A heat dome has settled over much of American education. Is Gov. Scott Walker just going to add to the stifling atmosphere? Or is Walker right that there are cool breezes in his ideas for how to increase school quality overall?
First, the national perspective: You would think by now, the heat would have been drained from some of the debate about what works in education, especially when it comes to serving urban kids. People have been working on this for decades. Haven’t we figured out answers yet?
In most ways, no. Even a lot of things that seem like answers haven’t been brought successfully to wide use. Things that look good on paper (or in a political speech) have often accomplished little in reality. The profoundly troubling march to perpetuating educational failure, for the most part, continues.
As disappointment grows, the debates between “education reformers” and those who think the “reformers” are going in the wrong directions often have been contentious. If you follow the tweets and postings and such, you’ll find occasional light but a lot of heated rhetoric. Add in this year’s wars over the pay, benefits and unions of public employees, combined with the hyperpartisan nature of the times, and you have an atmosphere that should carry health warnings.
