Every so often I encounter a discussion with someone who doubts whether or not class size really matters for effective teaching and learning. I’m sure there’s evidence to support this, but I usually respond by saying that a class of 21 or less is more than manageable. I don’t know why this is, though, but every student over 21 is noticeable … up until about 28, and then it’s just a big class. Every student less than 21 isn’t nearly as noticeable. Speaking from my own experience, in a class of 21 or less it feels like it’s possible to get to work with each student.
Then I ask the inquisitor to picture spending a weekend afternoon with seven (or more) children and/or teenagers in their house. Like really … close your eyes and picture what would it look like? What would you do to prepare for their arrival? Would it be noisy? Would it be enjoyable? Would you want a break? Or five?
Then I explain that that is exactly the difference between 21 and 28, except that there’s already 21 children and/or teenagers in the room.
That’s why class size matters.
