COMMENT ON GRADING CHANGE
Fri 08May2009 3:37PMWe have been informed that there were inappropriate actions during the in-class clicker quizzes. Students were passing down answers between classes and others were having scores registered even though they were not in class. To minimize any distortion that this introduced the following changes were made, after discussions in the Physics Department, in scoring for the course. The number of points allotted to Clicker quizzes was reduced from 100 to 50 points. The points total was reduced from 1000 to 950. There was also a lowering of points needed for each letter grade category.

Wed 29Apr2009 1:45PMThe final is at 1:00 - 3:00 PM May 6 in Stewart 189 (Loeb Theater). We will have to use both the lower theater and the balcony. To facillitate the start those students who went to room EE 129 for test 1 & 2 should fit in the balcony and should go there to begin with as their lab Innstructors will be there.. We will have to shift a few latecomers but it is all one site. There is a second group scheduled for 3:20 Pm so we will have to finish up on time.

Unfair clicker quiz practices
Wed 11Mar2009 1:41PMI have received complaints from some 221 students that some other students are using practices in the clicker quizzes that are unfair to them. The two practices are:
1) getting correct answers from the 8:30 class and using them in the 9:30 class
2) students using several clickers so that others not even taking the exam are getting full credit.
To reduce the unfair advantage 1) I will scramble questions and in the future use different questions in each class. To reduce unfair advantage 2) there is now a clear policy of ONE AND ONLY ONE CLICKER PER STUDENT. A staff member will be present at lecture and enforce this rule.
