In this paper, a novel website is described that provides interactive learning for undergraduate process control. The site engages the students through a set of questions that follow the topic sequence in a standard course. The questions begin with simple, yet essential, terminology and definitions, and then move on to engineering applications. Students can request hints for many questions, and they receive feedback for correct and incorrect answers. The software enables students to learn on their own schedule and at their own pace. Suggestions are provided to enable the instructor to complement this computer tool with guidance on self-study learning skills. Those interested can visit the site, http://www.pc-education.mcmaster.ca, which is open for instructors and students interested in process control.
