The Edgar Dale Cone of Experience summarizes how learners retain information. A person remembers 10% of what they read, 20% of what they heard, 30% of what they seen and 50% of what is seen and heard.
In 2002, this was the first and only “Cone of Experience” reference when searching the OSU site for “Edgar Dale.”
