An analysis was conducted of feature articles published in the EDGJ (Engineering Design Graphics Journal) and indexed later by ERIC (Educational Resources Information Center).  After a spreadsheet was promulgated with data extracted from the ERIC database and validated with the…

Kolb (2004) and others have defined learning style as a preference by which students learn and remember what they have learned. This presentation will include a summary of learning style research published in the Engineering Design Graphics Journal over the…

The paper presents a unique approach in associating perspective projection with the image beheld by the eye and demonstrates that all graphical and photographic perspective projections must contain distortion when compared to the image beheld by the eye.

This phenomenological investigation examined the lived experience of technically-oriented students over the course of a single semester, attempting to answer the question, “What was it like for a student to experience the spatial ability phenomenon?” The study included 12 interviewees…

With current computer-aided design technology, the traditional tasks of a designer, drafter, analyst, and prototype maker are all performed by a single engineer using modern digital engineering design tools.  These digital tools include computer systems with 3-D solid modeling software,…

Fundamental construction in descriptive geometry deal with determining the intersection of various elementary solids, such as planes, cylinders, and cones.  Systems involving planes, cylinders, and cones are generally produced from sheet metal or other thin materials.  When panels of these…

The objective of this paper is to present applications of solid modeling aimed at modeling of complex geometries such as splines and blended surfaces in advanced CAD courses. These projects, in CAD-based Mechanical Engineering courses, are focused on the use…

There has been a significant history of research on spatial ability and visualization improvement and related curriculum content presented by members of the Engineering Design Graphics Division over the past decade. Recently, interest in this topic has again been heightened…

This paper discusses the character and challenges inherent in the graphical portrayal of features in subsurface mapping.  Subsurface structures are, by their nature, hidden and must be mapped based on drilling and/or geophysical data. Efficient use of graphical techniques is…

By supplying various combinations of advanced instructions and different forms of exercises individual learning processes within the impartation of basic knowledge can be activated and supported at best. The fundamentals of our class “Introduction to spatial–geometric cognition using CAD” are…
