The first is that teachers of statistics have much to learn from those whose primary expertise is the study of learning. We statisticians tend to insist that we teach first of all from the base of our knowledge of statistics, and this is true. Teachers at all levels must understandtheirsubject matter,andatadepthatleastsomewhat greaterthanthatof the content they actually teach. But teachers must also understand how students learn, be aware ofspecific difficulties, and consider meansto guide studentstoward understanding. Unaided, we gain skill intuitively, by observing our own teachers and by experience. Teachers below the university level receive specific instruction in teaching—this is, after all, their profession—and this book will improve that instruction where statistics is concerned. Teachers at the university level consider themselves first of all mathematicians or psychologists or statisticians and are sometimes slow to welcome pedagogical wisdom from other sources. This is folly, though a folly typical of professionals everywhere. I have learned a great deal from some of the editors and authors of this book in the past, and yet more from reading thisvolume. Second,thisbookistimelybecausedata-orientedstatisticshasatlastmovedinto the mainstream of mathematics instruction. In the United States, working with data is now an accepted strand in school mathematics curricula, a popular upper- secondary Advanced Placement syllabus adds a full treatment of inference, and enrollment inuniversity statisticscoursescontinuesto increase. (Indeed, statisticsis almost the only subject taught by university mathematics departments that is growing.) Similar trends, particularly in school mathematics, are evident in other nations.Thetitleofthisvolume,withitsemphasison“statisticalliteracy,reasoning, andthinking”reflectstheacceptanceofstatisticsasamainstreamsubjectratherthan ix
