WebAssign is your online homework system
WebAssign will run concurrently with the lecture topics. When you open an assignment, the questions you see will be from parts of the book that you have NOT discussed in lecture or discussion. This is to emphasize the value of working ahead in your textbook and attempting problems that you might not have been ‘lectured on’; the hope being that this will
- encourage you to come to lecture well prepared and with thoughtful questions, and
- demonstrate that the act of working through new information is an integral part of the learning process.
You should expect to see an assignment roll out on Wednesday and be due the next Tuesday or Wednesday. We anticipate that these homework assignments will be approximately one or two hours of work for you for the week, which will allow you to get credit for your working the ‘end-of-chapter problems’. Additionally, some questions will come from sources other than Laird, and will supplement your problem-solving skills. Shorter, more regular assignments should make it easier for you to plan your work.
Guidance on working with WebAssign
The number of tries is two per question. We will continue to allow two submissions per question, except when the question is multiple choice, in which case it will get one submission allowance.
We may, from time to time, increase or decrease the number of attempts for particular questions.
Note that WA, being a computer program, only knows to tell you ONE part of your incorrect answer. E.g., if the answer is -13.2, and you put 12, it will tell you "your answer is of the wrong sign," but NOT that you are numerically wrong. Our advice is to re-evaluate every answer, using the info WA gives yu, but don't assume it's the whole story.
WebAssign is intended to be a low-pressure environment. To that end, we strongly encourage you to use the "practice" problems for the questions to hone your skills before submitting an answer to be graded. Many of you have been using this functionality to great effect already! If you do so, submitting your answers should return to the low-risk, low-pressure format we intend WA to be. It's a tool that is going to pay off on your exams.
