A fast-food chain once tried to compete with McDonald’s quarter-pounder by introducing a third-pound hamburger—only for it to flop when consumers thought a third pound was less than a quarter pound because three is less than four. Separately, a rash of suicides by teenagers who played Dungeons and Dragons caused a panic in parents and the media. They thought D&D was causing teenage suicides—when in fact teenage D&D players died by suicide at a much lower rate than the national average. Errors of this type can be found from antiquity to the present, from the Peloponnesian War to the COVID-19 pandemic. How and why do we keep falling into these traps? James C. Zimring argues that many of the mistakes that the human mind consistently makes boil down to misperceiving fractions. We see slews of statistics that are essentially fractions, such as percentages, probabilities, frequencies, and rates, and we tend to misinterpret them. Sometimes bad actors manipulate us by cherry-picking data or distorting how information is presented; other times, sloppy communicators inadvertently mislead us. In many cases, we fool ourselves and have only our own minds to blame. Zimring also explores the counterintuitive reason that these flaws might benefit us, demonstrating that individual error can be highly advantageous to problem solving by groups. Blending key scientific research in cognitive psychology with accessible real-life examples, Partial Truths helps readers spot the fallacies lurking in everyday information, from politics to the criminal justice system, from religion to science, from business strategies to New Age culture.

This book may be used for research, graduate and undergraduate teacher education, and teacher development. It presents an integrated set of studies of a heterogeneously grouped class of twenty-one nine-year olds, engaged in exploring fraction ideas prior to classroom instruction under conditions that supported investigation, collaboration and argumentation. It demonstrates with text and video narrative how young children can reason about mathematics in surprisingly sophisticated ways when provided the opportunity to do so in the proper classroom environment. In this volume, fourth grade students’ reasoning about fraction concepts is described through careful analysis and accompanying video excerpts showcasing the variety and originality of their thinking. These children will serve as an inspiration for educators to encourage the development of reasoning and argumentation in their students as part of a mathematics curriculum designed to produce critical thinkers.

Microsoft Excel continues to grow in power, sophistication, and capability, but one thing that has changed very little since the early '90s is its user interface. The once-simple toolbar has been packed with so many features over the years that few users know where to find them all. Microsoft has addressed this problem in Excel 2007 by radically redesigning the user interface with a tabbed toolbar that makes every feature easy to locate and use. Unfortunately, Microsoft's documentation is as scant as ever, so even if users can find advanced features, they probably won't know what to do with them. Excel 2007: The Missing Manual covers the entire gamut of how to build spreadsheets, add and format information, print reports, create charts and graphics, and use basic formulas and functions. Like its siblings in the Missing Manual series, this book crackles with a fine sense of humor and refreshing objectivity about its subject, guiding readers through the new Excel with clear explanations, step-by-step instructions, lots of illustrations, and friendly, time-saving advice. It's a perfect primer for small businesses with no techie to turn to, as well as those who want to organize household and office information.
