This presentation discusses strategies for meeting the needs of diverse learners in the core classroom. It notes that while classes are often "leveled," students still have a wide range of individual strengths and weaknesses. The presentation recommends that teachers use formative assessments and data gathered from student work to group students based on their specific needs, whether it be reteaching, scaffolding, or extension. It emphasizes keeping groups small and focused on one learning target. Teachers should involve students in self-evaluation and goal-setting to increase awareness of their own progress. By celebrating growth, teachers can motivate further learning.
