The purpose of this research was to define a feasible set of inputs, functions, rules, and an algorithm applicable to a tutorial session that approximated the analytical skills of a teacher. This research would address the following two questions: 1. Given realistic values for the number of actions, functions, and rules, together with an algorithm for generating tutorial responses for the user, is it feasible to perform the required computations in a timely manner. "Timely" indicates a computation that can be performed in less than 0.5 seconds using a commonly affordable i486-DX 66 MHz based personal computer. 2. Given realistic values for the number of actions, functions, rules and an algorithm for generating tutorial responses for the user, are the responses a reasonable approximation of the advice that a real teacher would provide. Based on a computational analysis of the functions and decision table processing algorithm, it was possible within the lessons actually tested to have provided responses with a maximiun computational delay time of 0.0035 seconds. This delay time is well within the proposed restriction of a maximum 0.5 second delay.
