There are 8 Modules for this course. Each Module consists of readings from the textbook or eTextbook, one homework assignment in MyLab Math (MML), leading up to one or two practice quizzes. Email your instructor with any questions on the homework assignments. There are instructor hints on the homework problems as well as "show me an example" student aids. Some Modules are longer than others and take two weeks. For example, Module 1 takes two weeks, whereas Module 2 takes only one week. Pay attention to the deadlines on MyMathLab homepage. Modules 1 - 4 will precede the Midterm Exam. Modules 5 - 8 will culminate with the comprehensive Final Exam.

Homework, Quizzes, and Exams will be done in MyLab Math (MML), which can be accessed via the MML links in the modules.

**Homework:** There will be 8 MML homework assignments, one for each of the 8 modules. Students will have 1 or 2 weeks to work on the homework assignments. Pay close attention to deadlines. Each homework problem can be attempted 3 times.

**Practice Quizzes:** There will be one or two MML practice quizzes for each module. For example, in Module 1 there will be two practice quizzes to complete. These are timed quizzes. Each quiz lasts for one hour and you have one attempt to answer each quiz question. However, you can start the quiz at your convenience during the week it is available. Plan out a quiet hour to work on a quiz. The quizzes are open book and open notes, but you may not leave the quiz screen during this hour. There will be a total of 12 practice quizzes.

**Exams:** There will also be a midterm exam and a final exam, both are in MyLab MATH (MML). Both exams must be taken at a testing center with a proctor. I recommend taking the exams at the testing center of your local college. Schedule these in advance. The exams will be given online, but you must show your work on scratch paper and turn in that to your proctors. The exams are closed book and closed notes, but you may use a calculator. The final exam is comprehensive.

Homework, quizzes, and exams must be completed during the scheduled week. There are no make-ups or do-overs.

Course Ground Rules

*The following two statements (1., 2.) were derived from the TBR System-wide Student Rules document, released January 2012: *

RULES OF THE TENNESSEE BOARD OF REGENTS STATE UNIVERSITY AND COMMUNITY COLLEGE SYSTEM OF TENNESSEE SYSTEMWIDE STUDENT RULES CHAPTER 0240-02-03 STUDENT CONDUCT AND DISCIPLINARY SANCTIONS

**Read the document in its entirety here.**

**1. Standards of Conduct:**

- Students are required to adhere to the same professional, legal and ethical standards of conduct online as on campus. In addition, students should conform to generally accepted standards of "netiquette" while sending e-mail, posting comments to the discussion board, and while participating in other means of communicating online. Specifically, students should refrain from inappropriate and/or offensive language, comments and actions.

**2. Review the TN eCampus Academic Integrity/Academic Honesty Policy:**

- In their academic activities, students are expected to maintain high standards of honesty and integrity. Academic dishonesty is prohibited.

Such conduct includes, but is not limited to:

- an attempt by one or more students to use unauthorized information in the taking of an exam
- to submit as one's own work, themes, reports, drawings, laboratory notes, computer programs, or other products prepared by another person,
- or to knowingly assist another student in obtaining or using unauthorized materials.

Plagiarism, cheating, and other forms of academic dishonesty are prohibited.

Students guilty of academic misconduct, either directly or indirectly through participation or assistance, are subject to disciplinary action through the regular procedures of the student’s home institution. Refer to the student handbook provided by your home institution to review the student conduct policy.

In addition to other possible disciplinary sanctions that may be imposed, the instructor has the authority to assign an "F" or zero for an activity or to assign an "F" for the course.

**Other Course Rules:**

Students are expected to:

- Participate in all aspects of the course
- Communicate with other students
- Learn how to navigate in Brightspace
- Keep abreast of course announcements
- Use the assigned course management (Brightspace) email address rather than a personal email address
- Address technical problems immediately:
- Observe course netiquette at all times.

Guidelines for Communications

**Email:**

- Always include a subject line.
- Remember without facial expressions some comments may be taken the wrong way. Be careful in wording your emails. Use of emoticons might be helpful in some cases.
- Use standard fonts.
- Do not send large attachments without permission.
- Special formatting such as centering, audio messages, tables, html, etc. should be avoided unless necessary to complete an assignment or other communication.
- Respect the privacy of other class members

**Discussions:**

- Review the discussion threads thoroughly before entering the discussion. Be a lurker then a discussant.
- Try to maintain threads by using the "Reply" button rather starting a new topic.
- Do not make insulting or inflammatory statements to other members of the discussion group. Be respectful of other’s ideas.
- Be patient and read the comments of other group members thoroughly before entering your remarks.
- Be cooperative with group leaders in completing assigned tasks.
- Be positive and constructive in group discussions.
- Respond in a thoughtful and timely manner.

Library

The Tennessee Virtual Library is available to all students enrolled in TN eCampus programs and courses. Links to library materials (such as electronic journals, databases, interlibrary loans, digital reserves, dictionaries, encyclopedias, maps, and librarian support) and Internet resources needed by learners to complete online assignments and as background reading will be included within the course modules. To access the Virtual Library, go to the course homepage and select the * Virtual Library* link under Course Resources.

Students with Disabilities

Qualified students with disabilities will be provided reasonable and necessary academic accommodations if determined eligible by the appropriate disability services staff at their home institution. Prior to granting disability accommodations in this course, the instructor must receive written verification of a student's eligibility for specific accommodations from the disability services staff at the home institution. It is the student's responsibility to initiate contact with their home institution's disability services staff and to follow the established procedures for having the accommodation notice sent to the instructor.

Syllabus Changes

The instructor reserves the right to make changes as necessary to this syllabus. If changes are necessitated during the term of the course, the instructor will immediately notify students of such changes both by individual email communication and posting both notification and nature of change(s) on the course bulletin board.
