Your student may have told you about working with new team members. In a student-centered classroom, teachers have students change teams periodically. This allows students to collaborate with others. Research has shown that students who work in a collaborative problem-solving situation show higher achievement, increased retention, greater intrinsic motivation, higher self-esteem, and a better attitude toward teachers and school, to name a few.
