These in particular, expose the bias at Chalkbeat:
Errol Louis writes that the teachers union's call for parents to withdraw their children from taking the tests threatens to undermine the movement, which he argues is wrongheaded anyway because "high-stakes testing is, for better or worse, the norm in our complex modern society."
The Buffalo News weighs into the debate, also tying the opt-out movement to one that is being "driven by" the state teachers union.
Really? I know the people at Chalkbeat know full well the union, in particular the UFT, has played little role in what is a grassroots parent movement (as opposed to the astroturfs so often promoted by Chalkbeat). Yet this headline without comment allows the lie to go out -- a distortion of the real world. Chalkbeat reporters contact Change the Stakes asking for opt out information. (They won't get that from the UFT, which has done nothing to assist the opt out movement - and in fact, has obstructed it - see the turn down of the MORE testing reso at the March DA.)
In fact, CTS has so much info unbiased reporting would lead to offering the alternative view.
They can't use the excuse that they are just listing articles in the news without any comment -- in the old days of Gotham they at least used to offer the counter arguments from the blogs in their evening report.
I would tell you to go comment but really, why bother?
