Guest: New math textbooks are the right choice for Seattle schools

Earlier this year, the Seattle School Board changed the kind of math textbooks used in our elementary schools, selecting texts intended to be used with explicit instruction. Under explicit instruction, teachers are expected to actually teach rather than turn students loose to discover mathematics principles on their own. The board picked the Math in Focus series, a version of Singapore Math.

Seattle Public Schools began using reform math textbooks in the 1990s. In that approach, students are supposed to learn by discovering mathematical truth in the process of solving problems. They typically work in groups, noting their thoughts in journals and portfolios, and using calculators constantly as they complete discovery-type projects. Advocates have touted reform math as a way to get kids excited about math and create a culture of learning.

Unfortunately, this approach was based on an unrealistic vision rather than on fact. It has been a failure both in Seattle and in the U.S. as a whole; our math students have fared poorly in comparison with those of other developed countries. On the most recent international math test, the 2012 Programme for International Student Assessment (PISA), the U.S. finished 36th of the 65 countries participating, behind virtually all other developed countries. Earlier tests showed similar results.

During the last seven years, my students at Ballard High School consistently performed better than their peers at other public Seattle high schools on Advanced Placement Calculus exams. Since 2011, when state end-of-course tests were established, I have taught only one class that has a state test and is required for graduation — Algebra 1, our school’s lowest-level math class, in the 2011-12 school year. My students earned the highest passage rate in the district on that test.
