What is a key characteristic of Mixed-ability grouping in classrooms?

• A. Mixed-ability groups promote cooperative learning
• B. It enforces strict ability tracking
• C. It isolates advanced students
• D. It eliminates the need for shared goals

Answer: (C)

Mixed-ability grouping centers on having students of different skill levels work together in the same groups, which naturally supports cooperative learning. In this setup, students share ideas, explain concepts to peers, and help one another reach common objectives. The diversity in ability means that peers can model thinking in new ways and provide immediate feedback, creating a collaborative learning environment where everyone moves forward together.

This makes the idea of promoting cooperative learning the best fit for a key characteristic. It goes against isolating advanced students, which is more characteristic of ability tracking, and it isn’t about enforcing strict tracking or eliminating shared goals—both of which would undermine the collaborative, goal-oriented nature of mixed-ability work.
