To promote and maintain that environment, all pagers, cellular phones, and other autonomous means of communication shall be deactivated during instructional periods. RINGING OF CELL PHONES DURING CLASS WILL RESULT IN POINTS DEDUCTED FROM YOUR CLASS ROOM PARTICPATION AND PROFESSIONAL CONDUCT GRADE. Participants are expected to come to class prepared to actively participate in class. Americans with Disabilities Act: Students with disabilities who need accommodations to achieve course objectives should file an accommodation application with Learning Services, Cedar Hall 2063 and provide a written plan of accommodation to your instructor prior to the accommodation being provided. Student Evaluation: Final Exam – A comprehensive final exam totaling 20% of your final grade will be administered during finals week. Unit Exams - Exams will be given after every 3 or 4 chapters totaling 40% of your final grade. Missed exams must be made up on or before the next class period. In a rare situation where the exam can not be made up in that time period, the student will need to make up the exam during the final exam week and this exam will be different than that taken by the rest of the class. All exams will be cumulative. Labs - Labs will be worth 30% of your final grade. Labs will be done in groups of up to four people. You will lose a point per minute late if you are late to a lab. THERE WILL BE NO MAKE UP LABS!!! Class Room Participation and Professional Conduct - 10% of your final grade. Half of this grade or 5% of your final grade will be determined based on the “Assessment_of_Contributions_of_Group_Members “ sheet. Points will be added to classroom participation and professional conduct grade based on the following: 1. Arrival at class by 8 am (50 % of class participation grade) 2. Performing in class problems 3. Helping lab partner or other lab groups. 4. Helping other classmates. Points will be deducted from the classroom participation and professional conduct grade for the following: 1. Inappropriate language or jokes. 2. Ringing of cell phones in class. 3. Disrupting the class. 4. Leaving class early or not arriving back to class by 9:00, after the 8:00 break. 5. Not cleaning up workspace at the end of the class.
