Year Six Annual Report: Activities, Findings And Evaluators' Reports, Ncete Faculty

Reports to NSF

The National Center for Engineering and Technology Education (NCETE) is a collaborative network of scholars with backgrounds in technology education, engineering, and related fields. Our mission is to build capacity in technology education and to improve the understanding of the learning and teaching of high school students and teachers as they apply engineering design processes to technological problems.

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.

Xperts And Novices: Differences In Their Use Of Mental Representation And Metacognition In Engineering Design, Raymond Anthony Dixon

Dissertations

Research shows that mental representation such as analogical reasoning is a fundamental cognitive tool for design problem solving (Daugherty & Mentzer, 2008; Hey, Lensey, Agogino, & Wood, 2008; Lewis, 2008). Not much is known, however, about the way students and professional engineers actively generate and change their mental representation when solving a engineering design problem. There are very few studies that show how different types of mental representations; such as metaphors, propositions, and analogies; interplay with higher order cognitive processes; such as planning, monitoring, and evaluation; as engineering designers navigate their problem and solution spaces. This empirical study investigated the …

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 …

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.

Stem Education And Leadership: A Mathematics And Science Partnership Approach, Chris Merrill, Jenny Daugherty

Publications

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 Research …

Engineering Student Outcomes For Infusion Into Technological Literacy Programs: Grades 9-12, Craig Rhodes, Vincent Childress

Publications

In 2004, the National Center for Engineering and Technology Education (NCETE) secured funding from the National Science Foundation (NSF) to infuse engineering design into the schools through technology education. In order to reach this goal the researchers, in cooperation with NCETE, conducted a two phase study to identify outcomes for high-school students studying engineering. The first study (referred to as a Phase I) focused on students who intended to enter an engineering program after high school, answering the question:

What are the engineering student outcomes that prospective engineering students in grades 9 through 12 should know and be able to …
