The document discusses personalized learning environments (PLEs) and whether they render teachers dispensable or help prepare students to learn independently. It suggests PLEs could shift curriculum to help students form their own questions, develop patience with uncertainty, appreciate failure, and learn deeply about their passions. However, true personalized learning gives students autonomy over their education rather than being personalized for them by others like teachers. The key question is whether PLEs are preparing students to learn without teachers or with teachers supporting student-driven learning.
