NAEP Math Results: Ohio and Wisconsin Comparison
The 2007 NAEP results have just been released. There are many interesting results one can learn by looking at this data. In addition to the very serious racial gap in Wisconsin which has been commented on by The
Educational Trust [

Grade 8 Math NAEP Analysis |
80K PDF] and the
Wisconsin Department of Public Instruction [
172K PDF], there are strong indications of other problems in mathematics education in Wisconsin. Consider the following data comparing results for whites and blacks in Ohio and Wisconsin from the first year NAEP results were given by states and the 2007 results. As background, 12 points on NAEP is generally thought to be about the change from one year to the next on a given test. This is not a good estimate when looking over 15 to 17 years, since part of the rise in the test score likely came from changes made in textbooks and in what teachers teach because of the change in the NAEP Framework in the early 1990s.
For example, in
Trends in Mathematics and Science Study, TIMSS, fourth grade math was tested in 1995 and 2003, and the results were flat while the NAEP results went up enough to allow statisticians to conclude the increase was statistically significant.
I assume that some of the rise in NAEP over this period is because students are learning more about the topics covered in NAEP, but that this is not the only
reason for the rise in NAEP scores.
The data below is comparison data between the results in two states at two different years, so the point estimate for a year of schooling seems to be a reasonable guideline. If so, Wisconsin has lost about a year to Ohio. Something needs to be done about this.
