New state test results show that Prince William County’s third-graders are struggling to score at the highest level since the implementation of a controversial math program that was intended to boost performance.
The scores, which are the first state Standards of Learning (SOL) results to gauge the new program’s effectiveness, reveal that fewer than half of Prince William’s third-graders scored in the advanced category this year, the first that the Pearson math program “Investigations in Number, Data, and Space” was taught in that grade. Last year, third-graders who had not begun “Investigations” posted the same results.
The flat scores are a sizable decline since 2006, when 56 percent of third-graders reached the advanced level in math.
” ‘Investigations’ didn’t cure the problem,” said Vern Williams, a Fairfax County teacher and former member of the National Mathematics Advisory Panel who was invited by the Prince William School Board to speak at its work session later this month.

It will be interesting to see what, if any effect the soon to be released Madison Math Task Force report has on the local curriculum.
