AIR is evaluating IDEA (Individuals Dedicated to Excellence and Achievement) Public Schools’ implementation of two computer science interventions that aim to (a) increase access to and participation in rigorous mathematics and computer science coursework among students who are traditionally underrepresented and (b) increase the number of teachers with deep content knowledge in computer science and STEM (science, technology, engineering, and mathematics) within schools predominantly consisting of students from low-income backgrounds. The goals of the evaluation are to determine if the two interventions are improving students’ performance on district, state, and Advanced Placement mathematics assessments and if they contribute to postsecondary STEM aspirations.
