# Introductory Algebra I Lecture

## COURSE DESCRIPTIVE GUIDE

**COURSE DESCRIPTION**

This is a lecture course in elementary algebra. Topics include the real number
system, operations with real numbers,

simplification of algebraic expressions, solving linear equations and
inequalities. Topics also include graphing

linear equations, slopes, equations of lines, graphing inequalities in two
variables, systems of linear equations,

applications and problem solving. Additional topics are exponents, scientific
notation, and operations with

polynomials.

**This is a developmental course and students must achieve a grade of C- or
better to pass the course. Credit
for this course will not be counted toward fulfilling graduation requirements at
STCC.**

**ATTENDANCE**

Attendance is required. A student having three absences coupled with
unacceptable progress risks withdrawal from

this course. A student absent from class bears full responsibility for all
subject and procedural information

discussed in class, including any changes in exam dates and assignments.

**TESTING AND GRADIN**G

The final grade will be based 40% on the quiz average and 60% on the examination
average. **Students must
achieve a minimum overall average of 70% in this course in order to pass.
Students must also score at least
70% on the final examination in order to pass this course and progress to
Algebra 2.**

If at any time during the semester there is any evidence of academic
dishonesty or collusion by students on an exam

or quiz, the Dean of Students and other relevant college authorities will be
notified, and students involved may be

dismissed from the course with an automatic grade of F.

**INDIVIDUAL HELP**

The instructor will meet with students during scheduled office hours. To insure
the availability of the instructor,

please make an appointment. The Tutor Center in the Math Department (through
Room 425) is open from 8:00AM

to 3:00PM Monday through Friday. Students may drop in at any time to work with
student tutors. Professional

tutors are available in the Student Success Center by appointment.

**SPECIAL NEEDS**

Students with special needs that require accommodations must contact the Office
of Disability Services for

processing of the necessary documentation, and then speak to the instructor

**STCC POLICY ON DISRUPTIVE BEHAVIOR**

Behavior, which disrupts the establishment or maintenance of the learning
environment, may result in the student

causing the behavior to be excluded from the classroom by the instructor. The
student may be subject to further

punitive action by the Dean of Students.

Late arrival and early departure from class is considered disruptive
behavior. Students are expected to arrive on

time for class, and to seek permission from the instructor if they need to leave
class early.
