Intelligent Computer Aided Instruction In Statics PDF Download

The increased emphasis on fifth-generation computers has prompted much attention on the study of artificial intelligence and the sub-field of expert systems. Expert systems are computer programs which solve expert problems using expert knowledge. The primary emphasis of these programs is human knowledge representation of problems that humans solve. On of the areas where expert systems have been used is in education. The linking of expert systems and traditional Computer Aided Instruction is known as Intelligent Computer Aided Instruction. The purpose of this study is to demonstrate the feasibility of an expert system applied to undergraduate instruction. An expert system was developed to model the problem solving knowledge of Dr. J.L. Meriam from his text Engineering Mechanics Volume I, Statistics. The rules and heuristics for solving two-dimensional truss problems were then implemented in the MRS language. The expert system was then validated by solving problems from the text in the same manner as Meriam. Linked to the expert system were three learning style modules. The learning styles modeled in this study were drill-and-practice, learning-by-example, and a new style called buddy-study.
