The document discusses differentiated instruction, which is responsive teaching that accounts for differences between students. It involves varying content, processes, products, and learning environments based on students' readiness, interests, and learning profiles. The key aspects of differentiation are:
1) Using pre-assessments to determine students' starting points and tailoring instruction accordingly.
2) Employing formative assessments during instruction to make adjustments that improve understanding.
3) Administering summative assessments after instruction to evaluate mastery of material.
4) Differentiating content, processes, products, and environment based on readiness, interests, and learning profiles to increase the likelihood that each student learns as much as possible.
