Which combination represents evidence-based strategies for differentiating instruction in a heterogeneous class?

• A. Rigid grouping, identical assignments, single-input mode, and infrequent assessment.
• B. Flexible grouping, tiered assignments, varied input/output modes, and ongoing formative assessment data to guide grouping and supports.
• C. No data used to adjust instruction.
• D. Treat all students the same regardless of readiness.

Answer: (B)

Differentiation in a diverse classroom hinges on shaping instruction to each student’s readiness, interests, and learning style, and doing so with flexible, data-driven practices. Flexible grouping lets students move between groups as their understanding shifts, so instruction stays appropriately challenging and supportive. Tiered assignments provide multiple paths to the same objective, giving all students access while varying depth or scaffolds. Varied input and output modes acknowledge that learners take in and show understanding in different ways, whether through reading, listening, visuals, or hands-on activities. Ongoing formative assessment data then guides how groups are formed and what supports or task adjustments are offered, keeping instruction responsive to progress.

The other approaches don’t fit this approach. Rigid grouping, identical assignments, a single input mode, and infrequent assessment ignore differences in readiness and learning needs. Not using data to adjust instruction misses how students actually progress, and treating all students the same overlooks individual strengths and challenges.
