Courses in elementary, middle school, high school, college prep, and college mathematics are offered by the Web-based ALEKS (Assessment and Learning Knowledge Spaces) program. The system features individually-targeted instruction correlated to Common Core and state standards. Using ALEKS, students work at their own level, a level determined by ALEKS artificially intelligent assessment techniques. The system selects questions based on students’ previous answers and then presents topics students are ready to learn. ALEKS assesses progress periodically to make sure students are mastering and retaining content. To find out more about ALEKS courses and assessment, take an ALEKS tour or sign up for a free trial.
