Dr. Augusto Macalalag Jr., assistant professor of science, technology, engineering, and mathematics (STEM) education, joined researchers and educators from selected universities in the U.S. to develop rubrics for the Professional Development Standards for K-12 Teachers of Engineering. The rubrics were designed to guide school leaders, teachers, and developers in planning, implementing and assessing PD programs for STEM teachers. The meeting was held at the Harpeth Hall School in Nashville, Tenn. in October 2013. It was funded by the American Society for Engineering Education and supported by the National Academy of Engineering.
