<p>Clickers are even used in elementary classrooms now with smart boards. They are called something else and look different, but it’s the same concept. At least they don’t have to be purchased by the families. There are 300 students in one of D’s classes and 120 in another class which are the classes that use clickers.
As for the access codes, she’s already had to take several quizzes online outside of class time. When I was in college we didn’t have quizzes, at least not that I remember. I had maybe 3 or 4 exams per semester with the last one being a final. The access codes are only good for 6 months, so even if she can use the same book next semester (I doubt it though), we’d still have to buy another access code a la carte which costs more than buying it in the book package. </p>
