This paper reports an investigation that was done ex post facto, examining the hypothesis that within economics courses defined economics students achieved better results than did law students in the same courses. This should not be the case if the courses are truly multifunctional. Information on an economics and money course and a course on the…

This brief paper summarizes a roundtable discussion on the relative lack of use by special education researchers of a variety of qualitative and quantitative methodologies. Discussion addressed: (1) the types of knowledge that could be generated by using a wider range of research methods (e.g., structural equation modeling and associated methods…

This book is intended for a one-semester or one-term course in educational research. It is designed to enable students to become intelligent consumers of educational research and to introduce its basic principles to those who eventually may be involved in research in their work. The chapters are: (1) "Introduction to Research in Education"; (2)…

A detailed investigation of the statistical procedure of W. Stout (the computer program DIMTEST) for testing the hypothesis that an essentially unidimensional latent trait model fits observed binary response data from a psychological test is presented. One finding is that DIMTEST may fail to perform as desired in the presence of guessing when…

This study was conducted to investigate the effects of the animation of visual information when used in conjunction with text and static visuals in microcomputer-based instruction. Of particular interest were consequent performance on higher level learning tasks as a result of viewing these forms of visual presentation, and those levels of…

Science teachers tend to focus on schemas rather than underlying structures with greater explanatory power. One such structure is the recognition that the logical statement implication can only be falsified. After instruction with a modified version of the four-card hypothesis testing task, a grup of 48 preservice elementary teachers were…

This study examines the relationship between the perceptions of undergraduate black students of their adjustment to a predominantly white university and levels of academic success. It is hypothesized that there would be no significant relationship between adjustment to college as measured by the Student Adaptation to College Questionnaire (SACQ)…

Several definitions of career exploration are discussed in the article, and an interpretation is offered for the middle/junior high school level: student exploratory behaviors in regard to self and occupational concepts are best denoted by their inclusion of problem-solving or hypothesis testing.

Introduction: This paper examines the business external environment scanning theory for information in the context of Greece. Method. A questionnaire was developed to explore the relationships between general and task business environment, perceived uncertainty, scanning strategy, and sources of information with respect to type of environment,…

The effectiveness of learning paired associates from a computer-based drill strategy known as the progressive state drill was compared in this study with the effectiveness of having students use their own strategies with flashcards. Characteristics of the progressive state drill which make it a potentially effective drill and practice strategy for…

The hypothesis for this study assumed that subjects who received a diagram representing the structural relationships of a story would be more likely to solve a new and analogous problem than subjects who received two analogs without a diagram. The 151 graduate students who acted as subjects were randomly assigned to one of four treatments: one or…

This study investigated learners' preconceptions of interactive video (IV), instructional television (ITV), and television (TV), and compared three treatment groups on learners' perceptions of invested mental effort and achievement on a test of recall and inference. The three treatments consisted of an IV lesson that included practice questions…

The roles of training, problem representation, and individual differences on performance of both automated (simple) and controlled (complex) process tasks were studied. The following hypotheses were tested: (1) training and cognitive style affect the representation developed; (2) training and cognitive style affect the development and performance…

Two hypotheses, the cognitive capacity hypothesis and the selective attention hypothesis, try to account for the facilitation effects of prior knowledge activation. They appear to be mutually exclusive since they predict different recall patterns as a result of prior knowledge activation. This study was designed to determine whether the two…

This paper discusses distribution theory and power computations for four common "tests of combined significance." These tests are calculated using one-sided sample probabilities or p values from independent studies (or hypothesis tests), and provide an overall significance level for the series of results. Noncentral asymptotic sampling…
