Which of the following is one of the five guiding principles of cooperative learning?

Positive interdependence is indeed one of the five guiding principles of cooperative learning. This principle emphasizes that in a cooperative learning environment, students work together towards a common goal and rely on one another's contributions to succeed. Each member of the group has a specific role that is tied to the success of the whole group, fostering a sense of teamwork and mutual support. This encourages students to not only collaborate but also to develop social skills and responsibilities.

In contrast, teacher-led instruction, individual competition, and standardized assessments do not align with the collaborative ethos of cooperative learning. Teacher-led instruction tends to focus on direct delivery of content by the teacher, limiting the interactive aspect vital to cooperative learning. Individual competition is at odds with cooperative principles, as it fosters an environment where students prioritize personal success over collective achievement. Standardized assessments often emphasize individual performance metrics, which can undermine the collaborative learning experience that positive interdependence aims to promote.
