If you ever said ‘I’m no good at numbers, ‘ this book can change your life , said Gloria Steinem of the first edition of Overcoming Math Anxiety in 1978. And lives were changed. Sheila Tobias said it first: mathematics avoidance is not a failure of intellect, but a failure of nerve. To thousands who once thought they were too dumb in math to do anything about it, Tobias’s political and psychological analysis brought hope. Her pioneering efforts to take the sting out of math made math anxiety a household word. What makes Overcoming Math Anxiety different from books like Innumeracy or Math Made Easy is the author’s role and purpose. Neither a mathematician nor a math teacher, Tobias positions herself on the side of her readers. She knows what they are thinking, because she thinks that way herself. I was always trying to turn math expressions into words .. . she says. The first time I saw negative numbers, I felt confused .. . While her analysis of the causes of their math anxiety (the moment when their third-grade teacher made them stay at the blackboard hunting vainly for their mistake) is an important focus, most of all Tobias wants her readers to face up to the cost of math avoidance in their lives. Why is a smart girl like you counting on your fingers? If you could do math, what else could you do? The new edition retains the author’s pungent analysis of what makes math hard for otherwise successful people and how women, more than men, become victims of a gendered view of math. The chapters on Mathematics and Sex and Right- and Wrongheadedness have been substantially updated to incorporate new research which demonstrates how little we really know about sex differences in brain organization and function. The hands-on experience in Word-Problem Solving , Everyday Math , and Sunday Math have been enlarged to include problems, puzzles, and strategies tried out in hundreds of math anxiety workshops Tobias and her colleagues have sponsored and observed in the past fifteen years. The programs described in detail in the last chapter are all new and include programs for women only, and those with substantial appeal for adults of both sexes returning to school for the training they need to get ahead. What remains unchanged is the author’s politics. Indeed, she sees math anxiety as a political issue. So long as people believe themselves to be disabled in mathematics and do not rise up and confront the social and pedagogical origins of their disabilities, they will be denied math mental health . Tobias defines math mental health not as some bottom line of mathematical competence but as the willingness to learn the math you need when you need it . From this perspective, in an ever more technical society, overcoming math anxiety can make the difference between high and low self-esteem, failure and success.
