The reason for conducting the present case study was the problems the researchers encountered during data collection for another research project (Primary Study) entitled "The effects of virtual versus traditional flipped classes on EFL learners' grammar knowledge, self-regulation, and autonomy." Two online questionnaires were…

The commentaries on my article contain a number of points with which I disagree but also several with which I agree. For example, I continue to believe that the existence of many cases in which between-person variability does not increase with age indicates that greater variance with increased age is not inevitable among healthy individuals up to…

The thesis of this paper is that, in evaluating most innovative educational projects that are conducted in schools, tenets of formal experimental design and associated inferential data analysis methods should be given limited emphasis. The basis of this thesis lies in the problems and difficulties that undermine the design and implementation of…

Many evaluation researchers are now attempting to synthesize quantitative and qualitative approaches. Although such efforts appear to carry great promise, some subtleties and incompatibilities of these approaches are perhaps being overlooked. Implications for social inquiry are discussed.

The rationale for a multistage approach to evaluating services demonstration programs is discussed. The approach takes into account limitations that are often found in such programs. The National Evaluation of Models for Linking Drug Abuse Treatment and Primary Care provides an example. (SLD)

This paper acknowledges that research on school dropouts presents problems in the definitions and computation of dropout indices. It considers a variety of methods for computing dropout rates, using dropout rates which are real and which were available at the end of the 1986-1987 school year. Fall enrollment, average daily membership, and total…

Global economic transformations have never been as dramatic as in the twentieth century. Most countries have experienced radical changes in the standards of income per capita, technology, fertility, mortality, income inequality and the extent of democracy in the course of the past century. It is the goal of many disciplines--economics, history,…

This briefing report on program evaluation notes that the new wave of family-centered, integrated services is forcing the field to rethink its methodology, and that the move towards outcome-driven reforms requires carefully defined outcomes and ways to measure them. Highlights of a seminar meeting held to explore these issues are included. The…

A between method triangulation strategy was used to evaluate a process for long-range program planning. One study team conducted interviews and the other used a mail questionnaire. The resulting problems in coordination between teams are discussed. (Author/GDC)

Two innovative methods for collecting and analyzing qualitative data are vignettes and pre-structured cases. Vignettes are descriptions of situations or problems written by a professional, with a suggested outline and comments provided by a researcher. Advantages of this method are strength of impact of the written descriptions and efficiency of…

This report summarizes results from research aimed at improving the quality of information collected about school curriculum. The research sought to design and pilot a model for collecting benchmark data on school coursework. These more indepth data, such as course textbooks, assignments, exams, and teacher logs, can serve as anchors against which…

Modeling and data collection efforts needed to develop a test of the effectiveness of adult literacy and language training programs in increasing the earnings of trainees are reviewed. After reviewing the framework developed for the Manpower Development and Training Act and the Comprehensive Employment and Training Act (CETA) evaluations and the…
