Evaluations Lab report Evaluation Date: Ongoing Evaluation Percentage: 15
Students form groups of 2 students per group to run the lab experiement and record the results. Each group submit only one lab report. There are 4 lab experiements, with each lab experiement requiring a seperate lab report. Lab reports are submitted at the end of a 3 hours lab session. 2
Each lab report includes a prelab component which the student must prepare before coming to the lab session. The prelab component of the lab report is worth 30% of the total lab mark. Upon completing the lab expereiment and finsihning the lab report, the TA will assign the remaining 70% of the lab mark based on the students's performance during the lab sessions Date

Final Mark and Grading Formula In order to pass the course, the student must have scored at least 50% of the "written component" of the evaluation, where by the written component it is meant the combination of the Mid-Term and Final Exams. More precisely, the formula used to calculate the final mark on the course is given as follows. IF 20% of (MidTerm-Exam Mark) + 50% of (Final-Exam Mark) >= 35/100 , THEN: FINAL MARK=15% of Labs Mark+ 15% of Quizes marks + 20% of (MidTerm-Exam mark) + 50% of 4
(Final-Exam mark) ELSE: FINAL MARK = Failure Mark (D,E, or F) Couse Materials: All course materials will be relaesed in the Blackboard Learn (click here). ATTENDANCE: Attendance at courses of instruction, laboratory periods and discussion groups is mandatory according to the faculty guidelines. Failure to attend at least 80% of all classes and DGD’s without unauthorized excuse will be treated seriously and offending students will not be admitted to the final exam. An attendance sheet will be passed at the beginning of each lecture and DGD; students will be required to sign this sheet to indicate their presence. Please refer to the faculty rules (click here) in this matter.

Plagiarism
Beware of academic fraud! Academic fraud is an act by a student that may result in a false evaluation (including papers, tests, examinations, etc.). It is not tolerated by the University. Any person found guilty of academic fraud will be subject to severe sanctions. Here are some examples of academic fraud: Plagiarism or cheating of any kind; Present research data that has been falsified; Submit a work for which you are not the author, in whole or part; Submit the same piece of work for more than one course without the written consent of the professors concerned. Please consult this webpage: it contains regulations and tool to help you avoid plagiarism. An individual who commits or attempts to commit academic fraud, or who is an accomplice, will be penalized. Here are some examples of possible sanctions: Receive an “F” for the work or in the course in question; Imposition of additional requirements (from 3 to 30 credits) to the program of study; Suspension or expulsion from the Faculty. You can refer to the regulations on this webpage.
Student Services Academic Writing Help Centre At the AWHC you will learn how to identify, correct and ultimately avoid errors in your writing and become an autonomous writer. In working with our Writing Advisors, you will be able to acquire the abilities, strategies and writing tools that will enable you to: Master the written language of your choice Expand your critical thinking abilities Develop your argumentation skills Learn what the expectations are for academic writing Career Services Career Services offers various services and a career development program to enable you to recognize and enhance the employability skills you need in today's world of work. Counselling Service There are many reasons to take advantage of the Counselling Service. We offer: Personal counselling 7
Career counselling Study skills counselling Access Service The Access Service acts as intermediary between students, their faculty, and other University offices to ensure that the special needs of these students are addressed and that the best possible learning conditions are being offered. Note that the University of Ottawa is affiliated with AERO and ACE services for the adaptation of accessible academic materials for students with perceptual disabilities. If you have any questions, please contact the Accessibility Librarian or the Access services for textbooks.
Policy on the prevention of sexual violence The University of Ottawa will not tolerate any act of sexual violence. This includes acts such as rape and sexual harassment, as well as misconduct that take place without consent, which includes cyberbullying.
