Summary

Intended for a first-year-level developmental mathematics course in intermediate algebra,Exploring Intermediate Algebra: A Graphing Approachis designed to assist students in making connections between mathematics and its applications. Its goal is to develop a student's mathematical skills through appropriate use of applications and to use technology to establish links between abstract mathematical concepts and visual or concrete representations. The provenAufmann Interactive Method(AIM) ensures that students try concepts and manipulate real-life data as they progress through the material. Every objective contains one or more sets of matched-pair examples encouraging students to interact with the text. The first example in each set is completely worked out; the second example, called 'You Try It,' prompts students to practice concepts at the time they are presented in the text.Complete worked-out solutionsto these examples in an appendix at the end of the book help students by providing immediate feedback, concept reinforcement, and identification of mistakes to prevent frustration. Technology is integrated throughout the text to assist students in making connections between abstract mathematical concepts and a concrete representation provided by technology. Eduspace, powered by Blackboard, for the Aufmann/Lockwood/BoswellExploring Intermediate Algebracourse features algorithmic exercises and test bank content in question pools.
