When student projects culminate with an artistic performance, says Brown education professor Eileen Landay, they set in motion a “community of practice” that opens students up to learning, as her diagram below shows. As they build skills in repeated rehearsals, she said, they regulate their own behavior; and the feedback they get has an obvious, logical purpose. “It creates a balance between product and process,” Landay says, “between knowing and being able to do.”
