Instructional design is the framework for increasing the effectiveness, efficiency, and appeal of curriculum needed to maximize learning. An effective curriculum is designed to facilitate the acquisition of skills and knowledge aligned with standards incorporating best practices in design and pedagogy. Curriculum ranges from lessons developed by teachers to professionally published textbooks. A curriculum should be constructed to include evidence-based practices and practice elements that are well matched to each lesson. The curriculum should incorporate the following criteria in its design: it aligns with standards, research of sufficient quality and quantity is available, levels of competency are defined, high rates of responding are embedded, opportunities to provide feedback for correct answers is addressed, corrective feedback and remediation are designated, scope and sequencing that lead to increasing levels of difficulty are spelled out, mastery-based instruction is required, and formative assessment is specified. In the end, for maximum effectiveness, lessons need to be linked to “big ideas,” those core concepts, principles, theories, and processes that provide instruction with meaning and context.
