Grades & Attendance
You may be interested in the distribution of course grades by class attendance (based on TurningPoint records) in PHYS 2212 G. The graph is showing that, for example, 64% of the students with "Good" attendance (greater than or equal to 90%) earned a A. The class GPA for students with Good attendance was 3.5. That for those with Fair attendance (60 to 90%) was 2.7, while that for those with Poor attendance (less than 60%) was 2.0. From another perspective, students with Good attendance were 51% of the class, yet they earned 67% of the A's. Student with Poor attendance were 14% of the class, but they earned 62% of the F's. Note that no student with Good attendance earned an F!
Students who attend class earn better grades
If you compare the above graph to the results for Fall 2004 through Spring 2008 posted at the beginning of the semester, you'll see that the trends are always the same! I'd like to thank those students who made the effort to attend class and participate.

Course Grades
Course Grades are available available in the Canvas PostEm tool. If you think your grade is erroneous, please contact Dr. Murray. On the other hand, if you just wish your grade were different, please do not contact Dr. Murray! Grades are determined by the same standards for all students, and all possible consideration has already been given.

Final Exam Grades
Final Exam grades are available available in the Canvas Gradebook. An adjustment was made to compensate for a difference in difficulty between the Regular and Conflict exams, so scores may exceed 100%. Exam forms will not be released through Gradescope, although if you stop by his office, Dr. Murray will be happy to go over your exam with you. Contact Dr. Murray to schedule an appointment, or if you have any questions.

Lab Averages
Final Lab Averages are available in the Canvas lecture Gradebook. Each student's poorest lab grade was dropped. If your lab grade seems surprisingly low, don't forget the penalty for excessive absences. Contact Dr. Murray if you think your posted Lab Average is in error.

Studio Averages
Final Studio Averages are available in the Canvas lecture Gradebook. Each student's poorest Studio grade (which may be an absence) was dropped. Contact Dr. Murray if you think your posted Studio Average is in error.

"Other" Points
"Other" Points have been calculated and are available in the Canvas Gradebook. Recall that "Other" consists of these items, the average for each of which is also in the Canvas Gradebook:

  Weight in Course
Regular Homework 5+2%
Practice Homework 4%
Class Participation 4%
Reading Questions 2%
Public Lectures 1 point
If you wish to verify the calculation,
  1. If your Regular Homework average exceeds 100% due to working it on a daily, rather than weekly, basis, temporarily treat it as 100%.
  2. Multiply each component of the "other" grade by the weight above (with Regular Homework at 5%). Note that the Public Lectures don't have a "weight". Add half a point if you watched one, add one point if you watched two or three.
  3. If the sum of those components exceeds 10 points, discard the excess
  4. If your Regular Homework average was 100% or less, this sum should match the value in the Canvas Gradebook.
  5. If your Regular Homework average was more than 100%, divide the excess by 0.20 and add it to the weighted sum. For example, if your Regular Homework average was 110%, the amount exceeding 100% is 10%, or 0.10. Then 0.10/0.20 = 0.5, so the value in the Canvas Gradebook should be 0.5 points greater than the weighted sum.
The greatest possible "other" score, therefore, is 12 out of 10. The average "other" score is 10.0! Dr. Murray would like to thank the students who put such serious effort into the course.
Contact Dr. Murray if you have any questions.

Public Lecture Points
Final points for Public Lectures (PL Points) are available in the Canvas Gradebook. A half-point was earned for watching one archived Public Lecture during the semester, one point was earned for watching two or more. Contact Dr. Murray if you think your posted Public Lecture Points are in error.

Homework Averages
Final Regular and Practice Homework averages, HW Regular Avg and HW Practice Avg, respectively, are available in the Canvas Gradebook. Contact Dr. Murray if you think your posted Homework Averages are in error.

Extra Credit
Extra credit for the Diagnostic and Concept Tests has been calculated and is available in the Canvas Gradebook as "XC Points". If you wish to verify the calculation, divide the sum of your points by 128 (each had 32 points, for a maximum total of 64, so dividing by 128 yields a value betwen zero and 0.5). Then add 0.25 for each one you earned a score greater than zero on. The resulting total, between zero and one point, will be added to your course average.

In-Class Averages
Final In-Class Averages, Class Participation (CP Avg) and Reading Question (RQ Avg), are available in the Canvas Gradebook. Contact Dr. Murray if you think your posted In-Class Averages are in error.
