"A NOVEL TEACHING DEVICE To the Editor: Being increasingly worried about the cost wd + scheduling problems associated with modern chemical education, I was delighted to see the suggestion of White and Steed (J.Chem Educ. 50,554 (1973) for making audio-tutorial programs cheaper and portable by replacing the conventional slides with photos mounted in a fe ring binder. [believe we can do even better. Let us have the audio tapes transcribed, cut up the typed version, and mount the appropriate words along with the photos in the binder; this will be even more portable and with the appropriate advances in technology, perhaps even cheap enough for each student to have his own. I think it would be useful for such a device to have a name. I propose that it be called a Bound Organization of Knowledge (BOOK). The potential is terrific: freed from the scheduling restraints of cassettes and projectors, students will be able to use their BOOKS for truly self-paced learning. BOOKS can be used anywhere, even dormitory rooms; and BOOKs may be kept for future reference. I would appreciate corresponding with any others who share my enthusiasm for BOOKS and their possible advantages.
