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 d
iscretion to withdraw a
student after the add/drop deadline 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 studen
t 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
ea
ch
covering recent course
materials throughout the semester.
The best three scores
will
count toward the final grade.
There
will also be a
mandatory
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
exam.
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

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 assigned set.
They will be
selectively graded and they all co
unt toward the final grade. A 2
0% reduction applies to late
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. The best 9 scores of 10 experiments are counted toward the
final gra
de.
Reading:
Since the number of topics covered is very large, it will be impossible to go over all of
them in class. The lectures will be devoted to discussions of critical concepts and methods.
Students are expected to learn many of the topics by readin
g the
lecture notes available freely
online, or the recommended
textbook, and to come to the class having alr
eady read the relevant
sections.
They should consult the schedule for the sections to be covered in each class period.
