  •  and so you universalize from one study (2+ / 0-)

    that agrees with a position you already hold?

    Have you read possible responses to that study that maybe point out how it has a flawed methodology, or systematically excludes data that would counter its conclusions?

    Reducing class size from 30 to 28 really does not make a difference  Reducing it from 40 to 28 usually does.

    If attempting teach reading or writing, having more than 30 students in one class is very ineffective.

    Oh, and if class size is so unimportant, why do so many private schools advertise directly on their class size?  Why is one key factor in the US News rating of colleges/universities the percentage of class with less than 20 students.

    Merely decreasing class size without providing appropriately trained teachers for the additional classes thereby created is of course not effective.

    But if one is able to provide quality teachers, most studies on reduced class size demonstrate increased learning and on task behavior.  That has been true for many years and through many studies.

    •  Tennessee STARS (0+ / 0-)

      Over 7,000 students in 79 schools were randomly assigned into one of three interventions: small class (13 to 17 students per teacher), regular class (22 to 25 students per teacher), and regular-with-aide class (22 to 25 students with a full-time teacher's aide).  Classroom teachers were also randomly assigned to the classes they would teach. The interventions were initiated as the students entered school in kindergarten and continued through third grade.

      A significantly larger percent of small-class students (52.9%) versus students who had attended regular (49.1%) and regular/aide (48.0%) classes passed the TCE Language requirement at grade 8.

      The same was true for the mathematics requirement, where 36.4% of the small-class students passed versus 32.3% of the regular class and 30.3% of the regular/aide class students.

      For about 50% more money in four years of regular education one can get 20% more pass grades in math and 10% more pass grades in language skills.

      The somewhat better language skills have some economic value, but I suspect better math skills probably have very little economic or even practical value to society in the age of debit/credit cards and tax software programs.

      The average young American might be better off given the increased cost per student in a trust fund.

      A man in Chattanooga once asked me for money. I thought he was crazy. After a minute I realized he simply lacked teeth. I think he said false teeth would cost $300.

      •  I am quite well aware of STARS (0+ / 0-)

        having referred to it in one of my first published pieces about a decade ago

        there are limitations to the study, and to generally apply the results without regard to the limitations is simply wrong.
