didn't see anything earlier on this thread but that implies that scores
would go down. You wouldn't be comparing schools with and schools
without, but the same school over time. Mickey, is there some evidence
for your statement?


Gerry:   would you not agree that even such a comparison as you
desscribe might be insufficeint, unless you can demonstrate that all
other factors were control except the change to a block schedule?  And
is not one of the basic comlaints of many on this baord thatcomparison
of this years students to next years sutdents is not a compeltely valid
comparison, that is, we may be compring diffrent student characteristics
rather than the difference in instructional delivery, even if every
other factor were held constant?
