A district-level reform model created by the Center for Data-Driven Reform in Education (CDDRE) provided consultation with district leaders on strategic use of data and selection of proven programs. Fifty-nine districts in seven states were randomly assigned to CDDRE or control conditions. A total of 397 elementary and 225 middle schools were…

Using a cluster randomization design, schools were randomly assigned to implement Success for All, a comprehensive reading reform model, or control methods. This article reports final literacy outcomes for a 3-year longitudinal sample of children who participated in the treatment or control condition from kindergarten through second grade and a…

This article reports literacy outcomes for a 2-year longitudinal student sample and a combined longitudinal and "in-mover" (i.e., those students who moved into the study schools between the initial pretest and the second-year posttest) sample, both of which were nested within 38 schools. Through the use of a cluster randomization design, schools…

Data were collected in 51 desegregated high schools, to determine what school practices improved racial attitudes and behaviors. Results indicated that programs involving cooperative interaction among students of different races were most likely to lead to positive race relations. (Author/MH)

The consequences of using alternative measures of time and achievement are examined in an observational study of 18 elementary school classes. The extent to which choice of the same model linking time and learning for all students was implicated in the inconsistent results is examined. (Author/GK)

Achievement and attitudinal effects of three mathematics instruction methods directed in varying degrees toward accommodating diversity in student performance levels were compared in two randomized field experiments with third- through sixth-grade classes. Treatments included Team Assisted Individualization, Ability Group Active Teaching, the…

First-year outcomes are reported for Success for All--a program designed to bring all children to grade level in basic skills by the third grade. The program uses one-to-one tutoring, reading methods, frequent assessment, enhanced preschool and kindergarten programs, family support, and other interventions to prevent learning problems from…

The cooperative elementary school model uses cooperation, particularly cooperative learning, as a philosophy for educational change. A 2-year study of the cooperative elementary school model in 2 treatment and 3 comparison schools involving 1,012 students demonstrates positive effects on academic achievement and social relations.
