A pretest-posttest design for measuring the effects of educational programs uses comparison groups consisting of pupils like those in the treatment group but not getting that particular treatment. Although the design is geared primarily to evaluation of Title I programs in large cities, it should also apply to other situations. The plan for…

The purpose of this paper is to demonstrate the use of the general linear model (GLM) in problems with repeated measures on a dependent variable. Such problems include pretest-posttest designs, multitrial designs, and groups by trials designs. For each of these designs, a GLM analysis is demonstrated wherein full models are formed and restrictions…

The purpose of this study is to describe and compare the performances of students in a beginning course in educational statistics. Modified mastery learning strategies such as the use of a pretest, diagnostic tests, parallel midterms, and an extended time allowance to master the content were employed during the course. Data was available on 359…

A total of 28 advantaged and 28 disadvantaged 5-year-old children who had been tested in a previous study designed to measure some of the skills and characteristics thought to be related to academic success (ED 032 929) were retested after a 6-month interval during which they had had a preschool experience. Two measures of object exploratory…

Describes a diagnostic mathematics test used to indicate the mathematical weaknesses of engineering students. (MLH)

Four preinstructional strategies are defined as to their current usage, the separate research on each concept is reviewed and the total findings are summarized into procedural guidelines. (Author/DEP)

Forty-two student teachers were asked to evaluate the effectiveness of teachers based upon statements of authoritarian or nonauthoritarian teaching philosophy, both before and after their student teaching experience. Results were compared to see if attitudinal changes had occurred. Findings are discussed in light of previous research. (Author/MT)

Because of limitations in simple gain scores, pychometrists have proposed alternate methods for measuring change, two of which are residualized difference and base-free change. This paper provides large sample empirical estimates of the reliability these change measures. It checks theoretical predictions derived from inequalities involving all…

Analysis of naturalistic data identified features of adult-child talk which occurred frequently at school but rarely at home. One of these features--question sequences intended to elicit an answer--was used in an intervention study and was found to promote young children's understanding of ambiguity in verbal messages.

A simple quasi-experimental design is described which may have utility in a variety of applied and laboratory research settings where ordinarily the one-group pretest-posttest pre-experimental design might otherwise be the procedure of choice. The design approaches the internal validity of true experimental designs while optimizing external…

The purpose of this study was to investigate normal, 40 percent compressed, and 80 percent compressed speech presentations of conceptual data for the "Burns" chapter from the Multimedia Standard First Aid book. There were overall differences among posttest scores attributed to presentation method adjusted, in an analysis of partial variance, for…

Pre- and posttest scores of students of four introductory educational psychology classrooms were analyzed in order to find differences in achievement associated with a cooperative goal structure versus an individually competitive goal structure. Results are discussed. (Author/MT)

This paper gives a mathematical treatment to findings of Zimmerman and Williams and establishes a minimum reliability for gain scores when the pretest and posttest have equal reliabilities and equal standard deviations. It discusses the behavior of the reliability of gain scores in terms of variations in other test parameters. (Author/LMO)

Skilled and less skilled beginning readers (n=54) were taught to read and define 10 printed pseudowords. Post-tests revealed that experimentals retaining spellings in memory as orthographic images remembered spellings better than controls who received comparable training without the memory component.
