Peer-mediated Instruction and Intervention (PMII)

With a foundation in behaviorism and social learning theory,1 PMII involves systematically teaching peers without disabilities ways of engaging learners with ASD in positive and meaningful social interactions.2-4

What Will I Learn?

The AFIRM model guides the learner through four lessons to facilitate:

  • Learning basic knowledge about peer-mediated instruction and intervention (PMII).
  • Applying PMII in activity based scenarios that promote real-world application.

The PMII module will take approximately 1.5 to 2 hours to complete. However, the module is broken into individual lessons to help guide your learning:

Lesson Time to Complete
A Case for PMII 10 minutes
Lesson 1: Basics of PMII 20 minutes
Lesson 2: Planning for PMII 25 minutes
Lesson 3: Using PMII 25 minutes
Lesson 4: Monitoring PMII 25 minutes
