What Are Case Studies?

These deep-dive analyses explore:

Algorithm Evolution: From brute-force to optimized solutions
Refactoring Strategies: How to improve code structure and performance
Teaching Approaches: Classroom strategies and inquiry-based prompts
Professional Growth: How teachers can model continuous learning
Standards Alignment: Mapping to CSTA Teacher Standards and AP CSA Learning Objectives

Each case study documents the iterative development process, including false starts and corrections, to provide an authentic view of problem-solving.
