Final Exam Location Change!!!
The final exam will be administered in Instructional Center 103. The announcement below has been edited to reflect this change. I apologize for any confusion this causes.
Apr 17
Final Exam Location and Format
The final exam period has been set by the Registrar's Office. The Final Exam for all PHYS 2212 sections will be administered Wednesday, May 1, 6:00–8:50pm in Instructional Center 103.
You may want to review the Exam Rules. Don't forget your photo ID.
The Final Exam will have four 13-point Free Response problems and sixteen 3-point Multiple-Choice questions. Some of the Multiple-Choice may require a bit more calculation than the Multiple-Choice did on the quizzes, but many will be strictly conceptual. I intend that topics in the course will be covered roughly evenly — that is, there will be no special emphasis on material after Quiz #4.
Remember that Quiz 5's from 2014 are available to help you prepare for material after Quiz #4.
Remember that calculators that cannot store text may be used on final exam. Note that if your calculator keypad includes a complete alphabet, that's a very good sign that it cannot be used. Do not expect to be provided with an appropriate calculator if you do not bring your own.
Remember the expectations for your work on the free response problems, which are the same good problem-solving practices you should be using on the homework, anyway.
  • Units should be shown with any value that has a unit
  • Algebraic manipulations should be performed with symbols, not values
  • Consider, but do not obsess over, significant figures
You may find an example helpful.
Please note:
  • Wednesday, May 1, 6:00–8:50pm. is NOT the usual period corresponding to your lecture time.
  • Except for conflicts with CS 1371, Physics will handle all other conflicts, even though standard policies might indicate otherwise
Students who notified Dr. Murray of a conflict will soon be contacted about alternative arrangements. If you have not yet checked the exam schedule for conflict with your other classes, please do so immediately and notify Dr. Murray by email if you have a conflict.

Quiz #4 Results
Results for Quiz #4 are available as a percent in the Canvas gradebook under Quiz #4.
The Gradescope link in the Canvas navigation menu will take you to Gradescope, where you will be able to see how you did on each Free Response problem and Multiple Choice question. Because the FR problems were graded as a percent, but the MC questions were graded as points, it was necessary to treat each student's quiz as if it were two quizzes in Gradescope, one with the FR problems and one with the MC questions. (The score posted in Canvas is your combined score.) Gradescope also shows you an internal code like ProbC (d) that I use to identify a particular question despite the fact that it has a different question number on different versions of the quiz.
The question about a charging and discharging a capacitor (ProbG) went very badly, and was converted to extra credit. If you wish to confirm your score in Cavas by your own calculation, find the points earned on each FR problem by multiplying the percentage score by the value (16 points), then add the points earned on all the MC questions other than ProbG. Divide the total by 0.92, then add any points earned on ProbG.
(Note that an error in the grade calculation was corrected at about 4pm on Friday afteroon. If you checked your grade before then, it may have changed.)
If you have questions or concerns about how your quiz was graded, you should contact Dr. Murray (the request regrade button in Gradescope is simplest, if that's your concern) before classes end on Tuesday, April 23.
Apr 12
Concept Test for Extra Credit
A Concept Test for extra credit will become available in Canvas at 11:59pm on Sunday, April 14. Note that it is timed—once you start it, you must finish in 60 minutes. The deadline for completion is 11:59pm Sunday, April 21.

Apr 03
Quiz #4
Quiz #4 will be administered on Tuesday, April 9, at 6:00pm in Howey L1. Do NOT go to the location listed in OSCAR. Do NOT go to the lecture location.
Remember:
  • Print your name, as it appears in Canvas, very neatly in the two separate Name boxes on the front page.
  • Write darkly and neatly. Blue or black ink is recommended. Do not make any erasures in your free-response work. Cross out anything you do not want evaluated. Box your answer.
  • Bubble your answers to the multiple-choice question on the front page.
  • The formula sheet is on the back of the front page. This page may be removed during the quiz if it makes things easier for you, but it must, of course, be submitted as it has your name and MC answers on it.
  • Initial the odd pages in the top margin, in case the pages of your quiz get separated after the staple is removed but before it is scanned.
  • If the page for a free-response problem has insuffcient space for your work, ask a proctor for an additional sheet. If you wish this work to be evaluated, put your name on the sheet and make a note on the problem page, so graders will know to look at the extra sheet for your work.
Remember that calculators that cannot store text may be used on the quizzes and final exam. Note that if your calculator keypad includes a complete alphabet, that's a very good sign that it cannot be used. Do not expect to be provided with an appropriate calculator if you do not bring your own.

PostEm
There's been an update to the PostEm Tool in Canvas. You should not notice any changes, but since we're piloting PostEm for the Institute, there may be unexpected effects. Please contact Dr. Murray if you run into any difficulties.
Mar 26
Final Exam Period
The final exam period has been set by the Registrar's Office. The Final Exam for all PHYS 2212 sections will be administered Wednesday, May 1, 6:00–8:50pm. A direct (Class I) conflict should be extremely unlikely, but it is possible to have three exams scheduled on the same day (a Class II conflict). Check the exam schedule for your other classes now, and contact Dr. Murray by email as soon as possible, but certainly by Friday, April 12, if you have a conflict. Please note:
  • Wednesday, May 1, 6:00–8:50pm. is NOT the usual period corresponding to your lecture time.
  • Except for conflicts with CS 1371, Physics will handle all other conflicts, even though standard policies might indicate otherwise
Final Exam format and locations will be announced as soon as they are determined.

Public Lecture Update
It has been brought to my attention that one of the Public Lectures conflicts with a quiz. I've removed it from the list, leaving us with: I don't want to put students in the inflexible position of needing to attend all the Public Lectures to earn the full "other" point, though. So, while you are certainly encouraged to attend both, that full point will be issued for attending either one.
Jan 31
Public Lecture Update
The first Public Lecture for other points is this Wednesday, February 6. The second Public Lecture now has a title. Credit will be based on attendance, recorded by TurningPoint. Full credit (one "other" point) will be issued for attending two or more Public Lectures. Half credit will be issued for attending exactly one.

PostEm Problem Resolved
The latest PostEm problem should be fixed, now, and homework grades from the first week should be available. Let me know if you still have difficulties.
Jan 16
PostEm Problem
New PostEm files (like the file of homework scores) aren't visible to students. OIT is investigating — something at their end changed between my posting erroneous homework scores Tuesday morning, and posting corrected homework scores this morning. I'll put another announcement here once the problem's been fixed.
Jan 15
Homework Scores
Scores for the first week's homework, including extra credit for doing the Regular homework early, are available in the Canvas PostEm Tool. Note that extra credit will only appear in scores posted on Canvas, never in MasteringPhysics. Contact Dr. Murray if anything doesn't look right.
OIT believes the widespread problem PostEm had over the weekend has been fixed. They're still working on a problem that they believe only affects students accessing Canvas from off-campus. In any case, if you run into any problems with PostEm, notice any oddities, or have any suggestions, please let Dr. Murray know.

Practice Class Participation Scores
Scores for questions polled in class during the first week are available under 01-09 and 01-11 in the Canvas PostEm Tool. Since the first week is for practice, these points don't matter. If you see a non-zero score, you know that your account is active and your answers are being received. If you believe you have activated your TurningPoint account and answered questions in class those days, but are seeing scores of zero, or no scores at all, contact Dr. Murray.
Note that we're piloting the PostEm Tool for Georgia Tech this semester — only one other course is using it. If you run into any problems with it, notice any oddities, or have any suggestions, please let Dr. Murray know.

Attendance
You may be interested in the distribution of course grades by class attendance in PHYS 2212 for more than 2500 students from Fall 2004, when the Knight text was adopted, through Spring 2008.

Students who attend class earn better grades

You should be aware that there is a wealth of historical data in the traditional introductory physics courses that clearly point out two winning strategies: go to class and do EXTRA homework. Please take some time to look over this data; you may be surprised at how much of a difference such efforts can make, popular myths to the contrary notwithstanding.

How to Earn an "A"
Students who earned a grade of "A" in some previous semesters were invited to provide suggestions for students this semester. If you want to know how they did it, and how (we hope) you can too, read their advice.
