Final grades entered: We have entered the final grades into the
ISIS system after a spending a significant amount of time on setting grade
boundaries and handling several special cases. You should be able to see them
by Monday or so.
Determining grades for such a large class requires that we be consistent in
carrying out course policies, treat all students fairly and compassionately
and adhere as closely as possible to the grading criteria laid out at the
beginning of the semester. Our goal is always to establish a consistent and
predictable set of expectations (even among different TAs), while employing
policies (10% of points dropped) on all course work to allow students to recover
from bad days or missed work.
After analysis of all the grades, we decided not to change the grade
boundaries, except to accommodate students within a few hundredths of a point
of a boundary. Approximately 58% of the class has a grade of B or more,
higher than almost all previous semesters. We of course understand
that many people fell just below grade boundaries and there are inevitably
disappointments for people who worked hard and came up short. However, in a
class of 520 students, with grade differences between students typically
several hundredths to a a few tenths of
a point, this situation would occur wherever we set the boundaries.
We wish all of you well and hope that you have a good summer. We welcome
visits and would be glad to talk to you if you plan to take the course again.
Good luck, everyone!
Sincerely,
Paul Avery, Pradeep Kumar and Yoonseok Lee

Information was uploaded to WebAssign for exam totals (out of 70),
quizzes (out of 15), HITT (out of 5) and homework
(out of 10, chap. 16-25).
We also uploaded the total quiz points (out of 90) and
the adjustment per section that was
added to each student's quiz average (which was calculated by
dividing the total quiz points by 0.9 and scaling the result to 15 points)
to calculate the
quiz_final score. The adjustment can be negative or positive depending
on whether the section had an average higher or lower than 75% * 15 = 11.25.
The "quiz_final" score includes this adjustment.
We are still working on the grading scale.

28-Apr-2009 |
Exam solutions were posted on the solutions page early Tuesday morning. We are
still working on the makeup exams and the grading scale.
|
|
27-Apr-2009 |
Exam results are now posted to WebAssign. The average was 12.8, a pretty
good score. We are still waiting for the
results of the makeup exam to post the exam solutions. We plan to post
the solutions Monday night or early Tuesday morning.
We do not know the grading scale yet, but will post it Tuesday or Wednesday. Please
don't bombard us with mail because we just cannot answer yet.

CHANGE in Final exam reviews: Two reviews will be
conducted by Camila Mateo on Thursday,
April 23 from 5:00-7:00 and 7:00-9:00PM on Thursday April 23.
Both reviews
will take place in room 1002, next to the phy2054 lecture hall. The first review will cover
new material since exam 3 and the second review will cover the old
material through exam 3.
Tuesday's class will also include a review.
The 10 questions on the final covering material through exam 3 will
be taken from problems from the first three exams and the WebAssign
problems from those sections but modified somewhat.
All students are required to take the final exam. There is no truth to
the rumor that students with an A average are excused.

Midterm quiz grades
for section 3461 were uploaded today. Please read below to
see how they were calculated. |
|
3-Apr-2009 |
Midterm quiz grades: We have
uploaded midterm quiz grades to WebAssign based on quizzes 1-5 only.
The scores are out of 15.00 points max, where we dropped 10% of the
points. To see your score, log into WebAssign, click on My Assignments,
then All Assignments and find the score for Midterm_quiz. We also
posted Midterm_Q, the raw sum Q of quizzes 1-5, described in the next
paragraph.
The formula is as follows: Let Q be the sum of
quizzes (each out of 10, so Q is 50 or smaller). Then the quiz grade =
1.5 * (Adj + Q/5/0.9), where Adj is the adjustment for each section,
discussed below. 1.5 converts from a 10 point scale to a 15 point scale.
(For section 3461, which did not have quiz 1
because of a missing TA early in the semester, the grades will be based
on 4 quizzes. Thus the formula is 1.5 * (Adj + Q/4/0.9), where Q is 40
or smaller. However, we have not posted your scores because we are
still awaiting a quiz grade from your TA.)
We normalized each section so that the average for
the section is 75%, so section scores either went up or went down
(though no section went down by more than 0.85 pt).
These are approximate grades.
We will recalculate the section adjustments at the end of the semester.
Since our calculation of Q uses the scores that your TA provided to us,
please talk to your TA if you have a question about your quiz grades.
|

2-Apr-2009 |
Midterm quiz grades:
We are still working on these grades. It turns out to be much a more
challenging programming problem (many kinds of special cases) than we
had initially thought. We will try to get them by Saturday. |
|
31-Mar-2009 |
Comment about midterm grades:
The midterm_exam grade that we posted was obtained by scaling your exam
points (out of 40) to 70 points (after dividing by 0.9). It is simply
an extrapolation of your current progress to the
entire course. After you take all four exams (worth 90 points), the
score is calculated as shown on the grading page (scaled to 70 points).
The grading page now has an example to illustrate the calculation.
Grading scale: We cannot answer
questions about the grading scale until the end of the semester. We
expect that grade boundaries will go down a couple of points but we can
offer no predictions at this time.
Prof. Avery will be away Apr.
1-10 on two back-to-back trips. Please see Dr. Kumar if you need to
discuss grades.

Exam 3 review: Camila Mateo
will hold the exam 3 review Tuesday, March 24 in room 1001 (our
classroom) from 6:15 - 8:15.
We have created a formula page
summarizing the formulas in chapters 15-22. We will continue to update
this file as the semester progresses. Please let us know if there are
any mistakes or anything missing.

20-Mar-2009 |
Midterm scores uploaded to WebAssign:
Approximate scores were uploaded to WebAssign for exams, HITT and
WebAssign homework. Quizzes will be uploaded next week when we get all
the scores.
Midterm exam is calculated by
scaling your two exam scores (after dropping 10%) to 70 points. The
formula is
70*(exam1+exam2)/0.9/40. The maximum is 70. If you are taking a makeup
for one of the exams, then that exam counts as a 0 for now since we
have no other information. You can make an estimate for that exam and
use the formula to approximate your exam total.
Midterm HITT is calculated by
scaling your raw HITT points through March 20 to 5 points after
dropping 10%. The formula is
5.0 * (points/0.9/MAX), where MAX=57 for period 4 and MAX=58 for period
5. The maximum is 5.00. If your HITT score is zero it means you have
not registered your remote on the course registration page.
Midterm WebAssign is calculated
by scaling your raw WebAssign points (70 points total) for chapters
16-20 to 10 points after dropping 10%. The formula is 10.0 *
(points/0.9/70). The maximum is 10.00.
Midterm quizzes cannot be
calculated yet because we are waiting for scores by the TAs. These will
be uploaded next week. The quiz average for each TA will be normalized
to 11.25/15 (75%), so you can estimate your quiz grade based on how
well you think you are doing relative to the average.
Grade scale: Looking at the
grades we have so far (no quizzes), we expect that the grade boundaries
will go down by 4-5 points for the B+ and below grades. We will post an
approximate set of boundaries next week once we get the quizzes.
Please don't bombard us with email about the
calculation or the grade boundaries. We will of course update this page
if the procedure is not clear.

Quiz 7 has been moved to the
week of March 30 to avoid being given the same week as exam 3.
Chapter 21 notes were reposted
with additional slides that explain reactance in more detail and derive
expressions for phase angle, XL XC, impedance, resonance and the
connection between RMS quantities and average power in AC circuits.
|
|
17-Mar-2009 |
Midterm grades: We are still
working on the calculation of the mid-term grade, but have been
hampered by some missing quiz data (most of the TAs are attending the
March APS meeting). We will get this information as soon as we have it
and post the mid-term numbers on WebAssign ASAP. This grade will
include all work up to Spring break, including the 10% dropped points
on all components so that you can get a realistic picture of how you
are doing.
Grade boundaries are expected
to be adjusted downwards. We will make an estimate when we post the
mid-term grades.
WebAssign homework for Chap. 20
is due Wednesday night, Mar. 18.

URGENT: EXAM 2 DATE CHANGE: We
just learned that the rooms we requested for exam 2 were given to us
for Thursday, March 5 instead of
Wednesday, March 4. Please make a note of this new
date. We will send a note to everyone through
E-Learning as well as by ordinary email. We are also posting
announcements in E-Learning and WebAssign.
We are aware that many people are taking the
Biochem exam and need time to get to the exam. To compensate, we will
give the exam 5 minutes late and allow an extra 20 minutes, bringing
the finish time to approximately 10:45. This should provide plenty of
time for you to get to your assigned room and finish your exam without
time pressure. Thanks to those of you who brought this issue to our

Exam 1 adjustment: We have
decided to adjust the grade of exam 1 upward by 1 point, partly because
it is a first exam and partly yo reflect the difficulty of the exam.
The new scores have been posted on WebAssign as "Exam 1 new". The new
average is 11.5, and the adjusted distribution has been posted on the solutions page.
This would be a good time to reread the "Effective
strategies for learning physics" section on the overview page. The section
discusses the strategies for success that we typically see in the B+
and A student whom we have interviewed.
After exam 2, we will post a "midterm grade",
which includes all work up to that point, including the 10% dropped
points on all components so that you can get a realistic picture of how
you are doing.
Tea & Cookies Tuesday:
Prof. Avery will be conducting it from @ 5:00 till no later than 6:30

in room 100 New Engineering Bldg.
Chapter 15 homework solutions
are posted in the E-Learning area under pdf files.

25-Jan-2009 |
New SI hours:
Camila has informed us that she has modified her hours at Supplemental
Instruction. She also tutors 4 hours per week at Broward Hall. The new
information is on the seeking
help/office hours page. |
|
16-Jan-2009 |
WebAssign extension: Because of
the recent problems with WebAssign and the textbook, we have extended
the Chapter 15 homework to Jan. 21, Wednesday, 11:59PM. WebAssign has
graciously extended the free period until Jan. 24. This is our version
of a physics stimulus plan. :-)
We fixed an error with the date in the preceding
paragraph. It is Wednesday, Jan. 21, not Jan. 22.
WebAssign has also fixed the display problem for
Chap. 15 for IE7. Let us know if you encounter other problems.
|
|
15-Jan-2009 |
Browser problems on WebAssign:
It appears that Internet Explorer 7 has display problems with some of
the problems in Chap. 15. We are investigating this problem with the
WebAssign people. In the meantime, please use another browser such as Firefox which seems
to work perfectly.
In the meantime, because of this problem and the
textbook availability problem, we have requested WebAssign to extend
the free period a few more days. Please watch this space for more news.
|

13-Jan-2009 |
Textbooks have arrived! This is
according to one of the management people at the UF bookstore.
SI instruction hours: The
original posted hours for SI have now been corrected. The periods were
correct but the times were wrong. We're very sorry for the
misunderstanding, which arose from an incorrect assignment of times to
particular periods. Please see the seeking
help/office hour for the correct information.

12-Jan-2009 |
SI instruction hours:
One of you noticed that the periods and times for SI are inconsistent.
We are checking to see which is correct and will correct the posted
information ASAP. |

10-Jan-2009 |
PDF files from textbook: We
were (finally) able to get access to an electronic version of the
textbook and make pdf files of Chapter 15 and 16. The pdf files are
low-resolution images of each page, rather than true text, but they are
quite readable. Note that the files are from the 8th edition, not the
7th edition, since that was all that was available.
(Added Jan. 12. We finally received the 7th
edition file for Chapter 15. It is posted at E-Learning)
The files are available under phy2054 in
e-Learning, which you can access at https://lss.at.ufl.edu/.
Since the files are so large (about 18 MB), we posted them in two
versions, one uncompressed and one compressed. The compressed files are
about 1/2 the size of the uncompressed files and look almost identical,
so you will probably just want to get the compressed versions.
Prof. Avery is traveling to
Washington, DC and will not return until Jan. 22. He will do extra
office hours when he returns.

09-Jan-2009 |
Textbook: We are working to
resolve the problem with the textbook at the UF bookstore. For some
reason the publisher held back the book shipment without informing the
bookstore, causing confusion and delays. They should be arriving early
next week, though not positive the exact day. In the meantime, we have
requested them to send us Chapter 15 in pdf format so that we can post
it for you. Even that process is taking far too much time. Please check
this space for updates.
We are using the 7th edition. We are aware that
some of you bought your text at the Orange and Brew bookstore, which
sold the 8th edition. That book will work, but the chapter problems are
in a different order.
Online resources: We will
cover E fields and Gauss' law on Tuesday. Even without the text you can
find material online. For example, the Physics Classroom
has a variety of lectures and demos aimed at the advanced high school
level, including tutorials
and animations.
There is also a simple
applet showing an electric field as well as a more advanced applet
that shows much more (multiple charges). FInally, this cool electrostatics
applet shows charged points, dipoles, lines, etc.
HITT: We will begin using
HITT for points on Tuesday. Register for HITT now.
WebAssign: Only 119 students
have registered in WebAssign. Please be aware that the first assignment
is due Jan. 18 and there are no extensions.
|

08-Jan-2009 |
Supplementary Instruction location:
Our SI instructor managed to get Physics 1100 for the three SI
sessions. Please see the seeking
help/office hour page for additional information.
Hardcopy of sample exams:
Target Copy has received the order and will sell the sample exams for
$19.99. They are expected to be ready by the end of today, Jan. 8. Note
that some of the exams are different than the ones posted online (the
online ones tend to me more recent).
WebAssign: Only 80 students
have registered in
WebAssign. Please do so today and Friday because we need to know if
there are any more problems (e.g., passwords not working). Remember
that the first assignment is due Jan. 18 and there are no extensions.
We added 15 new students this morning to WebAssign.
HITT: Please register your
transmitter using the link on the registration
page. We will do some tests during today's lecture.
Exam dates are final.

07-Jan-2009 |
Review books: At the suggestion
of one of the students, we added the College Physics review book to the
list of review books on the Overview
and References
pages. This book has a lot of good material and many problems at the
PHY2054 level.
Textbooks: The UF bookstore did
not have textbooks late this morning but might have taken delivery this
afternoon (the Jan. 12 date on the shelf is apparently a placeholder
date). We will check on this situation Thursday morning and determine
which other locations are carrying books now.
E-Learning: We registered the
course in the E-Learning system this evening, but only did so to see
what capabilities might be useful. We plan to upload grades to
WebAssign, but might try to upload them to E-Learning as well if the
process is not too complicated. Perhaps some of you could let us know
the advantages of using the E-Learning tools?

06-Jan-2009 |
WebAssign is ready: Students
have been uploaded to WebAssign (1:45PM). If you used WebAssign in a
previous semester, your password is not affected. If you have been
added for the first time (using your 8 digit UFID), the password is
your UFID. Please change it when you first login to WebAssign.
Supplementary Instruction: We
have tentatively set up the schedule on the seeking help/office hour page.
We have 3 times that occur at different parts of the course schedule.
However, the rooms have not been assigned yet. Stay tuned.
Tea and Cookies: We will have
our first session today at 5:15PM for students who feel like showing up.

Welcome to PHY2054! This is a
new web site, so material is still being added in several places. We
welcome comments and suggestions for making this course web site a
unique resource for students. In particular, we would appreciate links
to online material (explanations, problems and solutions, interesting
applications, applets) that could enhance learning.
Texbook (Serway &
Faugn, 7th edition) is bundled with WebAssign. Be aware that WebAssign
must be purchased separately online if you buy the book used.
WebAssign: We have set up the
first assignment (Chapter 15) on WebAssign that you can work on now.
Exam schedule is not fixed yet!
We are still working on the dates, which we hope to be fixed this week.
Do not make plans around the current dates.
Contacting us by email: If you
contact us, always send mail to phy2054 AT phys.ufl.edu and include a
meaningful subject line. Do not send mail to our individual email
accounts.
Discussion sections begin Wednesday,
Jan. 7.
