Separate selection and pretesting of students eliminate regression effects in the pre-post achievement gain measured in the RMC Model--A method of program evaluation. (CP)

The measurement of change in quasi-experimental educational research was discussed. Problems related to measuring change exist to varying degrees in all research designs; these issues are less troublesome in experimental studies because the investigator can manipulate the interest variables and observe their effects on other variables. Measuring…

Twelve common errors which can invalidate an otherwise sound evaluation are identified, and ways to avoid them are presented. The hazards are: (1) grade-equivalent scores; (2) inappropriate statistical adjustments with nonequivalent control groups; (3) administering norm-referenced tests at inappropriate times of the school year; (4) inappropriate…

The measurement of change is such a broad topic that this article must limit its focus to a few specific subtopics. These specific topics include: longitudinal research design, attrition in research studies, the statistical analysis of difference scores, and the comparison of analysis of variance (ANOVA) and multivariate analysis of variance…

The Elementary and Secondary Education Act Title I Evaluation and Reporting System is a method for giving a federally funded project in reading or math an overall score on its cognitive effectiveness. This System introduced the Normal Curve Equivalent (NCE) as an aid in aggregating Title I program scores across states and nationwide regardless of…

An application of evaluation methodology to innovative educational programs through a case study of a Chicago suburban high school program for alternative education is presented. The evaluation methodology encompasses the difficulty in combining comparative programs, individual-diagnostic, and individual developmental measures, the selection of…
