1. ChemAxon products role in ACE Organic, a Web- based organic chemistry homework program Robert B.

2. Why a Web-Based Organic Chemistry Homework Program? Textbook publishers provide solutions manuals Knowing the answer knowing how to answer Logistics of paper-based homework

3. Why Not use an Existing Homework Program? Most require text, numerical, or multiple-choice input, not chemical structures (exceptions: OWL, ChemCoach) Most do not provide feedback that is tailored to a students erroneous reasoning (exception: Quantum Tutors) Dont permit instructors to modify or add to database of questions In other words, not suited for organic chemistry!

4. Key Features of ACE Students draw structures in response to questions ACE provides response-specific feedback but withholds the answer Database of >1600 questions, each with feedback for many different kinds of responses Instructors may author questions or edit existing ones Greater coverage of certain topics desired Error discovered in database question Unanticipated incorrect responses that warrant specific feedback not already provided Grades & students final responses automatically recorded May be used with any textbook
