Teaching Textbooks™ is a math curriculum based on 3 easy steps: watch the lesson, do the problems, and watch a tutor explain the ones you missed. Teaching Textbooks™ were designed specifically for independent learners (they focus on teaching/explanations). From the website:
A Teaching Textbook™, with its approximately 700 pages of text and 120 – 160 hours of teacher instruction on CD-ROM, is both a teacher and a textbook combined into one. And the CD-ROM teaching isn’t just abstract lectures either. There are also down-to-earth, audiovisual step-by-step explanations for every single one of the almost 3,500 problems in the book … [The Teaching Textbook™] introduces proper terminology only after first presenting the underlying concept in plain language.
