Which of the following is a key feature of cooperative learning?

A key feature of cooperative learning is the emphasis on collaborative tasks in diverse groups. This approach involves students working together in small groups where they can share different perspectives, skills, and knowledge. The diversity within these groups not only enhances the learning experience but also helps to build essential social skills, such as communication, conflict resolution, and teamwork.

In cooperative learning, students are encouraged to engage with one another, support each other's learning, and take on shared responsibilities for group outcomes. This kind of interaction fosters a conducive environment for learning, as students can learn from their peers and gain a deeper understanding of the material through discussion and collaboration.

The other options do not align with the core principles of cooperative learning. For instance, individual assessments typically focus on personal performance rather than group dynamics. Competitive tasks can create a win-lose scenario that discourages collaboration, while teacher-led discussions generally place the emphasis on the teacher's input rather than on student collaboration and interaction.
