### Short-term illness Policy

“If you experience flu symptoms such as fever, a cough, sore throat, body aches, headache, chills or fatigue, please don't come to class. If your symptoms persist, please ask your parents to take you home or to seek assistance from Student Health Services so that you can be cared for in a setting that does not put others at risk.”

Please notify me through email (boczko@ohio.edu) so that attendance as well as grading policy may be adjusted.

### Syllabus

**Prerequisites: **PL1 or C or T or better in Math D004 Intermediate Algebra with Pre-Algebra or D005 Intermediate Algebra.

**Textbook (Required): College Algebra 2nd Edition**, by Miller and Gerken. McGraw Hill. **ISBN 978-1-259-57046-9**.

An e-book version comes standard with the software package **ALEKS** that we use in the course. Students do not need to purchase a hardcopy textbook unless they wish to.

**Software**: Students will need to use the

**ALEKS 360**software to complete the course. Students should check their Blackboard for the course code. The course materials are offered as inclusive access. Students can opt out if they wish. College credit plus students need to speak with their high school program administrators and contact the bookstore.

**Material Covered:**The purpose of Math 1200 is to refresh college algebra skills required to move on to Calculus, Statistics, and Psychology.

**Learning Objectives:** Develop mathematical thinking and communication skills; increase quantitative and logical reasoning abilities needed for informed citizenship and in the workplace; strengthen quantitative and mathematical abilities that will be useful in the study of other disciplines.

**Attendance/Class Participation: **Attendance on a regular basis is vital to your success in the course. The work done in class will help you succeed in the course and earn a better grade. Homework may be collected and quizzes given at the discretion of the instructor. Attendance and participation in class will improve your understanding of the material. Please note that calculators or cell phones are not to be used during class/exam.

**Grade Scheme: Weights: **

**Top 3 hourly exams (out of 4) **100 points each = 300 points

**Quizzes, groupwork, written homework, attendance **40 points = 40 points

** Math Homework **60 points = 60 points

**Final exam 150 points = **150 points

**Total points 550 points**

**Grading Scale:**

**A**90% and above**A-**85%-89.9%**B+**80%-84.9%**B**75%-79.9%**B-**70%-74.9%**C+**65%-69.9%**C**60%-64.9%**C-**55%-59.9%**D+**50%-54.9%**D**45%-49.9%**D-**40%-44.9%**F**Below 40

**Makeup exams are not allowed unless there is an extenuating circumstance. **Keeping this policy in mind, only the three hourly exams (out of 4) along with the quizzes, homework, and the final exam will be used to determine your grade according to the grade scheme and grade scale given above. Students missing an exam due to a **university excused absence** (e.g., student athletes) will be offered make-up exam(s); **documentation must be provided** to show that the exam was missed due to a university excused absence.

**Final exam COMBINED-SECTION EXAMINATION**, TBA. Please note that *Final exam rooms **may or may not be the same as your classrooms. *

**Help Sessions:** SI sessions as well as math tutoring will be provided free of cost on certain evenings as well as during the day. These sessions will be announced. For more info, visit the Academic Achievement Center.

**For info on Supplemental Instruction** visit www.ohio.edu/si.

**Academic Misconduct:** Proper classroom decorum should be observed. Failure to do so will result in removal from theclass. Any cheating on exams will result in failure in the class and be reported to the Office of Community Standards and Student Responsibility, which may impose additional sanctions. You may appeal any sanctions through the grade appeal process. For more details, visit the university's Office of Community Standards and Student Responsibility page.

**Special Needs:** If you have specific physical, psychiatric, or learning disabilities and require accommodations, please let me know as soon as possible so that your learning needs may be appropriately met. Don’t forget to register with the Office of Student Accessibility Services to obtain written documentation and to learn about the resources they have available.
