Web-based tutoring and testing in a computer networks course

In this article, a Web interface for a course on computer networks is presented. This Web interface integrates course material, student registration, objective exams, and grading. The system uses a Microsoft Access database that stores information about students, including status and grades, and a collection of questions for the quizzes and the Final exam from which a random sample is chosen to generate a test dynamically. Options included in the package are open-book versus closed-book exams, timed exams versus open-time exams, and penalty versus no penalty in grading. The implementation relies on scripts written in Microsoft Visual Basic that query and update the Access database, all running under the Windows NT operating system. (C) 1999 John Wiley & Sons, Inc.
