Instructional Theory

Instructional theory is a theory that offers explicit guidance on how to help people learn and develop, distinguishing itself from a learning theory by prescribing how to improve instruction rather than merely describing how learning happens on its own. The field is generally traced to the late 1970s in the United States and draws heavily on Benjamin Bloom's 1956 taxonomy of educational objectives; Robert M. Gagne is widely regarded as one of its first major theorists, publishing The Conditions of Learning in 1965, while David Merrill later contributed First Principles of Instruction, identifying instructional methods that apply across teaching situations alongside others suited to particular circumstances. Instructional theory draws on three broader educational perspectives: behaviorism, which explains learning through conformity to reinforced standards; cognitivism, which explains learning through the formation of mental associations; and constructivism, which explains learning as something learners build through activity. These perspectives together inform the instructional design practices that educators use to plan teaching and structure material for effective learning across a wide range of educational settings.
