The CS research focus is socially relevant computing and analytics including serious games, interface design, critical infrastructures, novice programming environments, intelligent tutoring systems, machine learning, and data analytics. The RET immerses 14 participants (8 in-service, 3 pre-service, 3 REU) in a vibrant community in teams of 4-5 to contribute to ongoing research. Plans for developing curricular modules linked to the research experiences include workshops on equitable and culturally relevant CS curricula, and intensive workshops with peer feedback for development of modules. Plans for sharing modules with K-12 teachers include teacher presentations and sharing in national digital libraries. Activities include orientation, mentor training, weekly workshops, 2 research/curricula presentations/RET. Our objective is to create a collaborative culture, promote individual research contributions, and create culturally responsive and inclusive curricular modules.Teachers to be recruited include high school STEM/CS teachers serving schools with significant representation from underrepresented groups, through NC Dept. of Public Instruction. We will recruit pre-service teachers from NCSU College of Education and other education departments, and CS REUs from STARS Computing Corps. The intended impact on participating teachers is to increase their CS knowledge, efficacy, research and presentation skills; and to increase retention and engagement of their students. The intended impact on broadening participation of underrepresented groups in CS is to create high levels of student engagement particularly for females, African-Americans/Blacks, Hispanics/Latinx and new knowledge about CS and careers. Plans for academic-year follow-up and outreach activities and dissemination include RET Teams and mentors support teachers in classroom implementation; pre-service teachers observing classes; and two workshops to reinforce pedagogical and research knowledge gained.
