You are expected to attend every class meeting. Class attendance means that you come to class on time and stay for the entire class period. Independed of your class attendence, it is your responsibility to learn the material covered in class, and that from the corresponding sections in your textbook. By not attending a class meeting you can loose credit if you miss a quiz.

Homework will be assigned on a regular basis and appear in the course schedule. There will be two types of assignments:

**Online Homework**: Part of the homework will be online in WileyPlus. You will be given a free registration code in class. Please to go to http://wileyplus.com, click the green "Get started" button, pick "OKLAHOMA STATE UNIVERSITY MAIN CAMPUS", and pick "Differential Equations" (MATH 2233 Section 001) with instructor "Mathias Schulze". Then click "Create Account", agree to the User Licence Agreement, and enter your registration code. One the next page please enter your complete name, your email address, your OSU student ID, and choose a password. Finally you can proceed to your new WileyPlus account and start working on the first online homework assignment.**Paper Homework**: All problems numbers posted in the course schedule are paper homework. The numbers are referring to your textbook. Please turn in your solutions at the end of the lecture at the given due date. If there is no lecture that day, please put your solutions in the drop box at the math office MS401 before 1:00pm. Late submissions will not be accepted. Make sure that you write your and my name and the course and section number on the front page. Your paper homework will be graded by a grader and returned in one of the following class meetings.

There will be 3 midterm exams and a final exam. Date and time for each exam will be announced in class and appear online in the course schedule. Make-up exams will be given only under exceptional circumstances and if you contact me in advance.

Be prepared for 5-minutes in-class quizzes. These quizzes will not be announced and there are no make-up quizzes.

Books, notes, electronic devices, and any kind of headwear that covers part of your face are not permitted during exams or quizzes.

To gain credit your answers must be clearly presented. Your work must show how you proceeded to find the answer or why your answer is correct. Scratch work should be clearly separated from what is to be graded and the final result should be marked by drawing a rectangle around it.

Your course score will be the maximum of the scores computed based on methods A and B below.

Homework+Quizzes | 3 Midterm Exams | Final Exam | |

Course Score (Method A) | 30% | 3 x 15% | 25% |

Course Score (Method B) | 30% | 3 x 10% | 40% |

6-Weeks Score | 50% | 1 x 50% | NA |

Your course/6-weeks score will be truncated to an integer percentage and determines your course/6-weeks letter grade as follows.

Score | 0-49% | 50-64% | 65-79% | 80-89% | 90-100% |
---|---|---|---|---|---|

Letter Grade | F | D | C | B | A |

Curving may be applied in form of a linear adjustment to all scores on a particular exam. I reserve the right to decide borderline cases based on class attendance and subjective impressions such as effort and conscientiousness.

Your starting points are the textbook and the lecture. It is easier to follow the lecture if you have seen the material before and presented from a slightly different point of view. I strongly recommend that you read each section in your textbook at home before it is covered in class. Try to isolate what you do not understand and be prepared to ask questions in class.

Do not hesitate to ask questions. If something is unclear to you in class, just ask. You can be sure that other students have the same question but do not dare to ask. If you let me know what your problems are, I can adapt the lecture and make it easier for you to follow. There are no stupid questions. On the contrary, asking the right question is often an important step in the process of solving a problem.

The importance of working on example problems can not be overemphasized. Work on the homework assignment intensively and pick additional similar problems from the exercises sections of your textbook.

Discussion is crucial to understand mathematics. I strongly encourage you to discuss both the material covered in class and your solutions of the homework problems with other students in your section. The best way to check your own understanding is to explain to someone else.

If you realize that you do not understand the homework problems, seek help immediately. With a backlog of not understood material it extremely difficult to catch up with the class again.

The Mathematics Learning Resource Center (MLRC) provides free tutoring sessions for this course Tuesdays and Thursdays from 6:00pm to 9:00pm. The MLRC is located on the 4th floor of the classroom building and you need to check in for tutoring in room CLB 420. For more information, see http://www.math.okstate.edu/mlrc.

You are always welcome to see me in my office hour or contact me by email if you have any questions or problems. If my office hours do not fit your schedule, please contact me by email for an appointment.
