In this class you will: Investigate mathematical ideas on your own and together with others Read and interpret various representations of mathematical ideas Justify your thinking, reasoning, and answers Communicate your ideas in a clear and organized way using precise mathematical vocabulary and symbolism Reflect thoughtfully on your work in order to deepen your understanding Required Course Materials: Textbook: Algebra and Trigonometry with Algebraic Reasoning Activities Manual (Rockswold, OSU Custom Edition). This textbook and accompanying MyMathLab access code will be used for both MTH 103 and MTH 111. MyMathLab access code (CODE CAN BE REUSED, BY YOU, FOR FREE, IN MATH 111) Clicker (audience response system) Scientific calculator Notebook to organize in-class work and assignments throughout the term Course Design: During class you will sit and work with an assigned group. Group assignments will change throughout the term. You need to take notes during all instructor lecture and group work times and organize these notes in a notebook. You will need to use the notes for reference during future classes and to study for the quizzes and tests. You must bring to class each day: Print outs of activity worksheets and lecture handouts. Textbook Clicker Calculator Each day of class will include a combination of any or all of the following: Group work on activities and various problems covering the course concepts and skills Whole-class discussions Short lectures by your instructor Student presentations to the class of your reasoning and solutions Clicker questions

3 Getting help outside of class: Math Learning Center (MLC) is located in Kidder Hall 108 and open Monday through Thursday from 9:00 to 5:00, and Friday 9:00 to 4:00 for free drop-in help from a variety of tutors, during weeks 2 through 10 each term. CLC on the first floor of Valley Library also has free drop-in math tutoring Sunday through Thursday 7-10 PM, during weeks 2 through 10 each term Resources for academic success: Your instructor s office hours will be posted on the web page no appointment required during scheduled hours. Students With Disabilities: Accommodations are collaborative efforts between students, faculty and Disability Access Services (DAS). Students with accommodations approved through DAS are responsible for contacting the faculty member in charge of the course prior to or during the first week of the term to discuss accommodations. Students who believe they are eligible for accommodations but who have not yet obtained approval through DAS should contact DAS immediately at Academic Honesty and Student Conduct: Students are expected to be familiar with the Homework and Exam policies stated in this syllabus, as well as Oregon State University's Student Conduct Code. Classroom Behavior and Academic Honesty Policy: It is good to discuss homework problems with classmates, making sure that you each work until you understand the material and can explain it completely to another person. Homework submitted online must be your own work. If I find that you have copied the work of another person on any quiz or test, you will receive a score of zero for that assignment and it will be reported according to university policy. Grading System 1. Homework assignments: 75 points (overall percent earned on homework will be multiplied by 75 to determine your homework points for the term) Online homework is completed at My Math Lab There will be 2 assignments each week, with a new assignment opening after each class period. Each assignment remains open for a week. Your instructor may also assign other types of homework in addition to the online homework 2. Clicker questions and other in-class work: 75 points (overall percent earned on clicker questions/in-class work will be multiplied by 75 to determine your clicker points for the term) There will be questions at the beginning, end, and/or during class most days, which will be answered using a clicker. Clickers (audience response system) are purchased at the bookstore and will be used in many of your classes at OSU. For each clicker question, you will earn half credit for participating (clicking a response) and full credit for a correct response. Your instructor may also sometimes have other types of graded in-class work in addition to clicker questions. You need to register your clicker in Blackboard before the 2 nd day of class.
4 3. Quizzes: 50 points each There will be two quizzes in class. Quiz 1 will be taken the first day of class during week 4 (Monday or Tuesday, depending on your class section). Quiz 2 will be taken the first day of class during week 9. Each quiz is worth 50 points, for a total of 100 quiz points possible. You will be allowed to use a scientific calculator during the quizzes. [No graphing calculators and no cell phone calculators are allowed during quizzes or tests.] 4. Exams: Midterm Exam 100 points, Final Exam 150 points There will be one evening midterm exam and a comprehensive final exam. The exam rooms and policies will be announced in class and online before each test. Alternate exam times must be requested from your instructor at least 2 weeks in advance in the case of a verified, qualifying conflict with the midterm or final exam time. If you request an alternate exam time, your instructor will determine whether or not your request meets the requirements of the OSU exam conflict policies. There are no late exams. Each exam will contain some written work problems requiring you to write detailed explanations and show all steps of the work, and will also contain some short answer problems for which only your final answer will be graded. The midterm exam is held outside of class on Tuesday evening, May 5 7:00-8:20 PM, room location to be announced. The final exam time is Wednesday morning, June 10, 7:30 9:20 AM, room location to be announced (Final exam times are assigned by the registrar and the exam must be taken at the scheduled time, except in the case in which you have two exams assigned the exact same time.) The procedure used to calculate your course grade is as follows: Course Point Total Calculation Category Course Points Possible Homework: (percent earned times 75) 75 points Clicker/inclass work (percent earned times 75) 75 points Quizzes: (50 points each) 100 points Midterm Exam: 100 points Final Exam: 150 points Total Course Points Possible: 500 points Final Letter Grade Assignments A Course Points B Course Points C Course Points D Course Points F below 298 Course Points +/- grades may be assigned at the discretion of your instructor
