After reviewing their marks to this point, students should make an appointment with the instructor to discuss their progress and concerns if the cumulative total to this point is less than 50%. The instructor is also available prior to this in designated office hours if students have any concerns. The RDC Final Examination Policy will be followed with respect to Final Examinations. Please review this document to ensure you understand the contents and implications of the policy. Final grades will conform to the letter grade system, as outlined in the College Calendar. It`s student responsibility to be aware of assignment and project due dates. Attendance requirements: The faculty of the Department believe that students are committed to their program and learning experiences. However, it is understood that there are times when students may be absent from those experiences. Any absence can be viewed as a potentially serious disruption of the learning process and necessary achievement of the learning objectives. It is the student's responsibility to make up any missed coursework in lectures or labs. Extra assistance will only be given to students who have attended all classes and labs. Academic Misconduct: Please become familiar with what constitutes academic misconduct, as well as the consequences. Plagiarism involves submitting work in a course as if it were the student’s own work. Plagiarism may involve the act of submitting work in which some or all of the phrasing, ideas, or line of reasoning are alleged to be the submitter’s own but in fact were created by someone else. The complete policies are available on the RDC Policies web site: Appeals: Formal Policy, Appeals: Informal Resolution Policy and Student Misconduct: Academic and Non‐Academic Policy. Changes to the Course Outline: Changes to the course outline will be made with the consent of the course instructor and students. Changes will be reviewed by the Department Chairperson for consistency with College policies. EET115: DC Machines Attendance is required for all exams and quizzes. Any student who, due to extenuating circumstances, will be late or absent must notify the instructor before the start of the exam or quiz. Failure to notify the instructor indicates a serious breach of professional and ethical conduct. Valid documentation will be required for missing any assessment. In most cases, make up activities will not be available. Late or missed assignments: Assignments submitted one or two days late will be subject to a penalty of 5% per day. Assignments submitted more than two days late will not be accepted, and will receive no grade. While students are encouraged to help each other, assignments must be individual work, unless designated as group assignments. In cases of plagiarism, no marks will be awarded. Please refer to College policy on Academic Misconduct for other possible disciplinary action. 4 Electrical Engineering Technology Important Dates: April 9 April 14 April 18 April 21 April 28 Other Notes: First Day of Classes for Winter term Last day to register or add/drop Winter courses Last day to have tuition refunded for Winter term 2014 courses Family Day, College closed Midterm Break for Winter 2014 term, no classes Classes resume Emergency Response Day for Winter 2014 term Final Exam Schedule posted Continuing student registration begins for 2014‐2015 Last day withdraw from Winter term 2014 courses and receive a WD.
