The course objective is to develop mastery of math concepts and operations using guided, assessment-based study in the ALEKS system. Following an initial assessment, students are given the choice of topics for active study based on individual current readiness; as progress is made, the selection of topics evolves according to developing readiness. Interactive feedback, step-by-step explanations, and hyperlinked dictionary definitions support active mastery of new material. Periodic reassessments confirm mastery and ensure adequate ongoing review; students can also review spontaneously. Real-time reporting of progress is visible to students.
