Which option reflects a commonly used evidence-based teaching strategy in K-12 classrooms?

• A. Explicit instruction, modeling, guided practice, feedback, and formative checks with data.
• B. Rote memorization without feedback.
• C. Unstructured lectures with no guidance.
• D. Silent reading with no guidance.

Answer: (A)

Structured, evidence-based instruction combines explicit instruction with modeling, guided practice, timely feedback, and formative assessments to build mastery. Explicit instruction provides clear goals and step-by-step procedures, so students know exactly what they are aiming to do. Modeling shows precisely how the skill or concept is performed, making the target more concrete. Guided practice offers scaffolded opportunities to apply the new skill with teacher support, gradually releasing responsibility as students gain competence. Feedback gives specific, actionable information about what’s correct and what needs adjustment, helping students correct errors and refine strategies. Formative checks with data continually inform what to reteach, adjust, or accelerate, ensuring instruction stays responsive to students’ actual understanding. This combination supports durable learning and transfer, unlike approaches that rely on memorization without feedback, unstructured lectures with little guidance, or silent reading with no targeted guidance, which miss essential supports for developing skill and understanding.
