An Engineering Linkage To K 12 Teachers

Abstract

Engineering faculty at Iowa State University have worked collaboratively with teacher education faculty since 1996 to offer an undergraduate course entitled Toying with Technology to elementary and secondary education majors1, 2. The development of this technology literacy course provided students with an appreciation for the technological innovations that surround them. Studies have shown that students form many of their overall career and educational attitudes as early as elementary school. Elementary (and even secondary) schoolteachers who have an appreciation for technology will likely convey that appreciation to their students. This will, in turn, broaden the horizons of these students regarding the opportunities they may have regarding careers in scientific and engineering disciplines. Engineering faculty believe the Toying with Technology course is a component of the long-term recruitment of K-12 students, particularly minorities and women, into technology-based fields3, 4, 5. This course is designed to explain the principles behind many of the technological innovations in wide use today via a collection of hands-on laboratory experiences based upon simple systems constructed out of LEGOs and controlled by small computers. These laboratory experiences are designed to lead students, literally by their hands-on experimentation, through the use of technology in support of many everyday activities. The lab experiences are simple enough to isolate and illuminate the underlying basic principles and yet complex enough to represent real-world examples. Students typically design and construct simple models of real-world systems, including an elevator and its controller, a garage door and its opener, a computercontrolled car, and a house security system. A significant portion of this course is the many field experiences involving K-12 students being facilitated in mobile robotics exercises by the pre-service teachers. The literature in recent years shows numerous papers on mobile robotics1, 2, 6-8, many using LEGOs. There also are many references to engineering outreach efforts3-5, 8-12. During the summer of 2000 a graduate course incorporating these mobile robotics and scanning electron microscope exercises was offered to in-service teachers and teacher education graduate students. Several of the in-service teachers who took this course are now partnered with the current undergraduate students to provide an ongoing relationship among the practicing teacher, the pre-service teachers, the K-12 students, and the engineering faculty. In effect, the practicing teacher's classroom becomes the laboratory for the Toying With Technology course.

The Influence of Aviation Companies’ Perceived Websites Quality on E-Trust

“…Two main reasons were behind this selection. First the selected respondents are already online users; and second previous empirical works have shown that online behavior was not significantly different from a sample (Thakur & Summey, 2007;Gallagher et al, 2001). The questionnaire was pre-tested to ensure readability and validity before distribution.…”

Development of a Hybrid Community of Practice Course Model to Prepare Pre-Service Teachers to Teach Engineering in K-12 (Work in Progress)

“…in elementary education must complete a course in engineering design methods that is taught by faculty from the college of engineering [15]. The University of South Florida offers a course in STEM issues for pre-service middle school math and science teachers that is co-taught by faculty from engineering and education and teachers in a local school district [16], while at Iowa State University, education and engineering faculty jointly teach a class for education majors called Toying with Technology [17], and Hofstra University offers a unique K-5 STEM Education major that includes 4 required engineering education courses that are taught by faculty from the college of engineering [18]. Although all of these programs are promising, the effectiveness of this model of engineering teacher training has not yet been systematically investigated.…”
