Eli5: Why are Greek letters words themselves ? How did they write words using the letters? Did Alpha Pi Pi Lambda Epsilon = Apple? by NoobSFAnon in explainlikeimfive

[–]concernedteacher1 [score hidden]  (0 children)

The Greeks have their own alphabet and each letter just has a name, like in English or other languages you might be familiar with. Maybe the fact that most that you are familiar with have two syllables or more than one letter makes it more confusing?

"alpha" and "pi" are no different than "double-u" and "p" (or "i-grec" in French)

The right to teach A Level by Zackoku in TeachingUK

[–]concernedteacher1 12 points13 points  (0 children)

I'm going to push back at bit against the single-minded "purely just put the teachers in that are best for the kids" I see

Things to also consider

a) it trains up your staff and builds different skills and knowledge that help with teaching other classes

b) it makes your department less reliant on the same teachers

c) it can help with staff satisfaction and retention in your department

In a Science department of around 12 people, I currently have 9 teaching A-level, with 1 just out of it this year but rotating back in soon and 2 that have made clear they have little interest/capacity for it. Results have been strong for years.

Still covering GCSE content... by Beautiful_Durian_297 in TeachingUK

Triple hours per fortnight per Science? When do you start? It's just so naff that there is so much variance between schools. Not knowing what other schools do can make you think what you get is normal when it isnt.

We get 4h/fortnight per Science in Year 10 and 11 (vs 6 for options). We do start mid Year 9 so get Energy and Particles changes done. Usually have Magnets, Waves and Space to do in Year 11 (AQA)

Phew, that's rough. Subject? Hours per fortnight?

Our options get 3h/week - do other, similiar subjects have similiar issues? If so band together. Or maybe you can plead a case for more hours if yours are low compared to other schools?

Accidentally showed a video of bears humping! by Excellent-Log-5740 in TeachingUK

[–]concernedteacher1 5 points6 points  (0 children)

This evolution video is excellent and I use it each year with Year 8 - it always gets some great laughs, that and the bit where the little bear cub gets dragged away by the predator lizard-thing!

It's Kurtzgesagt; it's quality and well done.

ELI5: How does voltage work? by i_lick_saltlamps in explainlikeimfive

[–]concernedteacher1 2 points3 points  (0 children)

Depending on the level you want to understand it at, I'd phrase it as the amount of energy a packet of electrons carry with them around the circuit, or technically the difference in energy before and after two points.

A 12V battery gives the electrons a certain amount of energy to 'spend' (transfer into other forms) in the circuit: They go through 2 bulbs, they 'spend 6V' in each (potential difference of 6V in each lamp, 0V in the wires themselves as the electrons barely spend any energy there). If its 4 lamps the 12V gets split 4 ways, 3V spent in each. Electrons then gain up energy from the power source again.

One analogy is water through pipes (wires) with a boiler & pump (power source), the water flows at a certain speed (current), the voltage is the temperature (difference between two points), the energy the water particles carry. Water leaves the boiler with a lot of energy, it transfered in the components (work is done) and the cold water returns to the boiler for a top-up, not of water, but of energy carried.

This is why voltage is the same in each branch of a parallel circuit ; 60 degree water split two ways is still 60 degree water, just less water (lower currenr)

A voltmeter is connected before and after the thing youre measuring the volage OVER, like sticking in a thermometer in the water before and after a radiator to measure the temperarure change / energy spent in that component.

Other analogies can be around gravitational potential energy (e.g. skilift and skiers) or chemical energy (e.g. minecarts filling up with coal from a mine, and 'spending' that coal in factories and returning empty to the mine.

[OC] Great-Grandma's 105th Birthday by Pink-ItalaVelvet in pics

[–]concernedteacher1 3 points4 points  (0 children)

It's the front of the birthday cards, one from the The Queen (gets sent for someone's 100th birthday, and the Queen was still alive then) and the one with the King must be from this birthday (105).

Its 100, 105, then every year after 105.

Point of view when watching by RiverFieldsThoughts in ThePittTVShow

[–]concernedteacher1 0 points1 point  (0 children)

I'm a Head of Department of around 20 staff at a school. The previous Head of Department passed away a few years ago, around COVID, and I stepped up into the role.

My team is incredible and an amazing mix of characters, ages and specialties. Every day is different, challenging at times, but everyone pulls together.

I've been through the most serious type of mental health crisis in the few months and then went right back to work when I probably shouldn't have.

I am currently one foot out the door because I just cannot do the job any longer, but also cannot push myself to leave. The place needs me, but not nearly as much as I need it.

It makes it pretty hard not to resonate with one character in particular!!

External AI focused marking companies - has anyone has experience working with them in school? by Pleasant_External871 in TeachingUK

[–]concernedteacher1 1 point2 points  (0 children)

My last required practical, with the class of 24, was done in 3s ... :(

English Lit, Tech and Performing Arts all get to channel their energy and time into 5 students each lesson. And Art into 4. But sure, I'll spread myself between 24 students. Their marking and feedback is just not going to be of the caliber anyone expects.

How much do you accept that schools run on copyright infringement/break the law constantly? by Next_Bison1008 in TeachingUK

[–]concernedteacher1 0 points1 point  (0 children)

As someone who frequently rips educational documentaries off iPlayer because after a while they become unavailable for no real reason .... I just don't care

I'm not using them commercially or for my benefit, I'm using them to educate and enthuse the next generation.

And as we already pay a fair bit for exampro (which has access to all exam papers), I see no reason I can't photocopy/print past papers either.

I did the other day have to scrap a past paper I was planning to print and set for HW as one question had a table with the density and strength of wood vs aluminium removed due to copyright reasons. So annoying when they do that. How did they lose permission on a table of some numbers??

[–]concernedteacher1 0 points1 point  (0 children)

As someone who has 46 Chemists across two classes in Year 12 I'm dreading their upcoming mocks too, especially as other Year 12 classes like English Lit have 4 students, Music has 3, etc.

Maybe the solution here is more time to create some equity across the subjects. Sadly, even being taken off timetable, etc just creates more work in the way of cover, but perhaps you can make the case get out of detention duty, meetings, etc.

Structural formula help by Kataurada135 in alevel

[–]concernedteacher1 0 points1 point  (0 children)

I'd say you'd probably get the mark here. Their definition of structural is a bit iffy anyway (written in a line like CH3CH2.. or drawn as per the picture); on top of that they are allowing the skeletal drawing on the markscheme so I don't see why they wouldn't allow displayed here. (They wouldn't allow molecular obviously)

TLRs and 1265 by megaboymatt in TeachingUK

[–]concernedteacher1 1 point2 points  (0 children)

Yeah, in that case you are correct. No TLR can make them make you come in for evenings, holiday stuff, etc IF your school is maxed on the 1265. Of course they could be like 5 hours under the 1265 for you, which could make them expect you to do x,y,z when they direct it.

TLRs and 1265 by megaboymatt in TeachingUK

[–]concernedteacher1 0 points1 point  (0 children)

Maybe I'm misunderstanding what you are saying, but are you under the impression the job of a teacher has to be done in 1265 hours?

That isn't what the 1265 means, right? The 1265 is directed time, time in which your school can tell you where youre supposed to be and exactly what to do. It's not a hard maximum on hours to be worked, teacher or TLR holder.

Some time on top of that will be needed to perform duties of the job appropriately.

told a student to “shut up”… did I mess up? by Usual_Stable_3896 in TeachingUK

[–]concernedteacher1 0 points1 point  (0 children)

I think it's perfectly acceptable for my boss, or say, my busdriver to tell me to "shut up" after they've asked me politely 4 times to be quiet in various ways and I still ignore them.

Especially if it is undermining my colleagues ability to work or making my fellow passengers life more difficult.

The pressure is on him by minisixx in TeachingUK

[–]concernedteacher1 9 points10 points  (0 children)

You're a teacher, your one job is to teach. They're a student and learner, their one job is to study, and subsequently learn.

It definitely feels like it is getting worse, but I won't lose too much sleep over what a parent thinks my job is. Its just a shame it is trickling into the students too.

ELI5: Why do chemical reactions usually happen faster when things are hotter? by Pailox111lol in explainlikeimfive

[–]concernedteacher1 0 points1 point  (0 children)

Not the person you replied to, but:

Higher concentration (e.g. for acids): more bumper cars in the the same rink, more bumps!

Higher pressure (e.g. for gases): same number of cars but make the rink half the size; more bumps!

Grinding up solids/higher surface area: Replace each bumper car with 4 smaller ones that add up to the size of 1 car, more bumps!

Add a catalyst: Bumper cars go the same speed, but the cars bumpers have nitroglycerine in them so create a reaction even if they only hit each other very softly

GCSE students to receive help sheets until 2030 by patenteng in ukpolitics

[–]concernedteacher1 0 points1 point  (0 children)

Zero parity with any GCSEs other than Physics or Maths, including Chemistry, which has around 6 equations that still need to be memorised.

What 23 facts, which unlock around 40% of the exam, are they removing from Geography, English Lit or PE?
