10 is a small number. There's a middle ground. When I studied, we had lectures for all students, and a similar amount of time in "work groups," as they were called. That resembled secondary education: one teacher, around 30 students, but those classes were mainly focused on applying the newly acquired knowledge, making exercises, asking questions, checking homework, etc. Later, I taught such classes for programming 101, and it was perfectly doable. Work group teachers were also responsible for reviewing their students' tests.

But that commercially oriented boards are ruining education, that's a given. That they would stoop to this level is a bit surprising.
