4 4 COURSE REQUIREMENTS: 1. Access to Online System. Being an online course, students must have access to the online system being used for the course. This course requires access to the textbook publisher s homework system called MyStatLab. ( I will refer to this system as MyStatLab. a. Accounts for MyStatLab are part of the textbook requirement. If you do not have a MyStatLab registration code as part of your textbook, you will need to purchase one separately. This is a requirement for the course. Once you have a student access code for your MyStatLab student access kit, you can register for MyStatLab by browsing to and using the course ID: dethrow b. Questions about access to the online system must be addressed to the instructor as soon as possible. 2. Access to the Internet. It is expected that students have a reliable connection to the Internet. It is also expected that students have a backup plan in order to connect when the primary connection fails. Such backup plans may involve visits to a friend s house, family member s house, JALC computer lab, library, or other publicly available computers. Students with laptops and wireless network cards may access MyStatLab from public WiFi areas. 3. Valid Accounts. You must have a valid account to participate in this course. It is required when you register for MyStatLab. 4. Calculators. The Texas Instruments TI-83 or TI-84 calculator will be required to work some problems in this course. They will be allowed on all homework and assignments, quizzes, and proctored exams. Other calculators are subject to approval from the instructor. 5. Attendance. This is not a self-paced course. You must keep up with deadlines as given in the online course. You must be logged into and participating in MyStatLab at least 3 days per week. In reality, you will likely need to be logged in and participating in course activities every day in order to be successful in the course. It is expected that you will be devoting a minimum of 12 hours per week on this course alone. Student Support Services: Tutors may be obtained through the Student Success Center. Contact the staff in C219 if this service is desired. John A. Logan College will make reasonable accommodations for students with documented disabilities under section 504 of the Rehabilitation Act of 1973, and the Americans with Disabilities Act of Any student with a disability that may have some impact on work in this class, who feels she/he needs an accommodation, should make an appointment with the Coordinator of Services for Students with Disabilities on this campus, Kristin Shelby,

5 5 Room C219B, Ext Before services can be provided, this advisor must determine eligibility and arrange appropriate academic adjustments. It is the student s responsibility to register in advance of a school term with this office and to turn in a class schedule each term to ensure that there is every opportunity for success in this class. English Writing Center/Tutoring: For assistance with writing assignments in any college course, students are encouraged to visit The Write Place in E109. English instructors are available for one-on-one tutoring each semester during hours posted at the center. Financial Aid: Students that receive financial assistance and completely withdraw from classes prior to 60% of the semester being completed (approximately 2 3 weeks after midterm) could be responsible to return a portion of their Federal Pell Grant award. Prior to withdrawing from courses, students should contact the Financial Aid Office. Course Withdrawal Information: It is expected that you will attend this class regularly. If you stop attending for any reason, you should contact your advisor and withdraw officially to avoid the posting of a failing grade (an E) to your transcript. It is also advisable to discuss the situation with your instructor before dropping. METHOD OF EVALUATION: 1. Online Homework. The homework will be online math problems in MyStatLab. a. The online math problems will be assigned for each section covered in the textbook. These problems must be completed using MyStatLab. While online, you have quick access to sample problems, guided solutions, some video and animation, as well as a way to ask me questions. You may also print out the assignment, complete it offline, log back into MyStatLab, and type in your answers. There will be deadlines for these assignments. Failure to meet the deadline will result in a zero on the assignment. There will be approximately 47 online math assignments worth 5 points each. Five activities will be dropped when calculating the course grade. b. I strongly encourage you to keep a notebook for your homework. Work every problem out in that notebook as if you were going to turn your notebook in for grading. Being organized on this will help prepare you for your proctored, written exams. 2. Online Quizzes. There will be approximately 10 quizzes during the semester. These quizzes will typically cover a chapter s worth of material. You will have some access to resources while working the quizzes, although there will not be as many as the Online Homework. There will be deadlines for quizzes. Failure to meet the deadline will result in a zero on the quiz. There will be approximately 10 quizzes worth 10 points each. Two quizzes will be dropped when calculating the course grade.

6 6 3. Proctored, Written Exams. There will be 3 proctored, written exams during the semester. These exams will cover multiple chapters and may cover topics from previous written exams. The only materials allowed during the exam will be a pencil and a calculator. The exams will be available in the Learning Lab on the John A. Logan College Carterville campus. A picture ID will be required to take the exams. If you are not in the southern Illinois area, it is your responsibility to contact the instructor during the first week of class in order to find an acceptable proctor. There will be deadlines for the exams. Failure to meet the deadline will result in a zero on the exam. These exams will be worth 300 points each. No points will be dropped from the exam grades. 4. Grades. a. Semester point break-down Graded Activity Maximum Points Online Math Problems 210 Quizzes 80 Proctored, Written Exams 900 Total Points in the Semester 1190 b. Grading Scale Grade Point Range A B C D E Class Conduct and Academic Dishonesty 1. Class Conduct. In general, if you follow the Golden Rule (treat others as you would like to be treated), you will not be confronted about inappropriate conduct. This applies to behavior while participating in online forum posts, correspondence, and instant messaging. Unacceptable behavior or conduct including (but not limited to) racist, sexist or derogatory remarks, foul language, inflammatory comments, condescending or rude remarks, flaming, or display of pornographic material will result in disciplinary action which may range from an E in the class to expulsion from the College. All incidents will be documented and kept on file in the department. Keep in mind that all correspondence in the course is viewable by me. At my discretion, I may remove material from public viewing.

7 7 2. Academic Dishonesty. a. Definition: It is expected that all submitted assignments are the submitter s original, independent work. Following is a list of situations that will be classified as academic dishonesty. Submitting any part of someone else s homework as your own. Allowing someone to submit any part of your homework as his or her own. Posing as someone else in the online environment. Getting help from someone else to complete online assignments. Using notes of any kind (e.g., cheat sheets, text typed in as a program on a calculator, writing on clothing or body parts, using cell phones or other communication devices, etc.) while taking a written exam. Looking at anyone s written exam during the exam. Allowing someone to look at your written exam during the exam. b. Consequences: Penalties for violating this policy on academic dishonesty may range from a zero on the assignment to an E for the course. The violation will be documented and kept on file in the department. I will be obliged to report the incident to the vice president for administration in accordance with Article IV, Section 2 found in Rights & Responsibilities A Student Code of Conduct. The College may then take additional action such as expulsion, suspension, probation, or reprimand by the vice president for administration. METHOD OF PRESENTATION: This course will be administered online. Videos, tutorials, and help will be provided through MyStatLab. The student can obtain additional help through (1) school tutoring (free) or (2) the instructor during a scheduled office appointment. The instructor will respond to relevant student initiated communication within a 48 hour period. TEXT: Elementary Statistics a la carte plus MyStatLab, 11 th Edition; by Mario F.
