professor, you are encouraged to email your questions or
issues to yang@uhcl.edu and, if necessary,
set up a time with the professor to have an online meeting. Emails are
typically replied within 24 hours. If you have not received a response within
24 hours, either send a reminder email or leave a message at (281) 283-3835. - Using emails effectively: Emailing has become an indispensable
tool in most work places. Emails without a subject line or the
signature line will be considered as potentially malicious and be discarded. Here is a sample subject
line: "CSCI 4323 Lab #1, question 3". The signature line should
have your full name and the name of the class. Although email messages tend to be
informal, please check the grammar and spelling of your messages to ensure
their legibility. Try to provide sufficient details in
your email message, such as the problem(s) you have encountered, the
solution(s) you have tried, and the outcome you have got from these
solution(s). Teaching assistant info and office hours

NOTE: The following schedule will
be adhered to as closely as possible, although changes are probable. Always
check with your instructor if you are not sure about what would be covered
next week.
Attendance Policy: You are expected to attend all classes. If you have ever missed a
class, be sure to watch the recorded session to learn what had been covered.
It is your responsibility to get hold of whatever may have been discussed in
the class.
+ Class
Participation: Participating in the
class is expected. You should ask or answer questions during the in-class or
online discussions. Grading Scale: The accumulated points from all the
categories determine a person's final grade. There will be no extra-credit
projects.
Grading policy: -
All students are graded the
same way according to the grading scale posted above. -
Unless a grading error is
found in an exam or assignment, a student’s grade will NEVER be changed once
it is assigned. -
No extra projects or
assignments would be given to an individual student to help improve his/her
grades. Advices: o Your grades will be continually updated in the Canvas. It is your
obligation to monitor your grade-in-progress regularly, and immediately ask questions
or seek help if you are concerned. o Once a grade is assigned and posted (in the Canvas), a student may
appeal for correction of the assigned grade (if a grading error is found) within
a week. After that, the grade is finalized. o Never bother to appeal for a change of your grade once it is finalized;
the best and proper time of improving your chance of earning a good grade is
before it is finalized. Quizzes, Tests, and Exams: Both analytic and synthetic abilities are emphasized. Being able
to apply the learned knowledge toward problem solving is also highly
emphasized in the tests. Unless due to unexpected, documented
emergency, no makeup tests or quizzes will be given. Assignments will be posted on the class
web site as well as in the Blackboard. The due date and time of each
assignment is specified when it is published in the Blackboard. - Identification
page: All assignments must have your name, and course
name/number/section number (e.g., CSCI 4323) at the top of the first page. - Proper
organization of submitted material: If your submission include multiple
documents, combine all of them into a single document (for example, a single
PDF or ZIP). - Order! Order! Arrange the
solutions following the sequence of the questions. Write the question number
at the top-right corner of each page. - Word
processing: It is required that you type your reports (e.g., print them using
a printer). Use a word processor and appropriate typesetting and/or drawing
tools to do the assignments. Spellcheck the whole document before
printing it. You may lose points due to spelling or grammatical errors. A note about problem-solving: An important part of problem solving is correct understanding of the
given problem. -
Try to have a good grasp of
the problem before starting the process of finding the solution(s). -
Use any resources, including
the instructor, the TA, your classmates/friends, and online resources to
ensure that you have correctly understood the given problem. -
While trying to figure out
the solution(s), continue to verify your understanding of the problem. -
Read the given instructions
carefully before taking any action; while preparing
your solutions, be sure to follow the given instructions. NOTE: When a grade is assigned, the grade can
only be appealed within a week after
the grade has been posted. Always review a graded lab or test immediately and, if
needed, talk to the instructor within a week. Academic Honesty Policy: NOTE: Unless otherwise specified, all assignments, projects, quizzes, tests
and exams are individual work. Students
should take caution not to violate the academic
honesty policy specified by the university. Per the UHCL
academic honesty policy, plagiarism is defined as follow. Plagiarism: a. Incorporating the work or idea of another person into one’s own work
without acknowledging the source of that work or idea. b. Attempting to receive credit for work performed by another person,
including papers obtained in whole or part from individuals or other sources. c. Copying copyrighted computer programs or data files belonging to
someone else. Visit http://cse.uhcl.edu/yang/citing.htm for more
information about cited references. Instructor's
Notes: - Important: If you think
you have lost some points due to grading errors, make sure you approach the
instructor within a week
after the assignment, project, or test has been graded. - To get the most
out of this class, you need to read the textbooks and spend time using
computers regularly. Be prepared for a class by previewing the material to
be covered in that class and participate in discussions and problem-solving
exercises, if applicable, in the class. - Taking notes and understanding what are
covered in classes are essential for successfully passing the exams. - As a student being
trained to become a professional person, you are expected to behave according
to the professional codes of conduct (e.g., the IEEE
Code of Conduct) or code of ethics (e.g., the ACM Code of Ethics). As a starting point, listed below are
some of the common behaviors that do not conform to the codes of ethics: - Being
regularly late for the class. - Chatting
with another person while the instructor or someone is giving a speech in
class. - Being
regularly late when submitting assignments. - Asking
the instructor or the TA for a favor when submitting a late assignment. - Checking
out others’ answers during an exam. - Continuing
to write when an exam’s time is up, or submitting an online exam past the due
time. - Violating
academic honesty when working on the assignments or exams. - Using
others’ write-up without proper citing when writing a paper or report. - …
