The purpose of this study was to determine the effect of practice in manipulating 2- and 3-dimensional (D) wireframe images on a learner's ability to visualize 3-D objects. Practice, either rotational or not, consisted of visualizing 2- and 3-D objects generated by personal computer (PC)-based computer-assisted design software. Results indicated that(More)
In less than two decades the electronic digital computer has evolved from a high-speed replacement for the abacus to a full-fledged partner in dialogue with humans. By its very nature, on-line computing thrusts the user into an entirely different environment than does conventional batch processing. The problems inherent in a person's being made a system(More)
In virtually every part of American life, the development of usable skills and knowledge is essential. Documentation of performance is needed in order to demonstrate competency in school, to acquire and maintain employment, for career advances, and especially in areas where the cost of failure is unacceptable, such as in medicine, protective services, and(More)
The hypothesis that memory support (MS) reduces state anxiety (A-State) and errors in a computer assisted learning task was investigated. It was predicted that high A-State students given MS would make fewer errors than high A-State students given no memory support (NMS). Low A-State students were expected to perform equally as well with or without MS.(More)
