Exams are getting easier every year

Saturday, August 28th, 2010

Another year of record exam results is upon us, and of course, they’ve got easier again.

While this is often refuted by the industry, here are two reasons why exams arguably genuinely are getting easier every year.

1. Teaching standards get better and the exams do not get proportionally harder as a result.

The argument against this is that just because teaching standards are getting better doesn’t mean that the exams should get harder as well. After all, if you can teach a child more stuff in a shorter period of time, that actually means they do actually know more and thus deserve a higher grade than the generation before.

However, to add to this discussion, there isn’t a great deal of evidence that younger generations are actually significantly smarter than previous ones. Teaching standards are getting better, but not necessarily at teaching children useful information, rather they are getting better at teaching kids to do well in exams.

If there was huge leaps of improvement in teaching techniques to make children smarter, surely we would all expect to be significantly smarter than our parents and I don’t think this is the case.

2. The exam board make conscious decision to award higher grades each year.

It’s all very well saying more children reached A grade standard this year, every year, but this is actually a long way from the way that universities work.

At degree level, everyone sits the same paper, they are all marked and then they work out how easy or how hard the paper was and move the grade boundaries according – so if everyone got really high marks they will up the grade boundaries to reduce the amount of people that did well and if everyone did really badly they reduce the grade boundaries to increase the amount of people that passed.

This prevents one year who get a really hard paper being unfairly punished against a year later which may get a much easier paper. This is a system which has been functioning in universities for a long time and seems to work very well.

Arguably this means that fifty years down the line you end up with people who should be achieving far higher grades than people do now, getting the same grades but who really cares? Exam grades are really about employers and universities being able to differentiate between people and once you have a degree or a job nobody really gives a crap about your GCSEs and A-Levels so what does it even matter if that is the case?

Phobiology

Sunday, July 18th, 2010

I was thinking about the selective attention videos Jonni was showing me earlier and that lead me on to thinking about some videos I saw many years ago that made me jump.

Such videos to something along similar lines of this: they present to you two identical pictures and ask you to “spot the difference.” Of course there isn’t any and as time goes on your eyes move closer and a closer to the screen as your concentration increases to try and spot the differences you are told are there to be spotted.

Suddenly a ghostly image appears and a scream comes hurtling through your speakers and the majority of people will jump. There is a crude example of such a video here.

This got me thinking, it’s actually quite easy to scare someone. How many times have you walked up behind someone concentrating on a computer screen for them to suddenly realise you are there, jump and claim you “scared the life out of them.” Probably many times.

And yet, horror films continually fail to scare us on a regular basis. When was the last time you watched a horror film that was actually scary? I found Silent Hill had a good attempt but that was a few years ago now and most people found that rather tame. Of course it varies from person to person but most people I talk to, at least among my male friends, claim they haven’t seen a scary movie in a long time. Of course they could just be embarrassed to admit they were scared but for the moment lets take them at their word and assume all recent horror films haven’t scared them.

Surely we must be able to put some science behind this?

Take roller coasters for example. There is a lot of research and engineering that goes into making roller coasters and exhilarating experience. The problem is now that they simply can’t make them go any faster, drop any steeper or throw people around any more than they already do without injuring people.

So, as a friend was explaining to me, they’re now working on techniques to make people feel disoriented. The current avenue of research is to attempt to recreate the feeling we all had when we were children and went rolling down hills (I say children, I would imagine in Michelle’s case, it was last week as I presume it still works ;) ) and that sensation of tumbling over and over. They can do this already but not without people throwing up everywhere, so the research continues.

I would have thought, in the same way, we could apply new techniques to horror movies rather than just adding even more blood, gore and guts to each film. Maybe they already are of course, but I think so far, the general consensus is that it isn’t working.

Football gets everywhere

Monday, July 12th, 2010

The World Cup manages to get everywhere – and arguably so it should – though it was surprising to find that it even made it as far as the Humanist Community of Leeds with Gijsbert dressing up in all orange to support his home country, The Netherlands.

Inspiring ideas

Saturday, June 12th, 2010

One of the aims I always wanted for the foundation, was that we would be an organisation that got out there and did stuff. Not just talked about it, or planned it, but actually got out there and got something going. I’m pleased to say that our work seems to be inspiring other organisations to do the same.

Having just read the latest copy of the BHA News which arrived through my door a few days ago, I noticed they have now formally launched their equivalent to our One Life course, Exploring Humanism, complete with a overtly stock image as I am a sucker for using on our projects too.

Just a week after our Enquiry 2010 conference took place, the BHA have announced the return of their annual residential weekend conference and following our public announcement of the Humanist Chaplaincy Network during the weekend, they have also announced they will soon be launching the Humanist Chaplaincy Working Group too.

I’m really proud that despite only being a year old, the work of the foundation is already inspiring many others in the non-religious community to get out there and make a difference. Long may it continue!

Pleasant surprises

Saturday, May 29th, 2010

In a sea of everything going wrong at the moment, I got some very pleasant news on Thursday morning when I found out my car passed it’s MOT! I was expecting it to fail to be honest because of the right up it got on it’s last service but apparently everything is in working order enough for it to be road legal so let the good times roll.

General election

Sunday, May 16th, 2010

I have to say, the general election was rubbish.

I had to queue for 40 minutes to vote. I actually really regret that now, as much as you should participate in democracy, no metric when you think about it would actually have been worth a whole 40 minutes of my precious time given that Hilary Benn was always going to win the seat for Labour once again.

But yes, that footage of everyone queuing outside Trinity Church in Leeds, that was me. Well, that footage wasn’t me, I did it earlier in the day, but much like everyone else I went at first (around 6pm) and saw how long the queue was so I thought I would come back two hours later when the queue had died down only to find it had gotten even longer.

The error in my logic was thinking that most people didn’t live in the city centre and so would be voting at around 6pm as they got the bus home from work, passing through town of course. It was only later I realised how silly this was – obviously if they were bussing it home to somewhere else, they would be in a different constituency.

In my defense though, having looked at the queue I believe most people would have thought the same thing – it was full of shabby looking poor lower-working class people so my instant reaction was that they obviously couldn’t afford to live in the city centre and must just be voting here and then going back to whichever slum they live in. I still think this is probably the case and just the Leeds Central constituency stretches father than I realise.

And then after all that, I stay up all night to watch the election and we don’t even get a real result.

I think the biggest argument for our current electoral system is that if we switched to proportional representation, most election nights would be such a massive anti-climax. I stayed up until about 5:30 because all the interesting results – the Leeds ones for me obviously, Brighton Pier, Barking, Buckingham and Oxford West took absolutely ages to declare.

Indeed the only one I managed to catch while in some state of consciousness was when Oxford West was announced, only to find out that very disappointing Dr Evan Harris had lost his seat. And thus was the death of science and evidence based policy in the House of Commons.

What a massive disappointment all round really.

Going back to basics

Sunday, May 16th, 2010

Back when I originally moved over from Nerd Federation to my own personal blog, one of the major reasons I quoted from getting a “fresh start” with the move to WordPress and a new policy of direct, to the point blogs, was that I just didn’t write much on Nerd Federation anymore because I had got myself into a pattern where I felt I needed to write a lot, and so didn’t, and so never blogged.

Of late I feel I have fallen into this trap once again. I’ve simply been too busy of late to write long, photographed blog posts and so I just haven’t been blogging. But there is a lot going on I would like to talk about and share and so it seems an appropriate time to try and start fresh with new, shorter blog posts – which also has the advantage that anyone reading my blog doesn’t have endlessly long posts to slog their way through.

I really have been busy recently – the last time I can remember having an evening at home relaxing, rather than working, was somewhere near the start of April. Still, everyone thinks they are busy, indeed every year I seem to look back and think “I thought I was so busy a year ago – but it’s nothing compared to now.” Makes me wonder how we will all feel next year when if the model holds, we’ll be even busier than we are now lol.

Re-examining Atkins

Tuesday, March 9th, 2010

One of the guys in my office has been doing the Atkins diet for a while now. This caused me to take a look at the research carried out on low-carbohydrate diets to see if there was any basis for the misery he is putting himself through.

Most people including myself just kind of wrote off the diet because the pseudo-scientific explanation behind it didn’t make much sense. However in 2004 the flagship BBC science documentary Horizon broadcast an episode showing it probably does work for reasons differing from those that Dr. Atkins actually claimed.

In fact, looking into the evidence for low-carbohydrate diets, while there is a huge mixed bag of results, the overall consensus seems to be that while more research is needed in the area, such diets are generally safe and are effective in weight loss.

Of course this isn’t to say that everyone should jump on Atkins. Diets are no replacement for basic healthy eating and well all know this. We’re all well aware the way to be healthy is to eat a balanced diet, treat yourself occasionally, hit all the major food groups and avoid eating prepared meals, fast food or generally anything that doesn’t require you to put some effort in preparing yourself, as much as possible. However, if you are going to diet, Atkins at least isn’t any worse than any other diet.

In the eyes of the innocent

Sunday, March 7th, 2010

I love Richard Dawkins. But sometimes I think he is a bit too nieve. Take for example the recent goings on on the RD.net Forum. A few weeks ago they announced that the forum was going to be replaced by a new system. A system which was “similar to a forum” but had some differences, most notably threads would be tagged instead of categorised and that all threads would be moderated.

They announced they would be leaving the forum operational for 30 days and then replacing it with the new system. However two days later the forum was locked down with a message from Richard saying the following…

Imagine that you, as a greatly liked and respected person, found yourself overnight subjected to personal vilification on an unprecedented scale, from anonymous commenters on a website. Suppose you found yourself described as an “utter twat” a “suppurating rectum. A suppurating rat’s rectum. A suppurating rat’s rectum inside a dead skunk that’s been shoved up a week-old dead rhino’s twat.” Or suppose that somebody on the same website expressed a “sudden urge to ram a fistful of nails” down your throat. Also to “trip you up and kick you in the guts.” And imagine seeing your face described, again by an anonymous poster, as “a slack jawed turd in the mouth mug if ever I saw one.”

What do you have to do to earn vitriol like that? Eat a baby? Gas a trainload of harmless and defenceless people? Rape an altar boy? Tip an old lady out of her wheel chair and kick her in the teeth before running off with her handbag?

None of the above. What you have to do is write a letter like this…

You can find the entire thread here. Needless the say the letter that was written wasn’t in any way offensive – it was very pleasant and upbeat. But never the less it attracted widespread abuse from forum users. Here is why I think the reaction was nieve though…

Firstly, Richard’s first assumption is wrong. “What do you have to do to earn vitriol like that?” The answer actually is write a letter. Post a YouTube video. Visit /b. Basically anything on the internet attracts that kind of abuse, it saddens me that, that is the case but unfortunately that is how the internet is. Every time I post a YouTube video someone makes a stupid, inane and abusive comment, that’s life unfortunately.

Secondly I think it’s also a mistake to assume these comments are coming from people sympathetic to your cause. I suspect they didn’t. One possibility is they came from religious people just looking for any way to get to him but I suspect such comments actually came from general internet trolls who don’t really care about science, reason, debate or maybe even Dawkins, generally get off on the idea of annoying religious and non-religious people and just wanted to cause trouble. Basically imagine an even younger, more irriguous version of my friend Will.

I also suspect that it may be a nieve thought to think you can control and moderate the internet. I suspect a lot of the user base will be lost because people don’t like moderation because of the pressure it puts you under. However I could be wrong about this, only time will tell. At very least though you can see why this would annoy people.

When life gets tough you find out who your friends are

Thursday, February 25th, 2010

For those who don’t know I was stuck down ill on Tuesday night. I managed to claw my way back into work today but that was probably a mistake given how I am feeling now.

In any case last night didn’t help. Having not really slept properly since Monday night I finally managed to drift off in the early-ish hours of this morning having gone to bed about 11pm. And by gone to bed I mean tried to sleep, I didn’t actually get out of bed at any point yesterday save to make myself some food.

Anyway, I had finally dozed off when I was awoken at the sound of my UPS beeping like crazy at 3:30am. The power had gone out.

Needing to sort out my computers I reached for my torch, carefully positioned on my bed side table for such occasions. Of course being ill and knowing I needed plenty of fluids I had carefully positioned a glass of orange juice next to my bed.

Of course, it went flying spilling it’s contents over the top of my bedside table as well as the wires and printer sitting below it. And of course I couldn’t see to mop it up because we didn’t have any power so none of the lights were working.

So here I am, cleaning up the mistakes of last night despite the fact I’m physically exhausted and despite the fact I still have loads more to do tonight before I can sleep.

But at least through it all, I know I have you. All of you. Everyone of you, each of you different and each of you amazing in your own special way. I honestly don’t know what I would do without you. Never leave me, Dairy Milk.
