Education Department Layoffs Would Affect Dozens of Programs. See Which Ones Entire teams that work on key funding streams may not return to work even when the shutdown ends.

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...

Fraction comparison strategy: Same parts away from the whole

I also cannot help but think of Oklahoma as Indian country & this as another attempt at pushing white colonial narratives on native kids.

Trump cut its grant, but Wake County will still offer therapy in every school With parental consent, Wake County students can get therapy from their school to deal with issues such as anxiety and depression.

Mathematical modelling for biologists - Modelling concepts in biological research Mathematical modelling for biologists - Modelling concepts in biological research

My PhD student @leonielorenz.bsky.social (with Eva Geissen) has made this nice (free) online course to introduce mathematical modelling for biology:
www.ebi.ac.uk/training/onl...

Including both molecular and epidemiological examples

Ph.D. students Devan Mackenzie and Hajra Fayyaz plus @dyong.bsky.social and I have a new chapter out. We worked with a group of teachers to work out what culturally sustaining pedagogies might look like in math and computer science classrooms www.igi-global.com/book/cultura...

"I am the Oracle. I can answer any question you ask." "What is 0^0?" "Any question but that."

The value of 0⁰ seems like a plot hole.

Mathematical models turn patient data into life-saving insight Find out how mathematical research is unlocking new value from complex and underused intensive care unit (ICU) data.

Great blog from two of our PhD students on our CHIMERA hub about using mathematical models and vital signs data from intensive care to support clinicians

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

I created a generic GD version of our team's response plan, including a draft appeal*, based on compiled guidance.

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".

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:

This is your periodic reminder: NSF's Directorate for STEM Education (EDU) *still* remains paused in new awards.

Here's an updated graph. But also see below thread about why the nation needs these #STEMed investments, including for sustaining the *future* of scientific research.

Thank you! I didn't know this existed!

‘I Want to Stand Up for Higher Ed’: Protesters Rally Against Education Dept. Cuts As demonstrators gathered in Washington, D.C., researchers met across town to discuss the toll that drastic reductions at the agency would have on their work.

Education researchers seriously doubt that the Education Department will be able to maintain the federal data sets after half the agency’s staff was fired. chroni.cl/4bTbeQk

...This piece is really important because we are not allowed to communicate this to grantees, but it could potentially help a lot of people about to submit stuff if they just knew to avoid certain words on their biosketch and other support."

From an NIH source re. grant terminations

"These searches are pulling in things based on 'other support' sections and biosketches, so science may be held up just because someone mentions that they serve on a DEIA committee, or has a completely different grant that uses a 'problematic' word.
