With personalized learning, teachers and students collaborate to design the best learning approaches for students, depending on the task and subject. Teachers lead effective and optimally paced instruction and activate and advise students, in ways that accelerate learning and reduce gaps. Students advance through material only after they have demonstrated true mastery of a concept, ensuring they are neither borednor lost. This approach also creates opportunities for students to learn skills and habits of success, such as self-motivation and persistence.
