400  439  40%  54.9%  D  You mastered some essential concepts. 
0  399  0%  39.9%  F  You did not master essential concepts. 
Textbook Readings and Homework: The schedule is shown below. Notice that you are assigned to read a textbook section and do the homework problems for that section before we discuss the section in class. Notice also that the homework is always due at the start of class. I will accept early homework, but I not accept late homework for any reason.
Class Meetings: It is not my intention to deliver all the mathematical content of the course to you by lecturing during class. (You will learn much of the mathematical content by reading the textbook and doing homework problems before class.) In class, I will lecture some and you will work in groups to discuss and solve problems.
Exams: The exams will be partly made up of exercises from the textbook. This includes the exercises that you are assigned for homework and also exercises that are not assigned but that deal with concepts that this course covers. The exams will also be made up of content from classroom discussions and activities.
Attendance: Students who are absent more than six times will automatically fail the course. It does not matter whether you are absent because you are sick, taking part in an Ohio University activity, tending to a personal or family emergency, or simply skipping class. Six is the number. If you miss a class, it is your responsibility to copy a classmate's notes and study them. I will not use office hours to teach topics discussed in class to students who were absent.
Outside Activities: A university offers many opportunities in addition to courses, and I encourage you to take advantage of these. But be careful about taking on activities that conflict with class meetings or interfere with your studying, even if they are "Approved University Activities". Those terms simply refer to activities that are run by Ohio University departments or organizations. The fact that an activity is run by a university department or organization does not mean that it is somehow a substitute for class time or class work. This course is designed so that if you read the textbook, do the homework, attend class, and take the exams, you will have a very good chance of getting a good grade. Any outside activity that interferes with your attendance or your studying for this class will affect your performance on homework and exams and will thus affect your course grade. If you are taking part in an activity that will cause you to miss class, it is important that you discuss this absence with me in advance to determine whether or not you will be eligible to makeup an exam that may be scheduled on that day. I will never offer a makeup exam for an activityrelated absence that was not discussed with me in advance.
Tentative Schedule (Revised Version, posted Thursday, November 8, 2012): This schedule is only tentative. Homework and exam dates may change as the semester proceeds, either because of weather delays or because of changes in the pace of the class.
