The development of a computer-based, university-wide testing system at Brigham Young University is discussed, as is its application to two large-enrollment math classes. The hardware configuration, software applications, general philosophy, budget, and personnel requirements of the system are also explained. Development of the system over time is explained as is the flow of students and faculty through the system. The organization of the two math courses is described and the philosophy and constraints which molded the classes into their present management structure are explained. The interaction between the testing system and the students is analyzed, and problems of the course co-ordinators concerning the testing system are discussed. The results of the interaction between the system and the math classes is treated and comments are made regarding the advantages and disadvantages of such an interaction. (Author/GK)
