11 Experiments That Failed
"This is a most joyful and clever whimsy, the kind that lightens the heart and puts a shine on the day," raved Kirkus Reviews in a starred review. Is it possible to eat snowballs doused in ketchup—and nothing else—all winter? Can a washing machine wash dishes? By reading the step-by-step instructions, kids can discover the answers to such all-important questions along with the book's curious narrator. Here are 12 "hypotheses," as well as lists of "what you need," "what to do," and "what happened" that are sure to make young readers laugh out loud as they learn how to conduct science experiments (really!). Jenny Offill and Nancy Carpenter—the ingenious pair that brought you 17 Things I'm Not Allowed to Do Anymore—have outdone themselves in this brilliant and outrageously funny book.
Failing in the Field

A revealing look at the common causes of failures in randomized control experiments during field reseach—and how to avoid them All across the social sciences, from development economics to political science, researchers are going into the field to collect data and learn about the world. Successful randomized controlled trials have brought about enormous gains, but less is learned when projects fail. In Failing in the Field, Dean Karlan and Jacob Appel examine the taboo subject of failure in field research so that researchers might avoid the same pitfalls in future work. Drawing on the experiences of top social scientists working in developing countries, this book describes five common categories of failures, reviews six case studies in detail, and concludes with reflections on best (and worst) practices for designing and running field projects, with an emphasis on randomized controlled trials. Failing in the Field is an invaluable “how-not-to” guide to conducting fieldwork and running randomized controlled trials in development settings.
