A growingbody of literature is available, addressing and discussing the definition and use of variouscompetences including systems-thinking and critical thinking for sustainabledevelopment [2,3] . Systems-thinking is identified as an important learning outcomerelated to incorporating sustainability in engineering classroom. Additionally, systems-thinking provides an understanding of a system by examining the link and interactionsbetween the elements that comprise the whole system. Sustainability systems-thinkingskills include (i) identifying dynamic relationships

Accordingly, the Lego™ assembly test is proposed as a suitable way toassess spatial visualization ability for elementary school age students.IntroductionIn recent years, it has increasingly been recognized that spatial visualization skills are importantin supporting student success in Science, Technology, Engineering, and Math (STEM) educationand retention of these students in STEM careers ([1]-[5]). Many first-year college engineeringprograms and high schools with pre-engineering curriculum have incorporated spatialvisualization training into their curriculum and have seen large learning gains in spatialvisualization skills ([6]-[11]).Several researchers have attempted to provide a clear definition of

For each project, students in bothgroups submitted their first draft for peer assessment (either through paper-based critique orACJ), and were allowed one week before the final submission to improve their design based onthe feedback they got from the in-class peer critique process. The paper group, who used a traditional paper-based peer critique method, printed outtheir draft and brought one copy to class. These students were then assigned into groups of fiveto six and each was given a peer critique worksheet (See Figure 1) and copies of design draftsfrom another group. To

object geometries, whereas strategic knowledge involves higher-order designdecision making [1]. For Chester, strategic knowledge is critical because it is the primarydeterminant of both the efficiency with which a design is completed and the extent to which adesign captures “design intent,” or the ability of the resulting artifact to achieve requirements asit is iterated over time. In this essay, we argue that learning CAD software also involves“epistemic” dimensions of knowledge—knowledge not about discrete facts and processes, butabout the interrelations of CAD and design more broadly, or how the design tool shapes thedesign process and its outcomes. Epistemic knowledge, then, is less about “what” CADpractitioners know, but rather “how” they

In this paper, the program was used to examine theincidence of these types of plagiarism by retrospectively examining more than 3000 CAD filesover fourteen semesters during a seven-year period. We have found plagiarism in this CADcourse to be a relatively uncommon occurrence, but nevertheless present in 1-2% of allsubmitted files, and involving as many as 16% of all students in a particular section.

engineering,spatial visualization ability is essential to many applications, beginning with engineeringgraphics. Engineering graphics courses are commonly introductory-level classes in engineeringprograms, creating challenges for women, who on average score lower on tests of spatialvisualization ability. Improved understanding of gender differences in engineering graphicsclasses could therefore help identify pedagogical areas to support women and increase theirretention in engineering programs. Although a gender gap exists in spatial ability andperformance in engineering graphics classes, female students still achieve positive courseoutcomes. We hypothesize that: 1) female students put more effort into engineering graphicscourses; and 2) that this

.    Introduction  Spatial reasoning is an important predictor of student success in STEM fields [1], [2]. Sorby  reports that spatial cognition has been a focus of research for nearly a century. One important  part of spatial cognition is "spatial visualization, which is defined as the process of  'apprehending, encoding, and mentally manipulating three dimensional spatial forms'" [3].  Given this importance of spatial visualization, an important question is if and how students'  spatial visualization skills can be developed. Sorby studied the effect of students taking a 1-credit  spatial skills course, and found multiple benefits: improved performance in introductory

For engineers, the graphics language using lines and symbols to representinformation has been proved to be more effective than verbal communication [3].
