University of Chicago School Mathematics Project (UCSMP) Algebra is a one-year course covering three primary topics: (1) linear and quadratic expressions, sentences, and functions; (2) exponential expressions and functions; and (3) linear systems. Topics from geometry, probability, and statistics are integrated with the appropriate algebra. Problem-solving and real-world applications are used throughout to develop and maintain basic skills and concepts. Computer algebra system (CAS) technology is used in the classroom to aid in the development of properties and skills, and graphing calculators are used to complete assignments at home. Thirteen studies reviewed by the What Works Clearinghouse (WWC) investigated the effects of UCSMP Algebra. Twelve studies do not meet either WWC evidence standards or eligibility screens. One study of UCSMP Algebra meets WWC (WWC) evidence standards with reservations: based on this one study, which found that UCSMP Algebra had no discernible effects on math achievement, the WWC considers the extent of evidence for UCSMP Algebra to be small for the math achievement domain. The conclusions presented in this report may change as new research emerges. Five appendixes are included: (1) Study Characteristics; (2) Outcome Measures; (3) Summary of Study Findings; (4) Rating; and (5) Extent of Domain. (Contains 8 footnotes. Appendixes are footnoted individually.) [The following study is reviewed in this intervention report: Peters, K. G. (1992).
