Questions about access to the online systems must be addressed to the instructor before the end of first week of classes.

4 4 B. Access to the Internet. It is expected that students have a reliable connection to the Internet. This course requires access to Enhanced WebAssign ( which will require a purchased Enhanced WebAssign access code. WebAssign is an online homework system. This homework system will require the student to have daily access to the Internet whether at home, the college, or some other location. An Enhanced WebAssign access code is required for the course. Once you have an access code, you can register for WebAssign by browsing to Click ENTER CLASS KEY button which is located right next to the LOG IN button on the top right hand corner and enter the Class Key: jalc in the three spaces provided. C. Calculators. A TI-83 or TI-84 graphing calculator is required for this course. D. Required Materials. The usual notebook, paper, pencils, Calculator etc., represents the required materials for the class E. Recommended Materials. The textbook, while not required, is highly recommended. But your access to the enhanced WebAssign will give you full access to an ebook. F. Homework. Homework will be assigned for each section of the text that is covered. The student should realize that, as a general rule of thumb, a minimum of two hours of study outside of class is required for every one hour of class time. This course will require between six and ten hours per week of outside class work if the student plans to successfully complete the course. G. Attendance. This is not a self-paced course. You must keep up with the deadlines given in the online course. You must be logged into Desire2Learn (D2L) and WebAssign several days per week for any new resources, announcements and to do homework. Student Success Center (Room C219). Services available for students include tutoring (both scheduled one-on-one tutoring and walk-in tutoring) and Disability Support Services. Students can drop in during the hours of operation for tutoring in the Math Help Room (C219 and C223) or the Biology Help Room (C243A). To receive one-onone tutoring, students should make a request early in the semester in the Student Success Center. The Student Success Center is also the place to arrange accommodations. John A. Logan College will make reasonable accommodations for students with documented disabilities. Contact the coordinator of Disability Support Services, Room C219B, ext. 8516, for more information. The coordinator must determine eligibility and arrange appropriate academic accommodations. However, it is the student s responsibility to register in advance of a school term with Disability Support Services and to turn in a class schedule each term to ensure accommodations are arranged. Free educational workshops are also provided by the Student Success Center throughout the semester. For more information, visit the Student Success Center website at

5 5 English Writing Center/Tutoring. For assistance with writing assignments in any college courses, students are encouraged to visit the Writing Center in C214. English instructors are available for one-on-one tutoring each semester during hours posted at the center. Financial Aid. Students who 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. Administrative Withdrawal. A student may be withdrawn from a class for lack of attendance/participation as defined below. Logging into an online course is not sufficient to be considered participation. Participation for online courses is defined as an active process and may include posting/sending assignments to the drop box or instructor s , participating in online discussion boards, taking quizzes or exams, or otherwise communicating and/or participating in some manner that is approved by the instructor. A student who has been administratively withdrawn from class will receive an notification from the Admissions Office. This notification will outline the student s appeal options if the student wishes to re-enroll in the course. Face-to-Face Class (8 or 16 weeks) Online Class (8 week) Online Class (16 week) Student may be withdrawn from class if the student has missed four (4) consecutive class periods without prior notification to the instructor of the absences. Student may be withdrawn from class if the student has not participated (as indicated by activity reports) in the online class for the equivalent of one week. Student may be withdrawn from class if the student has not participated (as indicated by activity reports) in the online class for the equivalent of two weeks. Safety Review Request. Our safety at JALC is everyone s responsibility! Faculty, staff, and students are encouraged to use the Safety Review Request, link on the JALC home page or contact Campus Safety directly (Ext or Room E105) to report safety concerns or questions. This statement comes from the John A. Logan College Campus Violence Prevention Committee. Math Help Room. Students are encouraged to visit the Math Help Room in C218 where free one-on-one tutoring is available during posted hours.

6 6 METHOD OF EVALUATION: Evaluation will be made on the basis of A. Graded Homework. There will be online homework assignments on WebAssign. The lowest five homework scores will be dropped. The remaining homework assignments will be 20% of the student s grade. These assignments will have due dates and it will not be extended. Failure to meet the deadlines will result in a zero on the assignment. B. Exams. There will be four proctored 100 point exams taken in the learning lab or at an approved testing site. The average of the exams will be 60% of the student s grade. Students will not be given any of the tests to take home. The only materials allowed during the exam will be a pencil and a calculator. A picture ID will be required to take the exams. If you cannot take the exams at John A. Logan College Learning Lab, contact me immediately before the end of the first week of classes to make arrangements for a testing site. Exam 1 Chapter 1 is due on or before June. 25 th Exam 2 Chapter 2 is due on or before July. 6 th Exam 3 Chapters 3 and 4 is due on or before July. 20 th Exam 4 Chapters 5 and 9 is due on or before July. 29 th C. Final Exam. A proctored 200-point comprehensive final exam which will include chapters 1, 2, 3, 4, 5, 9, and 10 will be given in the learning lab or at an approved testing site. Final exam must be taken on or before Aug 6th. All students are required to take the final exam. This final exam will be 20% of the student s grade. If a student scores a higher percentage than his/her lowest exam score, then the final exam score will also replace the lowest exam score. This will be possible only if the student has taken all scheduled exams that were given during the semester. Grading Scale. Your final course grade will be based on Homework 20% Exams 60% Final 20% A % B 80-89% C 70-79% D 60-69% E 0-59% D. Make-up Policy. Since students plan their exam dates and times, no make-ups will be given.

7 7 METHOD OF PRESENTATION: This course will be administered online through D2L and WebAssign. The student can obtain additional help through (1) school tutoring C218/219 (free), (2) DVD s keyed to each section of the textbook, available in the Learning Lab or (3) the instructor by appointment.
