"We might view the movement from teacher-directed to student-driven learning as a set of controls, much like the controls on an audio sound board," write Bena Kallick and Allison Zmuda. For each element of personalization, the teacher can turn the volume up or down, amplifying or reducing the amount of student agency depending on the subject matter and students' needs. In this article, Kallick and Zmuda show how seven elements of personalization (goals, inquiry and idea generation, task and audience, evaluation, feedback, instructional plan, and cumulative demonstration of learning) change as teachers move toward greater student control.
