QUANTITATIVE LITERACY, 3E FEATURES
In the News
Throughout the text, explanations, examples, and exercises are often motivated by everyday events reported in the popular media. Each chapter and each section opens with real articles gleaned from newspapers, magazines, and Internet sites. They are presented under the feature titled In the News. These lead naturally to discussions of mathematics as part of everyday life. For example, In the News 2.1 launches a discussion of the different ways to present data and the advantages and dis advantages of each.
Examples in the text are selected as much as possible for their relevance to student experience. For instance, Example 4.26 shows students how to calculate the finance charge on clothes purchased on credit.The solution for this example includes a clear and complete explanation that students can follow and reference when solving similar types of problems.
Try It Yourself
Many worked examples are followed by a very similar problem that gives students the opportunity to test their understanding. This feature serves to actively engage students in the learning process. The answers to the Try It Yourself problems are provided at the end of the section so that students can check their solutions.
What Do You Think?
The new “What Do You Think?” feature encourages students to apply their critical thinking skills as well as their verbal and written skills. “What Do You Think?” questions can invite many correct responses.
Exercise sets are designed to help students appreciate the relevance of section topics to everyday life, and they often include direct references to popular media. They demonstrate a wide variety of applications and challenge students to think more deeply.
Many students are visual learners, and we have used graphs, photos, cartoons, and sketches liberally throughout the text. Many illustrations are paired so that students can easily compare and contrast similar concepts.
While most mathematics books state definitions of terms formally, we have chosen to define terms in a concise and informal way and to label each as a Key Concept. We do so to avoid intimidating students and to focus on the concepts rather than dry terminology.
Calculation Tips and Technology Support
Tips are provided to help students avoid common errors in doing calculations. Tips include advice for preparing to make a calculation and helpful hints for carrying out a complex calculation. Where appropriate, a screen shot of a calculator is used to reinforce correct data input when solving problems.
Students may occasionally feel overwhelmed by new concepts, so throughout each chapter we provide brief boxed Summaries of core concepts. This is an opportunity for students to pause, collect their thoughts, and reinforce what they have learned. Summaries also serve as reference points when students are solving exercises.
Rule of Thumb Statements
One facet of quantitative literacy is the ability to make estimates. The
Rule of Thumb
feature provides hints on making such "ball-park" estimates, offering a simple and effective check to catch possible errors in exact calculations.
Each chapter ends with a
, which consists of a representative sample of exercises intended to give students a review of the major points in the chapter and a chance to test themselves on the concepts they have learned. These exercises are accompanied by answers and references to worked examples in the text.
