Text:Functions and Change: A Modeling Approach to College Algebra – 4th Edition

By: Crauder, Evans, Noell

We will be covering the majority of chapters 1 – 5.

Materials:We will be making substantial use of the TI-84 (or 83) graphing calculator.

This calculator is required for all sections of 120.

Homework:There will be homework assigned for each section (see last page for details). The purpose of these exercises is to get you familiar with the material of the section and the type(s) of questions and ideas that I expect you to understand. Questions on quizzes and exams will be comparable to these problems. If you do not work on the homework, it will be reflected in your quiz and exam scores. Each class will begin with a little time devoted to homework questions.

Quizzes:There will be 6 bigquizzes throughout the semester (see course schedule for specifics). In general, quizzes cannot be made-up or rescheduled for any reason. Quizzes will focus mainly on the material most recently covered, however the nature of this particular course dictates that the quizzes are also somewhat cumulative.

Exams:There will be both a midterm exam and a final exam. See the class schedule for the dates of these. These exams will both be fully cumulative.

Philosophy:The overall goal in this course is to provide you with some understanding of the role of mathematics in modeling the real world. Our approach makes significant use of technology, and so the development of conceptual understanding is just as important if not more so than the mastery of exclusively algebraic skills. This course serves as a good preparation for calculus (150), but it will also provide you with mathematical skills that will be helpful regardless of whether or not you take calculus later.

Grades:Your final grade will be computed by counting the average of your quizzes as 50% of your grade, counting the midterm exam as 20% of your grade, and counting the final exam as 30% of your grade. The scale will be as follows:

A = 94 – 100D+= 68 – 69

A-= 91 – 93D= 64 – 67

B+= 88 – 90D-= 60 – 63

B = 84 – 87F= below 60

B-= 81 – 83

C+= 78 – 80

C = 74 – 77

C-= 70 – 73

I encourage all students to come and see me in my office or the Math Lab with any questions or concerns you are having with the course and the material. We will dedicate some class time to homework questions, but this time will be limited by what we must cover each class. Thus, to get the most time possible for homework and review questions, come and see me in the office/lab.

I also encourage everyone to make use of the Math Tutoring Lab. When I am not in the lab, there is an upper level Mathematics major/minor on duty who can assist you. It is in Conaton Learning Commons (CLC) 419. It is free to all Xavier students.

Do not fall behind on homework!!! Come and see me if you’re struggling. It is much easier to catch up on one night’s worth of material than it is a week’s worth. So as soon as you are struggling, come and see me about it.
