A program description and sample program materials of a self-paced, individualized mathematics program designed to improve the achievement of junior high school students are presented. The usual daily activities of the students include a quiz, work in drillbooks, and work in the Basic Skill Levels curriculum--the heart of the program. Each of the 26 sequential Basic Skill Levels includes a pretest, four to 14 lessons, quizzes (checkpoints) after each fourth lesson, and a posttest. Students must successfully complete the level they are on before proceeding to the next. Group instruction is provided by weekly Enrichment Day activities which employ filmstrips, manipulative materials, motivational games, and worksheets. Among the reported results of the program are an increase in 1982-83 seventh-grade achievement on the Comprehensive Test of Basic Skills (CTBS) of 3.4 months for each month of instruction. Materials provided in this document include: (1) descriptions of the daily classroom routine, the math office, and Enrichment Day; (2) lists of program goals and achievement test results from 1977-1983; (3) descriptions of program components and procedures; (4) sample grade sheet, quiz, pretest, lessons, checkpoint, posttest, student profile sheet, final exam, drill sheets, and progress reports; and (5) CTBS scores and evaluations.
