Abstract

Strategies for designing effective multimedia educational materials for lessons that are delivered over the Internet will be illustrated using lessons developed for the sophomore-level chemical engineering course on material and energy balances. The advantages offered by the Internet may be exploited to create a valuable educational experience for the student that cannot be duplicated in the formal classroom. These advantages include: i) convenient access to the course from any location and on any schedule; ii) an added level of communication of the scientific concepts through well-designed audio-visual content (including voice, simulations, animations, pictures, and video); iii) the students’ control of the pace of the course; and iv) the ability to easily integrate problem solving with the “lecture” component of each lesson. We have developed an Internet version of CHE 201: Material and Energy Balances that illustrates some of the potential for delivering college courses over the Internet. Features of this course include: i) hour-long lessons that are delivered using voice, text, pictures, simulations and animations; ii) sets of 10 to 20 short answer questions that the students encounter about every 20 minutes and are designed to reinforce the concepts that they just learned; iii) an electronic bulletin board (called the WebTalk discussion system) that everyone can access which includes student questions that are updated and answered daily; iv) weekly homework assignments (with posted solutions), and quizzes as well as regular exams that are administered by an approved proctor; v) a cooperative group project in which teams of students work together over the Internet; and vi) a hypertext glossary that can be accessed by clicking on the word to be defined or by moving to the glossary web page.
