Assess students' ability to analyze simple block-based maze-solving programs by comparing two or more scripts that use sequencing, loops, and conditionals. Students should identify structure (sequence, loop use, conditional branching), estimate or count steps/iterations, determine which program completes the maze faster with justification, spot redundant moves or unreachable branches, and suggest small efficiency improvements. Scope: elementary grid mazes and typical Scratch-style blocks; focus on logical reasoning and comparative efficiency rather than code syntax.
