Teacher shortages in K–12 computer science (CS) education negatively impact students’ access to CS courses, exposure to CS concepts, and interest in CS-related careers. To address CS teacher shortages, this study seeks to understand factors related to expressing a preference to teach CS among prospective teachers. The study team analyzed data from 27,700 prospective teacher applications accepted into the 2016–2020 Teach For America (TFA) corps (cohorts). The TFA corps is an alternative teacher development program that recruits and prepares participants to obtain their teaching certification while they work for at least two years in underserved communities on a temporary teaching license. Study results show that earning at least one postsecondary CS credit and majoring in CS are positively associated with these prospective teachers’ preference to teach CS. Findings indicate that among these accepted TFA applicants, a larger proportion of male applicants and racially minoritized applicants earned a postsecondary CS credit, majored in CS, and preferred to teach CS compared with female applicants and racially non-minoritized applicants. This study lays the foundation for future explorations of whether early exposure to CS could increase prospective teachers’ interest in teaching CS and reduce CS teacher shortages in K-12 settings. Findings from this study can also serve as a precursor to developing policies that result in a CS teacher workforce that is more representative of students enrolled in K-12 public schools. 

In K-12 education, nearly all e"orts focused on expanding computer science education center on the induction of new computer science teachers, with very little attention given to support the ongoing needs of experienced computer science teachers. More seasoned teachers bene!t from deepening their content knowledge, peda gogical practices, and knowledge and capacity to provide equitable and inclusive learning experiences that results in students feeling a sense of belonging in computer science. This panel will discuss (a) the needs of experienced CS teachers from a variety of perspectives, including teacher education researchers, professional development leaders, and high school practitioners and teacher facilitator, and (b) collectively outline a research and practice agenda that focuses on supporting, retaining, and further developing experienced teachers through expanded professional development, leadership opportuni ties, and community for CS teachers. 

Computer science (CS) education is plagued by a gender divide, with few girls and women participating in this high-status discipline. A proven strategy to broaden participation for girls and other underrepresented students interested in CS is the availability of teacher preparation that requires classroom teachers to grow their knowledge of CS content as well as the pedagogical practices that enhance inclusive learning opportunities for historically underrepresented students. This case study describes the design and impact of an Online Professional Development (PD) for CS teachers, a year-long PD program aimed at broadening participation in the United States. Using survey and observation data from more than 200 participants over three years in PD settings, this paper examines how the design of an online learning community model of PD provides an inclusive venue for teachers to examine their belief systems, develop inclusive pedagogical practices, and collectively transform the culture of CS classrooms to places that support all learners. Findings suggest that purposeful facilitation creates a transformative culture of “shared experience” whereby facilitators and groups of teachers engage in collaborative lesson planning and debriefing discussions, in both synchronous and asynchronous sessions. This case study can inform other online PD efforts aimed at broadening participation in computing.
