the longest-running AI-powered adaptive learning systems, built on the mathematical framework of Knowledge Space Theory. It uses adaptive questioning to rapidly determine what each student knows and does not know, then creates a personalized learning path through the material. ALEKS is widely adopted in K-12 schools and universities for math placement testing and course delivery, serving millions of students annually.
