City Club: Huberman Wants To Share Performance Data

applebeesfsaopaulo.jpgEvery year around this time the head of the Chicago Public Schools gives a speech, and this year is no different.  I don't have a copy of his remarks yet but WBEZ has the tape (here).  Big news -- if proposing something is big news -- is that Huberman wants to evaluate teachers based on performance data.

  • Mr. Huberman gave a very impressive performance. I have listened to the same presentation made at the City Club by Mr. Duncan and Mr. Huberman's was techincally much better. Now that does not mean I agree with what he said. But he spoke to the interests of the club and he pushed his overall agenda in what appeared to be a very rational and well thought out manner. He also made the Mayor look very good as part of his presentation. I would give him very high marks overall.

    But I also think Mr. Huberman and his staff should re-think their comparison of Noble Street charter's ACT gains to those of Payton Prep which he made in his presentation. He noted that the gains of Noble Street were far higher than those of Payton. This comparison in inteclectually absurd. The as a school's average ACT score rises into the 20s moving the average score higher becomes very hard or next to impossible unless a school like Payton reduces admissions to only those students who a psychologist would determine to be gifted based on combined IQ scores and academic testing. I thought his comment in relation to this issue was very poorly thought out.

  • I've considered this for years. I realized that even if all of the students in my school mastered college readiness skills and used those skills to earn a degree, Wal-Mart still would be the largest private employer in the country and largest corp in the world. The Waltons use much of their philandrophy funds for charter school movements. Perhaps there are no evil henchmen plotting a master plan for global domination, but it sure is working out that way.

  • Re: Rodestvan's comment on Noble's ACT scores vs. Payton's scores, from the NY Times. This article mentions the reliability of the statistical technique called value-added analysis, which Duncan is pushing through his Race to the Top program.

    "Another problem is known as the ceiling effect. Advanced students can score so highly one year that standardized state tests are not sensitive enough to measure their learning gains a year later.

    In Houston, a district that uses value-added methods to allocate teacher bonuses, Darilyn Krieger said she had seen the ceiling effect as a physics teacher at Carnegie Vanguard High School.
