CLIOTUTOR is a computer-assisted instructional package of 30 tutorial lessons keyed to a standard text and operated with a VAX computer system. Western Michigan University, a member of the CLIOTUTOR consortium, operates its own copy of the program in conjunction with a redesigned two-semester freshman history course. CLIOTUTOR provides a half-hour lesson weekly for each student on questions related to assigned text material. The major goal for using CLIOTUTOR is to make students responsible for learning text material outside class, so classroom sessions can be used for audiovisual presentations, directed writing assignments, and discussion of more complex issues. A secondary goal is instructional cost-effectiveness. Two faculty members administer CLIOTUTOR for three to four sections of a freshman Western civilization course totaling 150-200 students. Some students repeat lessons as review before exams. Informal surveys, personal interviews, and faculty observation suggest that most students enjoy working with CLIOTUTOR and find it an effective way to understand and remember text material. It is particularly appreciated by students whose reading comprehension is modest or poor. Students' major complaint is limited access to the terminals. Faculty feel students understand text material better when they come to class. (MSE)
