Grades:  A = 90% (810 pts), B = 80% (720 pts), C = 70% (630 pts), D = 60% (540 pts)

Quizzes:    We will have a short quiz almost every week. Each quiz will count for 15 points and the lowest quiz score will be dropped from your grade.

Exams:     There will be four in-class exams and one comprehensive final exam. Exam dates are tentative until officially announced in class. The final exam is scheduled for Wednesday, May 6, 6:00 – 8:00pm in Pasteur 133. Note: This is NOT the standard time for the final exam listed on the Registrar’s webpage.

Homework:    Homework will be assigned daily and will be due the day of the corresponding quiz at 7:30am (Or at 7:30am the day before an exam). All homework can be found on and must be submitted via the WebAssign website. You may request extensions on your homework, but no extension past an exam will be given. Most, but not all, questions on the quizzes and exams will be based on assigned homework and the “Suggested Quiz Preparation” questions.

WebAssign:    Your user name is your WSU email username and the institution is “winona”. The first time you login your password is your WSU Tech ID (including the beginning zeroes). You should change your password after the first login. More help can be found here. If you have any problems logging onto WebAssign or doing any of the homework assignments, please contact the instructor. Some good WebAssign Tips can be found below.

Extra Credit: Periodically extra credit homework assignments may be given. These points earned through extra homework go only toward homework points and only a maximum of 130 points total will be given for homework. Likewise, extra credit problems on quizzes apply only to the 135 points allocated for quizzes.

Assessment Participation:     This class will be part of a study to examine the effects of different homework arrangements on student success. Being a part of the study is optional. Participation and completion of the assessment surveys will enhance your grade by 35/35 points.

Technology:   Graphing calculators are not required. However, they are highly recommended, preferably a Texas Instrument. Most exams will be split into two sections: one with calculators allowed, and one without. You MAY NOT use your cell phone, laptop, PDA, or other device capable of electronic communication in place of a calculator. Contact the instructor if you are having difficulties obtaining a calculator.

Resources: The Mathematics Achievement Center (MAC) is located in Gildemeister 135. The MAC will be staffed with one or two tutors Monday through Thursday, 10am – 7pm.  The MAC will be open from 8am – 9pm, M-Th and open during the day on Friday for student use (even though tutors may not be present).  Wireless and wired access is available.

Late/Missed Work:   Late homework or missed quizzes will result in a score of zero. There are no make-up quizzes. Make-up exams will be given at the discretion of the instructor. If you miss class, it is your responsibility to obtain notes and assignments from fellow students. If you have an unavoidable absence, please inform the instructor beforehand.

Academic Dishonesty:  Any type of academic dishonesty (cheating, copying, etc.) will result in failure and will be reported to school authorities. If you are having trouble with an assignment, please see the instructor first.

Note:   This syllabus is subject to change if deemed necessary by the instructor.

Welcome to college math!

 

If this is your first math class taken in college, there are some important things you need to know. College math classes are run very differently from high school math classes. On the surface it may seem they are similar as you listen to the lecture and take notes, but there are significant underlying differences. Knowing these ahead of time can help you make the most of this coming semester.

 

#1: College math classes generally stay on the schedule in the syllabus. If there is one day allotted to the topic that is probably all of the class time that will be spent on it, even if “most” of the students “don’t get it.”

 

#2: It is expected that you will read the text and do the problems in order to learn the material, even if no one checks up on you. The instructor might never collect the homework, but that doesn’t mean it doesn’t affect your grade.

 

#3: You will sometimes be responsible for material in the textbook that is not covered in class. If there is a text reading and/or homework problems covering a concept that was not discussed in class, you are still expected to learn it. If you don’t understand it, make an appointment with your instructor for help.

 

#4: Some material is covered only in class, is not in the textbook, and may not have any homework problems on it. If you miss class, you may miss content that you are responsible to know. If you have an unavoidable absence, be sure to get the notes and any announcements from a classmate.

 

#5: There will be test questions that don’t look “just like the homework.” In college, you are expected to focus on learning the concepts, not just memorizing how to do certain types of problems. These concepts can – and will – appear in very different forms on tests and quizzes.

 

#6: At times you will be expected to be able to explain why a problem is done a certain way in addition to being expected to do the problem. As you work on problems in class and on homework, don’t be satisfied with getting the correct answer; ask yourself why that method is logical, and how you could explain that logic to someone else.

 

#7: Most importantly, you are responsible for your own learning. If you attend class faithfully, get the notes and announcements if you have an unavoidable absence, read the text, do the homework and question yourself (as in #6), and still don’t understand something, it is up to you to get the extra help you need. Visit the instructor during office hours or make a special appointment to ask questions, form a study group, etc. There are many resources and people willing and happy to help, but you need to take the initiative and seek out the help you need.

 

Good luck on a happy and successful semester!

 

WebAssign Tips

 

#1: Use the Mozilla Firefox browser. The flash applications in WebAssign cause Microsoft Internet Explorer to lock up, thus losing all of your work from that session. If you need help installing Firefox, click here or contact the instructor.

 

#2: Do not try to sit down at a computer and just do your homework on Webassign. Print off the problems and work through them in a notebook first. When you have completed the assignment on paper, then go back and enter your answers into WebAssign. This way you will have a good paper record to study from, to examine for errors if WebAssign marks something incorrect, and to show to a tutor or the instructor when getting help.

 

#3: Do not wait until the night before the assignment (or collection of assignments) is due to do it. If you lose your internet connection or experience technical problems, you will not be able to hand in the assignment on time. Some WebAssigns are short (3 – 4 problems) and some can be quite long (11 – 12 problems). Make sure you leave yourself enough time to take full advantage of the multiple attempts.

 

#4: WebAssign will only accept the 100% correct answer. So you will not likely be able to guess the answer. At the same time, if you have almost the right answer, but you’re missing something small like a minus sign, WebAssign will still mark it incorrect without any hint of how close you are to the correct answer. Also, WebAssign can be very particular about how you enter an answer. For all these reasons it is important that you are careful about how you work out the problem and report the solution. This is, in general, an important lesson to learn.

 

#5: Don’t use any method on WebAssign that won’t work on an exam. For example, many questions on WebAssign will be presented as multiple choice and you can “solve” it by checking each option. However, on a quiz or exam the same question will probably not be multiple choice, so you need to know how to find the correct answer from scratch. If you don’t know how to do an assignment without “shortcuts”, ask a fellow student, a tutor, or the instructor.

 

#6: After the due date has passed, go back and look at the solutions for the problems you missed. Often there will be a link to a pdf file with a detailed solution to the problem. If you still can’t understand the solution, ask a fellow student, a tutor, or the instructor to help you.

 

 

This course can be used to satisfy the University Studies requirements for Basic Skills in Mathematics.  This course includes requirements and learning activities that promote students’ abilities to…

a.         use logical reasoning by studying mathematical patterns and relationships;

Math 120 includes functional notation and identifies and uses the combination of functions, such as sums, products and compositions. Formulas are written that involve variation.

Understanding the relation between exponential and logarithmic functions and the simplification of expressions using the trigonometric identities are covered.

 

b.         use mathematical models to describe real-world phenomena and to solve real-world problems - as well as understand the limitations of models in making predictions and drawing conclusions;

Linear models for bivariate functions, exponential models for growth or decay, and periodic models with trigonometric functions are differentiated, studied and used. Properties of trigonometric quantities are examined by the use of the unit circle.  

 

c.         organize data, communicate the essential features of the data, and interpret the data in a meaningful way;

The domain and range of a function are found and functional notation is used to show the relation between variables. The average rate of change is calculated from a graph, a function or a table.

 

d.          express the relationships illustrated in graphical displays and tables clearly and correctly in words;

The student is able to express solution sets correctly with a number line graph by using interval notation and inequalities. Students identify and express the characteristics of the graphs of powers, polynomials, rational functions, exponential, and trigonometric functions.

This includes increasing/ decreasing intervals, curvature, local optima, long-term behavior of functions when given a function, a formula, or a graph.  Explanations of how transformations change the characteristics of a function and graphing the transformed function are done.

 

Commitment to Inclusive Excellence:  WSU recognizes that our individual differences can deepen our understanding of one another and the world around us, rather than divide us. In this class, people of all ethnicities, genders, religions, ages, sexual orientations, disabilities, socioeconomic backgrounds, regions, and nationalities are strongly encouraged to share their rich array of perspectives and experiences.  If you feel your differences may in some way isolate you from WSU’s community or if you have a need of any specific accommodations, please speak with the instructor early in the semester about your concerns and what we can do together to help you become an active and engaged member of our class and community.
