A quasi-experimental research design with quantitative and qualitative methodologies was conducted to explore reactions of 21 students to treatment manuals for substance abuse. Students were randomized to experimental (n = 11) and attention-control (n = 10) groups involving exposure to one of two manual-based therapy interventions. Quantitative…

Distance education cannot escape comparisons to traditional classes, and critics of distance education frequently point to the higher drop rate in distance education as evidence of its lower educational quality. While David Diaz and Ryan Cartnal note that this conclusion is a debatable one, they acknowledge that reducing drop rates in online…

There is an increasing interest in linking character education programs with social and academic outcomes. The Child Development Project (CDP) is a character education program that promotes academic and social growth in teachers and students. This theory-driven evaluation employed a quasi-experimental design with matched control schools. School…

In this article, the author examines the added value of strengths-based interventions in response to her college president's challenge that an educator should not be simply out for a talk in teaching. She redesigned her dissertation experiment to measure the impact of strengths-based teaching in two classrooms of Introduction to Public Speaking…

This paper evaluates the effectiveness of a student controlled computer program for high school mathematics based on instruction principles derived from Schoenfeld's theory of problem solving. The computer program allows students to choose problems and to make use of hints during different episodes of solving problems. Crucial episodes are:…

In this study, the effectiveness of learning environments, developed in line with the specifications of the four components instructional design model (4C/ID model) and the additional effect of ICT for fostering the development of technical expertise in traditional Ghanaian classrooms, was assessed. The study had a one-by-one-by-two…

A Monte Carlo study was done to determine the adequate sample size for quasi-experimental regression studies, which compare regression lines for two groups and estimate their point of intersection. Populations of 1,000 subjects in each of two groups were constructed (using random normal deviates) to yield equivalent regression lines of opposite…

Preschoolers in a model preschool designed to develop children's planning and problem-solving abilities were compared to children in three comparison preschools on measures assessing children's ability to solve problems and plan. Children were also compared on other measures of cognitive ability, including measures of general cognitive…

The activities of the Multilevel Analysis Project of the Center for the Study of Evaluation from February 1 to June 1, 1978 are summarized. Twelve project staff activities are listed, including papers on alternative analytical models for identifying educational effects, conference presentations, and grant proposals. A report on empirical…

An approach for merging quantitative-qualitative data in order to enlarge the evaluators' perspective and provide an enriched data base for evaluating elusive evaluation problems in school settings is described. Mini-case studies were conducted over a period of three years in 11 urban schools to examine the impact of an arts-in-the-schools program…

Seven studies commissioned by the U.S. Department of Labor measuring the net market impacts of the Comprehensive Employment and Training Act are reviewed. Their purpose was to generate informed debate on the efficacy of quasi-experimental designs and structural economic models to evaluate federally subsidized employment and training programs. (BS)

Measuring change when true experimental conditions do not exist is a difficult process. This article reviews the artifacts of change measurement in evaluations and quasi-experimental designs, delineates considerations in choosing a model to measure change under nonideal conditions, and suggests ways to organize models to facilitate selection.…

Alternate approaches to traditional research techniques available for the physical educator are: (1) field research, using structured and unstructured observation in actual settings; (2) survey analysis to ascertain current conditions or practice; (3) field experiments conducted in actual settings with experimenter controls; (4) time series…

At-risk adult literacy learners (n=20) were randomly assigned to a control group or one of three treatments: counselor-teacher team support, small-group instruction with students not at risk, or one-on-one tutoring. All in the treatment groups persisted longer than controls. The small group method was most effective for retaining students. (SK)

Interactive Web-based tutorials were developed as a supplement to lectures in an introductory statistics class. A quasi-experimental design compared learning outcomes of students who attended one of two classes that offered the tutorials to students as an extra-credit course option to those who attended a lecture-only class. Analysis of critical…
