1/ Happy St. Patrick’s Day! 🍀🌈

Did you know clovers can be plotted? 🍀📈 Let’s take a look at these lucky leaves from a mathematical perspective!

A three-leaf clover is called a trifolium— or in French, paquerette de mélibée, with paquerette meaning "wild daisy” 🌼

‘Pupils are in fear every day’: parents raise concerns about new schools run by top UK academy Emergency meeting called over strictness of discipline at Essex schools run by Mossbourne Federation

If this is true it is absolutely
appalling.

Yes, behaviour can be a real issue in schools and it’s easy to criticise
from outside.

But no decent person rules by fear and humiliation

Is it school reluctance or refusal? How to tell the difference and help your child If your child is spending lots of time in sick bay or has extreme difficulty getting ready for school, they could be signs of school refusal.

There has been a lot of discussion about school refusal and non attendance here in the UK over the last year or so, due to significant rates of pupil absence. Here's a reminder that attendance issues aren't unique to the UK.

A bird's-eye view of a former Auschwitz II-Birkenau camp showing a wide dirt pathway flanked by parallel rows of barbed-wire fences. Groups of visitors walk along the path, surrounded by the remnants of brick structures and barracks, now reduced to foundations. Green grass contrasts with the somber history of the site, as the path leads toward a guard tower in the distance.

Auschwitz was at the end of a long process. It did not start from gas chambers.

This hatred was gradually developed by humans. From ideas, words, stereotypes & prejudice through legal exclusion, dehumanization & escalating violence... to systematic and industrial murder.

Auschwitz took time.

WEEKEND READING: Why Scotland's student funding system is "unfair, unsustainable, unaffordable" and needs to be replaced with a graduate contribution model - HEPI Thanks to the CDBU and to HEPI for the invitation to attend and take part in today’s discussion.  My speech today has been titled ‘A graduate contribution model’. Of course, for UK graduates not from ...


An interesting piece. Whilst my instinct is always to like the principle of free HE (not least from wanting others to have what I enjoyed back in the 80s), the consequences of the numbers cap described here are very worrying

L.A. Fire Devastates Historic Black Community in Altadena (Gift Article) For Black residents, Altadena represented something more than suburban living. It was a foothold in generational prosperity.

The scale and depth of tragedy in Los Angeles is so heartbreaking. 💔 The MSM has largely focused on the wealthy enclave. I am so glad to see coverage like this about the Altadena community #blacksky
