Examined whether variations in performance of (n=396) engineering students on a measure of spatial visualization were related to prior spatial experiences and to the developmental period when the prior experiences occurred. One finding revealed nonacademic activities seemed to have the most positive significant relationship to spatial…

In engineering and visual arts, visualization and manipulation of objects is necessary. Describes effective factors on performance which include spatial skills. Describes a project that is designed to increase engineering students' visualization skills. Lists objectives, hardware, and software requirements for the project and considers long term…

Describes a pregraphics course for freshman engineering majors weak in three-dimensional spatial visualization skills. Freshman students scoring less than 60% correct on the Purdue Spatial Visualization Test: Rotations (PSVT:R) were counseled into the course. Gain scores for students after the course on the PSVT:R were shown to be statistically…

Illustrates the use of a course focused on developing 3-D spatial skills at Michigan Technological University. Provides data to support the recommendation that some students take the spatial skills course before enrolling in the regular engineering graphics courses. (DDR)

Investigates the effectiveness of using trimetric pictorials instead of isometric pictorials on the Purdue Spatial Visualization Test - Visualization of Rotations (Guay, 1977). Records student responses and response times as well as information on gender, current major, and number of previous graphics courses completed. (Contains 18 references.)…

Describes the development of a test designed to allow meaningful and widespread computerized testing of various spatial factors. Examines the differences between traditional paper and pencil and computerized versions of the same test. Compares an interactive test designed to measure a working memory factor to the computerized version of…

Compares results of Successive Perception Test I (SPT) for the study population of freshman engineering students to their results on the group-administered Purdue Spatial Visualization Test: Visualization of Rotations (PSVT) and the individually administered Haptic Visual Discrimination Test (HVDT). Concludes that either visual and haptic…

Answers several questions regarding background information on research in spatial skills. Describes strategies that graphics educators can adopt to develop these skills in students. (Author/CCM)

Describes new geometric computer models used in contemporary computer-aided design (CAD) software including wire frame, surface, solid, and parametric models. Reviews their use in engineering design and discusses the impact of these new technologies on the engineering design graphics curriculum. (Author/CCM)

An overview that gives an introduction to the theories, terms, concepts, and prior research conducted on visualization is presented. This information is to be used as a basis for developing spatial research studies that lend support to the theory that the engineering and technical design graphics curriculum is important in the development of…

The results of a nonrandomized experiment indicated that the group of students who observed the static presentations of graphic images achieved slightly higher scores on the paper-and-pencil performance tests, whereas the group of students who viewed the dynamic presentations made greater gains on the mental rotation tests. (JJK)

Reports on a study to determine whether the presence of coordinate axes in a test of spatial-visualization ability affects scores and response times on a mental-rotations task for students enrolled in undergraduate introductory graphic communications classes. Based on Pavios's dual-coding theory. Contains 36 references. (DDR)

A proposition that 3-D CAD provides an array of unambiguous solutions to engineering problems is illustrated. This proposition assumes that engineering problems are conceived in parallel processing mode while they are solved in sequential processing mode. Circle construction analysis, parallel equidistant planes, and solid modeling are discussed.…

An approach to reduce the barrier between two-dimensional computer-aided drafting and three-dimensional constructive solids modeling is graphically illustrated. This process, or some derivative, encompasses a significant portion of the future direction for engineering graphics education. (KR)

Described is a pilot course which includes a designed set of exercises to instruct students in procedures for creating solid models. A detailed description and analysis of students' various approaches used in completing a final design project are included. (KR)
