With the every growing costs of running a Chemistry laboratory and the ever-changing needs of today's studenis a logical alternative seems to be a computer based instructional format. When delivering courseware via the Internet, the greatest problem comes in making the interface and applications user-friendly and not jusi attractive. In order to test the utility of such a site, subjects are recruited and asked to evaluate the system. Their responses are essential in designing and improving the program to best meet the needs of students. In order to address student concerns, a Help Page was developed which clarified areas and sequences of steps that students found confusing. A major component of the multimedia system developed in this project is the Pre-Lab Quiz which consists of both numerical and multiple choice questions. Concepts involved in solving multistep problenis are structured so that an intelligent tutoring system could also be implemented. A randomization scheme for the input data in the numerical questions is developed and this insures that the prelab quiz is unique for each student.
