Collaborative Learning is when students complete a task or goal by working together as a true team.
In collaborative learning, people don’t do it just because it’s a requirement. They like working as a group because they value the contributions of each
group member, and they truly believe that the end result will be better than if they had worked individually. Collaborative learning is not structured by the teacher; instead, the group truly functions as a team. They share authority, accept personal responsibility, and hold each other accountable for their work.
