Catalog Description
This course is a functional approach to algebra that incorporates the use of appropriate technology. Emphasis will be placed on the study of functions, and their graphs, inequalities, and linear, quadratic, piece-wise defined, rational, polynomial, exponential, and logarithmic functions. Appropriate applications will be included.

Expected Educational Results

General Education Outcomes
1.   This course addresses the general education outcome relating to communication
by providing additional support as follows:
a.   Students improve their listening skills by taking part in general class discussions and in small group activities.
b.   Students improve their reading skills by reading and discussing the text and other materials. Reading mathematics requires skills somewhat different from those used in reading materials for other courses, and these are discussed in class.
c.   Unit tests, examinations, and other assignments provide opportunities for
students to practice and improve mathematical writing skills. Mathematics
has a specialized vocabulary that students are expected to use correctly.
II. This course addresses the general education outcome of demonstrating effective
individual and group problem-solving and critical skills as follows:
A. Students must apply mathematical concepts to non-template problems and
situations.
B. In applications, students must analyze problems, often through the use
of multiple representations, develop or select an appropriate mathematical
model, utilize the model, and interpret results.
III. This course addresses the general education outcome of using mathematical concepts to interpret, understand, and communicate quantitative data as follows:
A. Students must demonstrate proficiency in problem solving including
applications of linear, quadratic, exponential, and logarithmic functions.
B. Students must be familiar with simple data analysis tools for building
linear and non-linear models.
IV. This course addresses the general education outcome of organizing information
through the use of computer software packages as follows:
A. Students are required to use a graphing calculator to graph functions, determine intercepts, and determine turning points of graphs.
B. Students will use simple data analysis tools for building linear and non-linear models.

Assessment of Outcome Objectives
ASSESSMENT OF EXPECTED EDUCATIONAL RESULTS

A. COURSE GRADE

The course grade will be determined by the individual instructor using a variety of evaluation methods. A portion of the course grade will be determined through the use of frequent assessment using such means as tests, quizzes, projects, or homework as developed by the instructor. Some of these methods will require the student to demonstrate ability in problem solving and critical thinking as evidenced by explaining
and interpreting solutions. A portion of the evaluation process will require the student to demonstrate skill in writing both correct prose and correct mathematics.

B. DEPARTMENTAL ASSESSMENT

This course will be assessed every three years.  The next assessment will occur during spring semester, 2005.  The assessment instrument will be administered as a portion of the final exam and will be administered in all sections of the course.  The instrument will consist of ten to fifteen multiple-choice questions.  Each of the eight course content areas and each of the General Education Outcomes addressed by the course will be measured by at least one exam question.

C. USE OF ASSESSMENT FINDINGS

The Math 1111 committee, or a special assessment committee appointed by the Academic Group, will analyze the results of the assessment and determine implications for curriculum changes.  An item analysis will be done for each exam question.  If the mean success rate on any assessment item is below 60%, the committee will make a recommendation to address the area of weakness.  The committee will prepare a report for the Academic Group summarizing its finding.
