Comment: Logic? (Score 1) 519

Found the Tentative Decision at

On page 8 it says

"Dr. Berliner, an expert called by State Defendants, testified that 1-3% of teachers in California are grossly ineffective."

There is a huge difference between 1% and 3%. (That's like saying "I'll be there in 5 hours +- 2.5 hours"). On the other hand, how many "grossly ineffective" workers / managers are there in other professions?

Now, why have these teachers been hired? Is eliminating tenure really going to change this figure? Are competent teachers going to get fired because they don't have tenure? Why is the waiting period only 2 years? Similar considerations are discussed at

With complicated systems like this, it makes no sense to look at one single element, and blame only it. So the decision will have large gaps in the logic.

Always find it a bit odd when people complain about documentation, or place emphasis on it. My first prioroty is, "it works".

On the other hand, it is hardly clear in most cases, who the audience of the comments are. Do they know much, do they know little? If they know little, there needs to be a lot of documentation. Who is to say?

So when I hear about people, who mention bad documentation, or who complain about some documentation, it strikes me a bit odd.
