## Did any Chicago teachers participate in #mtt2k?

In the Khan Academy video critiques did any Chicago teacher participate?  Or even leave a comment?

http://chicago.cbslocal.com/2012/06/12/how-much-do-chicago-public-school-teachers-make/

A Chicago Public Schools spokesperson said average pay for teachers, without benefits, is \$76,000.

As far as we know, the entire Chicago public school system was completely unaware of the Khan Academy video controversy.   If they are that indifferent, it is hard to see they are worth that money in a city that is sliding into collapse from 3rd world demographics taking over.

As indicated in the explanation of the determination of the national average wage index (AWI), the latest annual change in the “raw” average wages is applied to the last AWI to obtain the next one. Such raw average wages are the average amounts of net compensation (as distinct from total employee compensation) listed in the table below.

An average is just one measure of central tendency for any set of data. Another measure is a median. For our wage data, the median wage (or net compensation) is the wage “in the middle.” That is, half of the workers earned below this level. The table below shows that the median wage is substantially less than the average wage. The reason for the difference is that the distribution of workers by wage level is highly skewed.

Note: Median net compensation is estimated.

Average and median net compensation are shown in the graph below. Also shown is the ratio of median to average amounts.

An excellent lesson or two on average and median is in this data.

High stakes testing is showing that 3rd world populations in America are not able to do first world type performance.  Thus we can’t pay teachers 76,000 dollars a year in the Chicago school system which is heavily 3rd world now.  It provides no benefit to do so.

The median wages of the students who come out need to support the pay of the teachers.  This is not happening in 3rd world America.  So we can’t pay teachers 76,000 a year to teach a 3rd world school system in Chicago.

Moreover, the teachers are not even paying attention to Khan Academy video critiques or Gary Rubinstein’s master class in how to teach.  This is because they are just trying to survive in their classrooms?  So teaching math is an abstract concept foreign to the Chicago school system?
