The authors are currently in the midst of a substantial revision of Introduction to Chemical Engineering Thermodynamics, by Smith, Van Ness, and Abbott. This presentation will discuss the challenges involved in updating the style and content of a long-successful text without losing the essential character of the book or dramatically disrupting the practices and syllabi of current users. Changes that have been made, planned or considered will be presented, along with demonstrations of a variety of newly available online resources for instructors using the book. Key questions and issues include (1) how best to broaden the perspective of the text beyond the chemical process industry, (2) how to support flexible use of computer tools and a variety of software packages, (3) how, and to what extent, to incorporate molecular concepts, and (4) what changes in style or format may enhance pedagogy without compromising the character of the text. Most importantly, feedback on proposed changes, and further suggestions will be solicited.
