TIMSS 2011

http://timss.org/

Results from the fifth Trends in International Mathematics and Science Study (TIMSS) came out earlier this week.

Based on last year's assessment of 63 countries and 14 benchmarking participants, TIMSS 2011 International Results in Mathematics measures trends in math achievement at the fourth and eighth grades.

The report runs eight chapters and eight appendices, with an executive summary and references. Freely download each section one at a time — or the combined 66MB document in one fell swoop from here:

Video summaries address trends in student achievement, the importance of home environment and preprimary education ("An Early Start"), and factors for academic success:

PoW taking place: math problem-solving moment of the week

"Others, like Lee, Lu, and Eric, all went one step further. While Lee does a good job explaining his thinking, Lu and Eric also made nice charts. Ann used slightly different thinking. She tried numbers that fit those two rules, as you can see in her solution. Turning to Lauren, she did something pretty neat that only a few of you did. She also determined that pencils must cost four cents more than erasers, but then used that information very creatively...."
- Riz, commenting on the FunPoW's latest solution

Graphing Stories

http://graphingstories.com/

Dan Meyer and the BuzzMath Team recently posted over twenty short videos designed to orient students to abstract and graphical representations.

Check out the clips of stories — each 102 seconds in length — to graph using the freely downloadable accompanying student template. Select from among story subjects, which range from balls and carnivals to ponies and water; or types of graphs:

  • constant
  • decreasing
  • increasing
  • linear
  • parabolic
  • periodic
  • piecewise
  • step graphs


Now taking place: math education conversation of the day

"I thought about Robert's son when I read this article. Has anyone in the Math Teach community seen this app?"

Easy Stats from the Census Bureau

http://www.census.gov/easystats/

The U.S. Census Bureau has a new interactive tool for selected demographic and economic statistics.

Drawing on information from the yearly American Community Survey, Easy Stats reports on education, housing, jobs, and more by geography — down to the local level of incorporated places, like cities and towns.

Detailed race, age, and gender breakdowns include

  • School Enrollment by Detailed Level of School for the Population 3 Years and Over
  • Family Income in the Past 12 Months
  • Poverty Status in the Past 12 Months of Families
  • Means of Transportation to Work
  • Geographical Mobility in the Past Year for Current Residence in the United States

From the results of any search, click in the lower right corner on the green "MS Excel" icon to download the data in spreadsheet format.
