Using Code Replay to Understand Student Learning
Turn revision history into better instructional feedback.
Request instructor accessSee how it worksA practical feedback conversation
Review a student's sequence of edits to an average function. Identify when they added an empty-list check and ask what prompted the change. Focus the conversation on debugging strategy, not whether their typing speed looks suspicious.
Reflection checklist
Choose one meaningful revision; ask the student to explain it; connect the discussion to a learning objective; avoid treating replay as a definitive authorship detector.
Observe development
Replay can show edits, attempts, and corrections that are absent from the final code.
Find teachable moments
Look for repeated errors, strategic changes, and points where additional instruction may help.
Respect context
Replay is one signal among many. Interpret it with the assignment requirements and student explanations.
