Meeting Times
MATH 112 Section 10 meets Tu-Th  2:00 PM-3:15 PM in  LA5 room  245.

Office hours (held in my office:  FO3-218) 
Feel free to stop by, email or call to schedule an appointment or ask a question!

Tuesdays and Thursdays  3:15-4 and 4:30-5:30
Description:
Topics include: review of algebra; the real number line and the cartesian plane;  functions, including lines, quadratic functions, exponential functions and logarithmic functions; and modeling with functions and equations.

Goals: 
The goals for the mathematics content of College Algebra for science include:
  • to increase students' quantitative literacy.
  • to improve students abilities to explain quantitative concepts using words, tables and diagrams.
  • to improve students’ reasoning skills
  • to improve students’ communication skills in the languages of mathematics
  • to introduce students to spreadsheet software

Required Course Materials: 

Text:  College Algebra, by Stewart, Redlin and Watson.  4th Edition.
Attendance and participation:
(5% of your course grade)Attendance in class is required.  I will try not to be unreasonable about this, so if you need to miss a class, come talk to me about it.  At the least, all university rules on excused absences will be excused.

Assignments::

It is my philosophy that:
Teaching is not telling; listening is not learning.
This means that you can expect to spend time actively working on mathematics both in and out of class.  Homework assignments will serve two purposes:
  • Assignments will help students organize and internalize material discussed in class, to help students prepare for exams.  Understanding my explanation of the mathematics is very different from solving the problems yourself.  You must engage in mathematical activities yourself to really learn the concepts.
  • Assignments will allow me to assess students' knowledge of material that may not be covered on exams.  Homework assignments are not only busy work to help you prepare for test, they also allow me to assess your abilities to work with the material beyond what I can ask you to do in an in class exam. Notice that the homework is worth the same percentage of your grade as an exam.
(20% of your course grade) Hand-graded Homework
You can expect to write up a few of problems to be hand-graded each week.  In addition, you may have mini-quizzes from time to time (no surprises).    
    You can expect to write up a few problems to be hand-graded each week. These problems will almost always include answers that are not numbers or formulas. You may be asked to explain how you approach certain problems, or to explain something in words about what you are learning.  These assignments are like little take home tests: they are not drill to help you prepare for exams, rather they are a way I can see to what degree you have learned the material.  Note that the hand graded homework is worth the same amount as one midterm.
(15% of your course grade) Computer Projects
There will be four computer projects.

We will use Microsoft Excel to do projects related to each of the four sections of material.   Part of the purpose of these projects is to introduce students to using spreadsheets, though we will focus only on the aspects of spreadsheets that we need to study the material.  It is my hope that after using the spreadsheets in this fashion, you will gain enough facility with them to be able to figure out how to make a spreadsheet do anything that you may need later in life.  We will start each computer project together in a computer classroom. Students will be expected to complete the projects on their own, using their own computers, or using university labs.  All computers available for students to use through the university have the Microsoft Excel software.


Tentative Schedule:
Though the exam dates will not change, I may adjust the content to accommodate us if we need more time on a topic, or if we finish a topic ahead of schedule.
