The National Science Foundation STEM Guitar Project provides innovative professional development to high school and community college faculty. Faculty will take part in an intense five day guitar design/build project. Each faculty member will build his/her own custom electric guitar and will engage in student centered learning activities that relate the guitar design to specific math, science and engineering topics. Participants will leave this weeklong experience with their custom-made guitars, curriculum modules with short term assessments that can be immediately integrated into the faculty teams school curriculum, and much more. The institute application process is open to all STEM educators primarily focused in the 9-12 High school grade level, community college and freshman/sophomore university instruction.
