When William Schmidt, an expert on math education at Michigan State University, moved his family from East Lansing to Charlottesville, Virginia for a year’s research leave, his work took a personal turn. He noticed that the public school his daughters would be attending outside Charlottesville was academically behind the one they had attended in Michigan. Back home, his 2nd grade daughter would be learning multiplication tables up through the number 5, yet in Charlottesville, multiplication was not even part of his local school’s second grade curriculum.
His daughter’s experience, he explains in a new book excerpted below, is not unique. ” The [American] system of schooling represents a game of chance that few are even aware is being played,” he writes in “Inequality for All: The Challenge of Unequal Opportunity in American Schools,” co- written with Curtis C. McKnight. The inequalities pose a risk to every child, they write, regardless of socioeconomic background or race. They stem from differences in state education standards, in school funding, in curricula that districts choose to adopt and in the content that individual classroom teachers choose to teach. In this excerpt, Schmidt and McKnight focus on variations in how math teachers are trained and how that, in turn, affects student achievement.
The following is excerpted from Inequality for All: The Challenge of Unequal Opportunity in American Schools, by William H. Schmidt and Curtis C. McKnight. (Teachers College Press, 2012).
