Abstract This paper describes the development of Internet-based unit operations laboratories illustrating membrane processes: dialysis and nitrogen production from air. Potential software and hardware approaches to remote experimentation are summarized. The implementation of each experiment in a Windows 2000 environment is presented – detailed equipment lists and costs are provided.

Several options for providing video and audio signals were evaluated including: (1) RealNetworks streaming media, (2) NetMeeting, (3) Polycom ViewStation FX, and (4) Polycom ViaVideo Desktop System. Each offers different combinations of video quality, latency, and cost. The impact of the video/audio signal on the educational effectiveness of the experiment is discussed.

Preliminary evaluations of the learning effectiveness of these experiments are presented. Learning, attitudes, and collaboration of students who completed the dialysis experiment were assessed through focus groups. The results will be used to guide future evaluations of the experiments. Assessment focused on the following specific issues: (1) student motivation (student interest in achieving learning objectives, enjoyment of the laboratory exercise, and personal interest in the content), (2) level of student comfort with performing an experiment through the Internet, (3) degree to which students perceive the experiment as authentic, and (4) the extent of collaboration between students and between students and the instructors.

Motivation Internet-delivered Unit Operations Laboratory experiments (real-experiments run in real-time) could have a profound effect on education. Such experiments could provide access to modern, relevant experiments in Chemical Engineering areas that would not be available otherwise due to lack of funding, time, or expertise. Moreover, departments would not have to maintain as many experiments which would free funding for developing new experiments or updating existing ones.

Internet delivery could increase access to modern experiments while simultaneously saving money.
