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.
