An analysis of the historical roots of educational technology is followed by discussions of concerns for instructional design and media selection, systematic approaches to instruction, and the future uses of technology for the delivery of instruction and information. The development and growth of the field are explored, future applications of…

The objective of this document is to make recent master's theses known to professionals and students who may profit from the work of colleagues. The compilation is also intended to serve as an indication of the current nature of graduate education in the field. Included in the compilation are sections covering site analysis; park users and…

The testing of contemporary sociological theory often calls for the application of structural-equation models to data which are inherently collinear. It is shown that simple ridge regression, which is commonly used for controlling the instability of ordinary least squares regression estimates in ill-conditioned data sets, is not a legitimate…

INVESTIGATED WAS THE EXTENT TO WHICH STUDENTS COMPLETING PLANNED MATHEMATICS EDUCATION PROGRAMS (1) WERE PROFICIENT IN SPATIAL VISUALIZATION ABILITIES, AND (2) HAD DEVELOPED MATHEMATICAL UNDERSTANDINGS. THE EFFECTS OF THE MATHEMATICS CURRICULA UPON SUCH DEVELOPMENT WERE INVESTIGATED BY COMPARING GROUP MEAN TEST SCORES OF PROSPECTIVE ELEMENTARY AND…

This study was conducted to (1) identify certain concepts of relativity, and (2) determine the relationship between understanding of these relationships achieved by pupils in grades 4-8 (as indicated by objective test scores) and such variables as grade level and mental ability. Several related sub-problems were also identified. A conceptual…

In a 1964 investigation of the effects of age and memory on problem solving, using subjects from age three to age nineteen, it was found that the youngest and oldest subjects performed a three-choice probabilistic task significantly different from the "middle-age" children (7 to 9 years old). The three-choice task was an apparatus with a…

Although it is widely accepted that early childhood is the optimal, time to begin educational intervention, there does not seem to be an agreement on the specific kinds of interventions. For the disadvantaged child, however, it seems that intervention in infancy and very early childhood is especially indicated. This summary and literature review…

The relative effectiveness of two methods of instruction for teaching 5th and 6th grade students to separate variables in science activities isinvest gated. Randomly selected students from a particular school were test d until 27 who were unable to separate variables had been identified. These students were randomly assigned to three groups.…

Studied were the relationships between children's attainment of the concept of conservation of liquid and certain student characteristics. Student factors investigated were socio-economic background (high and low), status levels (conservers and non-conservers), verbal and non-verbal achievement, and science achievement. Classification of subjects…

In studies of what teaching styles are effective for particular types of students, it was found that (1) students having a great need for affiliation performed better in classes taught by friendly teachers, while students needing little affiliation performed better in classes taught by more impersonal teachers. (2) A student's need for achievement…

This study involved examining an instructional unit with regard to its concept content and appropriateness for its target audience. The study attempted to determine (1) what concepts are treated explicitly or implicitly, (2) whether there is a hierarchical conceptual structure within the unit, (3) what level of sophistication is required to…

This document is a report on the Conference on Needed Research in Mathematics Education held on the campus of the University of Georgia. A major objective of the conference was an examination of the progress of research in mathematics education as well as the development of guidelines for further research. Toward this end, the Conference was…

The focus of this paper is on the complex interaction between teacher behavior and learner outcomes and the search for associational and causal relationships between them. Both the results from research conducted in this area and the methodology used to conduct the studies are examined. Answers to the following questions are reported. What links…

Statements of learning objectives are provided to substantiate the goal of economic understanding in Wisconsin schools and to provide a quick inquiry device that educators and others may use to more clearly establish whether or not opportunity for economic education exists sufficiently in the school curriculum. These statements, or…

The LORS technique is a combination of several techniques such as role projection, simulation, psychodrama, feedback, value clarification, role reversal, dramatization, decision making, process analysis, and others. The significant difference is that, when the techniques are used together, each often undergoes changes to the point that the effect…
