This document discusses strategies for creating the right level of challenge in teaching and learning. It emphasizes that challenge should be at the zone of proximal development where tasks are difficult but still possible. Checklists and rubrics can help students and teachers understand expectations and progress. Praise should focus on effort, strategies and progress rather than innate ability so students see challenges as opportunities to learn and improve. Creating the right environment and high expectations can help ensure all students benefit from an appropriate level of challenge.
