Quantitative Reasoning
Competence Offered |
L-6 Can use mathematical symbols, concepts and methods to describe and solve problems . |
Credit Hours: 4 Quarter Hours
Course Description
This course will cover basic algebraic and statistical concepts. Students will
learn computational skills
ranging from basic variable representation and use of formulas to data
organization and graphing. The
basic skills needed for comprehension will be reviewed as each new concept is
introduced. Scientific
calculators and the Excel spreadsheet program will be used as tools for
exploring algebraic and statistical
concepts. Quantitative reasoning will be a large part of the class discussion.
Specific Learning Outcomes:
1. Understands the symbolic system presented in algebraic equations so that
indicated relationships
have an attainable meaning.
2. Can perform basic algebraic operations including manipulating algebraic
formulas and equations.
3. Can organize data and perform basic statistical calculations.
4. Has ability and confidence to think deductively and numerically about
relationships among
operations, numbers and variables .
•By the end of this class, students will be able to:
•Use the basic algebraic properties.
•Use problem-solving techniques.
•Use and manipulate percentages.
•Solve linear equations.
•Use and manipulate formulas.
•Use a calculator to evaluate formulas.
•Create and organize data sets.
•Interpret and produce meaningful graphs and charts .
Evaluation & Grade Policy: Grades are based on quizzes, homework and class
participation.
Quizzes | Homework Sets | Other |
5 @ 20 pts each Total Points: 100 |
4 @ 40 pts each Total Points: 160 |
Class Participation @ 20 points 1 Lab @ 60 pts. 1 paper @ 30 pts. Total Points: 110 |
Total Points Possible: 370 (Also see 10 Week Plan)
Grading Scale | |
90% - 100 % | A |
80% - 89 % | B |
70% - 79 % | C |
60% - 69% | D |
Less than 60% | F |
Any grade lower than C- is unacceptable for the SNL
program. Students can opt for a Pass/Fail grade but
must earn a 70% or higher to receive the passing grade. A passing grade does not
factor into a students
GPA but a failing grade does.
Attendance:
Attendance is important and mandatory. Students must be in class to take the
quizzes.
They cannot be made up. Missing more than two classes (or 6 hours of class time)
will
adversely affect a student’s grade and can result in a Failing Grade for the
quarter.
Textbook: There is a required text for this class (see below). Additional
notes and
worksheets for each unit may be available on the class website on Blackboard.
