Gagne is associated with which of the following?

Robert Gagné's central contribution to educational psychology is his theory of the conditions of learning, in which he argued that learning is not one undifferentiated process but unfolds in a hierarchical order: simpler forms of learning (such as signal learning and stimulus-response association) act as necessary prerequisites for progressively more complex forms (such as concept learning, rule learning, and problem-solving). Every higher capability in this ladder depends on the learner having already mastered the capabilities beneath it.

Because this ladder of prerequisite-to-complex learning types is Gagné's defining idea, his name is specifically linked with a Hierarchical Order of Learning (also known as Gagné's hierarchy of learning types or his conditions-of-learning framework).

• Theories of Learning is a broad umbrella term spanning the work of many psychologists (behaviourist, cognitive, constructivist perspectives) — it is too generic to represent Gagné's own distinguishing framework.

• Evaluation of Learning concerns measuring and assessing learning outcomes, a domain built around taxonomies of educational objectives and assessment design, not Gagné's ordering of learning types.

• Management of Learning concerns organising and controlling the classroom or instructional environment — a matter of instructional/behavioural management, unrelated to Gagné's specific sequencing framework.

So among the given options, the Hierarchical Order of Learning is the one that captures Gagné's specific and well-known contribution.
