Spatial ability, which affects retention and achievement in engineering and science disciplines, has been shown to improve through training and simply from enrollment in a Computer‐Aided Design (CAD) course. However, detailed analyses of the specific object geometries and rotation types that cause difficulty for students on standardized spatial ability tests or which ones improve based on training has not been performed. This information may assist in determining the optimal training methods to improve the spatial ability skills of students and thus provide the most significant benefits for the training time committed. In this paper, scores from a standardized spatial ability test, which was administered before and after training and/or enrollment in a CAD course, are compared. The results show that the targeted training produced a significant improvement in the spatial ability test scores of students and that these improvements occur across all object geometries and rotation types.  相似文献

Studies concerning student preferences and student learning as a function of the instructional design and delivery of a computer‐based teaching (CBT) module are presented. The studies were conducted in conjunction with the development of twenty‐one CBT modules for an Introduction to Manufacturing Processes laboratory that emphasized metal removal. Study results indicate there is no statistically relevant difference in learning between students using material presented with traditional multimedia (35 mm slides and cassette tapes) and the identical material presented with digital multimedia. Engineering students' preferences for interface design and audio‐visual information presentation are also presented. The most important result is that learning outcomes of a reader‐driven CBT module were found to be statistically lower than those associated with author‐driven CBT module, especially for average and below‐average students. These results suggest that if students must absolutely understand material, e.g., laboratory safety, the CBT should be author‐driven. Based on these results, we speculate that average and below average engineering students are more linear learners. A hybrid scheme, where information presentation transitions from an author‐driven to a reader‐driven environment may help weaker students develop better non‐linear, open‐ended problem solving skills.  相似文献

“工欲善其事,必先利其器”。工具是人类社会和人类文明的产物,是人类智慧的结晶,代表着不同历史时期生产力的发展水平。在漫长的历史长河中,人类的创作意识与劳动创造是相互促进的,在有意识的基础上进行设计,形成经验,再由积累的经验进行选择与改进,形成更丰富的设计观念过程。对中国传统工具设计观念问题进行历史梳理与理论反思,尝试转换研究思路,突破工具设计研究的传统模式,聚焦“工具”“设计观念”“需求”“知识更迭”等要素,进而在设计史学视野之下,将历史纵向梳理与单元专项研究相互结合,互为印证,探索更加合理的传统工具设计观念史的研究范式。  相似文献

Engineering design encompasses professional competencies that complement a solid understanding of engineering science fundamentals, theories, and methods. Engineering schools are increasing their efforts to integrate design into the curriculum, and this paper critically analyses one initiative at a research‐intensive Canadian university, where a three‐course sequence (Design Trilogy) forms the design education backbone in the undergraduate Biosystems Engineering program. Data collection consisted of focus groups with students and one‐on‐one interviews with instructors and industry cooperators. The findings yielded authentic understandings of teaching and learning engineering design, many areas of common perceptions between participant groups, congruence with design concepts in the literature, and areas where students' perceptions and experiences did not correspond to instructors' intentions. Teaching implications include the importance of instructors' transparency and integration in teaching and the need to explicitly prepare students for a different kind of learning experience in the Design Trilogy.  相似文献

Industry often requires engineers to work in teams. Therefore, many university engineering courses require students to work in groups to complete a design project. Due to the increasingly global nature of engineering, opportunities for students to navigate the issues of distance, time, culture, language, and multiple perspectives associated with virtual teams are becoming particularly desirable. To understand students' experience with virtual teams in a graduate course on principles of lean manufacturing, a group of researchers at a midwestern university compared the project performance, selected group processes, and satisfaction of students randomly assigned to face‐to‐face and computer‐mediated communication design teams. Students in both the face‐to‐face and computer‐mediated communication design teams performed equally well on the final project, and reported similar patterns in group processes with a few exceptions. Students in face‐to‐face design teams were more satisfied with the group experience than those in the computer‐mediated communication design teams; however, all reported an overall positive experience.  相似文献

Today's military operating environments are more operationally diverse and technically challenging. Fielding relevant weapons systems to meet the demands of this environment is increasingly difficult, prompting policy shifts that mandate a focus on systems capable of combating a wide threat range. The capabilities‐based test and evaluation construct is the Department of the Navy's effort to concentrate on integrated system design with the objective of satisfying a particular operational response (capability) under a robust range of operating conditions. One aspect of capabilities‐based test and evaluation is the increased employment of advanced mathematical and statistical techniques in the test and evaluation (T&E) process. This case study illustrates advantages of incorporating these invaluable techniques, like design of experiments and modeling and simulation, within the T&E process. We found through statistical analysis that the application of design of experiment concepts to the System Under Test throughout three primary phases of T&E quantifiably improved the accomplishment of the selected response variable of interest.
