A pre-service pathway for preparing future ap cs principles teachers

The surge of interest in K-12 computer science (CS) over the past decade has led to a deep need for a corresponding expansion of trained teachers. The primary focus of most K-12 CS teacher professional development has been for current in-service teachers who have little background in CS. To raise the importance of CS within Colleges of Education, we believe that new pathways and experiences are needed for pre-service Education majors to learn more about authentic CS topics and pedagogy. This experience report summarizes our efforts over the past two years to prepare Secondary Math Education (SEMA) majors to teach AP CS Principles (AP CSP). Our approach consists of the following curricular activities: 1) a two-course sequence, with the first course mapping to the content topics of the AP CSP Curriculum Framework, and the second course consisting of a reflection of CS methods and pedagogy, including opportunities for SEMA students to develop and present their own AP CSP lesson plans; 2) opportunities for SEMA students to observe AP CSP classrooms in local high schools through our partnership with experienced AP CSP teachers; 3) summer participation in a College Board AP Summer Institute for AP CSP, and 4) a six-week ETS Praxis CS preparation modules-based course, offered to both pre-service SEMA students and in-service teachers. We summarize our lessons learned and present results that suggest our approach is preparing pre-service students with pedagogical and content knowledge that meets or exceeds current in-service training models (including an analysis of recent Praxis results for CS certification in our state).
