The Chapter 1 Corrective Mathematics program provided supplementary, individualized instruction in mathematics using both face-to-face instruction and computer-assisted instruction (CAI) for eligible students attending nonpublic schools in New York City. The objective for the 1988-89 Corrective Mathematics Program was that students would achieve statistically significant mean gains in normal curve equivalents (NCEs) on standardized tests. This document provides the findings of this evaluation based on data from document reviews, analyses of mean gains on standardized test scores, site visits, interviews with program teachers, and analyses of the CAI teacher survey given to 20 CAI teachers. The following items are included: (1) a brief introduction to the program and the program evaluation; (2) a program description; (3) a discussion of the program implementation; (4) the results of the CAI teacher survey; (5) a summary of student outcomes; and (6) conclusions and recommendations. Appendices include a description of the Chapter 1 Nonpublic School Reimbursable Services, 1988-89; and a copy of the Computer Assisted Instruction Teacher Survey. (KR)
