Math murdered

Over on Weapons of Math Destruction, Oak Norton and Bob Bonham have another fun cartoon. It shows a police officers examining an outline on (presumably) a street; the caption begins, “Common sense was seen fleeing the crime scene….”

Some factors affecting effectiveness

According to an analysis by Gregory J. Palardy and Russell W. Rumberger, differences in teacher effectiveness have larger effects on young children’s outcomes in reading and math than do differences in teachers’ backgrounds factors such as level of education and types of certifications held. The teacher quality effects were also substantially greater than the effects for children’s families’ SES in their study and than the effects for class-size reduction (25 25 versus 15 students per classroom) reported in another study.

Professors Palardy and Rumberger arrived at this conclusion by analyzing data from a large data set that is representative of students in the US. They used a sophisticated analytic approach that permitted them to assess the effects of inputs, processes, and outputs at the school, classroom, and individual student levels.

This study uses Early Childhood Longitudinal Study data to investigate the importance of three general aspects of teacher effects—teacher background qualifications, attitudes, and instructional practices—to reading and math achievement gains in first grade. The results indicate that compared with instructional practices, background qualifications have less robust associations with achievement gains. These findings suggest that the No Child Left Behind Act’s “highly qualified teacher” provision, which screens teachers on the basis of their background qualifications, is insufficient for ensuring that classrooms are led by teachers who are effective in raising student achievement. To meet that objective, educational policy needs to be directed toward improving aspects of teaching, such as instructional practices and teacher attitudes.

Bad math brain

Click for larger version from Weapons of Math Destruction

Those clever folks over at Weapons of Math Destruction have stuck yet again with another witty take-down of mal-education in the mathematics area.

As much as I like this one, I think the image of the face for the child “on fuzzy math” should be different. I see fuzzy math and its cousins as resulting more in happy witlessness. That’s the idea: Make it fun and engaging; students’ll just figure it out magically…re-discovering everything from counting through Archimedian insights and onto the calculus. Shouldn’t those kids be smiling?

For those outside the US who are not familiar with the brain-vs-brain-on theme incorporated into this cartoon, here’s a hint: There was an advertisement that first appeared in the 1980s showing a man holding a chicken egg and saying “This is your brain,” then cracking the egg into a frying pan and saying, “This is your brain on drugs.” Here’s a link to a Wikipedia entry about the brain-on-drugs advertisement.

Oh Well…off to a thumbnail catalog from Weapons of Math Destruction for the big version of this cartoon.
