This document discusses the evolution of education from a one-size-fits-all approach to a more differentiated and student-centered one. It notes that while teachers once taught the whole class the same material in the same way, it is now recognized that students learn differently and have different needs, interests, and abilities. The document advocates giving students ownership over their learning by connecting lessons to their interests and passions, encouraging self-assessment, and allowing students to demonstrate learning in multiple ways. It provides examples of using diagnostic assessments, individualized online tasks, student portfolios and blogs, peer assessment, and reflection to help teachers understand each student's strengths and needs and help students track their own progress and growth.
