Optimization, An Important Stage Of Engineering Design, Todd R. Kelley 2010 Purdue University

Optimization, An Important Stage Of Engineering Design, Todd R. Kelley

Publications

The presents information on optimization, an important stage of engineering design. Criteria and design constraints are used in the optimization stage of the engineering design process to allow the designer to locate the optimal solution. Before initiating a prototype work, both analysis and optimization are done in designing a product. Optimization is done to create the best design relative to a set of prioritized criteria or constraints, including maximizing factors such as productivity, strength, reliability, longevity, efficiency and utilization.


Design Assessment: Consumer Reports Style, Todd R. Kelley 2010 Purdue University

Design Assessment: Consumer Reports Style, Todd R. Kelley

Publications

The article analyzes a design assessment-based activity, in which students are asked to evaluate an existing technology through a Consumer Reports-style approach. According to H. Petroski, the exposure of students to several design examples is important to start learning the basic elements needed in the design process. It claims that the activity will enable students to sharpen their knowledge in several areas including identifying design constraints and criteria, training via study of open designs, and practicing engineering design methods for optimization. It suggests that these are important skills for creating the student's capacity to undertake bigger design activities.

The issue of attracting more young people to choose careers in science, technology, engineering, and mathematics (STEM) has become critical for the United States. Recent studies by businesses, associations, and education have all agreed that the United States’ performance in the STEM disciplines have placed our nation in grave risk of relinquishing its competitive edge in the marketplace (e.g., Rising above the gathering storm, 2007). A Congressional Research Service (2006) report stated that, a “large majority of secondary students fail to reach proficiency in math and science, and many are taught by teachers lacking adequate subject matter knowledge” (Congressional ...


Engineering Professional Development Design For Secondary School Teachers: A Multiple Case Study, Jenny L. Daugherty 2010 Purdue University

Engineering Professional Development Design For Secondary School Teachers: A Multiple Case Study, Jenny L. Daugherty

Publications

The effectiveness of teachers has been regarded as crucial to the success of standards-based reform (Fishman, Marx, Best, & Tal, 2003). Research, particularly within science and mathematics, has underscored the need for professional development to help teachers understand (a) subject matter, (b) learners and learning, and (c) teaching methods (Loucks-Horsley, 1999). In addition to focusing on teacher professional development, national reform efforts have also emphasized science, technology, engineering, and mathematics (STEM) education (i.e., Rising Above the Gathering Storm, NRC, 2006). While substantial work has been conducted in mathematics and science, the efforts in technology and engineering education are much less mature. This makes sense given the relatively recent development of the Standards for Technological Literacy (ITEA, 2000) and recent calls for integrating engineering into the K-12 classroom as both an avenue to technological literacy and as a way to enhance the engineering pipeline (Erekson & Custer, 2008; Lewis, 2005; Wicklein, 2006).

The complexity of engineering and its integration into K-12 education, however, have resulted in a variety of issues requiring sustained empirical research (Johnson, Burghardt, & Daugherty, 2008). One particular area of need given the emphasis on teacher effects on student learning is to research engineering-oriented teacher professional development. A lack of publication on the effective practices of engineering-specific professional development projects makes a study investigating mature efforts necessary. Thus, the purpose of this qualitative study was to explore professional ...

Greening The Curriculum: Augmenting Engineering And Technology Courses With Sustainability Topics, Kurt A. Rosentrater, Elif Kongar

Kurt A. Rosentrater

Duties of engineers and technologists often entail designing and implementing solutions to problems. It is their responsibility to be cognizant of the impacts of their designs on and thus, their accountability to society in general. They must also be aware of subsequent effects upon the environment. They need to be able to concurrently satisfy these often competing priorities as well as constraints specific to the technical challenges at hand. Responding to these contending forces are the growing fields of green engineering and sustainable engineering. Both of these areas encompass many concepts, ideas and tools all of which are essential for ...


Facilitating Teaching And Research On Open Ended Problem Solving Through The Development Of A Dynamic Computer Tool, Matthew Verleger, Heidi Diefes-Dux 2010 Purdue University

Facilitating Teaching And Research On Open Ended Problem Solving Through The Development Of A Dynamic Computer Tool, Matthew Verleger, Heidi Diefes-Dux

School of Engineering Education Graduate Student Series

Model Eliciting Activities (MEAs) are realistic open-ended problems set in engineering contexts; student teams draw on their diverse experiences both in and out of the classroom to develop a mathematical model explicated in a memo to the client. These activities have been implemented in a required first-year engineering course with enrollments of as many as 1700 students in a given semester. The earliest MEA implementations had student teams write a single solution to a problem in the form of a memo to the client and receive feedback from their TA. For research purposes, a simple static online submission form, a ...

A statistical analysis and computational algorithm for comparing pairs of tool marks via profilometry data is described. Empirical validation of the method is established through experiments based on tool marks made at selected fixed angles from 50 sequentially manufactured screwdriver tips. Results obtained from three different comparison scenarios are presented and are in agreement with experiential knowledge possessed by practicing examiners. Further comparisons between scores produced by the algorithm and visual assessments of the same tool mark pairs by professional tool mark examiners in a blind study in general show good agreement between the algorithm and human experts. In specific ...

Engineering Students' Definitions Of And Responses To Self-Directed Learning, Jonathan Stolk, Rob Martello, Mark Somerville, John Geddes

John B. Geddes

COLLEGE INSTRUCTORS have struggled with a lack of self-directed learning (SDL) development in their students for many decades. Self-direction is by no means a new topic in teaching and learning, but it is one of growing significance in engineering educational discourse. In 1969, Carl Rogers articulated the need for flexible, independent learners: Teaching and the imparting of knowledge make sense in an unchanging environment. This is why it has been an unquestioned function for centuries. But if there is one truth about modern man, it is that he lives in an environment which is continually changing . . .We are, in my ...
