Pearson's Learning Foundations describe the optimal conditions for learning and reflect the learner experience Pearson hopes their products will create. Pearson does this by incorporating the Learning Design Principles. Each of the Learning Design Principles goes into detail about a key principle, supporting product design and marketing by describing: (1) the research that informs the principle; (2) why it matters in learning; and (3) how to apply it in practice. This document discusses the components of evidence-centered design (ECD), which is a four-component framework for designing assessments to reveal meaningful information about learning and to support learning through effective instructional design.
