Computer assisted instruction system for computational method

This paper discusses the designing process of computer assisted instruction system for computational method by C language and assembly language supported by DOS system environment.Based on the advanced CAI techniques both home and abroad,the interface of the courseware is friendly and convenient for communication between people and computers.The courseware has the promotive function in computational method instruction and contributes to programmed elicitation method of teaching computational methods recursion descent analytical method.By means of the system,it provides process function whose expressions is input via keyboard and analyzed,which is convenient to find solutions to any arbitrary problems of mathematical expressions.For the sake of user’s benefits,and conveniences and according to the connatrural regulation and requirements of CAI,the developers have made optimum design to provides the system with the function fault?to lerant treatment.The designing method is applicable for dealing with general problems in designing CAI software for engineering mathematics.
