In-class Activities Many class meetings will have some type of in-class activity. Among the different types of activities will be short quizzes, worksheets out of Lecture Tutorials for Introductory Astronomy, five-minute essays, multiple choice Colored Card questions, ranking tasks and comment cards. Days which have activities will be chosen at random. The Lecture- tutorial workbook will be collected at each exam and graded for completeness. The workbook will count for 2/3 the in- class grade (that’s 10% of your total grade!). IF YOU HAVE A USED WORKBOOK, TAKE IT BACK AND GET A NEW ONE! YOU WILL NOT RECEIVE ANY CREDIT FOR WORK DONE IN A USED WORKBOOK!* *If your “used” workbook has no writing at all in it, bring it to me and I will approve it for use. If it is not approved by me before you turn it in you will not receive any credit for it.

Homework Homework will be assigned by chapter and will be due on the day of the first class meeting following the completion of a chapter. Most of the homework will be done online using the SmartWork system run by the textbook publisher. There may also be exercises handed out in class which will be due at the beginning of the next class meeting.

Why we will be doing stuff other than lecture in class From How People Learn: “Students enter your lecture hall with preconceptions about how the world works. If their initial understanding is not engaged, they may fail to grasp the new concepts and information that are taught, or they may learn them for the purposes of a test but revert to their preconceptions outside the classroom” How People Learn, National Research Council, National Academy Press, 2000

Active Learning Active learning is when students take active responsibility for participating in and monitoring of their own learning by engaging in critical reasoning about the ideas presented in the class. In other words: you must do it, you won’t learn it if I just tell it to you
