Course Description: Electricity & Magnetism, Optics for students in science and engineering. This is
the second semester of a two-semester sequence in introductory physics. Topics covered include
electricity, magnetism, and an introduction to optics.
Course Objectives:
Knowledge to gain: Understanding of material covered in chapters 21-30, 32-34 of the textbook,
University Physics.
Skills to gain: Ability to work through complex problems.
Instructor: Dr. George R. Welch
Phone: 845-1571
E-mail: [email protected] (please start subject line with PHYS 208)
Office and office hours: Monday 9:30-10:30, Tuesday 11:00-12:00. I currently do not have an office in
space that is accessible to students. I will conduct office hours in MPHY-135 until further notice. If a
better space presents itself, we will move there.
Web Pages:
o ecampus.tamu.edu main course website for this class (will have lecture notes and grades)
o pearsonmylabandmastering.com – (Modified) Mastering Physics for homework submission;
register through ecampus.tamu.edu!
o www.flipitphysics.com for pre-lectures and checkpoints
o www.webassign.net/tamu/login.html for the labs
Pre-Requisites: PHYS 218 and MATH 151 or 171.
You must have a working knowledge of plane geometry, trigonometry, and algebra. You will also be
expected to have a working knowledge of derivatives and integrals, and be proficient in the use of vectors
(addition, subtraction, dot and cross products).
Co-Requisite: MATH 152 or 172.
Class times: Lectures TR 9:35-10:50, MPHY 205, plus one weekly Recitation/Lab section.
Text and required materials: The text is “University Physics," 14th ed., Young and Freedman, vol. 2,
stocked in the bookstore, or see the web-page for other versions that would suffice. Look for bundled
“Modified Mastering Physics” access, or you must purchase access to this site separately. Also you will
need to purchase an access code for WebAssign for the labs and FlipItPhysics for the prelectures. Finally,
you must have an “iClicker” for the lectures. You also should have a pocket calculator capable of
calculating arithmetic and trigonometric functions for exams.
Pre-Lectures: PHYS 208 lectures follow a “flipped course” model. We use a pre-lecture system hosted
on the online FlipItPhysics site. Please enter your UIN for your ‘unique identifier’ when registering, to
ensure that you get credit for your work. You are required to view the pre-lectures (narrated slides
including a few online questions) ahead of the lectures, and the lectures will include quizzes to see if you
have gained a basic understanding. The remainder of the lecture can then focus more on problem-solving.
The FlipItPhysics site also includes “Checkpoints” following most pre-lectures, which are short quizzes
to test for understanding. The course code for this course is: welch-208-16f.
Lectures and Clickers: The iClickers will be used for in-class conceptual testing and polling. To
encourage class participation, credit for iClickers will be based in part on participation, as well as
additional points based on correct answers. Full participation credit allows for 3 “free drops” (missed
classes), to avoid complicated accounting for excused absences. To gain participation credit you must
pre-register your device, and answer all of the questions in class. Cheating by bringing a friend’s clicker
is a violation of the Aggie Honor Code, and will result in loss of all clicker points, and disciplinary
action.
To register the iClicker, go to http://www.iclicker.com/support/registeryourclicker/, and enter your first
and last names (same as on your TAMU ID), then the TAMU UIN, then the "Remote ID" code from the
back of your iClicker. (It can also be found on the LCD screen upon powering up the remote.) Technical
problems with the clickers will likely need to be addressed to the support people at iclicker.com.
Laboratory: The lab is a part of this course, not treated as a separate grade. However, the lab part of the
course must be passed separately to pass the course. In order to pass the lab part of the course, attendance
at all labs is required (with one make-up lab available). The lab schedule is on a separate page, and
posted on the web site. The labs, along with pre-lab and post-lab assignments, will be obtained through
the online WebAssign package. Note that although we do not have a lab scheduled each week, you are
expected to attend both recitation and lab each week for full credit. Missing the lab part will result in zero
credit for the recitation quiz of that week.
Homework and Recitation: Homework assignments are posted online on the Modified Mastering
Physics (pearsonmylabandmastering.com) web site, and you are responsible for completing and
understanding these problems. By the end of the first week you should set up your Modified Mastering
Physics account and complete the first homework assignment. When you first register, you must do so via
the homework link on the eCampus site for your PHYS 208 course.
You must work the online problems on your own, and keep up with the deadlines. In addition to the
required weekly homework assignments (and follow-up problems), you can receive extra credit, up to
+20% of your homework grade, for doing the short assignments that will be due before the regular
required assignments. This is to encourage you to consolidate the lecture material while it is still fresh in
your mind. For the required homework assignments, late submissions are accepted, however full credit
will not be given. The penalty is –3% per hour past the deadline. To encourage doing the homework
(which is necessary to succeed in the course!), the maximum penalty—no matter how late—is –50%.
However, for the “Bonus” homework assignments, no credit will be given past the deadline. Details about
the grading policy for individual homework problems can be found on the online site—for example, in
some cases you get several attempts to key in the correct answer, with a 3% penalty for wrong attempts.
Exams: We will have 3 common evening exams and one final exam. The common exams are the extra
evening sessions included in the course schedule when you registered. These exams start at 7:20 PM, and
are expected to last 75 minutes. The dates are September 26, October 17, and November 14. The
location of the exams will be announced in class.
The final exam is on December 09 at 12:30 PM, in MPYH 205. There should be no conflicts at this time
since the schedules are set up by the registrar, however if you have 3 exams on one day you can request to
get one rescheduled. For such requests you need to see me before the last week of class, since last minute
arrangements are not possible. Exams generally consist of problems similar in content and difficulty to
the homework, and they are expected to include both multiple-choice and free response questions.
Formula sheets will be provided for each exam.
Absences: If you miss an exam due to an authorized excused absence as outlined in the University
Regulations, you should attempt to contact me prior to the exam, but no later than the next class
meeting following the missed exam to arrange for a makeup exam. With an official excuse, the missed
exam score will likely be replaced by the makeup exam score. Note: Few conditions qualify as an
authorized excused absence, so you must avoid missing exams except for extremely serious
circumstances. University rules related to excused and unexcused absences are located on-line at
http://student-rules.tamu.edu/rule07.
Identification: You must bring your TAMU student ID with you to all exams for identification purposes.
Course Grade: The overall course grade is weighted as follows:
3 Exams (course-wide evening exams) 42%* (14% each)
Final Exam (individual for this lecture) 26%*
Laboratory 8%
Recitation Quizzes 8%
Online homework 8%
Prelectures/Checkpoints and in-class (clickers) 8% (5% Prelectures/Checkpoints + 3% clickers)
Total 100%
* ALTERNATIVE: If your final exam grade is higher than your lowest midterm exam score, the final
exam score will be averaged with the lowest midterm exam score to replace that midterm exam score.
This will only be done if the lowest midterm score is not zero.
Grading Scale:
A: 90-100
B: 80-89
C: 70-79
D: 60-69
F: <60
ADA Policy: The Americans with Disabilities Act (ADA) is a federal anti-discrimination statute that

legislation requires that all students with disabilities be guaranteed a learning environment that provides
for reasonable accommodation of their disabilities. If you believe you have a disability requiring an
accommodation, please contact Disability Services, currently located in the Disability Services building at
the Student Services at White Creek complex on west campus or call 979-845-1637. For additional
information, visit http://disability.tamu.edu.
Honor Code: The Aggie Honor Code states, “An Aggie does not lie, cheat, or steal or tolerate those who
do.” Further information regarding the Honor Council Rules and Procedures may be found on the web at
