There is an assumption that graduate teaching assistants (GTAs) have mastery of the chemistry content they are teaching and preparation to instruct students. However, in reformed classrooms, GTAs may need more support and resources. We designed chemistry rehearsal modules for use in a mixed-reality teaching simulator to help prepare GTAs for…

The present study examined changes in high school biology and technology education pedagogy during the first year of a three-year professional development (PD) program using the INSPIRES educative curriculum. The Next Generation Science Standards (NGSS) calls for the integration of science and engineering through inquiry-based pedagogy that shifts…
