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…

Supplemental Instruction (SI) is a voluntary, non-remedial, peer-facilitated, course-specific intervention that has been widely demonstrated to increase student success, yet concerns persist regarding the biasing effects of disproportionate participation by already higher-performing students. With a focus on maintaining access for all students, a…

For RCTs of education interventions, it is often of interest to estimate associations between student and mediating teacher practice outcomes, to examine the extent to which the study's conceptual model is supported by the data, and to identify specific mediators that are most associated with student learning. This article develops statistical…

For international service-learning to thrive, it must document student learning outcomes that accrue to participants. The approaches to international service-learning assessment must be compelling to a variety of stakeholders. Recent large-scale projects in study abroad learning outcomes assessment--including the Georgia Learning Outcomes of…

The relationship between the importance of the objectives of a public school reading program and the extent of data collection efforts pertaining to these objectives was examined. The purpose of the study was to determine if the information collected was sufficient for teachers to make a continuous evaluation of the program's ability to meet the…

A practical application of generalizability theory, demonstrating how the variance components contribute to understanding and interpreting the data collected to evaluate a program, is described. The evaluation concerned 120 learning modules developed for the Dental Auxiliary Education Project. The goals of the project were to design, implement,…

Since the first edition of "Schools and Data", the No Child Left Behind Act has swept the country, and data-based decision making is no longer an option for educators. Today's educational climate makes it imperative for all schools to collect data and use statistical analysis to help create clear goals and recognize strategies for…

Describes the development of an instrument for evaluating building-level school library media programs based on "Information Power," the American Association of School Libraries' guidelines for such programs. Data collection at an Oklahoma teleconference is described, the use of factor analysis is explained, construct validity is…

This guide is essentially designed as a teaching aid for those who would inform planners, officials of educational ministries, school administrators, principals, and teachers about educational outcome measurements. In outline and graphic form, the guide presents topics for discussion in a seminar dealing with the application of outcome…

A model for educational supervisors which attempts to link management theory to learning is demonstrated. With teachers today having greater autonomy in selecting appropriate content and methods, supervisors should focus on two tasks: they should become more involved with teachers in selecting goals and become more adept in monitoring the…
