Graded homework assignments are administered using the Sapling Learning online homework system (go here for information on how to get started with Sapling). Due dates are listed at the bottom of this page.

Our Sapling system also provides ungraded practice problems. Please make sure you understand the different expectations for graded and ungraded work.

  • Short graded assignments (approx. 4-10 problems) have been created for each day of class. These assignments are usually posted right after TuTh class meets and are available for approx. 10 days (see calendar at bottom of page). If you are unable to access or attempt an assignment for some reason, contact Alan to see what can be done to fix the problem and/or arrange an extension.
  • A much larger set of ungraded practice problems (approx. 20-30) have also been created for each day of class. These assignments can be worked at any time during the semester (Aug 31-Dec 17). It doesn’t matter which set of problems, the graded ones or the ungraded ones, you try first.

Note: While there are some advantages to online practice (instant feedback, multiple attempts), it is also important to develop good drawing skills. Neuroscientists have discovered that time spent drawing and handwriting not only enhances your ability to draw quickly and clearly, it might also help you remember chemical information and relationships. To get drawing practice, either draw your Sapling answers on a pad before you enter them online, or combine Sapling practice with additional practice with end-of-chapter problems in your textbook.
