There will be weekly homework assignments during the semester. Each homework is due Wednesday 3:00pm. Homework may be submitted in class or at the dropbox outside the instructor's office Thompson 327. Homework will not be accepted by e-mail. You must show work. Illegible or unsuppoted answers will receive no credit. Homework may submitted within 24 hours of the due date, but with an automatic 2 point deduction. After Thursday 3:00pm, no late homeworks will be accepted for any reason (including illness, family emergencies, and school-related activities). You are allowed to work with other students on the homework, but each student should write up their answers individually. At the end of the semester, the lowest homework score will be dropped and the remaining scores will be added together to compute your overall homework grade. The homework assignments are posted on the course website.
You will work in teams on a research project over the course of the semester. Your group is expected to prepare a poster, present your results at a research conference, and write a report summarizing your findings. The project proposal must be submitted by January 31st. The poster is due March 19th. The final draft of your written report is due April 23rd. The project counts for 30% of your course grade.
Midterm Exams
There will be 3 50-minute midterm exams, each counting for 10% of your course grade. The exams will be given during our regular lecture time in our regular classroom. The midterm exams will not be cummulative. No calculators or notes are allowed during the exam. No make-up exams will be given, for any reason (including illness, family emergencies, guard duty, and school-related activities). If a student misses an exam, then they will be assigned a zero for that exam and they are automatically on the second grading system.
Exam 1Wed 2/14
Exam 2Wed 3/7
Exam 3Wed 4/18
Final Exam
The final exam is scheduled for Friday April 27th, 1:00-4:00pm. The final will cover all the material we covered in the course and counts for 20% of your course grade. If you have a conflict with the scheduled exam time, you should contact the lecturer well in advance to schedule an alternate time. Not taking the final exam will result in an automatic failing grade. In extreme situations an incomplete grade can be given for missing the final, but the case must be documented and approved by the registrar.
Attendance Policy
You are expected to attend to class regularly. Missing class is not an excuse for failing to submit the homework on time. Attendance will be taken every lecture and entered into the Citadel Class Absence System. Any student that is more than 10 minutes late to lecture will be marked as late. According to Citadel official policy, any student whose total absences exceed 20% (excused or unexcused) will receive an automatic F for the course.
Academic Honesty
You are allowed to discuss your homework with your fellow classmates in general terms, but do not show your work to another student. Sharing your work or copying someone else's homework may result in a zero on the assignment and further discipline if the problem persists. If you have specific questions about your homework, ask the professor. Collaboration of any kind on the exams is strictly forbidden and will result in a failing grade for the course and academic discipline in concordance with the Honor Code.
Disability Services
The Citadel will make reasonable accomodations for persons with documented disabilities. Students should apply at the Academic Support Center. Students approved for accomodations are responsible for notifying the instructor as soon as possible and for contacting the instructor at least one week before the accomodation is needed.
