The instructional development models document the complex process educators use to develop instructional solutions. Models help convey meaning of complex concepts through relationships and processes. The ASSURE model is a procedural guide that integrates technology into teaching. It includes six steps: analyze learners, state objectives, select materials, utilize materials, require participation, and evaluate. The concrete-abstract continuum model positions instructional methods on a scale from concrete to abstract based on the level of learner participation and sensory experience.
