Quiz #5 from 2014
Although no old final exams are available for practice, in the past there were five quizzes in the course, and the very last topic was something we no longer cover, AC circuits. The result is that old Quiz #5's are largely on the topics that now appear only on the final exam. Here are two of the last Quiz #5's, one in my style and one in Dr. Jarrio's, with the same disclaimer as the other old quizzes:
Students wishing to practice for an upcoming quiz are invited to review the following materials, which consist of actual quizzes and/or solutions from previous semesters. Be warned that that the topics on one of these old quizzes may not correspond exactly with the topics on this semester's quiz of the same number. You should also not make the mistake of assuming that these are practice quizzes for this term–the appearance (or absence) of a particular type of problem in the quizzes listed here should not be indicative of the only types of problems you might see on this term's quizzes! It is up to you to make intelligent use of this information.

Final Exam Location and Format
The final exam period has been set by the Registrar's Office. The Final Exam will be administered on administered Wednesday, December 12, 6:00–8:50pm. Students should go to the following rooms, which are NOT NECESSARILY the same as for the quizzes. If any student goes to the wrong room, it is likely that there will be insufficient seats and/or exam forms in that room! You may want to review the Quiz 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 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, December 12, 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 Score.
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 that I use to identify a particular question despite the fact that it has a different question number on different versions of the quiz.
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) before the Final Exam is administered on Wednesday, December 12.
Nov 19
Concept Test for Extra Credit
A Concept Test for extra credit will become available in Canvas at 11:59pm on Sunday, November 25. Note that it is timed—once you start it, you must finish in 60 minutes. The deadline for completion is 11:59pm Sunday, December 2.

Final Exam Locations
The Final Exam will be administered on administered Wednesday, December 12, 6:00–8:50pm. Students should go to the following rooms, which are NOT NECESSARILY the same as for the quizzes. If any student goes to the wrong room, it is likely that there will be insufficient seats and/or exam forms in that room! Remember that
  • Wednesday, December 12, 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.
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 in you have a conflict.
The Final Exam format will be announced as soon as it is determined.
Nov 15
Final Public Lecture
The probably Public Lecture did not materialize. One Public Lecture for other points remains. Credit will be based on attendance, recorded by TurningPoint. The channel and sessionID will be written on the board at the start of lecture. Submit any response to a question that will be opened about 10 minutes into the talk. If the room is full, there will be overflow into Clough 144 but you will need to head back to 152 after the talk to submit a clicker answer. If something goes wrong with the clicker system, don't panic, look for Dr. Greco after the talk to sort it out.

Quiz #4
Quiz #4 will be administered on Tuesday, Nov 13, at 6:00pm. Students should go to the following rooms, which are the same as for the previous quizzes. Do NOT go to the location listed in OSCAR (unless, of course, it just happens to match the location below). If any student goes to the wrong room, it is likely that there will be insufficient seats and/or quiz forms in that room! You may want to review the Quiz Rules. Don't forget your photo ID.
Your quizzes will scanned into Gradescope for grading. To make this go more smoothly:
  • 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 where to find 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.

Quiz #3 Results Corrected
ProbH was incorrectly graded on Version D. Corrected scores were posted at about 2pm. I apologize for my error.

Quiz #3 Results
Results for Quiz #3 are available as a percent in the Canvas gradebook under Quiz #3 Score.
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 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 capacitor with a dielectric (ProbH) 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 ProbH. Divide the total by 0.92, then add any points earned on ProbH.
If you have questions or concerns about how your quiz was graded, you should see Dr. Murray before Quiz #4 is administered on Tuesday, Nov 13.

Volunteer Eco Students Abroad
I prevented the VESA people from making an announcement in class, by promising to post a flyer if they sent one. Instead, they sent me an email, asking me to forward it to everyone. I wasn't about to do that, because I want you to know if you get an email from me, it's because I think it's very, very, important. So I've posted the information in their email here. Note that the informational meetings are tomorrow, Thursday, Oct 25.

The layout of this quiz will be a little different from Quiz #1. I hope that making the form more Gradescope-friendly will enable us to get results to you more promptly. An example of what Quiz #1 would have looked like in this format is available. In particular:
  • 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.

First Day:

Cover of Text Text
An e-text of Physics for Scientists and Engineers — A Strategic Approach (Fourth Edition) by Randall D. Knight will be provided with MasteringPhysics. If you wish to purchase a hard copy,

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.
