General Description

These objectives are based on a course redesign developed at Northwest Missouri State University. The book used is Elementary and Intermediate Algebra by Bittinger, Ellenbogen and Johnson. The course is designed in 10 modules with each module broken into several sections. The learning objectives are given for each section. The material in each module was based on the CCSS as given in about 2010-11. Although nearly all objectives are “calculational”, conceptual questions for each objective should be included.
