Attendance:
Students are to sign in for each period.
It is the student’s responsibility to drop
all
classes in which he/she is no longer attending
.
It is the instructor’s discretion to withdraw a
student after the add/drop deadline
(
March 30
)
due to excessive absences.
Students who remain
enrolled in a class beyond the published withdrawal deadline, as stated in the class schedule, will
receive an evaluative letter grade in this class.
The final grade in this class will be affected
by
active participation, including attendance, as
described under the paragraph on Class
W
ork.
Classroom behavior and student code of conduct:
Students are expected to respect and obey
standards of student conduct while in class and on the campus. Refer
to Policy 3100, Procedures
3100.1 and 3100.2, current college catalog and student handbook for guidance. In particular,
cheating, plagiarism or other forms of academic dishonesty are not acceptable and will not be
tolerated.
Accommodation of disability:
Students with disabilities who may need academic
accommodations should discuss options with the professor during the first two week of class.
Examinations:
There will be four quizzes
lasting two hours
each
covering recent course
materials throughout the
semester.
The best three scores
will
count toward the final grade.
There
will also be a final comprehensive
two

hour
examination. The exams are all closed book, but a
note card is allowed for the quizzes and a note sheet will be provided for the final exa
m.
Class Work:
To encourage interactive learning, students will be presented with class problems
to solve in each lecture period.
Turning in the solution or s
igning in
for each lecture period
provide
evidence of participation, for which credits are earned
. In cases of absence or late show,
credits can be restored only if valid excuse is given.
Homework:
Fifteen sets of homework are assigned. Each set is due at the first class period of
the week.
Full score is based on successfully solving 70% of each ass
igned set.
They will be
selectively graded and they all co
unt toward the final grade. A 2
0% reduction applies to late
5
submission within the week. No credit will be given for later submission. The work should be
neat and legible. Reasoning should be clear.
Answers will be posted on the course website after
the due dates.
Laboratory
:
Students work in a team of about 6, and compose a group report to be turned in at
the end of the lab period. Lab manual for each experiment can be downloaded from the course
website. There will be no make

up for absences. Scores are based on correctness, clarity,
accuracy, and active participation.
Reading:
Since the number of topics covered is very large, it will be impossible to go over all of
them in class. The lectures w
ill be devoted to discussions of critical concepts and methods.
Students are expected to learn many of the topics by reading the
lecture notes available freely
online, or the recommended
textbook, and to come to the class having alr
eady read the relevant
s
ections.
They should consult the schedule for the sections to be covered in each class period.
