Interactive Sprite Programming and Debugging

Students will build on foundational block‑based coding skills to create interactive, multimedia sprite projects that respond to events, use cloning, and run in parallel. The unit emphasizes debugging, reuse (custom blocks and inheritance), hardware transfer to micro:bit, and sharing finished programs.

Learning Objectives

• Analyze event-driven and parallel program behavior by tracing green-flag scripts, shake events, cloned sprites, and concurrent threads to predict runtime outcomes.
• Apply systematic debugging and project-management practices by commenting out code, performing iterative save-test-debug cycles, and resolving logic and runtime errors in multimedia projects.
• Demonstrate integration of multimedia and I/O by implementing costume changes, text-to-speech, instrument sounds, string operations, and transferring a working program to a micro:bit.
• Evaluate and refactor program structure for reuse and sharing by creating and using custom blocks (e.g., makeEmojis), leveraging cloning/inheritance patterns, and preparing the project for publication.
