CORE DEFINITION

Successive Approximation Model, an agile instructional design approach that uses small iterative cycles (design-prototype-evaluate) to rapidly develop training content, replacing the linear ADDIE process.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

Agile instructional design. Shortens development cycles and reduces design risk through rapid prototyping and user testing.

anchor

Anchor fast decisions

Addressing the drawbacks of the traditional ADDIE linear process (long cycles, expensive rework), SAM uses 'iterative approximation': quickly create a tangible prototype (rather than a detailed plan), let users try it early and provide feedback, then revise in successive rounds. Errors are caught at low-cost stages rather than after delivery.

MINIMUM ACTION

In progress 0/5

Practice this model in one real situation:

Preparation: Gather stakeholders, clarify business goals and constraints.
Design prototype: Use simplified samples (sketches/demos) to quickly present core ideas.
Evaluate and iterate: Collect feedback from user testing, revise the prototype.
Production: Once the prototype is stable, create the final content.
Continue small-step optimization until launch.
