Variety may be the spice of life, but in terms of data sources, variety is more than a spice--it is one of the basic food groups. Alternative data sources, such as student interviews and walk-throughs, are essential for a well-balanced diet. Data from test scores alone, whether from norm-referenced or criterion-referenced tests, state, district,…

Limiting data collection to a sample group is one way to increase effectiveness in dealing with data. The paper describes how to draw a sample group (random sampling, stratified random sampling, purposeful sampling, and convenient or opportunity sampling) and discusses how to determine the size of the sample group.

Six areas of staff development program evaluation in which participants may be meaningfully involved are: (1) clarification of the program's goals; (2) development of a design for the evaluation study; (3) development of methods for measurement; (4) analysis of information; (5) response to evaluation instruments; and (6) reporting on an evaluation…

Getting answers to questions about schools and student learning requires that educators know how to collect, analyze, and interpret data. Six critical steps in this process include: posing questions, establishing judgment criteria, making a plan, gathering data, analyzing data, and interpreting results. These steps can serve as a beginning guide…

A workshop designed to assist local staff developers with the evaluation of their staff development programs is described. The intent of the workshop is to provide specific technical assistance for implementing a planned and consistent evaluation process. The workshop's goal is to allow a nonspecialist in evaluation to gather data necessary for…

Presents a model to help schools pose and answer data-based questions about teaching and learning, describing different types of data that educators can use to piece together pictures of their schools (e.g., student learning statistics, demographic data, and school process data) and discussing how educators can cross data from different categories…

Extensive practice and research in program evaluation have led to this eight-step process that a professional developer can use to determine a program's effectiveness and strengthen the program as it evolves. An unbiased, systematic process of evaluation can help justify putting resources into professional learning and make it easier to determine…
