The "I CAN Learn[R] Pre-Algebra" and "Algebra" computerized curricula are designed to cover mathematics and problem-solving skills for ethnically diverse, inner-city students in grades 6-12. The curricula are designed to equip students with the skills they need to meet district, state, and national math objectives through an interactive software program that teaches pre-algebra and algebra. The "I CAN Learn[R] Pre-Algebra" software program consists of 131 lessons, and "Algebra" of 181 lessons. The developer describes the curriculum software as meeting National Council of Teachers of Mathematics standards and configurable to meet state and local grade-level expectations. One study of "I CAN Learn[R] Pre-Algebra" and "Algebra" met the What Works Clearinghouse (WWC) evidence standards and five more studies met WWC evidence standards with reservations. The six studies, which included more than 16,600 eighth- and ninth-grade students in middle and high schools in California, Florida, Georgia, and Louisiana, compared the standardized math performance of students who used the "I CAN Learn[R]" system with that of students who used traditional curricula. The "I CAN Learn[R] Pre-Algebra" and "Algebra" curricula were found to have positive effects on math achievement. (Contains 11 tables and 9 footnotes.)
