Discussion Section

There is a discussion section scheduled for this course, in which the Teaching Assistant will answer any questions you might have about the material covered in lectures and provide assistance in solving homework problems. Beginning on Wednesday, January 21, the discussion section will meet every Wednesday, 6:00-6:50 p.m., in DuSable 204.


Course Requirements and Grading

There will be five 100-point exams, administered on the schedule below, for a total of 500 points possible in the course. (Make-up exams will be administered only to students who are forced to miss a scheduled exam due to illness, family tragedy, or an unavoidable schedule conflict with an academic or athletic activity sponsored by NIU. In all cases, documentation must be provided to show that missing the scheduled exam was unavoidable.) Homework assignments are posted on the website, and sets of homework will be collected on exam days. Homework is not required, but you will receive two points for each set of homework assignments you turn in, which will count as extra credit. Attendance at discussion sections is also not required, but you will receive one extra-credit point for each week that you attend a discussion section. Thus, there will be 24 extra-credit points possible in the course (approximately 5 percent of the total points possible in the course). The grading scale is as follows:

A = 90% (450+ points)
B = 75% (375-449 points)
C = 60% (300-374 points)
D = 50% (250-299 points)
F = below 50% (0-249 points)

The Learning Environment

Each student in the class has paid for the right of access to a learning environment that is respectful of the effort to learn, conducive to effective learning, and free of disruptions that interfere with the ability to concentrate and learn effectively. The behavior of each student in the class shall be respectful of this right. Accordingly, students shall (1) refrain from talking with fellow students during class, (2) refrain from sleeping in class, (3) refrain from non-course reading in class, (4) not leave the classroom during class, and (5) turn off cell phones upon entering the classroom. Behavior that violates any of these rules will be considered disruptive of the learning environment. A student engaging in disruptive behavior will be asked to leave the class and may, under university regulations, be suspended from the class.
