Portland Community College | Portland, Oregon

Upon completion of the course students should be able to

• Use a graphing calculator and an Excel style spreadsheet system to perform calculations and create graphical displays.

• Make reasonable conclusions based upon data or situations modeled by a normal distribution.

• Construct, model and problem solve with linear and non-linear functions.

• Apply an understanding of functions and function notation.

• Recognize the difference between direct and indirect variation.

This class is designed around a group work and discussion classroom format.  The focus of the activities are reality based problems and situations from which formal definitions and procedures will arise.  A technology component is included as part of the course activities.
 

Assessment shall include:

1. At least two proctored, closed-book, no student-note exams (An instructor-provided sheet containing steps for using the TI-84 is allowed; see Addendum A via the following link:  http://spot.pcc.edu/math/addenda/mth98addendum.pdf).  One of the exams must be a comprehensive final exam that is worth at least 25% of the overall grade.   These exams must consist of primarily free response questions.
2. Group work and class participation
3. Homework including each of the following:
   1. Technology assignments
