An A-level eye-opener

There is a general perception that A-levels ain't what they used to be. In my young day, when the world was right and the sun shone all summer and the streets were paved with orphans who were grateful for the work, that's when an education was a real education. You couldn't pass a physics exam by drawing a picture called "How I feel about electrons". The youth of today blah blah blah rant foam (to paraphrase the Daily Mail).

For those not conversant with the UK system, A-levels are "Advanced level" exams, usually taken at age 18, and required for entry into university. We university physics lecturers see the results of the school education system and, based on our impressions of each year's freshers, we too make assumptions and guesses about the state of the A-level system.

All the physics lecturers in the house say, "hey!"

I can't hear you! It's always important to have an idea of the audience for whom one is writing and, in my own experience of a normal working day, I've noticed that most adults are university physics lecturers, but I'm willing to entertain the possibility that my experience might not be entirely typical. Well, even if you happen to be one of those non-physics lecturers that I've heard about, the current standards of education are obviously important to you too because (a) you don't want your own hard-won qualifications to be devalued, and (b) today's schoolchildren will soon be building nuclear power stations, fighting world-hunger, and cleaning the dribble from our wrinkled chins.

So, you might be interested to know that, rather than continuing to speculate about A-level standards, last week I went to see for myself, spending a day sitting-in on science lessons at South Cheshire College, at the kind invitation of Head of Physics, Dr Phil Klein. It's a Further Education college teaching A-levels, vocational training and adult HE-access courses to a vast number and variety of learners. My first impression of the college's two-year-old £70M building was that it felt simultaneously light and spacious yet intimate and comfortable, and this was a triumph of design, considering that the institution was way bigger than any school or FE college I had previously visited. If its role-call of 300 doesn't sound huge, that's because it's just the number of teachers.

But there was no hint of the enormity of the place, or of the social deprivation in surrounding catchment area, as I attended the calm, orderly lessons in which the teachers had a friendly rapport with each of the dozen-or-so students. The first lesson, A-level physics, was closest to my heart and the main purpose of my fact-finding mission.

I had arrived with an open mind, but must admit that I expected to be horrified by a superficial syllabus, much diluted since my own sixth-form career in the late nineteen ahem-ties. (Excuse the frog in my throat; it's decrepit.) My smugness was instantly crushed, as I was confronted by a discussion of nuclear decay pathways that had me dredging dim memories of undergraduate lectures. Far from being watered-down, the syllabus has been extended to include serious stuff about subatomic particles and astrophysics. Meanwhile, I was delighted to discover that the vital foundations of the subject have not been abandoned; Newton's laws of motion, force balance and discharging capacitors are still covered in rock-solid fashion.

"It's all very well optimistically writing these topics into the national curriculum," I hear you say, "but do the bright young things actually understand any of it?" The exchanges that I witnessed, between teacher and pupils, convinced me that, within those Cheshire walls at least, there was no shortage of expertise. For instance, having worked though some algebra on the whiteboard, the teacher asked the class, "What's the best way of plotting a graph to demonstrate a power-law formula?" and I was impressed when several of the youngsters simultaneously replied,

"Log-log plot." In case that phrase is not redolent with meaning for you, I should point out that they were right, and that the log-log plot, while being one of the most useful weapons in a scientist's arsenal, is not at all straightforward to understand.

It would be misleading to claim that the future of sixth-form schooling is entirely rose-tinted. There are two blots on the exam boards' copy sheets, of which everyone who has followed their progress over the last twenty years is aware. The first is the well-known and undeniable phenomenon of grade inflation, that was an inevitable result of taking the exams business out of the hands of University boards, and into the mitts of profit-making companies, that tout for trade on the basis of their results.

The second is a subtle change in the nature of physics A-level exam papers that worries those of us who pick up the teachers' baton at university. The questions are still of the same standard and depth as ever and, as I say, of even greater breadth. But the answers, which used to be written on simple A4 lined paper, are now written into a pre-printed booklet, in which the appropriate diagrams, construction lines, and general shape of the answer have already been sketched out. This leaves the student with no opportunity to practise the crucial skill that we physics-types call "problem-solving". That is to say the spark of insight and invention required to take the cryptic description of a problem, choose how to approach it, and convert it into a sketch and subsequent calculation. The young people I met last week undoubtedly had the nous to find their own way to solve complex problems, but need to be given more practise at this skill during their formative years at school. In spite of this fly in the ointment, it filled me with relief and optimism to see such motivated, self-disciplined and well-informed A-levellers.


  1. Because of its control of currency markets and banks through money related arrangement, the Fed impacts loan fees, resource costs, and credit streams all through the budgetary framework. Arbitrage and rivalry spread increments or declines in loan costs under the Fed's immediate control to different markets including, obviously, land. Car Title Loans

  2. Trader advance suppliers offer an other option to bank advances that are a quick and simple route for organizations to get working capital when they are confronted with restricted choices. payday loans

  3. A business depicts the "picture" of achievement superior to anything a man does. This is a direct result of that, that loaning establishments work better for those agents. As a sole proprietor, a man "shows up" to act to their greatest advantage as a person rather than a business. check cashing

  5. Attempt to Base Your Business at Home: This is impractical for everything except in the event that you can have a locally established business you can really spare a fortune. You save money on costly business lease, which is a repeating cost. check cashing

  6. When you are thinking about the benefits of different sorts of advances you can profit, you have to consider loan fees which would apply. Charge cards actually have a higher rate of enthusiasm than advances. Besides, making utilization of individual credit to bolster a business is hazardous. On the off chance that at all the business you began bombs, then you would harm all your credit and you will be left not a lot for your future. cash advance corona
