Feedback Practices
Regular Check-ins
WEEKLY 1:1 STRUCTURE:
┌─────────────────────────────────────────────────────────────┐
│ Duration: 30 minutes │
├─────────────────────────────────────────────────────────────┤
│ │
│ THEIR AGENDA (15 min): │
│ • Blockers and challenges │
│ • Questions about recent work │
│ • Topics they want to discuss │
│ │
│ YOUR FEEDBACK (10 min): │
│ • Specific praise (what went well) │
│ • Growth opportunity (one thing to improve) │
│ • Progress toward goals │
│ │
│ PLANNING (5 min): │
│ • This week's focus │
│ • Support needed │
│ • Action items │
│ │
│ QUESTIONS TO ASK: │
│ "What was the hardest thing this week?" │
│ "What do you want to learn next?" │
│ "How can I better support you?" │
└─────────────────────────────────────────────────────────────┘
Code Review as Teaching
EDUCATIONAL CODE REVIEW:
┌─────────────────────────────────────────────────────────────┐
│ │
│ GOOD FEEDBACK: │
│ "This works! A more idiomatic approach would be │
│ using Array.filter() here. Check out this example: │
│ [link]. Not blocking, but worth learning." │
│ │
│ BAD FEEDBACK: │
│ "Use filter()" (no context, no learning) │
│ │
│ ───────────────────────────────────────────────── │
│ │
│ GOOD FEEDBACK: │
│ "Great solution! One thing I'd change: this │
│ component will re-render on every parent update. │
│ Want to pair for 15 min to explore React.memo?" │
│ │
│ BAD FEEDBACK: │
│ "This is inefficient." (discouraging, no path forward) │
