Old Announcements

[3 May]
All students' final total scores for Reading Quizzes, ConcepTests, Recitation Quizzes, Labs, Exams 1 & 2 & 3, Excused Exams, and Final Exams and Final Grades have been posted in our glass case (located on the first floor of the Chem.-Phys. Bldg. near the stairs by the entrance to the building from the parking lot).

The average on Final Exam A was 127.6 and on Final Exam B was 135.9, out of 200 possible points.    [Solutions are here.]

Note: Final renormalized scores (labeled “Normd”) have been rescaled from raw point totals according to the maximum values specified in the final grading scheme. The renormalized scores are the ones that are added to get the TOTAL Score shown. Your 3 lowest Recitation Quiz scores have been dropped, as promised, for a maximum possible 105 Recitation points, rescaled to 200 points. The maximum total equals 1000 points.

The average of everyone's Total score (out of 1000 points) is 756 points in Lecture A (§§ 1, 3, 5, 7) and 758 points in Lecture B (§§ 4, 6, 8).

If you have any questions about any components of your scores, please contact the Instructor.

Scores have been readjusted (columns labeled “Normd”), to reflect the relative weights to be used in the final grading scheme.
Posted scores are accompanied with pretend “Grades” which are, however, meant only to serve as temporary guideposts; they do not necessarily reflect final grade cuts!
The average of everyone's Total score (out of 800 points) is 631.8 or 79.0% in Lecture A (§§ 1, 3, 5, 7) and 621.7 or 77.7% in Lecture B (§§ 4, 6, 8).

Course evaluations are an important (and mandatory!) component of our Department's instructional program. An online course evaluation system was developed to allow each student ample time to evaluate each component of the course and instructor, thus providing the Department with meaningful numerical scores and detailed commentary while minimizing the loss of instructional time in the classroom.
Please help us out by giving us your feedback. The evaluation window for Spring 2002 will open tomorrow—on 9 April 2002—and close on Wednesday, 24 April, 2002.
To access the system during this time, simply go the Department of Physics & Astronomy Web page and click on the link for Course Evaluations; then follow the instructions. You will need to use your student ID# to login to the system, and this will also allow us to monitor who has filled out the evaluation. However, when you login you will be assigned a random number that will keep all your comments and scores completely anonymous.
Thanks!!
