One purpose of this research is to develop models of cognitive processes in understanding mechanical systems. A particular focus was on the processes in mentally animating the representation of a mechanical system, and the contribution of animation graphics in comprehension. Several studies, involving eye fixations, verbal protocols, and process…

This dissertation presents the results of an investigation of visual mental imagery as a strategy hypothesized to increase the amount of interaction with content material and therefore the level of information processing and acquisition, and to assist information retrieval on posttests. Four treatments were used in a crossed, randomized two by two…

Three-dimensional (3-D) aerial photographs viewed with cardboard filter glasses (anaglyphs) aid elementary and junior high school students in recognizing physical features, offer a realistic vertical perspective, and have motivational values. A review of research on cognition, perception, and the use of anaglyphs reveals that pictures are an…

Meta-analysis techniques were used to summarize the results concerning gender differences reported in doctoral dissertations on visual spatial skills. Dissertations were chosen because they are not subject to the selection process of journals, which may bias results toward large effects. An analysis of 150 independent data points in 43…

This paper considers the feasibility of incorporating research results from cognitive science into the modeling of performance on psychometric tests and the construction of test items. The paper focuses on the feasibility of modeling performance on a three-dimensional rotation task within the context of Item Response Theory (IRT). To test the…

The ability to "image," or to conjure up verbal and nonverbal pictures, is fundamental to language arts activities. This paper lists eight imaging skills, which involve attention to details, sizes, multiple images, viewpoint, lighting, perspective, emotions, and structure, and suggests that each of these skills may be taught in conjunction with…

This report is part of a general study of Reference Measures for Cognitive and Noncognitive Factors. The main activity being reported is the development of "factor-referenced" or "marker" tests for several recently identified cognitive factors. A secondary activity involves the study of possible relationships to factors already…

An integrated learning strategy program emphasizing a connection technique employing questions and answers was developed and tested. Components were derived from a review of educational and psychological literature and from an analysis of responses to a learning-strategy inventory. Visual imagery and paraphrasing connection also were evaluated.…

A skilled cognitive theorist might help behaviorists resolve inconsistencies found from their experimentation with imaginal mnemonics in paired-associate and serial learning tasks. Iconic cognition which relegates verbal processes to short-term storage and output systems is inadequate to explain the verbal coding and elaboration processes…

Visuals, like pictures, charts, diagrams, graphics, and the like, are widely used in education. However, there is little justification in the research literature for their use. The overall purpose of this exploratory study was to find out more about the processing of visuals or graphics in an educational task. Specifically, it was thought that…

Sample materials from a primary training packet are included. The packets were developed as a part of a teacher development program aimed at improving elementary mathematics by giving teachers practical ideas. The sample student materials are drawn from the areas of geometry and oral mathematics. (PK)

Using 146 high school students, this research assessed the effects of aptitude, strategy training, and item characteristics on the strategic processes employed in the performance of spatial visualization tasks. Treatment effects were shown to depend on the subject's aptitude profile and on the characteristics of items. (BS)

To investigate the effectiveness of integrating abstract and realistic visualization, the effectiveness of four treatments was measured for: (1) facilitating student achievement of different kinds of educational objectives; (2) students possessing different levels of student ability; (3) externally paced and self-paced methods of instruction; and…

Replicated a study to determine if a sex difference in spatial visualization ability exists among grade six students verging on adolescence and if instruction differentially affects boys/girls at this age. Although instruction significantly affected boys/girls in grades seven to eight, current results do not support the same interaction among…

Argues that college teachers need special skills and sensitivities to be competent at distance education, including: skills in course planning/organization, verbal/nonverbal presentation skills, collaborative skills, questioning strategies, subject matter expertise, skill at involving students and coordinating field site activities, understanding…
