This paper discusses how to develop a computer-aided instruction (CAI) software system on Artificial Intelligence (AI). The program was written in Visual Basic 6.0, which is an object-oriented language. Students can install this CAI software system on the Windows 98 before the course starts. They can do the preview before class and enhance their concepts of AI using the example programs. The examples of various programs are included for students to practically implement the theories. The main point of designing this CAI software system is to activate students' learning motivation with lively windows interface, to guide the students to learn actively, to put what they learned about AI into practice, and to conceptually help students design their own programs.
