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

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 student’s erroneous reasoning (exception: Quantum Tutors)

• Don’t permit instructors to modify or add to database of questions

In other words, not suited for organic chemistry!

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
