The new edition uses "HeatMap" technology to advise the revision.Systematic and precise feedback from thousands of students was anonymously collected using LearnSmart. Because virtually every paragraph in the previous edition is tied to several questions students answer in LearnSmart, the author was able to see where students struggled most...the "hot spots"...and in turn refine and update these areas to be more clear, more concise, and more impactful.
