There are many advantages of group learning. Not only is it economical, it also allows students to practice different methods of learning and understanding in lessons.
In group lessons, students are able to come to a more complete understanding of the topic or question at hand by comparing their knowledge and answers with others. By explaining their answers to others they gain a more sound understanding. In addition, individuals in the class who have better skills in certain areas, serve as models to the rest of the class and motivate the others to work hard and do their best.
When discussing controversial topics, group classes have more ideas and more opinions to offer, which promotes a more sophisticated way of thinking. In group classes students can bounce of one another and there is a healthy competition between students to strive to be the best!
