Homework in CHE 232

Online Homework (ACE Organic)

In collaboration with some UK computer scientists and the publisher Pearson Education, I have developed a Web-based organic chemistry homework program called ACE Organic. This program asks you to draw organic structures in response to a question. If your answer is incorrect, you are given some feedback, but you are not told the correct answer. You need to keep trying until you get the right answer.

Your performance on the electronic homework problems (percentage of problems answered correctly, excluding the tutorials) will contribute to your overall grade. (See the syllabus for the proportion the homework contributes.) You will be allowed an infinite number of tries to answer most questions, so there is no reason any student cannot score 100% on the electronic homework. Feel free to ask for help from me on any problems. You may also use the course forum to post questions about the homework or to help other people with their problems.

ACE gives you the ability to grant yourself extensions on the homework. Here are the rules:

• You start the semester with a maximum amount of extension time that you can grant yourself across the course, e.g., 20 days.
• Any particular assignment, and especially one that is due right before an exam, may limit the length of an extension on that assignment.
• You may only grant yourself an extension on an assignment before the assignment is due.
• You may change (increase or decrease) an extension that you have already granted yourself, as long as the original due date and time has not passed.
• Within these limits, you may grant yourself any length of extension (e.g., 1.5 days) on an assignment. Use your allocation wisely!
• Under unusual circumstances (such as illness, a family emergency, or an avalanche of work in other courses), you may ask your instructor (by email) to grant you an extension on an assignment that is greater than the one you are permitted to grant to yourself. Any such extension counts against your total allocation.
• Under very exceptional circumstances, you may ask your instructor (by email) to grant you an extension on an assignment even if you have already exhausted your total allocation.
