Programs that improve teaching effectiveness represent a core strategy to improve student educational outcomes and close student achievement gaps. This article compiles empirical values of intraclass correlations for designing effective and efficient experimental studies evaluating the effects of these programs. The Early Childhood Longitudinal…

Restorative practices in schools lack rigorous evaluation studies. As an example of rigorous school-based research, this article describes the first randomized control trial of restorative practices to date, the Study of Restorative Practices. It is a 5-year, cluster-randomized controlled trial (RCT) of the Restorative Practices Intervention (RPI)…

This article provides an overview of the PLA program at a large public U.S. institution and presents the findings of the…

The study evaluated the objectives of the Universal Basic Education (UBE) programme in Delta State. It considered the extent to which each objective was achieved. A research question on the extent to which the UBE objectives were achieved guided the study. Two hypotheses were tested. A sample of 300 students was randomly drawn through the use of…

Written by a social worker for social work students, this is a nuts and bolts guide to statistics that presents complex calculations and concepts in clear, easy-to-understand language.

This guide to program evaluation presents questions that illuminate aspects of the evaluation process. Issues to consider in program evaluation are: (1) the intended results of the program; (2) hypotheses about the possible results of the program; (3) the types of data that will indicate achievement of the intended results and the variables that…

Hypothesis generation and testing is outlined as an additional domain for program evaluators. Program evaluation involves a thorough analysis of the processes that contribute to change (or a lack of change) among program recipients. This process of change is analyzed in two ways: (1) treating programs as naturally occurring field studies; and (2)…

A field study to describe common characteristics of three "most successful" vocational programs in each participating northern California community college is presented. The study was divided into distinct phases. In Phase I, a procedure for identifying three "most successful" programs on each college campus was developed and…

Identifies the purpose and need for a vocational evaluation process in the correctional setting. Discusses the five steps in such a process: preliminary intake procedure, primary data gathering, hypothesis formulation phase, hypothesis testing phase, and outcome and/or follow-up. CCT)

The Naturalistic Evaluation Methodology presented here rests on a transactionist theory of child development, an ecological view of human behavior and the quasi-clinical method of inquiry. It is intended that the procedures will lead not only to the improvement of the quality of preschool education but will generate knowledge about children's…

The linked judgments approach is offered as a potential solution to problems of statistical conclusion validity when judges' ratings are employed in pretest-posttest designs. (Author/GK)

A major problem in social science research is that of successfully carrying out the random assignment of persons to experimental and control groups. In this study a computer-based random assignment procedure operated successfully on a weekly basis for 17 consecutive weeks in a program serving over 360 ex-offenders. (CTM)

The popularity of semestered timetable organization is founded on the belief that this organizational change makes a positive contribution to the social, emotional, and cognitive growth of students. This research attempted to test the validity of that belief by identifying the claims made for timetable reorganization, formulating these claims as…
