If I taught my class to those who "previewed the material" I'd be teaching to 1 or 2 students ... maybe.
In reality, the best students do exactly this.

In fact, in my experience it's not even usually possible to read material before the lecture because students are only given at best a vague idea of what specifically is coming next.
Really? That has not been my experience.
Every class I have taught had a detailed syllabus with chapter and page assignments. Generally, they were spot on until the class started getting behind.
For English classes, which book you need to have read is always listed.
Which classes would you be referring to?
