A program was developed to use the PLATO IV system of the University of Illinois to help students solve typical programing problems. The program tries to approximate a near-ideal situation in which each student receives correction of logical errors and comments on good programing practice as he goes along in a one-on-one tutorial environment. The…

A human tutor must have a plan of instruction, but be able to deviate from the plan when the student behavior calls for changes. This paper presents observations of human tutors and describes the FLOW tutor system, a computer-based simulation of a human tutor that is capable of giving advice to a student learning a simple computer language. The…

The development of an interactive error analysis system for a highly interactive programing language compiler is explored. A project is underway at the University of Illinois to automate the teaching of elementary computer science programing language courses by utilizing the PLATO IV interactive computer system. One goal of the project is to…

Intelligent computer assisted instruction (CAI) systems are exemplified by several tutorial systems including Tutor-SCHOLAR, Map-SCHOLAR, NLS-SCHOLAR and SOPHIE. The original SCHOLAR program structure made it possible to model the way human tutors interact with students. Further analyses of tutoring and teaching strategies led to the development…

The use of student proctors or tutors for a Personalized System of Instruction (PSI) has been considered essential; however, the cost of tutorial training programs may be prohibitive. In an attempt to develop an equivalent but less expensive alternative, students (N=219) participated in an evaluation of the use of a VAX computer system as a…

This final report summarizes research findings and presents a model for generative computer assisted instruction (CAI) with respect to its usefulness in the classroom environment. Methods used to individualize instruction, and the evolution of a procedure used to select a concept for presentation to a student with the generative CAI system are…

This paper evaluates the strengths and limitations of a computer tutor designed to help students understand physics concepts. The tutor uses a teaching strategy called "bridging analogies" that previous research has demonstrated to be successful in one-to-one tutoring. The strategy is designed to remedy misconceptions by appealing to existing…
