MTH 60 is the first term of a two term sequence in beginning algebra. One major problem experienced by beginning algebra students is difficulty conducting
operations with fractions and negative numbers. It would be beneficial to incorporate these topics throughout the course, whenever possible, so that
students have ample exposure. Encourage them throughout the course to get better at performing operations with fractions and negative numbers, as it will
make a difference in this and future math courses.
Vocabulary is an important part of algebra. Instructors should make a point of using proper vocabulary throughout the course. Some of this vocabulary
should include, but not be limited to, inverses, identities, the commutative property, the associative property, the distributive property, equations,
expressions and equivalent equations.
The difference between expressions, equations, and inequalities needs to be emphasized throughout the course. A focus must be placed on helping students
understand that evaluating an expression, simplifying an expression, and solving an equation or inequality are distinct mathematical processes and that each
has its own set of rules, procedures, and outcomes.
Equivalence of expressions is always communicated using equal signs. Students need to be taught that when they simplify or evaluate an expression they are
not solving an equation despite the presence of equal signs.
Instructors should demonstrate that both sides of an equation need to be written on each line when solving an equation. An emphasis should be placed on
the fact that two equations are not equal to one another but they can be equivalent to one another.
The distinction between an equal sign and an approximately equal sign should be noted and students should be taught when it is appropriate to use one sign
or the other.
The manner in which one presents the steps to a problem is very important. We want all of our students to recognize this fact; thus the instructor needs to
emphasize the importance of writing mathematics properly and students need to be held accountable to the standard. When presenting their work, all
students in a MTH 60 course should consistently show appropriate steps using correct mathematical notation and appropriate forms of organization. All
axes on graphs should include scales and labels. A portion of the grade for any free response problem should be based on mathematical syntax.
There is a required notation addendum and required problem set supplement for this course. Both can be found at spot.pcc.edu/math.
