2153	 Experiments with an Automated Instructional System for Numerical Methods	 A computer system was developed at Purdue University to teach portions of an undergraduate course in numerical methods. Each instructional unit or lesson is divided into three modes of instruction which allow the student to press from a computer-controlled presentation to a student-controlled investigation. The system is designed as a classroom-independent course of study and has been used for two semesters by students in lieu of conventional classroom instruction. Initial measures of effectiveness student acceptance and operational cost are the result of testing the system independent of instructor intervention. The system is operational on a CDC with teletype terminals. computer-assisted instruction numerical methods CAI instructional systems
