Math Wars Continue
"Tough New Math Books" Aren't Helping Kid s

An ancient Chinese curse says, “May you live in interesting times.” We teachers certainly live in “interesting times,” as the math curriculum wars continue, and schools, parents, and students are caught in the crossfire.

As a classroom teacher of many years experience, I, for one, am not impressed with the new state standards and what some have touted as the “tough new math books.”

The adoption of math standards and textbooks is increasingly based on politics rather than on the experience of teachers and the findings of researchers. As each set of standards is published, textbook companies scramble to write programs which meet the new criteria, often producing poorly-written books which cover far too many concepts at each grade level. Like the Missouri River, these programs are a mile wide and an inch deep.

Moreover, “raising the standards” often merely means teaching in 1st grade what was once taught in 2nd grade, and so on – regardless of children’s readiness.

To make matters worse – in the rush to “cover everything” – there is a tendency to dispense with the hands-on materials and visual aids which learners need.

Thus the use of the new math books results in the worst of all possible worlds for many children – math instruction that is very difficult, yet fails to support real understanding .

As with the “reading wars” there is a middle ground. Kids do need basics. There are facts which they must memorize and procedures that should come automatically with practice. At the same time, kids should understand what they are doing, and be able to apply what they know in different situations.

It’s time to call a truce in the math wars. In Professor Arnold Schoenfeld’s words “. . .we need more than change for the sake of change, more than political rallying cries and radically new goals and tests every few years. What we need is evolutionary growth in the direction of well established goals. . .”  Otherwise, the pendulum will continue to swing – from “fuzzy math” to “tough new math books,” whose message to students is, “If you don’t understand math – that’s tough!”
