A nice summary on the student-centred classroom from the TEAL Just Write! Guide (Feb. 2012):
The student-centered classroom involves changes in the roles and responsibilities of learners and instructors, in the delivery of instructional strategies, and in learning itself; these all differ from those in the traditional, teacher-centered classroom. In the student-centered classroom, the learner requires individualization, interaction, and integration. Individualization ensures that learners are empowered to create their own activities and select their own authentic materials. Learners interact through team learning and by teaching each other. During the learning process, learners integrate what they have learned with prior learning and construct new meaning (Moffett & Wagner, 1992).
