I like “The Four Stages of Loving Mistakes” from our friends at Floop:

• Normalizing mistakes involves the teacher helping to model an open curiosity towards mistakes.
• Celebration involves finding peers who made similar mistakes and investigating together.
• Analyzing mistakes involves finding patterns in our mistakes.
• Generalizing mistakes involves extrapolating patterns to provide valuable insights for future learning.

Those align with my experience of iterative engineering cultures, where blameless post-mortems are practiced.

The four stages are compatible with learner safety. Try using them in your learning space. Learner safety and iterative cultures go great together.
