The myth of the average student
"When thinking about taking a group of students to the beach, it goes without saying that we would never expect a group of 30 people to wear the same style or size bathing suit. Just plain ridiculous. We also would never expect the same group of 30 to pack the same snack, lunch, or beverage. There are many variables that result in the fact that people need to pack different foods and beverages. And we can be pretty certain that in this group of 30 some will want to tan and use a low-SPF sunning lotion, while others will range up to 50 or even 100 SPF.
So.... Why would we expect all 30 to experience the learning process in the same way?
