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 study compares the content retention by students who are self-paced with content retention by students whose pacing is modified by instructors. The subjects included 148 students enrolled in an introductory college level child development course. One group of 74 students was randomly assigned to a self-paced section and another group of 74…

Marx, Thomas – 1973
When two groups, initially dissimilar, undergo different treatments, can subsequent differences be partitioned in such a way that the difference between the two treatments is unbiased? This is the central problem of this paper, and it is confronted by the examination of two levels of information using a Follow Through Evaluation. The first…

Weber, Larry; Fleming, Dan – 1978
A project to upgrade knowledge and skills of junior high school students in American history was conducted in four cities and counties in Virginia during 1977-78. The hypothesis was that students who received feedback from teachers regarding performance on an American history pre-test would perform better on a subsequent American history test.…
