A Hypermedia Computer-Aided Parasitology Tutoring System.
Theodoropoulos, Georgios; Loumos, Vassili
A hypermedia tutoring system for teaching parasitology to college students was developed using an object oriented software development tool, Knowledge Pro. The program was designed to meet four objectives: knowledge incorporation, tutoring, indexing of key words for Boolean search, and random generation of quiz questions with instant scoring. The educational material incorporated in the form of text and/or images with their relational linkages serve as the domain of the system. The tutoring system contains a graphical user interface which allows the user to access the educational material in four different interactive modes: Course, Review, Reference, and Self-Evaluation. Indexing of keywords is accomplished by using a program which first alphabetizes the words of the entire text and then filters out common words. This process leads to the creation of an indexed keyword database which is then used for Boolean searches. Quizzes are generated randomly by using a multiple-choice question and answer database. The main advantage of this system is that it allows the student to interact with the computer-tutor at his or her own pace for self-learning and auto-evaluation. A limitation of the program is its inability to support extended queries due to its reliance on the built-in Knowledge Pro facility. (Contains 26 references.) (AEF)
