Assignment Overview

Discussions

You will have one or more weekly discussion assignments that allow you to demonstrate your understanding of the course material and apply knowledge to real-world situations. You will post your responses to discussion topics in discussion forums as described in the weekly course schedule below. You are required to review at least two other student postings and submit constructive feedback. All work should be complete and concise, and should demonstrate original thinking. To be complete, you must illustrate the points you make in your postings with examples from the readings, research, observation, and personal experience you may have had working in the Information Management field. You will find that most discussion topics will not display other students’ posts until you submit your individual posting. This feature encourages students to conduct their own research and formulate unique individual responses to discussion questions without being influenced by the postings made by other students. Any additional changes to your post or supplemental information you provide to your original response will not be considered toward your graded assignment.

Exercise Activities

During Weeks 2-7, you will be assigned at least one weekly hands-on exercise involving the application of material covered in the chapter reading assignments. The exercise activities may involve downloading and installing unique software tools and applications, collecting network traffic and analyzing data, and developing conclusions based on direct observation. You will post your responses in Discussion forums or as documents uploaded to a Dropbox folder as dictated in the weekly course schedule below. All work should be complete and concise, and should demonstrate original thinking. To be complete, you must follow instructions provided in each hands-on activity and produce the required deliverables as described in the reading assignments, and as described in the weekly course schedule below. Exercise assignments must  be posted to the Discussion forum or submitted to the Dropbox folder only one time, so review your final work carefully before posting/uploading them. If multiple versions of an assignment are submitted, only the first version will be evaluated and graded.

Quizzes

Quizzes: Each week you will have a brief quiz over the readings. You will have 20 minutes to complete each quiz. They will be composed of true-false and/or multiple-choice questions.


Midterm Exam

The midterm exam is a timed two-hour test composed of 50 multiple-choice items testing your understanding of Chapters 1-6. You must take it in a proctored setting.

You may use your textbook and the Internet to develop an informational explication of 500-600 words on the topic “How the explosive growth of communication systems has impacted on the quality and quantity of information.” Several focal points that should be considered are 1) the relationship between businesses and their suppliers, 2) the relationship between businesses and their customers, and 3) the impacts to consumers and the online marketplace. After posting your explication, read and respond to at least two other students’ submissions within this topic providing meaningful feedback to their posting. Your responsive postings should be substantive rather than simply an agreement or disagreement with a classmate’s position. Grading for this assignment is based both on your explication and on the quality of your comments regarding other students’ explications.

Plagiarism

Your grade will be based in large part on the originality of your ideas and your written presentation of these ideas. Presenting the words, ideas, or expression of another in any form as your own is plagiarism. Students who fail to properly give credit for information contained in their written work (papers, journals, exams, etc.) are violating the intellectual property rights of the original author. For proper citation of the original authors, you should reference the appropriate publication manual for your degree program or course (APA, MLA, etc.). Violations are taken seriously in higher education and may result in a failing grade on the assignment, a grade of "F" for the course, or dismissal from the College.

Collaboration conducted between students without prior permission from the instructor is considered plagiarism and will be treated as such. Spouses and roommates taking the same course should be particularly careful.

All required papers may be submitted for textual similarity review to Turnitin.com for the detection of plagiarism. All submitted papers may be included in the Turnitin.com reference database for the purpose of detecting plagiarism. This service is subject to the Terms and Conditions of Use posted on the Turnitin.com site.

You may forward your Cougar email account to another account; however, the College cannot be held responsible for breaches in security or service interruptions with other email providers.

Students should use email for private messages to the instructor and other students. The class discussions are for public messages so the class members can each see what others have to say about any given topic and respond.

Late Assignment Policy

An online class requires regular participation and a commitment to your instructor and your classmates to regularly engage in the reading, discussion and writing assignments. Although most of the online communication for this course is asynchronous, you must be able to commit to the schedule of work for the class for the next eight weeks. You must keep up with the schedule of reading and writing to successfully complete the class.

No late discussion posts will be accepted.

Zero points are given for any assignment turned in late.

Course Evaluation

You will have an opportunity to evaluate the course near the end of the session. A link will be sent to your CougarMail that will allow you to access the evaluation. Be assured that the evaluations are anonymous and that your instructor will not be able to see them until after final grades are submitted.

Proctor Policy

Students taking courses that require proctored exams must submit their completed proctor request forms to their instructors by the end of the second week of the session. Proctors located at Columbia College campuses are automatically approved. The use of ProctorU services is also automatically approved. The instructor of each course will consider any other choice of proctor for approval or denial. Additional proctor choices the instructor will consider include: public librarians, high school or college instructors, high school or college counseling services, commanding officers, education service officers, and other proctoring services. Personal friends, family members, athletic coaches and direct supervisors are not acceptable.
