Collaborative learning involves students working together to achieve a common goal or task. Research shows that people learn more effectively through collaboration, retaining 10-95% more of what they learn depending on the level of interaction. In the past, key skills for employers included reading, writing and computation, but now interpersonal skills, problem solving and teamwork are most important. Collaborative learning develops critical thinking, communication skills and a sense of community. It motivates students and helps them learn more while building confidence, leadership and social skills.
