DEFINING LEARNER OUTCOMES FOR INTERMEDIATE ALGEBRA
The following learner outcomes for Intermediate Algebra
are classified into 3
categories.
These core outcomes represent the
fundamental concepts of
Intermediate algebra which students should be able to do at the end of this
course. Some
of these concepts are new to the students while others have been introduced in
elementary algebra and now require greater depth.
Students should have experience with these
outcomes in order to
begin developing familiarity with the ideas and confidence performing related
skills.
Indicators for these outcomes would be on midterms but not necessarily on the
final
exam.
These outcomes are optional. An instructor
may expect these of
students during the course but not in lieu of a C1 or C2 outcome.
