Designing and Implementing Two Internet Based Exam Systems Using Synchronous and Asynchronous Models

In this paper, two different systems for taking exams through the Internet are described and analyzed. They have been designed and executed in Yazd and Shahed Universities. These systems enable us to take the multiple-choice and descriptive exams. In these systems, the exam questions are prepared by the instructor of the concerned lesson and placed in the system database. The students who have taken that lesson can be connected to the system from wherever they want. After entering their username and password they can take part in the exam. One of these systems has been created on the basis of the synchronous model and another one has been developed on the basis of the asynchronous model. Each of them has its own advantages and disadvantages. Also in this paper we have dealt with description of the Internet-based exam systems in two Canadian universities and finally we have proceeded to review the problems and troubles existing in taking Internet-based exams especially in Iran.
