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.

Described is a computer algorithm for obtaining the coordinates of vertices, chord factors, and dihedral angles for plotting orthographic and axonometric projections, and for tabulating chord lengths and dihedral angles. (Author)

Indicates that increased exposure to different objects in teaching orthographic projection benefits students, especially when they can manipulate and see the surfaces, points, and lines simultaneously or sequentially in three views. Positive attitudes and increased scores were noted after students used interactive computer graphics in an…

Presents the results of statistical analyses and interpretations of data obtained from students in two engineering fundamentals courses on an attitudinal survey. Indicates positive and significant improvement in student attitudes toward their own drawing abilities and the importance of drawing in their lives and careers. (CW)

The results of an experiment in teaching engineering graphics using the traditional lecture-homework-laboratory technique are compared to a newer lecture homework proposal. Although the newer method reduces professor-student contact, it may prove to be as effective as the older method requiring laboratory instruction. (KR)

Students' reactions and performances were examined when taught engineering geometry concepts using a standard microcomputer-aided drafting software package. Two sample groups were compared based on their computer experience. Included are the methodology, data analysis, and conclusions. (KR)

Developed is an examination to determine a student's visualization capabilities. This examination has two versions, both developed to measure visualization ability, time to visualize, and reaction time. This test indicates the learner's ability to visualize complex three-dimensional objects from six principal views. Included are the results from a…
