This paper is a preliminary report of a pilot study done at the University of Northern Colorado in 1984 using PHOENIX, a mainframe computer based education (CBE) system in a teacher education program. The study deals with the instructional tutorial and a computer based test generation system related to those tutorials. Data on the physiological and psychological factors related to CBE were obtained from 77 students in an educational technology and instructional design program for teachers. Information on the perceived value of computer based education (CBE) by students and achievement gains contributed by CBE are also reported. Brief descriptions of time, terminal availability, lesson format, screen displays, and learning outcomes are discussed. Both tutorial and testing programs were involved in the study. An on-going study which is underway will add to this database with an estimated 1,000 students over 11 courses in 4 subject matter areas. (Author/THC)
