A key question is who or what will do the personalizing of learning? What level of individual student involvement can and should there be in personalized learning? What roles will the students, teachers, administrators, school boards, ministries, curriculum designers, private companies, parents, classmates, etc. play in personalizing learning?
Will personalizing learning involve forces external to a student (computers, algorithms, teachers and other people at a distance) making judgments about what constitutes a personalized experience for that student? Can this be accurate? How will accuracy be determined? Will this process be just?
What ethical issues do we need to consider concerning the agent(s) of personalization?
