What determines your grade:
 three exams (16% each)
 laboratory reports (25%)
 final exam (27%)
 homework is not graded
Curve:
What it is:
 WebCT is a website with passwordprotected login.
 For this course it will be used for the limited purposes of allowing
you to:
 view your grades during the semester
 view homework solutions
 vote for which HW problems you wish to see reviewed
in class
How to use it:
 Log on using My
WebCT
 The login ID for each new account will be the student's HawkID.
If you don't know your HawkID you can find out what it is by calling
the Customer Information Desk (3840800), looking it up in WebISIS (http://isis.uiowa.edu/)
or calling the ITS Help Desk (3844357). The initial password for any
new WebCT accounts will be the student's University ID number. Students
who already have a WebCT v3 account should use their existing user ID.
Note that the student's WebCT v2 ID's won't work in WebCT v3.
 If you have problems using WebCT, call the ITS Help Desk (3844357).
How many:
 three onehour exams
 a final exam
What they're like:
 All exams are multiple choice and closed book.
 The onehour exams will each have approximately 15 multiple choice
questions; some questions will be conceptual (or reasoning) and others
will require calculation.
 Each exam includes one question based on the labs. Example: "In
the Coulomb's Law experiment, after adjusting the zero for the torsionwire
balance, you apply a charge to both spheres and you find that the balance
turns by 20 degrees; by how many degrees would you expect it to turn
if you doubled the separation between the spheres?"
 A seating chart, showing which seats in the room you may use, will
be displayed on the projector screen before the exam begins.
What to bring:
 Bring a pencil, an eraser, and a calculator. See Policy
on calculators.
 With the exam paper, you will be provided a standard page of formulas.
 No other notes, materials, or electronic devices are permitted.
The most effective way to study:
 Before you do homework problems:
 read the book before the lecture
 attend the lecture
 review your lecture notes the same day as the lecture
 work through example problems
 Then do the homework
 After you do the homework, review:
 your completed homework
 notes
 text
 lab manual
Make up exams:
 Makeup exams will only be given for verifiable medical reasons or
for absence due to official University activities.
 It is up to you to inform me by email as soon as possible if you will
be missing an exam.
Honesty:
 Efforts are made to prevent and detect cheating on exams.
 In case of cheating, the instructor will assign a zero for the exam
grade and recommend to the Associate Dean that the offender should be
placed on academic probation, if it is their first offense.
The role of homework:
 Homework is the central part of your learning experience, outside
the lab.
 The lecture helps prepare you to do the homework, and the exams test
what you learned while doing the homework.
 Homework is neither collected nor graded; nevertheless, if you wish
to perform well in the course, you must do it.
Solutions:
 You may see the solutions to the homework on WebCT, after the date
shown on the schedule.
Help with homework:
 You may seek help in doing the homework from anybody you wish, including:
 Your TA, during office hours or after lab
 TA's in the Tutorial Room
 Prof. Goree during office hours or by appointment
The role of the lab:
 Because physics is an experimental science, the laboratory is a critical
part of your learning experience in this course.
Who teaches the lab:
 Lab sessions are conducted by a teaching assistant
under the supervision of Prof. Goree and the department's Lab Coordinator.
All students must take the lab:
 Students who have already taken the course from another instructor,
like all other students, must take the lab. This is because Prof. Goree
is beginning a new practice of integrating the labs into the course,
using more labs, and covering them in the exams.
Before the lab:
 Read the lab manual
 Complete the prelab report
When your papers are due:
 Prelab reports are due at the beginning of each laboratory
period.
 Worksheets are due at the end of the laboratory period.
If you miss a lab:
 You may elect to not makeup one lab that you miss; you are required
to complete 12 of the 13 labs to pass the course.
 You may do the makeup lab during the last week of the semester.
 Making up a lab by attending another section is discouraged. According
to departmental policy: only if all three of the following conditions
are satisfied will you be allowed to make up a lab by attending another
section:
 You must get approval, one week in advance, from both your TA
and the TA of the lab section you wish to sit in on; and
 The lab section you wish to sit in on is not full; and
 The lab section you wish to sit in on does not have other
"visitors" that day.

You may vote, using
WebCT, for the HW problems you wish to see solved in the "HW
review" lecture preceding the exams. To do this, post a message
on the "bulletin board" in WebCT that I've named for this
purpose. The bulletin board will be closed at 8 am the day before
the "HW review" lecture, and I'll choose the mostfrequently
requested problems. 
11 Sep 2002 
The page of equations you will be supplied
in Exam 1 can be downloaded and printed from this directory: http://dusty.physics.uiowa.edu/~goree/teaching/12_formulae/
The only difference, as compared to the copy you will get in the exam,
is that the exam copy will be printed on colored paper. Similar pages
for Exams 2, 3, and the Final Exam will appear in this same directory
at a later date, a few lectures before the exam. 
12 Sep 2002 
A sample exam is here.
This sample illustrates the types of questions and the format of the
exam. The questions in the sample exam happen to represent some of
the material in Exam 1. There will be no additional sample exams provided
for Exams 2, 3, or the final exam, as they will be similar to Exam
1 except in the material covered, as listed in the schedule. 
24 Sep 2002 
Exam 1 scores:
 Your score is now posted on WebCT. Instructions
on how to use WebCT appear above. The systems
administrator tells me that WebCT will be down from 10 PM this
evening to 4 AM tomorrow morning.
 The maximum possible score was 15, and the highest
actual score was 14. The mean score was 8.7, or 58% of the maximum
possible. A histogram of grades is here.
 A table listing the percentile in the class
is here.
Example: if you received a grade of 6 you can use this table
to see that you were in the 20th percentile, meaning that 20%
of your classmates scored the same or lower than you. Your percentile
standing in an exam is not used in computing your course grade;
it merely serves as an indicator of how well you are performing
as compared to your classmates.

27 Sep 2002 
 Exam 1 questions and the answer key now appear
in a pdf file on WebCT. They will remain there for the remainder
of the semester, so that you may view them when studying for the
Final Exam. They are combined into a single viewonly pdf file.
 The WebCT systems administrator advises that
WebCT is often going down, mainly at night for maintenance to
correct a hardware problem; she hopes these outages will be over
soon.

8 Oct 2002 
The manual for E8: Magnetic Fields and
Faraday's Law is missing the instructions. You can find the pdf file
here;
please print it before your lab. 
16 Oct 2002 
The page of formulae for Exam 2 is now
here:
You may vote for the HW problems you wish to see solved in the lecture
before the exam using the bulletin board provided on WebCT. 
25 Oct 2002 
Exam 2 scores:
 Your score is now posted on WebCT. Instructions
on how to use WebCT appear above.
 The maximum possible score was 15, and the highest

4 Dec 2002 
re. the number of labs that are graded:
If you haven't done 13 labs already, I recommend
that you take the makeup lab. Otherwise you will receive a zero
for the lab you missed.
Here is how it works:
There are 13 labs, and your lab grade is based on those 13 labs.
No grade is dropped in computing your grade for the lab portion
of the course. If you've done 12 or fewer labs, you may take the
makeup lab next week to replace the zero for a lab you missed. If
you've done 12 labs, you may elect to not do a 13th but you will
receive a zero for the one you miss. You must do at least 12 labs
to pass the course.
There was some false information out there:
One of the TAs informed me today that he previously told his students
that he will compute the lab grade using only the 12 highest lab
scores, dropping the lowest score if a student does 13 labs. He
was mistaken. His plan would have resulted in his students having
a grading advantage as compared to students with the other TA. I
have asked this TA to remedy this error by emailing his students
today, to recommend that they take the makeup lab next week if they
have missed a lab. If a student of this TA has missed two labs,
we can arrange an additional makeup lab. With this solution, students
of one TA are not favored over those of the other.
In a related matter, a student asked me whether
he can take the makeup lab even though he has done all 13 labs in
order to drop the lowest of his 13 lab grades. The answer is no.
The syllabus does not allow for dropping any grades.

5 Dec 2002 
All four pages of formulae
for the final exam are now here
In the Final Exam, you will be provided these four pages, consisting
of the same pages you already had for Exams 1, 2, and 3, plus a
new page for Chapters 31 and 32.
Homework assignment for Chapter 32:
 Problems: 2, 4, 34, 35, 36, 37, 50, 52
 Conceptual Questions: none
Solutions for Homework problems in Chapters 31
and 32 will appear on WebCT one day earlier than the day indicated
on the lecture schedule.

6 December 2002 
regarding the number of labs that are graded:
The following information replaces the announcement
of 4 Dec. that appears above:
I'm reducing the requirements for the lab portion
of the course.
Here's the new grading policy for the labs:
Only your best 12 labs will count. If you take
more than 12 labs, I will use the best 12. If you take only 12 labs,
I will use all 12. (This represents a change from my original plans,
which were to use 13 labs in computing your course grade, without
dropping any grades.)
One thing that remains unchanged is that you must
do a minimum of 12 labs to pass the course.
This change is the result of my discovering that
over half the class believed that only 12 labs would be used in
computing the course grade. I discovered this problem originally
on Wednesday, when I thought it affected only the students of one
TA. Today, after lecture, I discovered that it also affected at
least half the students for the other TA as well, judging from the
attendence for the 13th lab (Geiger Counter).
To solve the problem, my criteria are to treat
students equally so that students of one TA are not favored over
students of the other TA, and also to minimize disruptions in your
plans. This leads me to make the change described above.
Regarding the makeup lab scheduled for the last
week of classes, anyone can take this makeup lab. If you have more
than 12 lab grades as a result of taking the makeup lab, I will
use the best 12 lab grades.
If you have any questions, please feel free to
ask me.

23 December 2002 
Course grades are now posted on WebCT. Letter grades
were assigned as described above.
How your grade was computed:
The column labeled "total weighted" score was computed
as 0.75*examtotal% +0.25*lab% where the 0.75 and 0.25 are the weighting
factors described above; examtotal% and lab%
are ratios of your scores as compared to the maximum possible. I
then ranked everyone's total weighted score from top to bottom,
and used the College scale described above
to assign letter grades. Grades very close to borderline between
letter grades were given either a + or a  shading so that the total
number of grades with a + shading is the same as the total number
of grades with a  shading; most students received a grade that
was not shaded.
Histograms appear here:
Note that lab scores had an extremely compressed
distribution whereas the exams had a very wide distribution. The
two distributions had standard deviations, compared to their mean,
of about 1% and 30%, respectively. Consequently, your course grade,
which was determined by rank in class, was affected very little
by your lab score. Indeed, if one were to swap the best total lab
score for the worst,among students who did 12 labs, it would have
about the same impact on the course grade as missing just one question
on an exam.

 A simple scientific calculator that does arithmetic, squares and exponents,
roots, trig functions, and scientific notation, is best for the exams.
It should have a numerical display only.
 You are not permitted to use a calculator with a display capable of
showing graphs, formulas, or text messages.
