The past 30 years have yielded a mature body of research regarding effective professional development for teachers of science and mathematics, leading to a robust selection of professional development programs for these teachers. The current emphasis on connections among science, technology, engineering, and mathematics underscores the need for similar research into the nature of effective professional development for teachers of engineering. With this in mind, this paper completes a review of the literature concerning effective professional development for teachers of engineering, both as a unique discipline and as a context for teaching and learning in other subjects. The results of this review serve as the foundation for five research-based design standards for professional development initiatives in the field of engineering education, which have been published on the American Society for Engineering Education (ASEE) website along with a matrix that will enable providers and consumers of engineering professional development to determine the extent to which a given program focuses on each of those standards.

Cheryl Farmer is the founding Program Manager and Project Director of UTeachEngineering. Funded through a five-year, $12.5 million Math and Science Partnership grant from the National Science Foundation, UTeachEngineering offers a well-designed, well-rounded, design-based high school engineering course that can be implemented at low cost in virtually any setting, as well as a variety of professional development programs for pre-service and in-service teachers who want to add engineering to their teaching portfolio. Prior to co-founding UTeachEngineering, Farmer spent several years managing programs for both K-12 and higher education. Before entering higher education, Farmer worked as a project manager in the environmental field. Her education includes graduate work in mathematics and business administration and a B.

Lisa Guerra has 25 years of experience in the NASA aerospace community. Guerra is currently working with the UTeachEngineering program. She recently completed a four-year assignment from NASA headquarters to establish a systems engineering curriculum at the University of Texas, Austin, as a pilot for national dissemination. Her efforts in systems engineering curriculum can be located at http://spacese.spacegrant.org/. Guerra's most recent position at NASA Headquarters was Director of the Directorate Integration Office in the Exploration Systems Mission Directorate. In that position, her responsibilities involved strategic planning, international cooperation, cross-directorate coordination, architecture analysis, and exploration control boards. Guerra also spent three years at the Goddard Space Flight Center as Program Integration Manager for future high-energy astrophysics missions, particularly the James Webb Space Telescope. She began her career at the Johnson Space Center working for Eagle Engineering and SAIC, focused on conceptual design of advanced spacecraft for human missions to the moon and Mars. Guerra earned a B.S in aerospace engineering and a B.A. in English from the University of Notre Dame. She received a master's of science degree in aerospace engineering from the University of Texas, Austin.

is the founding program director of UTeachEngineering. In this role she has led the successful development and launch of the design-based high school engineering course Engineer Your World and has overseen the creation of degree programs for pre-service and in-service teachers of engineering at The University of Texas. Ms. Farmer is co-leading ongoing national efforts to define standards for professional development for K-12 teachers of engineering.

at Austin. He is the author of six books and more than 200 papers in areas ranging from coal liquefaction and heavy oil chemistry to the chemistry of urban atmospheres. For the past decade, his work has focused primarily on urban air quality and the development of materials for environmental and engineering education. Allen was a Lead Investigator for the first and second Texas Air Quality studies, which involved hundreds of researchers drawn from around the world, and which have had a substantial impact on the direction of air quality policies in Texas. He has developed environmental educational materials for engineering curricula and for the University's core curriculum, as well as engineering education materials for high school students. The quality of his work has been recognized by the National Science Foundation (through the Presidential Young Investigator Award), the AT&T Foundation (through an Industrial Ecology Fellowship), the American Institute of Chemical Engineers (through the Cecil Award for contributions to environmental engineering and through the Research Excellence Award of the Sustainable Engineering Forum), the Association of Environmental Engineering and Science Professors (through their Distinguished Lecturer Award), and the state of Texas (through the Governor's Environmental Excellence Award). He has won teaching awards at the University of Texas and UCLA. Allen received his B.S. degree in chemical engineering, with distinction, from Cornell University in 1979. His M.S. and Ph.D. degrees in chemical engineering were awarded by the California Institute of Technology in 1981 and 1983. He has held visiting faculty appointments at the
