5 ELEN DEPARTMENT POLICIES ELEN Department Passing Grade Requirements Policy Students must obtain a passing grade (at least 50%) in both the lecture component and the laboratory/practical component of the course. If the student receives a failing grade (less than 50%) in either the lab or lecture component, the final mark for the whole course will be no more than 50%. Note: Students must obtain an overall 60% GGA (Graduating Grade Average) to be awarded a Diploma in. ELEN Department Laboratory Attendance Policy Attendance of each lab period is mandatory. If a student misses a lab period due to illness, a doctor s note must be provided. In that case, that lab will not count for or against the student. Any student missing three or more labs, regardless of the reason(s) will be awarded a maximum final mark of 49%; you will fail the course overall. Laboratory attendance will be recorded. ELEN Department Collection of Student Work Policy This is a requirement of the accreditation process. At the end of the semester, each professor is responsible for collecting a representative sample of student's work from the term. This may include any work completed during the term such as assignments, labs, or exams. This copy will be redacted and archived. Occupational Health and Safety Course requires the use and handling of hazardous material/equipment, all students are required to follow the health and safety guidelines during labs OKANAGAN COLLEGE POLICIES Okanagan College Academic Misconduct Policy: Any incidents of academic misconduct, as outlined in the Academic Offences policy in the Okanagan College calendar, may result in a mark of 0% or another consequence permitted by the policy. In cases of severe or repetitive misconduct, the Dean s office and the College Registrar will be notified and the student may be given a failing grade for the course or a more serious consequence as permitted by the policy, such as expulsion. The Academic Offences policy can be located online at the following link: Okanagan College Student Notification of OC Policies: Okanagan College requires that students are informed of acceptable student conduct specifically relating to OC Student Non-Academic Conduct and Student Academic Offences policies. Student Non Academic Conduct: What Is The Disruption Of Instructional Activities? At Okanagan College (OC), disruption of instructional activities includes student conduct which interferes with examinations, lectures, seminars, tutorials, group meetings, other related activities, and with students using the study facilities of OC, as well as conduct that leads to property damage, assault, discrimination, harassment or fraud.

6 Penalties for disruption of instructional activities can include a warning and/or a failing grade on an assignment, examination or course, or possible suspension from OC. The complete policy is available online at: Academic+Conduct+Policy.pdf Student Academic Conduct: What Is Cheating? Cheating includes but is not limited to dishonest or attempted dishonest conduct during tests or examinations in which the use is made of books, notes, diagrams or other aids excluding those authorized by the examiner. It includes communicating with others for the purpose of obtaining information, copying from the work of others and purposely exposing or conveying information to other students who are taking the test or examination. Students must submit independently written work. Students may not write joint or collaborative assignments with other students unless the professor approves it in advance as a group/team project. Students who share their work with other students are equally involved in cheating. What Is Plagiarism? Plagiarism is defined as the presentation of another person s work or ideas without proper or complete acknowledgement. It is the serious academic offence of reproducing someone else s work, including words, ideas and media, without permission for course credit towards a certificate, diploma, degree and/or professional designation. The defining characteristic is that the work is not yours. Intentional plagiarism is the deliberate presentation of another s work or ideas as one s own. Intentional plagiarism can be a copy of material from a journal article, a book chapter, data from the Internet, another student, work submitted for credit in another course or from other sources. Unintentional plagiarism is the inadvertent presentation of another s work or ideas without proper acknowledgement because of poor or inadequate practices. Unintentional plagiarism is a failure of scholarship; intentional plagiarism is an act of deceit. What Are The Students Responsibilities To Avoid Plagiarism? Students have a responsibility to read the OC Plagiarism Policy and Procedures outlined in the OC calendar, which is available online at: Students are responsible for learning and applying the proper scholarly practices for acknowledging the work and ideas of others. Students who are unsure of what constitutes plagiarism should refer to the UBC publication Plagiarism Avoided; Taking Responsibility for your Work. This guide is available in OC bookstores and libraries. Students must acknowledge the sources of information used on all their assignments. This usually involves putting the authors name and the year of publication in parentheses after the sentence in which you used the material, then at the end of your paper, writing out the complete references in a Reference section. Students are expected to understand research and writing techniques and documentation styles. Unless otherwise directed by the professor, use the American Psychological Association (APA) or Modern Language Association (MLA) style and cite references using the APA guidelines. A copy of the APA manual is available in the OC libraries, and the library website has online resources available on both major citing styles. What Are The Penalties For Plagiarism And Cheating? Okanagan College professors may actively monitor student work for plagiarism or cheating and will follow the Okanagan College Policies when an offense is suspected. A student found to have committed an offense may receive a formal letter of reprimand outlining the nature of the infraction, or further disciplinary action depending on the severity of the offense or whether this is a repeat occurrence. The Dean s Office of the Science, Technology and Health portfolio, along with the College Registrar, record and monitor all reported instances of plagiarism and cheating.
