An examination of articles in the last 5 years of the "American Educational Research Journal" (AERJ) was conducted to determine the extent to which choices of levels of parameters in a multivariate analysis were comparable to empirical research that uses multivariate analysis of variance (MANOVA). Originally, a main question was to…

A non-linear version of redundancy analysis is introduced. The technique is called REDUNDALS. It is implemented within the computer program for canonical correlation analysis called CANALS. The REDUNDALS algorithm is of an alternating least square (ALS) type. The technique is defined as minimization of a squared distance between criterion…

Two iterative procedures for constructing Rasch scales are presented. A log-likelihood ratio test based on a quasi-loglinear formulation of the Rasch model is given by which one item at a time can be deleted from or added to an initial item set. In the so-called "top-down" algorithm, items are stepwise deleted from a relatively large…

Program impact methodology--usually referred to as evaluation research--is described as it is developing in the United States. Several problems face the field of evaluation research. First, those issues grouped as "meta-scientific" include: (1) the distinction between qualitative and quantitative studies; (2) the separation of implementation and…

Instructional applications of Q methodology (a set of procedures that can be used in studying the subjective nature of things) provide a means for teaching communication skills, analyzing thinking patterns, making comparative analyses, and structuring intrapersonal processes. Taking the best from quantitative and qualitative research methods,…

This report examines the process of job evaluation as a method of measuring job worth. Latent trait theory is applied to suggest methods of identifying wage bias. The point factor method of job evaluation selects compensable factors and weights them, using regression analysis. This method is used to maximize the prediction of the existing wage…

Admissions practices at the North Carolina School of Science and Mathematics, a residential high school for gifted students, were examined. Data from students applying in 1983 and 1984 (over 800 per year) were available, as were grades of students admitted in 1983. A series of multiple regression studies showed that selection and first year grades…

To simplify data from a large survey, it is desirable to classify subjects according to their attitudes toward certain issues, as measured by questions in the survey. Responses to 12 questions were identified as indicative of attitudes toward deschooling education. These attitudes were explained by means of patterns exhibited within the responses…

Long term studies of advance organizers (AO) were analyzed with Glass's meta-analysis technique. AO's were defined as bridges from reader's previous knowledge to what is to be learned. The results were compared with predictions from Ausubel's model of assimilative learning. The results of the study indicated that advance organizers were associated…

These symposium papers discuss the instructional use of computers in psychology, with emphasis on computer-produced simulations. The first, by Rich Edwards, briefly outlines LABSIM, a general purpose system of FORTRAN programs which simulate data collection in more than a dozen experimental models in psychology and are designed to train students…

This overview of both quantitative and qualitative methods of educational forecasting is introduced by a discussion of a general typology of forecasting methods. In each of the following sections, discussion follows the same general format: a number of basic approaches are identified (e.g. extrapolation, correlation, systems modelling), and each…

Problems associated with the analysis of data collected using the Solomon Four Group Design are discussed. The design includes an experimental group and a control group that have been pretested and posttested, and an experimental and a control group that have been posttested only. A sample problem is approached in three different ways. First, the…

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…

The National Assessment of Educational Progress (NAEP), like most large national surveys, employs a complex stratified multistage unequal probability sample. The design provides a rigorous justification for extending survey results to the entire U.S. target population. Developments in the analysis of data from complex surveys which provide a…

The possibilities and problems in the use of within-group slopes of outcomes on inputs as indicators of substantive educational group effects are considered. Slopes are proposed as outcome measures which may reflect within-group processes in between-group analyses of multilevel data. Research on aptitude x treatment interactions, contextual…
