This paper examines the multivariate multiple regression model and explores its applicability to communication research. The first section discusses partitioning of a data matrix, as a heuristic device for distinguishing among alternative regression models. Section two examines various aspects of univariate multiple regression, including the form…

The pretest-posttest design referred to as Design 2 by Campbell and Stanley (1963) is commonly used in educational research and evaluation. The tenability of the assumption of a zero population difference commonly used with this design is questioned. A nonzero population estimate based on the mean difference observed in test-retest reliability…

Using computer controlled text presentation that permitted the measurement of reading time for individual sentences, a study tested two hypotheses concerning how schemata guide reading comprehension. The focusing hypothesis suggested that the schemata activated by the reader's perspective might identify relevant information to which additional…

Student team techniques, involving two conceptually distinct components--a cooperative reward structure, in which students are evaluated and rewarded based on the performance of the group as a whole, and a cooperative task structure, in which students are encouraged to peer tutor--have had positive effects compared to control methods on academic…

GREATER UNDERSTANDING OF INFERENTIAL STATISTICAL METHODS AND EXPERIMENTAL DESIGN WOULD ENABLE LANGUAGE TEACHERS TO INTERPRET OBJECTIVELY AVAILABLE RESEARCH REPORTS AND HOPEFULLY WOULD ENCOURAGE MORE EXPERIMENTATION. TO UNDERSTAND THE EXPERIMENTAL PROCESS, EDUCATORS MUST REALIZE THAT ANY EXPERIMENT IS AS SUCCESSFUL AS THE EXPERIMENTER IS IN…

PUBLISHED CHILDREN'S VOCABULARY LISTS BASED ON ACTUAL USAGE ARE ALL DRAWN FROM RESEARCH DONE PRIOR TO 1930. THE PRESENT STUDY REPLICATED THE 1926 BUCKINGHAM-DOLCH STUDY TO DETERMINE ANY VOCABULARY CHANGES. THE 2 HYPOTHESES TESTED WERE (1) THERE IS NO SIGNIFICANT VOCABULARY SHIFT, AND (2) COMMON WORDS DID NOT DIFFER IN GRADE-PLACEMENT (THE EARLIEST…

THE RESEARCH REPORTED IN THIS WORKING PAPER "STRONGLY INDICATES" THAT SEMANTIC UNIVERSALS HAVE BEEN DISCOVERED IN THE DOMAIN OF COLOR VOCABULARY. MOREOVER, THESE UNIVERSALS APPEAR TO BE RELATED TO THE HISTORICAL DEVELOPMENT OF ALL LANGUAGES IN A WAY THAT CAN PROPERLY BE TERMED EVOLUTIONARY. THE RESEARCH WAS CONDUCTED IN A GRADUATE…

The three papers presented in this publication examine in depth the thought and practices that currently prevail in the specialized areas of reading and concept attainment. Two of the papers deal with concept learning and the transformation of this knowledge into instructional guidelines. The third paper considers the importance o f concept…

The paper presents a speculative model of the growth and development of an occupational education program as it responds to changes in student interests and job market conditions. Informal discussions with the directors of several occupational schools in Massachusetts provided the base for the model. Intended as a tool for educational managers, to…

The degree to which the chosen units of analysis are likely to produce spurious findings in staged combinations of multiple linear regression procedures are examined. The effects of grouping variables (e.g., classroom, school, and school district) on Procedures such as Coleman's semipartial regression and Mayeske's commonalities, in light of…

A proposal to formulate nomothetic theories -- general statements or scientific laws -- in a way to allow for an immediate test of individual differences is presented. The need for such a proposal is cited in recent developments in structural model building in the area of memory called information processing and in the concern to bring individual…

This report critiques Herschel Kasper's study on the impact of collective bargaining on public school teachers, a report that found little relation between unionization and average State salary levels. This paper makes three major objections to Kasper's study: (1) its use of State data as the basis for observations in the cross-sectional analysis…

In order to determine whether the kind of process underlying cloze responses is indeed a systematic and exhaustive search, a study was conducted exploring some corollaries to such a search hypothesis. It was assumed that subjects would generate responses representing a number of word types, that some of these word types would be sensible and some…

The purpose of this study was to assess the importance of teacher attitudes, maternal attitudes, and traditional versus Montessori nursery school training on the learning and achievement of the preschool child. Eighty-two middle class children and thirty-eight disadvantaged children who attended either Montessori or traditional preschools…

Studied was the effect of art education on productive changes in perceptual, cognitive, and attitudinal styles, and on the art aptitudes of disadvantaged youth. The study examined the assumption implicit in many school programs that art education is somehow beneficial to poor and minority group students. The research design divided teachers of…
