I'm so sad to hear this. He was one of the greatest professors I ever had. A marvelous mathematician but also a wonderful human. May his memory be a blessing.

New: More than $50 billion (yes, with a b) for education is in jeopardy if the Education Department eventually proceeds with the layoffs it implemented last Friday. A federal judge put them on hold as of Wednesday. Here's a list of the affected funding streams: www.edweek.org/policy-polit...

Our argument: ◾ Most research summarizing high quality PD proposes lists of features of quality PD ◾ BUT, while there is a general consensus, there are points of contention. What is more, there are examples of PD that meet the criteria set out on the lists but don't support meaningful learning

Who bears the brunt of these cuts? Well, here's a word cloud of the most frequent terms from the titles and abstracts of terminated grants, with word size proportional to frequency:
A word cloud, with words of different sizes, and different colors, with purple for the largest, red medium, and green small. "Black" stands out prominently in purple. In red, we see "climate", "student", "network", "justice", "identity", "teacher", and "undergraduate".
