Computer-Aided Design (CAD) technologies are an essential part of modern design endeavors. In today's industry, engineers use CAD models throughout their work. This makes CAD education crucial. However current CAD education has typically focused on narrow skills related to particular CAD software. The skills necessary to adapt new CAD software and effectively utilize the existing models in modified designs are not the primary emphasis in CAD education. In this paper, the most recent findings of a three-year NSF supported iterative project are discussed. The project goals are to examine the role of adaptive expertise in CAD modeling and investigate the impact of a learner-centered contextual exercise on students' modeling behavior and other educational outcomes. This paper builds on previously reported work. Findings that combine: participating students' responses to an Adaptive Expertise Survey (AES), coded interviews with students and practicing engineers, and the participants' demographic information are reported. Research activity participants include students from Texas A&M University (TAMU) and Prairie View A&M University (PVAMU). At each campus, a control group and an experimental group were formed to complete modeling exercises. Students in the experimental group completed a contextual exercise and created CAD models based on some objects that the students were familiar with and frequently used in their daily lives. Students in the control group were asked to model an object that was similar to a textbook exercise. A summary of the data collected and the statistical relationships among the study variables are presented. The study's context and implications for CAD education are discussed. © American Society for Engineering Education, 2013.

A methodology for examining the role of adaptive expertise on CAD modeling
Johnson, Michael D.; Öztürk, Elif; Valverde, Lauralee; Yalvac, Bugrahan; McGary, Prentiss; Peng, Xiaobo (2013-01-01)
Computer-aided design (CAD) tools play a significant role in the modern product commercialization environment. As CAD and general CAx technology advances, it becomes more important to understand how engineers adapt their expertise to new environments and problems. This work examines a methodology consisting of a set of surveys, interviews, and exercises with a small group of practicing engineers to assess adaptive expertise (AE) and relate this AE to CAD modeling performance and procedures. Results detail A...
Examining adaptive expertise: A novel comparison of student and practicing engineer cad modeling performance
Johnson, Michael D.; Öztürk, Elif; Yalvac, Bugrahan; Valverde, Lauralee; Peng, Xiaobo; Liu, Ke (2015-01-01)
Computer-aided design (CAD) tools are critical in the current fast-paced digital product commercialization environment. As firms move towards a model based enterprise, it becomes more important for engineers to develop the skills necessary to efficiently and effectively model components in CAD. The status of CAD education and training has often been decried as focusing too much on declarative knowledge, namely how to do specific procedures in a specific software program. This is opposed to the strategic kno...
Evaluation of basic design education at METU department of industrial design
Bayırlı, Ümit; Özgen Koçyıldırım, Dalsu; Department of Industrial Design (2015)
Basic Design is a crucial course for design education. This course is offered in the first year to initiate students to the theory, practice and communication of design and to lay a basis on which more advanced and specialized knowledge will be gathered throughout the rest of their design education and careers. However, the course's results, influence in design education and methods of conduct receives many criticisms from students, educators, designers and researchers. Even though the course plays a foundi...
Analyzing Adaptive Expertise and Contextual Exercise in Computer-Aided Design
Peng, Xiaobo; McGary, Prentiss; Öztürk, Elif; Yalvac, Bugrahan; Johnson, Michael; Valverde, Lauralee M. (2014-01-01)
The fast changing pace of modern CAD tools has demanded the users to be more adaptive to apply their CAD skills. This paper presents the initial work to transform adaptive expertise in the CAD education. An adaptive expertise survey (AES) and a contextual exercise were implemented in a freshman CAD class. The students' responses to the survey and interviews were analyzed. The CAD models were evaluated based on the attributes. The statistically significant relationships among the variables are reported. The ...
Sayısal Ortamda, Tasarımın Deneyimlenmesi İçin Arayüzlerin Geliştirilmesi: Bir Ön-Tasarım Parametresi Olarak Ses
Özgenel, Çağlar Fırat; Sorguç, Arzu (2011-01-01)
In architecture of our day, with the enhancement in technology, experiencing design decisions and / or changes by means of various computational technologies in computational medium has become an essential design tool. With the presence of the tools used in computational medium, changes in the architectural design process occurred and the usage of the tools drifted from simply virtual experience to optimization of the design by examining the design throughout the process. In the performance based design app...
