Ed Balls Shocked by My Question

Ed Balls shocked by Glen's questionSince the Schools Secretary has failed to answer any questions I've addressed to him in posts, I submitted a question to Sarah Ebner's blog over at the Times. She had managed to get Balls to join a live Q&A session and had asked for questions to ask his. Needless to say, the slimy minister read all the questions and proceeded to answer the ones he had prepared earlier, in true Blue Peter style.

The full discussion is here , with my question down at times 14.02 to 14.05. The accompanying photo, captioned http://www.timesonline.co.uk/tol/comment/live_debate/article7012253.ece is reproduced here — does he look shocked at the quality of the question?

The edited sequence goes like this:
14.02 Sarah Ebner:
This is another point which comes up often on the blog. Glen asks: why persist with judgements of schools based on raw percentages of students achieving 5 grade C GCSEs? It penalises schools serving deprived areas - schools which need a hand up, not a kicking. It also pressurises schools to focus on grade D students, and encourages entries into easier ICT online courses and such like.

14.05 Ed Balls:
Sarah, you are completely right and so is Glen, as parents we all have to look at the current league table and try to work out what they really mean on the basis of what we know about the school itself, the catchment area etc. And league tables can sometimes suggest schools are 'high achieving' when they actually do a poor job at raising standards and supporting progression. Our new Report Card is designed to give parents much more information - about raw results but also whether all children make progress, discipline, parent satisfaction etc. I think it will be much fairer and more informative - it will be in all schools over the next 2 years.
So, I had asked him about the huge pressure that the government and Ofsted puts, often unfairly, on schools in difficult circumstances, distorting their priorities, and he answers an imaginary question about league tables!

OK, he did that to all of the questions, but then why did he bother to travel to the Times offices, just to act as if he were in the House of Commons (not) answering questions put to him there?

Election Poll News: No Change Really

Looking through last week's papers (our paper delivery boy made it through all the snow disruption last month, but seems to have forgotten today now the weather's fine and the sky is blue) I found a story I had missed.

The small front page story started with
“Gordon Brown has insisted Labour could still win the general election outright as another poll showed the Tory lead narrowing.

Research by ICM for the Sunday Telegraph put David Cameron's party down one point since last month on 39%.”
I know it might indicate something about my personality type, but the story irritated me. Down one point, with a sample size of a measly thousand?

Now, results of course vary from sample to sample in a predictably random way, which puts a limit on the reliability of any judgements made from the data from just one sample. But how much? Trust the data to within 0.1%? Or 10%?

Here's the maths bit — skip to the next paragraph if it's not your thing.

If the poll results over time can be represented approximated by a Poisson distribution (a reasonable assumption), then the variance of the number of people preferring one party is equal to the mean number of people choosing that category. For opinion polls, we don't know this mean, but it is close to the reported figure, i.e 39% of 1002 in the sample. With this variance, we can be about 95% sure that the true mean number of people in repeated samples choosing Tory would be 390 (40%) plus or minus twice the square root of the variance (about 40 votes, or 4%).

And the result is:

So the real result is "The Conservatives polled between 35% and 43%, which is consistent with no change at all." OK, not a good headline, but even newspapers have an obligation to at least try to be right. I'm sure papers used to put this sort of information at the foot or the article (where hardly anyone would see it), even if the article writer ignored such a basic check. But to have every outlet from newspaper to the TV news run a similar story is laziness.

Every newsroom must have someone with enough maths skill to do this right, haven't they?

Mass Produced Target Grades

Sixth form students will by now have dragged themselves through the January exam series. They can relax until scores are released in March, when most will be judged according to their college 'target grades'. And it is likely to be a miserable experience for most.

I used to talk to my students and get to know their individual strengths and weaknesses. I would encourage those who I perceived were studying hard, and chide those who were just attending class without the necessary intellectual engagement. Reports to parents and managers were based on my professional opinion of each child. But not any more.

Teachers still get to know each of their charges, but their professional judgements are now routinely tempered by the knowledge that performance against their grade target trumps all other information.

Value Added

Target grades are now the ubiquitous tool of comparative assessment in schools: Key Stage 3 results are used to predict GCSE grades, while GCSE grade averages are used to compute the most likely grade a student might achieve at A Level. This is a very good process for working out if the school is doing a good job, since if a year group cohort gains a mean score above the mean predicted grade, then the group has learned more than could reasonable been expected. The school thus has recorded some value added, in the language of education.

Using the same data for individual teachers is only likely to be reliable over a period of several years, since the sample sizes from individual classes are much smaller, leading to more variation from year to year.

Blinded by Numbers


The big problem stems from applying these statistics to individual students. It is very easy to calculate an expected grade from a single child's previous achievement, but with a sample size of just one, the precision is poor. The reliability stemming from a cohort in the hundreds is lost, and the prediction is routinely in error by a whole grade or so. (See my post Physics Exams Too Easy, Says Ofqual

Now, this would not be a problem if these figures were just another piece of the puzzle to be understood by the teacher, but OFSTED, the government overlord of teaching standards, thinks students should know these rough predictions, and be challenged to achieve them. And leaned on if they don't come up to scratch.

Once upon a time, I got to know my own students, and made judgements as to their individual abilities and potentials, and assessed their effort accordingly. Not perfect, but at least both teacher and student were in the loop.

Forget the Child – Press the Button and Set That Target

Now, each student is given a grade to achieve by the end of a two year course, during which they will mature and develop. If they are very lucky, they will get several target grades which take into account the historical difficulties of each subject they are studying. If not, as is happening more commonly now, they will get a single grade to span the range from Photography and Media to Chemistry and Maths. And to make the target aspirational, a grade will be added to ensure that only a quarter of students will be able to meet their targets, with poor reports and disciplinary procedures for those souls unlucky enough to keep missing impossible targets.

Advantages
  • Simple and cheap to operate.
  • Keeps OFSTED happy.

Disadvantages
  • No educational merit.
  • Can turn keen students into serial target-missers.

An open and shut case for school managers. Shame about the children.

Government Buries 'Good' News

Even though the new Academies have done so well in last summer's exam period, the government can still not bring themselves to publish usable comparative data to prove the case.

The recent publication of the GCSE and Equivalent Results in England was accompanied by a government press release which declared:
“Even more encouraging is the clear fact that children who have faced the most challenging circumstances over the past 12 years have not been cast adrift and left at the bottom, but thanks to the Academies, National Challenge and City Challenge programmes have actually seen a more rapid improvement in results than those in the least deprived areas.”

Concerns

The biggest concern with the steady and dramatic increases in the figures, after grade inflation, is the widespread tactic of entering weaker pupils for the laughably easy vocational courses that have 'GCSE equivalence'. For example, half of all schools enter almost everyone into the vocational ICT course instead of the more challenging GCSE ICT, as it can be completed in one year and can be worth anything up to four GCSEs at grade C or above. The Telegraph reports:
A report last year by Ofsted, the education watchdog, found that qualifications such as the one run by OCR were “less demanding” than other mainstream exams. It said pupils were able to pass “whether or not they had understood what they had done”.
It is true that the number of students nationally that gain 5 A*-C grades is only 3% less if you exclude the 'equivalent', vocational courses, but there are categories of schools which have a lot to lose if their pass rated don't improve sharply.

Schools Minister Vernon Coaker's press-release said that the new Academies A*-C grades had increased at double the national rate, so I looked at the accompanying data.

Sneaky Tricks

The data looks comprehensive, and even breaks down results for different types of school and with/without the vocational courses. The time series do indeed show Academies improving faster then any other major category of schools, but the figures for the Academies without the vocational courses are missing!

Vernon's minions emphasised the Academy raw percentage increases, but rolled their key data in with that for comprehensive schools, making it impossible to see what effect the dash for vocational courses has had.

Since it is just these schools that are most desperate to bump up their figures quickly to avoid the Wrath of Balls, it is very suspicious that the data, which was released with some fanfare, should have been airbrushed like this. What is the government afraid of? Given the obsession of the government with media manipulation, one can only assume that Academies have achieved their politically essential successes through a choice of courses that benefited the school more than their unfortunate pupils.

Rationalising Christmas and New Year

What exactly are we all celebrating? We stay up later than normal, flipping between lots of TV channels with little to watch (Jools' Annual Hootananny is not my thing), and drink several times what our Nanny Government says is a sensible limit. But only because one of the numbers in our Gregorian church calendar system goes up by one.

Now, years are natural units, based on measurements of the seasons or the stars, but the start of the calendar year is arbitrary, and depends on political and scriptural judgements in Rome over the last couple of millennia.

I agree that midwinter festival is good to have, to mark the passing of the darkest days, but we in the north already have one in Christmas, and it is midsummer for our upside-down friends in the southern hemisphere. So what are we celebrating on New Year's Eve, if not an even more wanton and self-centred version of Christmas, but with the present giving replaced by excessive drinking?

And having Christmas and New Year so close together also takes a whole week (or two) out of the economy and causes office discord in the annual rush for the key leave dates.

Moving Christmas to the Spring Equinox would solve a lot. It would give an excuse for the non-Christians to join in, and could be argued on Biblical grounds even if it would interfere with the dates of Easter — shepherds watch their flocks all night during lambing season, don't they? But I don't see the major Christian denominations agreeing to such a big change, even if it would leave New Year as the single centre of the midwinter festivities.

If the Spring Equinox Christmas is out, how about the Winter Solstice? It was origin of the current date of Christmas since the pagan celebration of Yule-Tide was held on the 25th December, the date of the Solstice in the old Julian Calendar. Looking around at the fashion for lighting up the outsides of houses with glowing Santas and moving, lit-up reindeer, most of the celebrations around this time of year are strictly secular already, so reuniting Yule and Christmas on the same day on the Solstice would fit the multicultural, inclusive theme of the last decade of insipid politics.

What to do with New Year, now that we have sorted Christmas? I'd move it to the Spring Equinox, when the weather is warm enough for me to want to go out in it. But I go out for a drink on the Equinox anyway, so why would I need a calendar justification? Let's just leave the New Year booze up when it is, so all the young partying types can go out by themselves and get cold and drunk, without expecting me to join in.

So I'll be sitting at home in front of the TV, flicking channels while the fireworks go off all evening, drinking some wine, looking forward to the longer and warmer days to come.

Cheers!

Tories to Ease Physics Teacher Shortage, while TDA Says All is Rosy

Shadow Schools Secretary Michael Gove has said that a Conservative government will exempt good physics (and science and maths) graduates from student loan repayments if they go into teaching. The Training and Development Agency for Schools (TDA), meanwhile, has muddied the waters by claiming to have exceeded its targets to recruit and train teachers for all main shortage specialisms.

The teacher training quango has managed to massage the teacher recruitment figures to disguise the shortage of physics teachers in schools, by failing to set a target for their recruitment. The TDA reported that “for the first time ever” recruitment to all main specialisms has exceeded their targets and that “a healthy supply of well-trained teachers is entering our classrooms.”

The total number of mainstream registrations of Science teachers did indeed rise, by 1%, from 3655 last year to 3701, although to claim that the target of just 3405 was exceeded “by as much as 9%” seems to be over-egging the results a little.

The key omission, though, is that there is no target for physics teachers at all! Their numbers declined from 584 last year to an estimated 571. Bang goes the government target of having physicists making up a quarter of all science teachers by 2012. With a quarter of current physics teachers already over 50 and keen to retire, this target looks as far away as ever.

(See here and here for my previous comments on physics teacher shortages and the solutions, and on Gordon Brown's pontifications here.)

The Conservatives, though, look like they at least recognise the seriousness of the problem.

In a speech to the Sir John Cass Foundation, Michael Gove said
“We will make a new offer to people - similar to something President Obama wants to do. If after leaving school someone decides to do a maths or science degree at a designated university, achieves a 2:1 or First, and decides to go into teaching, the taxpayer will cover their student loan repayments for as long as they remain in teaching (until the loan is fully paid).”
This could be worth £40k to a teacher whose pay cannot otherwise be increased beyond that offered to other, less scarce, specialisms.

The Institute of Physics has welcomed the initiative, noting that that
“Children in approximately 500 secondary schools across the country have no teachers with experience of physics beyond school.

“This means too many students being taught physics by teachers who may not even have taken the subject at A-level. How can students be inspired by teachers who themselves have no solid grasp of the subject?

At Least I'm Not Bored!

I am up to my neck in coursework, annual appraisals, parents' evenings and open days, in one of those months that make up for the long lazy holidays. So it is nice to know that teachers are the least bored workers in the country, according to a three year old survey I just found (note to the TDA - your press releases are not getting much attention!).

While researchers are in sixth place in the boredom stakes and engineers only marginally better in eighth, teachers report the lowest amounts of boredom of all graduate professions.

The full list from the Training & Development Agency for Schools' Boredom Index:
  1. Administrative/secretarial (10 out of 10)
  2. Manufacturing
  3. Sales
  4. Marketing/advertising
  5. IT/telecommunications
  6. Science research/development
  7. Media
  8. Law
  9. Engineering
  10. Banking/finance
  11. Human resources
  12. Accountancy
  13. Hospitality/travel
  14. Healthcare
  15. Teaching (4 out of 10)
The press release adds:
When asked why they find their job interesting, 81 per cent of teachers questioned said it is the challenge of the role, 81 per cent because no two days are the same, and 86 per cent said they enjoy the interaction with people. Sixty-four per cent also rate the opportunity to use their creativity.

Employees surveyed say they are mainly bored because of the lack of challenge in their jobs (61 per cent), whilst not using their skills or their knowledge makes life tedious for 60 per cent. And boredom through doing the same things every day (50 per cent) is also to blame.
You might ask yourself how I found myself browsing through three year old press releases when I'm so busy …

Two Cultures in New Science Map

Students can find it hard to know what areas of science are actively researched, especially since much of what is taught is so ancient and established (But Physics A Level now has a token Quantum Physics section, and that's less than a hundred years old!). A new study may help.

The PLoS ONE online journal has a paper presenting a map constructed from over a billion user interactions logged by journals' web portals (so-called clickstream data). The result is a beautiful whirlpool shaped image, showing the links between different research areas throughout the sciences, humanities and social sciences.

There is a worryingly large gap between the sciences and the humanities; Snow's Two Cultures are alive and well worldwide, and not just in Britain, since the data used is global. The Royal Institution is holding a lecture this week entitled CP Snow's 'Two cultures': 50 years of debate. Bath psychologist Professor Helen Hast will “explore the paradoxes of "value freedom" within such a highly morally-charged perception of both the pursuit and purposes of science - and some resistances to it.”

The RI page for the talk says that the is good availability for tickets. Quite so.

Claims of HIV Vaccine Success are Premature

HIV vaccine
The excitement is palpable — the vaccine that nobody thought would work “appeared to lower the rate of HIV infection by 31.2 percent compared to placebo ”, according to the press release, although printing all three significant figures sets my inner sceptic on edge.

The BBC story improved things marginally, reporting a rounded percentage:
“Scientists announced last month that a combination of vaccines gave a 31% level of protection in trials among 16,000 heterosexuals aged 18-30.
Doubts had been raised about whether the finding was significant.
But new data published at a conference in Paris indicates that, while small scale, the findings are robust and statistically significant.”
Exciting, but while statistically significant sounds very scientific and reliable (the results were published in the New England Journal of Medicine (NEJM) no less), the journalists should have read the report itself. The figures reveal a little sleight of hand.

The study randomised over 16 000 people to either the vaccine program or a placebo, with none of the participants knowing what they had (a double blind trial — the best sort). The randomisation here is key, as the study was rather underpowered and was only likely to produce a marginal result at best, and any deviation from this randomisation may have introduced biases that were hard to spot.

The researchers actually carried out three statistical tests on the data from the trial: intention to treat (ITT), per-protocol and modified intention to treat (mITT) analyses. The first two look at those participants who were enrolled (ITT) or completed the treatments (per-protocol), and so preserve the randomisation of patients. These both failed to show a statistically significant benefit from the vaccine.

The mITT process removed several people from the analysis, both breaking the randomisation and producing a statistically significant result. This might have been useful if the vaccine had a clear benefit, but the published benefit was not 31.2% exactly. Rather the confidence interval for the benefit (the range in which the researchers were confident that the true benefit figure lay) was 1%-52%, with the lower bound only staying positive because of the arbitrary choice of 95% confidence intervals chosen by statisticians over the years.

With the two tests that avoided the possibility of bias getting ignored by the press (since they didn't make the press release), and the remaining result showing that the vaccine could have had no actual benefit, the publicity seems a little unjustified.

Has Teacher Pay Really Improved Under Labour?

With the Chancellor of the Exchequer, Alistair Darling, signalling a public sector pay squeeze, and the ever more political and activist head of the Audit Commission quango, Steve Bundred, recommending a pay freeze as “a pain-free way of cutting public spending”, it is worth looking at the figures to see how much teachers have really benefited from government largess during the boom years.

The answer, in case you don't want to read to the bottom to see the graph, is not at all!

Bundred wrote in the Observer last Sunday:
“let's dismiss the notion that spending on health and education will be protected. There are good reasons why they won't and shouldn't. One is that, at a time when inflation is likely to be between 2% and 3%, a pain-free way of cutting public spending would be to freeze public sector pay, or at least impose severe pay restraint. This is especially true if real wages in the private sector are still falling.”
adding a political stance with:
“Health and education will not be immune from pay restraint, partly for reasons of fairness to others, … and also because ministers will correctly assume that as public sector workers have done well over the past decade, they will tolerate some modest real reduction in earnings.”
This is misleading in two ways.

Wages Are Not Falling

First, although pay growth has slowed, wages are not falling. As Ken Mulkearn of Incomes Data Services wrote in the Guardian, the reported negative private sector pay awards are skewed largely by the loss of bonuses in banking:
“The data for April 2009, using figures not seasonally adjusted and excluding bonuses, shows earnings growth of 2.5% in the private sector and 3.3% in the public sector, consistent with IDS research on pay settlements. In the private sector, the official figures show manufacturing (where most freezes are) at 1% and private services at 2.9%.”

Teachers Have Not Seen Pay Rise

Second, teachers have not done well out of the last decade, despite repeated claims from ministers and the uncritical acceptance of this factoid in the media. The graph shows an index of how (sixth form) teacher pay, which has been largely pegged to school teacher rates, has increased compared to the All Items Retail Prices Index. I start at 2001 as that is the earliest data I can find from the teacher union websites.Clearly, our pay moved ahead of inflation for the first couple of years, but since 2004 there has been steady slide. Not bad, but we've hardly “done well over the past decade”

What? Ministers are Being Deceitful?

Now, I don't mind joining in on a general belt-tightening, but at least I would like my pain to be recognised — I can't bear to have the millionaire ministers looking down their patrician noses at me, feeding me lies about my own pay and telling me that I should be grateful to have had it so good.

How to Choose a School

Once upon a time, secondary schools had catchment areas and feeder primary and middle schools. The parents' role was simply to aid the transition and buy a new uniform and pencil set. Life was simple. But not now.

There is a bewildering range of information available about schools, from the percentage of GCSE A* to C to the school's Index of Multiple Deprivation and Free School Meals, as well as the Open Day visits. However, the complexity of the data masks the main truth that the story it tells is simple and not so hard to judge.

It boils down to this: will your child raise the tone of the school or be raised by it?

League Tables

First, the league table figures you see in the broadsheet newspapers are easy for schools to massage, and they rarely tell you anything you didn't know any way.

Everything from entering pupils into easy online IT course and vocational BTEC subjects, officially worth several grade C GCSEs each but with a much reduced challenge, through to picking out a couple of dozen lazy grade D boys and squeezing them until the pips squeak and they get a clutch of grade Cs. Coursework regulations, intended to ensure that only a pupil's own work is submitted, are routinely ignored, with substandard work repeatedly marked and returned until it is good enough. Schools will even switch exam boards to chase those examiners that 'grade high', often following the appointment of a new head teacher looking to quickly make their mark.

These dodgy practices are sometimes apparent in the figures as a series of sudden jumps in the A* to C rates, as each new trick comes online, when even brilliant changes should take some time to feed through as new pupils move up the school with a new system.

A Social Measure

The league tables do, however, tell you much about the economic background of the families whose children make up a school's population. If you compare the league table with the ranking according to the government's Index of Multiple Deprivation (IMD), you find they measure substantially the same thing. A school high in one list will be low in the other. (For those interested, the rank correlation is around -0.75, at least in my county). The IMD accounts for around half of all the differences between schools in the tables, which makes it a more important measure than any other single factor.

So league table position, GCSE A* to Cs, and all that complex data tell you little more than you could find out from parking near the school and watching the children as they pile out at the end of the day. Posh or rough? And if you are applying to local schools, then you already know their social make-up.

Ignore the Flashy Talk

Ignore the head teachers' Powerpoint presentations, where they tell you that the school is more than just a few numbers but here they are anyway, and go on a tour around the school. (However, a really poor presentation can tell you something about their attention to details.) Talk to the tour guide and talk to pupils you find in the corridor. Peer into any classroom with the door closed, and see what the children are doing when they think they're not being watched. Talk to the teachers, but not about the school, since they will be on their best behaviour and supporting their employer — ask them about themselves and their job. Teachers spend their days talking, so get them talking about their days and experiences and be interested in them. Are they at home and comfortable in their jobs, do they travel for to be here, and do their own children attend the same school?

Culture

The league table position tells you how the school did with the mix of children they had, but it tells you little about how your child will do. So the real question is: can you see your own child fitting in with the children you have seen there?

It is not the prefects who showed you round you should be watching, who really ought to be smart, but the surly ones who've found their way to the corner on the back row of the class. There will always be some, but if there is more that a few in each room the teachers' jobs become much harder and the easy children get less of the teachers' attention.

The task of choosing a secondary school has become very complex if all the school gate discussions are to be believed. But, in reality, the judgement to be be made can be made without reference to all that conflicting and compromised data $mdash; just try to picture your child in amongst those who you see in the classrooms and corridors.

Will your child raise the tone of the school or be raised by it?

On Keeping Gimmicks Out of the Classroom

David Griffiths, Reed PhysicistHaving resisted all manner of education gimmicks and fashions that have been thrust at me by well meaning college managers, it was refreshing to read the latest piece written by renowned undergraduate textbook writer and educator, David Griffiths. Published in the IoP magazine Physics World, Griffiths reminds us that Physics sells itself to students if presented honestly:
“Physics teachers are fortunate (I am among friends, so I can speak frankly): ours is a subject the relevance and importance of which are beyond question, and which is intrinsically fascinating to anyone whose mind has not been corrupted by bad teaching or poisoned by dogma and superstition. I have never felt the need to "sell" physics, and efforts to do so under the banner "physics is fun" seem to me demeaning. Lay out our wares attractively in the marketplace of ideas and eager buyers will flock to us.
“What we have on offer is nothing less than an explanation of how matter behaves on the most fundamental level. It is a story that is magnificent (by good fortune or divine benevolence), coherent (at least that is the goal), plausible (though far from obvious) and true (that is the most remarkable thing about it). It is imperfect and unfinished (of course), but always improving. It is, moreover, amazingly powerful and extraordinarily useful. Our job is to tell this story – even, if we are lucky, to add a sentence or a paragraph to it. And why not tell it with style and grace?”
He goes on to criticise the gimmickry that is supposed to gain better attention from students. He has this to say about the advent of flash cards and electronic clickers:
“They can be powerfully effective in the hands of an inspired expert like Mazur, but I have seen them reduced to distracting gimmicks by less-capable instructors. What concerns me, however, is the unspoken message reliance on such devices may convey: (1) this stuff is boring; and (2) I cannot rely on you to pay attention. Now, point (2) may be valid, but point (1) is so utterly and perniciously false that one should, in my view, avoid anything that is even remotely open to such an interpretation.”
The point is made that any new approach to teaching will produce measurable improvements, but only because of the enthusiasm of the practitioner. Infectious enthusiasm is most likely the key, and not all teachers have that, so maybe the gadgets help these classes. But I'm not convinced.

Griffiths was known as a great lecturer and scorned such fashions. You can hear one of his lectures here, audio only, though, without the luxury of visuals.

Boys' Results Improve Now Maths Coursework is Scrapped

When GCSEs were introduced two decades ago, one of the aims was to help girls catch up with boys in exams. The plan was a classic case of unintended consequences: the requirement for GCSEs to be graded with at least a quarter of the points from coursework has resulted in girls being awarded higher grades across the board.

Although boys and their lack of conformity in the classroom attracted the blame for their deteriorating grades by the feminised teaching profession, the truth is out: boys can doing better than girls. In Mathematics boys are now outperforming girls in all the higher grades.

So what has driven up their scores? Extra relevance of lessons? Better teacher training and school discipline structures? Lessons moved to inner city football clubs or fishing trips for malcontents?

The solution has been obvious for ten years, but has only been implemented because it has become obviouse that work completed at home was open to widespread plagiarism. It has worked for Mathematics GCSE as well as all the International Baccalaureat courses. What is holding the government up from rolling this great innovation to all subjects?

Or the QCA could allow schools to offer the IB and let market forces choose.

A Level Results will bring Clearing Heartache

Results day is nearly on us, but those unfortunate students who miss their offer grades will have fewer options than usual this year. There is more competition, and even the standard fallback, clearing, will not have many course places to offer.

For a quick assessment of the regular effects of this silliest part of the silly season on teachers check last year's post on the matter (the newspapers will just roll out the same stories anyway). This post will focus instead on the students.

This Year is Different

This year is different for anyone biting their nails waiting for Thursday's results, because of the combined effects of three government policies:
  • One is the often discussed grade inflation, which leads ever larger proportions of the school population to feel they have what it takes to succeed at university, and allows the government to claim standards are improving.
  • The second is the lack of funding to cover the extra costs to institutions of teaching the increasing numbers of undergraduates.
  • And the third is that, for the first time in fifteen years, universities will be financially penalised if they over-recruit.

Traditionally, students' applications to universities are based on the school predicted grades, which are inflated to improve the chance of an offer. It is not as risky as it sounds, since universities routinely allow students who only miss their offer by one grade to still keep their place. And everyone does it, making it fair, at least. And if they missed out, then last year 44 000 applied for course during Clearing, filling up the remaining university places.

Fewer Places

But now, with 40 000 extra applications and only 3 000 extra places, Clearing will only have around 16 000 places on offer, leaving 65 000 hopeful students without a place. And with a demographic peak reaching college in the next year or two, taking a year out and applying again next year is now looking to be a silly strategy.

One could hope that the main effect of all this is that only those students with poor grades applying to weaker institutions will suffer, but many students are unrealistic when it comes to selecting competitive courses at prestigious universities.

Rejections

Admissions officers are saying they will not allow any 'softening' of offers, so missing one A level subject by one grade will lead to a rejection. Even our local ex-teacher-training college-now-university will not soften requirements or offer places for clearing on any but the two most frivolous courses.

The next couple of weeks look likely to deliver heartache on a large scale.

NASA's LRO Spots Apollo Landing Sites

Wow, what a set of images! Come on Moon Hoax types, put this in your pipe and smoke it. The Lunar Reconnaissance Orbiter has taken some great images of the Moon's surface during its commissioning phase. Resolution will improve in the near future as the orbit is lowered to its mapping altitude and the Sun rises higher to improve the signal, but even so you can see the landers, instruments left behind and tracks in the dust.

It won't persuade the dyed-in-the-wool deniers, but will be useful in turning students away from the dark side, having been left hanging by a naïve treatment in history lessons.

Pay Offer to be Staged

I've just seen the new pay deal offered by sixth form colleges, and it wasn't what I expected. The pattern for the last few years is to match school teachers, who have been offered a 2.3% rise in September. The deal for college teachers is 1% in September rising to 2.3% in April.

This will be tricky for the unions in the current climate. With many in the private sector having pay cuts or job cuts and the government briefing the press that the public sector has done well in recent years, few teachers will have the stomach for a fight. But teacher pay has risen below inflation for a while now and has fallen 10% compared with other service sector employees in the last five years.

College funding is rising this year faster than student numbers, and there is money in the coffers to pay the award in full, so expect the unions to make plenty of noise over the next few weeks. Last year's increase was delayed until the new year due to wrangles between the staff side and the employers — looks like we'll be waiting a long time for a resolution again.

Why Are Lying Parents Socially Acceptable?

Listening to Any Questions on BBC Radio 4 this week, I was surprised by the panellists' response to a question from the audience about parents who lie on school application forms. It followed the case of Mrinal Patel, who was accused by her council of fraudulently filling in an application for an over-subscribed primary school.

The panel, comic Will Self, columnist Rod Liddle and a couple of historians, all seemed to approve of parents who are economical with the truth because any good parent will do anything for the kids. Since when has the responsibility to push your offspring further and higher trumped any objection to being a deceitful two-faced liar?

Desirable school places are a limited resource - it is a zero sum game. What one parents gains from underhand behaviour, another will lose from following the rules, and this is an objectionable and immoral position to take. Claiming to be doing it for your child is a cop out - next we'll hear the great and the good on the wireless smugly claiming that they jump the queues at Tesco and Disneyland rides for the kids.

AQA GCSE: Physics Without Physics

Last week England's largest exam board issued a Physics GCSE paper, aimed at our brightest youngsters, that required no mathematical calculations. Last year's GCSE Physics papers prompted the Qualifications and Curricculum Authority (QCA) to rule that Physics papers were not sufficiently challenging, but AQA has sunk to a new low.

The paper was the P3 Higher Tier one, so a series of conceptual deductions, calculations, simple algebra and graph interpretation would have been expected, but thousands of pupils were surprised by the disappearance from the exam of the bulk of what they had struggled to learn.

The anonymous quote about the three levels of Physics has finally become complete, officially:
There are three levels of Physics courses: Physics with calculus, Physics without calculus and Physics without Physics.
A paper made up from simplistic sequencing and qualitative statement questions is not suitable for bright or even average students, who were disappointed that they were not to be properly tested after all their rigorous preparation.

We need a new generation of scientists and engineers, but they will not be challenged or tempted by the new and 'accessable' Physics Without Physics GCSE courses on offer.

Who are these courses now aimed at? The maths-phobic or the future core of a technological society?

NUS Now Favours a Graduate Tax

The National Union of Students (NUS) has long campaigned for a university education completely funded by the state and for a return of the system of grants to cover living expenses, so the announcement of their future funding proposals comes as a bit of a shock.

Wes Streeting, the NUS president, had been under pressure to suggest an alternative to the current system of loans to pay for the fees, which start to be paid back when a graduate passes an earning threshold. He describes the proposals an 'not a simple graduate tax', and he is right - it is not simple.

Instead of a flat rate, the NUS plan has a sliding scale of tax, ranging from 0.3% to 3% depending on earnings. Wes says that this is needed to ensure that those who benefit most from their education pay back most.
There is also a system to encourage companies to pay some of the debt for employees.

I think that he has missed the meaning of 'percent', in that a single flat rate ensures that those earning more pay more. The sliding scale is a nakedly redistributive tax measure. In the NUS's words, though, it is 'progressive'.

The main motivation for the NUS funding suggestions is the pressure from the top research universities to raise the maximum fees charge from 3000 to at least 5000 pounds per year. These universities offer more of the expensive laboratory based courses than the newer institutions and are struggling to fund them. One solution is to recruit even more foreign students, who pay a much larger market rate for their studies, but local students are missing out on places.

Wes Streeting does not want an education market, but with more demand for top courses than places, something has to be done. But why should someone with two Es at A Level, studying an endemanding course at a undistinguished local college pay the same as someone studying Engineering at Cambridge?

A well educated and motivated graduate will benefit from their education, although it is their character and abilities as much as their qualifications that determines their level of career success. With the existing income tax system the Treasure already shares in the success of the best and most employable graduates. If you earn more then you pay more tax.

What is the reason for a punitive graduate tax that seeks to milk those deemed to have a privileged education, who will already be paying a higher rate of tax than others?

Coming from student political hacks, one might suggest it is just the standard class envy of the jealous young socialist. A detail from the NUS proposals that supports this guess is the limit on paying for the cost of your education if you can afford it. Wealthy families who would be happy to completely fund a course will be prevented from paying more than a small percentage, since it is these graduates who will be paying way over the odds for twenty years and funding those on lightweight courses who will never be taxed enough to cover the cost of their education.

It is nice to see the NUS abandoning one of its cherished policies, but this proposal offers more light on the proposers than on future university funding structures.

Ofsted to Control Home Educators

The government intends to extend its close control of day-to-day activities of schools to include inspecting the education provided by home educating parents.

As wth much of government policy, the pretext given is reasonable - to make sure that children not going to school are given the same protection due from the Every Child Matters agenda. Some ministers seem to suspect that home education can be a cover for child abuse or forced marriage, even there is little evidence this is the case, and the main abuse story right now is the conviction of a worker at an Ofsted inspected nursery school.

But does this fear require an Ofsted inspection, with all the political encumberances and demands? School inspections long ago changed from a supportive overview from education experts to a dogma ridden tool of control.

Parents are entitled to educate their children however they wish, without state interference. They even have the right to make a complete hash of it, as many do from my experience of trying to teach their offspring when they have outgrown their home studies.

Ofsted will pressurise and threaten parents as they do with schools, and the role will inevitable evolve to demand specific activities and curricula. Several European countries have already banned home schooling, and inspections would be the first step to declaring that the rights of children to a decent education are being violated.

Councils are already responsible for ensuring that children taken out of schools are receiving an education - the switch to using Ofsted will be the beginning of the end of the right for parents to educate their children as they see fit.
