About TutorText dot org

TutorText was a pioneering series of interactive books, published by Doubleday, which used a gamebook-style format to teach a wide variety of subjects to a mainstream audience. The concept of using interactive text was originally called Programmed Learning by behaviorist BF Skinner in 1958. You can read about the whole series on Demian's Gamebook Web Page.

Tutortext.org's mission is to bring some of Doubleday's original textbooks into the 21st century.

The texts published on this site are indexed in the menu at the top right of the screen. Currently the following titles are under development: Adventures in Algebra.

At the beginning of each book, it has an important note, surrounded by a box, such as this one for Adventures in Algebra:


This is not an ordinary book. The pages are numbered in the usual way, but they are not read consecutively. You must follow the directions which you find at the bottom of each page.

You will find that reading this book is very much like having an individual tutor. The book will continually ask you questions and correct errors as well as give you information.

Your progress through this course will depend entirely on your ability to choose right answers instead of wrong ones---and by your endurance. The course is divided into chapters, and a number of short learning sessions produces better results than a few long ones.

Follow the instructions and you'll find it's impossible to get to the final page without mastering the fundamentals of Algebra.
