The instructional development models document the complex process educators use to develop instructional solutions. Models help convey meaning about relationships and processes to facilitate study. The ASSURE model is a procedural guide that integrates technology into teaching. It includes six steps: 1) analyze learners, 2) state objectives, 3) select media and materials, 4) utilize materials, 5) require participation, and 6) evaluate and revise. The concrete-abstract continuum model positions instructional methods on a scale from concrete to abstract based on the level of engagement and active learning.
