The Chapter 1 Corrective Mathematics Program provided supplementary mathematics instruction to Chapter 1-eligible students in New York City nonpublic schools. Its goals were to strengthen students' understanding of mathematical concepts, to improve their ability to perform computations and solve problems, and to assist them in applying the knowledge and skills gained to everyday life. This document reports on the implementation and evaluation of this program as carried out since the 1986-87 school year. The report is divided into five chapters. The introduction provides background information on the program, information on eligibility, program objectives, program evaluation, and the scope of the report. Chapter II describes the organization and implementation of the program providing information on the number of students served, type of instruction, including computer assisted instruction. Chapter III describes the parental involvement in the program. Chapter IV reports the student achievement outcomes. Chapter V reports the conclusions and recommendations made by the program. It is suggested that the program increase parental contact at the high school level, coordinate Corrective Mathematics parent workshops with other Chapter 1 instructional programs to maximize parental participation, assess the feasibility of publishing the "Parent Involvement Booklet" in French and Spanish, and expand the Pilot Computer Take Home Project to permit a valid evaluation of its effects.
