The Virginia system is betting on that promise. Its colleges will soon replace their semester-long developmental-math courses with nine units, which can be taken as one-credit classes or Web-based lessons with variable credit hours that allow students to complete more than one unit in a self-paced computer lab and classroom.
The number of units that students are required to complete will depend on their placement-test scores and intended program of study. Students focused on the liberal arts will have to show competence in only five units, for example, mastering basic algebra concepts such as linear equations. Students who plan to pursue careers in science, technology, engineering, math, or business administration must complete all nine units.
