This area has been created for academic and clinical educators who are responsible for designing and presenting teaching/learning experiences based on the cognitive disabilities model developed by Claudia Allen and colleagues.  Over time, this area will offer various resources such as handouts, power point presentations, hands-on learning activities, recommended texts, references and audio-visual resources, sample lesson plans, and Q&As relevant to educators and their “learners”, e.g. students, colleagues, non-OTs, clients, and family members. If you have resources you would like to share, resources you would like to have, or questions related to teaching to the  cognitive disabilities model, please contact:
