Attendance Policy Attendance is recorded on a weekly basis. Online course attendance is determined by the submission dates for: assignments, assessments, discussion postings, etc. Logging into D2L is insufficient to verify/validate attendance for online courses. Student Expectations It is vitally important that you play an active role in the learning process. As a result, your participation in class discussion threads is required. The 4 P’s of student involvement in class are: 1. Preparation (read the assigned material) 2. Presence (routinely log in to D2L class) 3. Promptness (post thoughts, ideas, comments, etc. regularly) and 4. Participation (get actively involved). The student is expected to participate in the course via e-mail exchanges (or other communication) with the instructor, by reading the assigned readings, submitting comments to the discussion forums, submitting assignments, and completing assignments in a timely fashion. Students are expected to check their e-mails daily and the announcements at least every 48 hours.

Evaluation and Assignments Syllabus Quiz:  There is a short quiz that must be completed during the first week of the class. The quiz will be posted under the Assessments Tab on D2L. Tests:  There will be 5 unit exams given throughout the semester. Exams will consist of short answer and problem solving questions. You are not to collaborate with others on exams. If you have questions, talk with me. You will need a calculator to assist you in solving problems.  Exams are also to be submitted on D2L to their appropriate dropbox. You will need to scan your work to submit it. One great tool is the CamScanner app. This free app will allow you to scan and save objects as PDFs. There are several other apps that convert pictures to pdfs. Quizzes:  There will be 12 multiple choice chapter quizzes. Quizzes are to be accessed under the Assessments Tab on D2L.  The quizzes will be worth 5-10 points each. Quizzes are not timed, you are allowed unlimited attempts, but only your first submission will be graded. You are free to stop

Page |3 and resume progress, but be sure to save your answers. Pay attention to their due dates. Problems Sets:  There will be 5 unit problem sets that correspond to each unit’s readings.  Problem Sets can be found under content in their corresponding unit on D2L.  Problem Sets are worth 25 points each. o For full credit all work must be shown. “All work” means showing any equations and mathematical steps used to solve the problem, as well as the answer. Excel may be used as an aid, but work must still be shown. o Problem Sets are to be submitted on D2L to their appropriate dropbox. You will need to scan or take a picture of your work to submit it. One great tool is the CamScanner app. This free app will allow you to scan and save objects as PDFs. There are several other apps that convert pictures to pdfs. Discussion:  There will be 1 discussion, outside of the introduction post, this semester. Each student is required to post an original answer to the question. Each student will also be required to post a response to at least one (1) classmate’s post. Each discussion board is worth 25 points: 15 points for the initial post and 10 points for your substantive response to a classmate’s post. The discussion will take place on D2L.

Make-up/Late-work Policy:  Problem Sets: I will accept late submissions for partial credit. Answers to the problem sets are posted on D2L shortly after they are to be submitted for grading. Once the answers are posted online, the best you can score is a 12.5 out of 25 points.  Discussion: No late submissions will be accepted for credit.  Exams: Exams must be taken during the open examination period. The only exceptions to this rule are those students that will not have internet access because of a school related function, have scheduled a testing time with the disability services office, or have some valid extenuating circumstance arise. Individuals with a school related activity or whom plan to test with disability services must schedule their testing time in advance. Academic Success Support/Starfish As your instructor, I am personally committed to supporting YOUR academic success in this course. For that reason, if you demonstrate any academic performance or behavioral problems which may impede your success, I will personally discuss and attempt to resolve the issue with you. I may also refer your case using Starfish, which is an online student success program.

If you receive a “flag” in Starfish, please come see me or seek assistance and support from your advisor or other resource staff member on campus. Please make sure to update your Starfish profile at the beginning of each semester (including a photo and up-to-date contact information). The Starfish link is located in D2L at the very top left corner of the homepage. My goal is to make your learning experience in this course as meaningful and successful as possible. If you have questions regarding Starfish, please contact the Student Success Center at 605.626.2633 or [email protected]. Academic Dishonesty Cheating and other forms of academic dishonesty and misconduct run contrary to the purposes of higher education and will not be tolerated. Academic dishonesty includes, but is not limited to, plagiarism, copying answers or work done by another student (either on an exam or an assignment), allowing another student to copy from you, and using unauthorized materials during an exam. Northern State University's policy and procedures on cheating and academic dishonesty as outlined in the Northern State University Student Handbook apply to this course. The consequences for cheating and academic dishonesty in this class include receiving no or reduced credit for the assignment and failing the course. Students may also fail the course after receiving failing or reduced grades for affected assignments. Americans with Disabilities Act (ADA) Statement ADA Statement: Northern State University is committed to providing reasonable accommodation for students with physical, learning, mental health and/or other types of disabilities. Accommodations for students with disabilities are made only in consultation with the Director of Disability Services. If you believe you have a disability, either temporary or permanent, requiring accommodation, contact Doris Stusiak (contact information below). NSU can show you how to secure proper documentation and help you arrange appropriate accommodations as mandated by the Americans with Disabilities Act.

Page |5 Freedom in Learning Under Board of Regents and University policy student academic performance may be evaluated solely on an academic basis, not on opinions or conduct in matters unrelated to academic standards. Students should be free to take reasoned exception to the data or views offered in any course of study and to reserve judgment about matters of opinion, but they are responsible for learning the content of any course of study for which they are enrolled. Students who believe that an academic evaluation reflects prejudiced or capricious consideration of student opinions or conduct unrelated to academic standards should contact the academic dean administratively in charge of the class to initiate a review of the evaluation.
