We report on the potential of higher education science faculty involvement in a K-12 scientist-teacher partnership as a source of faculty professional development (PD). Participating higher education science faculty members were paired with middle or high school science teachers to create online, technology-enhanced curricular materials in a range of disciplines for middle and high school science classes using innovative, open-source software created for the project. The same pairs designed and taught associated PD workshops to participating in-service teachers during a summer institute. The activities and professional development cover Earth and space science, physical science, and life science. Survey results on higher education faculty involvement, and attitudes indicate that this process represents a valuable form of faculty PD. It also provides a foundation for future collaboration and network building., There is a growing concern about how best to support students entering college to pursue and succeed in coursework in science, engineering, and mathematics (STEM). This need has also drawn [...]
