says yet again that “Schools are safe”, because children are at low risk of serious disease.
With current v high disease prevalence (maybe 1 in 20 or 30 in #London ,#1in50 elsewhere) MORE children will catch #coronavirus & MORE children will become very ill. 1/8🧵

What does it take to sustain screwiness in the way the world works? Mostly, it's just good people, trying their best to get us to a better place... within constraints which pretty much preclude us actually getting anywhere! A case in point with

These authors come across as hugely committed to something we might all agree upon: improving young people's experiences of physical education through better school-based-interventions. Sounds great? Agreed, & pretty much everything about their study models best practice 🥳

Sadly, established "best practice" involves further embedding the medicalisation of PE as if it should be about the potential contribution of physical activity to everything from quality of life, self-perception & cognition to the likelyhood of becoming healthy & active adults 🤯

We're reminded of the Chief Medical Officer's "recommended guidelines of 60 min of moderate-to-vigorous physical activity (MVPA) per day for healthy growth and development" 👇 This is a focus on what we can easily measure (generic) rather than on what we might value (individual).

We get recognition that PE "is not merely an opportunity for children to engage in PA" but that's linked to its role in "the development of knowledge & skills to foster their PA engagement throughout life" - so further focus on health outcomes. A long way from @meaningfulPE 🙄

On teaching without grades.
A long-ish (20-tweet) 🧵. Here goes.

So, you know how you write lots of comments on an essay/exam, and the student looks at the grade and never reads the comments? That's because when grades enter the picture, the learning stops. /1

Instead of focusing on learning, there is a lot of negotiation: can we find one or two points on the midterm as the student is just on the verge of A-?

Everyone is just on the verge of the next grade.

And all the evals are not about the class but about the grading. Really? /2

Is the grade at all informative? If you are just below the A- or just above that, is that giving the student any information about how to improve their knowledge or skills? No. t is just a useless, demoralizing & stressful smoke screen /3

Students' abilities, challenges, and learning are multidimensional. Providing feedback on these many dimensions is much more useful for promoting growth and learning than are quantized unidimensional grades. /3.5

There is an alternative: do away with grades. Keep the feedback -- lots of it (this is not less work for us teachers) but never summarize it in a unidimensional uninformative number (unless you absolutely have to). /4

Hi teachers and parents 👋 I have complied a short list of useful online maths tools and virtual manipulatives to assist you with distance learning. I have included the curriculum area and suggested what class group they would be most suitable for. See below! #mathschat #edchatie

This website allows you to create a graph. Useful for 5th/6th class. Children can create pie charts, bar charts, etc. adding in their own data and designing and labelling the X and Y axis themselves. Charts are easily

Online protractor. Useful for 5th/6th class. The teacher can use screen sharing to how to use a protractor. Children who do not have a protractor at home can use this to measure angles.

Exploring area and perimeter. Useful for 4th - 6th class. Tasks can be set to create shapes of a specific area/perimeter. There is also a game that can be used for formative

Interactive geo-board. Useful for 1st - 6th class for exploring perimeter and area and the characteristics of shapes. Images can be saved easily to be shared with the teacher via email, screen share etc.

Unexpected #Etymology

Words you wouldn't guess are etymologically linked.

An ongoing, continually updated thread 👇🏻

Medicine and remedy both come from the Latin verb medeor, meaning to heal.

Medicine comes from the Old French medecine, from the Latin medicina meaning medicine.

Remedy comes from the Old French remede, from the Latin

Feminism, fawn and fetus both come from the PIE root *dʰeh₁(y)-, meaning to nurse or

Pine (tree) & Piñata (papier-mâché container) both come from the Latin pinus—meaning pine.

Piñata (Spanish), came from piña meaning pineapple, as the paper-covered box resembles one. Piña comes from the Latin pinea meaning pinecone (derived from

Whiskey and wash both come from the Proto-Indo-Euro root meaning "water; wet."

Whiskey (Irish uisce beatha & Scottish uisge-beatha) literally means "water of life."

Wash cames from the Middle English weschen, meaning "to

Now, what exactly is an applied epidemiologist, and why are they needed? In the late 90s- early 2000's there were a series of articles in AJPH, AJE, JECH, and IJE dedicated to answering these questions. I'll focus on Stephen Thacker's review.

He states, “The applied epidemiologist is by definition an activist, moving rapidly from findings to policy, putting epi knowledge to good use. The 21st century epi must do all these things while maintaining a foundation of high-quality epi research and practice.”

Susser warns the field of what he considers “the black box paradigm… the current international focus on risk factor epidemiology.” He advocates for expanding our academic training to include socializing epis to “keep the improvement of the public’s health as a primary value”

Morabia argued that epidemiology has historically found its balance in the tension between the search for causal relations and the improvement of public health; overemphasis on either perspective puts epidemiology at risk of losing its value.

How does this play out in real life? I’ve been an applied epi for 13 years, working mainly in local, state, and federal health agencies. My work has focused on conducting cool analysis that lead to policy or systemic change.
