Small group instruction was assessed in a naturalistic study involving 206 observations of mathematics periods in 33 classrooms of grades 4, 5, and 6 in 21 schools. Six types of group instruction were identified, and teachers' use of such groups was explored. (SLD)

The development and field testing of two instructional mathematics programs are discussed. The general instructional program evolved from earlier research, and was field tested with 40 teachers and over 1000 fourth-grade students. Data reflected that this program had strong, positive effects on students' achievement. The second program focused on…

This book describes the Missouri Mathematics Effectiveness Project, a major systematic research program supported by the National Institute for Education. The report is based on a decade of naturalistic and experimental study of mathematics classrooms in intermediate elementary grades and junior high school classrooms. A rationale for the…

A whole-class model providing for student diversity through remediation and enrichment in small groups was compared with a two-group model accommodating diversity through fixed within-class ability groups. Higher mathematics achievement was found for the whole-class model in a study of 1,736 fourth, fifth, and sixth graders. (SLD)
