The problem of educational evaluation, the various types of evaluation, and the different kinds of models of evaluation systems are discussed in some detail. The educational needs of the students, staff, community, and the Philadelphia Title I schools, as agreed by members of the evaluation team, are listed. A taxonomy of Title I evaluation is…

In Dyer's Student Change Model, performance indicators (PIs) are utilized as a measure of the effectiveness of educational programs. These PIs are examined and analyzed in some detail in this paper. In particular, the reliability of the residuals, the sensitivity of the measure to sample size, the random half reliability, and the stability of the…

Evaluation is discussed as an information-gathering process. Currently popular evaluation programs are reviewed in relation to decision making and various approaches that seem to contribute to the decision utility of evaluation (e.g. classical approaches, Bayesian approaches, adaptive designs, and model-based evaluations) are described.

It may be useful in evaluation research to employ the class as the unit of analysis, assessing its syntality by a vector of distribution cumulants or indices for each of several input tests administered. (Author)

The Data Envelopment Analysis (DEA) model, a conceptual model for measuring productivity and efficiency, is presented and applied in this report. First, the DEA model is described, and three of its properties that make it particularly useful are identified; i.e., it measures efficiency of units relative to each other rather than to absolute…

Two related problems are discussed: developing a methodology which (1) will not require full commitment of a local education agency to new techniques which may be ineffective in local settings and (2) will allow graceful abandonment of a new technology that may be proved ineffective. An example is discussed. (CTM)
