evaluation of changes is hard
You say the statistics are a lie, okay give me some reasons why those numbers would have improved after they cut 37 teacher positions. Parents getting more involved, what changed? You would think the district would have looked at all changes that have occurred to make sure it was actually the computers?
One can hope that they have carefully looked, but the world is full of newly implemented plans of all sorts (educational, social, governance, industrial, etc.) which were never properly tracked or analyzed. "We changed this 'cause it seemed like a good idea, but no we didn't think about how we would measure the results, and we took no care to limit or track the confounding effects of other changes in the system." is the sort of statement you seldom see on reports or proposals, but truthfully it should be in bold on almost every project of this type that I have encountered.
Tracking and measuring this sort of thing is quite hard, so it is not surprising that it is often skipped or done poorly. It also costs more to do that sort of thing well (in time and implementation dollars), so it is often the first thing to scale back when resources are limited.
Possible confounding effects: perhaps the student cohort recently is different than the group ahead of them - I wonder what the statistics on year-to-year variation in the schools might be - maybe these results are within the expected "noise" of the system and many more years of data are needed to see if it is significant. The positive impact of almost anything "new" is well known in education research - will any effects persist beyond the 2-3 year window when the "new" system becomes the "standard/old" system both from the point of view of the students and the teachers. Are the benefits arising due to individual laptops or perhaps due to increased student tracking and focus on student outcomes? Perhaps the laptops are not necessary and just better tracking would have the same impact? Are the student outcomes actually what is desired? How well do the students perform on other tasks like independent work or critical analysis - there is much debate on the value of standardized testing - is that the best way to gauge results?
As an example, back in the 1990s I saw some work done at UIUC in computer led instruction for intro physics courses. They managed to produce data for a few years over a few thousand students showing that the students from sections of the physics course using this computer-aided instruction performed on average way better than those sections not using the computer delivered material. Then they had a few semesters where the effect largely disappeared. It was a mystery until it was noticed that the Math Department had changed their schedules for the "Advanced Intro Calc" course to conflict with the sections of the physics course using the CAI system. It turns out that much of the gains in the physics course was due to the people choosing to be in the CAI sections. Even when assigned randomly, external effects impacted which students got assigned to which section of the course enough to have significant impact on the resulting grade differences between students.
In any case, I am pleased that they seem to have positive results from their changes to their system, and hope that they do manage to maintain such improvements for the long term, and that they can figure out what parts of their changes were positive and if any changes have drawbacks. Anything that focuses kids, teachers, administrators, and the public on the challenges facing our educational system and on ways that it can be improved both individually and systemically would seem to be a good thing.
