The testing and revision phase of REACT (Relevant Educational Applications of Computer Technology) and CUES (Computer Utility for Educational Systems) is summarized. REACT is a training course for teachers and administrators designed to familiarize them with the use of computers for instructional and administrative purposes. REACT course materials are designed for hands-on interaction between teachers and administrators and the computer; training is accomplished by a combination of instructional manuals and interaction with a computer. By the end of the contact year every training manual was revised, based on data from in-house tests, consultant reviews, and results from various test sites. Tests showed that the manuals were effective in either self-instruction or group presentation modes. It was found that the greatest need for assistance with the training program always arose during the set-up phase and, after that, any problems that arose could be handled by telephone. This report contains sample units, a sales brochure from the publisher, and a bibliography of books and articles relating to computers and their uses. (JY)
