interventions and b) standing on a set of sustainability-thinkingskills. Data on these two outcomes of interest are gathered through the use of end ofsemester surveys as well as written reflection activities included in student projects.Student survey results are analyzed with descriptive statistics and thematic analysis foropen-ended items. Written reflections are scored with institute-developed rubrics tied toeach system-thinking skill, depending on the nature of a given reflection prompt.Initial results from thematic analysis of open-ended student survey items suggest thatafter experiencing the sustainability intervention, students exhibit an initial understandingof the three key components of sustainability: social, economic, and

researchers observed that improving 3-Dvisualization leads to better performance in engineering graphics and in most other engineeringcoursework resulting in improved retention and graduation rates. The majority of the 3-Dvisualization exercises currently being used by students in Design and Graphics classes presentthe objects in isometric views already in 3-D, asking the viewer to create multiple views, foldpatterns, manipulate, reflect, or rotate them. Other exercises present the objects in incompletemulti-view projections and ask the students to add missing lines. The newly proposed methoduses a different approach. It uses the standard multi-view projections to show a number ofrectangular bricks arranged in various patterns. The viewer must count

No statistically significant changes were observed in thesemeasurements. Instructors of this follow-on course noted that there was some improvement instudent’s ability to produce site maps and drawings, though the improvement was not large.These survey results displayed in Figures 2 through 4 may reflect some of the difficultiesencountered in the first offering of the course including the need for additional student supportsfor the demands of this new course. 25 Before After 20 % of Students 15 10

springs and valves, not to mention water passages and holesfor fasteners.”“This project was my real first use of editable parameters in CATIA, which undoubtedly is goingto be useful. I also got a better sense of how to design things in such a way that they won't allbreak the second I change a little detail up in the design tree.”“I had a basic understanding of port flow characteristics, but had no idea about tapering thecross-sectional area towards the valve or how important the shape of the bottom edge of therunner meeting the valve seat was. Also, how the shape is ideally a D sort of shape and howoften car manufacturers throw that out of the window (looking at you, LS cathedral-portheads).”Student comments reflect improvements in student

the Rochester Institute of Technology. Thiscourse is typically taken by students in the 1st year of mechanical engineering and studentspursuing a minor in mechanical engineering. The structure of the course is shown in Figure 1. Thecontent is provided by two Mechanical Engineering faculty, one mechanical engineering staffmember, and a group of undergraduate teaching assistants. The design project for the course is arobotic chime machine. CAD modeling techniques are demonstrated to enable team members tocollaboratively design their chimes early enough to be able to build. Additionally, a full Figure 1- Engineering Design Tools Course Structuredocumentation and drawing package reflects the parts created in the context of the machiningportion of

the underlying factors ofspatial ability such as Spatial Visualization, Spatial Orientation, and Speeded Rotations [12].Other studies have broken down speeded rotations into sub-topics such as Closure Speed,Flexibility of Closure and Perceptual Speed [13]. Tests have been developed to ascertain spatialreasoning skills. Lohman [12] said that the tests that define spatial visualization are complex.Some require rotation, reflection, or folding of complex figures, while others require combiningdifferent figures or multiple transformations. Yilmaz, who conducted a literature review ofspatial reasoning issues, summarized different ways of measuring spatial ability and said thatsome spatial visualization tests have been shown to be more advantageous

" resourcesStudents and faculty have developed multiple alternatives to a true PDM solution. The utilizationof non-PDM solutions is common and should be mentioned to provide an understanding of whatstudents have been doing in the hopes of motivating the adoption of a PDM solution into all oftheir CAD efforts. The subcategories below are ordered to reflect an increasing amount offeatures that are found in PDM software. The last category includes several industry-standardPDM solutions that are available to educational institutions. All of the solutions below can beimplemented for free or at a nominal cost per year, depending upon the license agreement thathas been negotiated with a software provider.2.1 Shared DrivesAn important feature of PDM is to provide

are repeatable at other universities.Limitations of the StudyIn this study, the prior exposure of the participants to sketching and CAD modeling packages isnot explored. In the student population in SJSU, it is typical that around 10% of the students inthe design graphics class possess some extent of CAD training. However, this is not expected tosignificantly bias the results. This factor will be explored in future studies.AcknowledgementsPartial support for the work is provided by the National Science Foundation grant number DUE-1611763.
