I'm one who thinks that teaching books should have a question-and-answer format with the ability to discuss the subject after it's read AND a quick quiz to make sure the reader has absorbed the studied subject. Otherwise, it's very easy to read without absorbing any knowledge. I would even go as far as having the sections written in the same way as a newspaper article. With a catchy title and a format that gives the who, when, where, why, and how. At least, the books for the introductory courses should have that format. Current textbooks just flood the students with facts with little absorption. One big problem is that the sections are too long and it becomes a struggle to power through the section which leaves less energy to absorb the subject so my format would catch the reader's attention without feeling exhausted. There's such thing as mental exhaustion. Doing whatever is needed to minimize it should be a goal worth pursuing.
