Students are expected to become proficient in reading and writing proofs.

**Methods of Assessment of Learning Outcomes:** Assessment of the learning outcomes will be achieved through homework assignments, two midterm exams, and a final exam.

**Homework Assignments:** Written homework will be assigned weekly and will be collected in class.

70%-79%, D: 60%-69%, F: below 60%

**Attendance Policy:** Students must go to lectures and

**Academic Misconduct:** Academic dishonesty is intolerable and

**Civility in the Classroom:** Texas Tech University endeavor
to foster a classroom climate of mutual respect among students and
between students and teacher. Students are expected to maintain a
classroom environment that is conducive to learning. In order to
assure that all students have the opportunity to gain from time spent
in class, unless otherwise approved by the instructor, students are
prohibited from engaging in any other form of distraction. Students
must * attend class on time and are not allowed to leave the
class before the end of the hour* without authorization.
During class time students are not allowed to eat, smoke, drink
alcohol, text, chat, sleep, play games, read newspapers, wear
earphones, play with smart phones or tablets, etc. Please put silent
mode to all your electronic devices. Inappropriate behavior in the
classroom shall result, minimally, in a request to leave class.

**Students with Disabilities:** Any student who because of a
disability may require special arrangements in order to meet course
requirements should contact the instructor as soon as possible. *I would appreciate hearing from anyone who has a disability that may
require special accommodations. I am sure we can work out whatever arrangements are necessary. Please see me during my office hours.*
Student Disability Services office is in 335 West Hall (phone:
806-742-2405).

**Advice:** Come to class regularly, work on homework problems.
Ask questions in class and get help from the Tutoring Center
(information will be provided) or from the instructor during the
office hours. Since a lot of material will be covered, students have
to master them quickly and do not wait too late until the midterms or
the final exam. Students are encouraged to give feedbacks to the
instructor during the semester.

*NOTE:* When needed, the instructor will communicate with the
students using their TTU email addresses. At the beginning of the
semester, the instructor will send an email to confirm the students' email addresses. If a student does not receive this message by the
time of the second class, he/she must contact the instructor immediately.
