What’s the purpose of highlighting the text in the textbook?
A. The highlighting is meant to emphasize the most important points in a lesson. It tends to increase student reading comprehension and make it easier to go back and review material that has already been covered. That can be particularly helpful with the Teaching Textbook program, since every problem set uses the review method. Also, some students just want to watch the lectures on CD (instead of reading the lessons in the book) and then only read the highlighted text as a reinforcement.
