Create opportunities for students to collaborate and explain their thinking.
Students learn better by engaging with "more capable others."
"Students who do the talking and the doing, do the learning." ~Eric Jensen
Notice that these practices are at the bottom of the learning pyramid.
Effective communication and collaboration are essential to becoming a successful learner. It is primarily through dialogue and examining different perspectives that students become knowledgeable, strategic, self-determined, and empathetic.
Moreover, involving students in real-world tasks and linking new information to prior knowledge requires effective communication and collaboration among teachers, students, and others. Indeed, it is through dialogue and interaction that curriculum objectives come alive.
Collaborative learning affords students enormous advantages not available from more traditional instruction because a group--whether it be the whole class or a learning group within the class--can accomplish meaningful learning and solve problems better than any individual can alone.
This focus on the collective knowledge and thinking of the group changes the roles of students and teachers and the way they interact in the classroom. Significantly, a groundswell of interest exists among practitioners to involve students in collaboration in classrooms at all grade levels.
Collaboration is not something new!!!
