No. These items signify the arrival of that good old time of year again. Roll up. Roll up. It is the National Student Survey.

GO ON I KNOW YOU WANT TO!

 

History of the survey 

The National Student Survey (NSS) in the UK started in 2005 and asked university students in their 3rd (mostly final) year of study series of questions relating to the experience on their chosen course (NSS, HEFCE 2005). The survey was intended to measure the ‘quality of higher education’. The questions have largely remained unchanged, and the most acclaimed and most likely to break vice chancellors out in an uneasy sweat is Q22 “overall how satisfied are you with your course”? The survey has been modified over the years and now includes additional questions for NHS based courses. The data presented is subject to a number of benchmarks and adjustments.

The survey was launched early on to a fair amount of resistance, questioning the poor style of analysis that bundles the data together and reduces the clarity of results, relying on broad and unspecific questions, and quite worrying on the back of this, that universities subsequently making important strategic decisions based on the outcomes of the survey (Jumping through hoops on a white elephant, 2008).

 

Is experience becoming more important than education?

The survey, despite these early robust discussions, has not gone away, and quite to the contrary. Whilst the survey itself remains largely unchanged, the resourcing and time investment by institutions to ensure an effective process for collecting responses is now a significant activity in every academic calendar. It is part of the ‘business’ of Higher Education and feeds the growing appetite of the sector for key performance indicators, data, league tables, frameworks, benchmarks, as we all set to the business of ‘measuring’ what education is. Couple this volume of work with poor data management systems, the increasing need to deliver and duplicate this data in a variety of forms to other places, the administration and teaching teams within universities are not surprisingly under huge pressures and experience unhealthily long working hours (UCU 2014 Survey). As with other areas of the public sector, I’m sure we’d much rather spend our time educating young people, and do the job we were initially intended to do?

But what will happen next – some positive action or collapse? I get a sense of a rise in scepticism across the sector as reported in a previous blog post (Guinea pigs in a maelstrom, 2014), where at the Society of Research into Higher Education annual conference, Bob Burgess and Jurgen Enders questioned with regards to league tables:

Aren’t there bigger problems to solve?

 

Like an academic arms race.

 

Add the shoe sizes of VC’s into league tables! Would be just as accurate.

I am optimistic we are on the verge of one brave institutional leader saying enough is enough.

 

So does it provide a useful view of the quality of education? What do people think?

I don’t doubt at all that prospective students and their families should be better informed about the performance of their institution to which they might be making a considerable and hefty commitment to. However are league tables the best way of doing it? I would question whether people read or indeed understand the increasing numbers of them. Having spent 12 years doing open days at three different universities I can honestly say I cannot recall it being a subject of conversation once. University choice is about gut feel of a place, it is about coming to an open day and meeting great existing students, academic and technical staff. If anyone makes a decision based on the position of a university on a table alone, they must be pretty mad.

But what do people really think, and going back to the cuddly toy, are incentives wrong? Incentives are an established means in market research for improving response rates and quality of responses to questionnaires. You might think they naturally bias responses toward being more favourable? Research shows this is not always the case, but the optimum incentive point must be found, otherwise the opposite can happen, and respondents start to get pretty naffed-off. One way to minimise any bias would be to get students to complete the survey independently of their univeristy – they complete the ‘Destination of Leavers from Higher Education’ – graduate employment – survey 6 months after leaving, so why not the NSS? Why not manage the survey centrally via the student union to relieve the burden on the teaching teams?

So what do students think of the survey? We don’t really know to be sure, but one media article about it, attracted a colourful range of comments:

Doing ourselves a favour by reviewing the university positively

 

We were pressed by tutors to answer certain questions in a particular way

 

Taxpayers deserve more open, fuller accountability by this sector because of the huge amounts now spent and the financial burden put on our young people.

 

Still, I remember my uni days fondly and would encourage anyone to seek out a uni experience and screw the untrustworthy rankings.

 

You can read the conversation for yourself. (BBC, Universities face survey warning, 2008).

 

What about the meaning of the data?

So what do we really know about the meaning of the data? Do we every really sit and question it? All the data is openly retrievable with data sets going back to 2005 on the HEFCE website (http://www.hefce.ac.uk/whatwedo/lt/publicinfo/nss/data/2008/ ). This is the approach I took to looking at it in this first instance.

1) I downloaded all the Higher Education year datasets to an Excel spreadsheet.
2) I looked at the ‘registered’ data as opposed to the ‘taught’ data – data being responded to the institution at which the student was registered rather than where the majority of teaching may have been.
3) I manually corrected the variation in university names over the years, and included the latest name for those institutions that had been renamed.
4) I sorted the data by institution to allow for comparisons across each year.

Work by Paula Surridge (http://www.bristol.ac.uk/esu/ug/nss/research.html ) informed the use of benchmarking, adjusting for subject, ethnicity, age, mode of study, gender and disability. It does not adjust for socio-economic group which on the surface is rather surprising. In 2008, the benchmarking changed, so comparing to data prior to that is not terribly useful.

 

NSS Q22 % Satisfaction
Figure 1. Overall % Satisfaction looked at across 30 HEIs from 2005 to 2013 to illustrate the change in benchmarking in 2008 and subsequent compaction of the data.

 

HOW SATISFIED ARE STUDENTS ACROSS THE UNIVERSITY SECTOR?

NSS % Satisfaction ALL HEI
Figure 2. Overall % satisfaction, HEIs in England, 2010-2014. (Arranged alphabetically)

 

When I first plotted this out by arranging the HEIs in England alphabetically, I thought it looked pretty and rather interesting. My partner thought it looked like the German world cup football strip. My statistician, who I gave the data blinded, observed “clearly some pattern and cyclical event going on”. I enlisted the help of a second statistician to analyse the data.

Performing an ANCOVA to compare year on year differences, there were significant differences between each year group with the exception of 2013 to 2014. Each institution was incrementally better year upon year until 2013 when there was another benchmark change.

Conclusion? The data suggests students are more satisfied year on year with the HEIs in England. Or, are the processes to gather the data are improving year on year?

 

HOW DO THE DIFFERENT UNIVERSITY GROUPINGS COMPARE?

Data was sorted according to Russell Group, Alliance University or other.

NSS_Trend
Figure 3. % Overall satisfaction by group and extrapolation of data. (RG Russell Group, UA Universities Alliance, Oth Other)

 

By sorting universities in England by their commonly referred to groupings, and extrapolating the dataset,  the Russell Group clearly achieve higher satisfaction rates compared to Alliance Universities and all others. The data does however show their rates of satisfaction slowing down. Should the benchmarking remain unchanged, by 2018, the UA and other will match the performance of the Russell Group. By 2023 the ‘others’ nose past the winning post being the first to reach 100%.

Improvement in satisfaction or processes?

It is not clear what the nature of these observations really are, and with all my discussions on the data, there are some interesting hypotheses. I hope this article prompts some serious data analyst to interrogate the data sets more fully. I have done the same analysis on other questions – and there are interesting differences with those also.

But do we see this elsewhere? In the 2014 REF the sector seemed to incrementally improve with suggestions that the evaluation is flawed (The Guardian, REF 2014), and whilst we cannot doubt the amazing and outstanding work that does go on in UK universities, we could say that this was also due to also improvements in the system.

One thought that has come up a few times is that we are dealing with a system that is corrupt – and by human nature if you set us targets and measure our performance, we will work to comply with those targets. We all know that is exactly what happens – how do we spend much of our academic time?

Donald Campbell was an economist who observed this in his writings in 1976:

The more any quantitative social indicator (or even some qualitative indicator) is used for social decision-making, the more subject it will be to corruption pressures and the more apt it will be to distort and corrupt the social processes it is intended to monitor.

Charles Goodhart an economist made similar observations in 1975, now known as ‘Goodhart’s Law’:

When a measure becomes a target, it ceases to be a good measure.

 

Where do we go from here?

I do think the HE sector needs to take a good look at itself and understand fully the series of measures and targets to which our performances are increasingly evaluated (research, students satisfaction, teaching performance). If we do persist in having monitoring systems, they have to be run effectively. We are detracting academic staff from doing their jobs, and the pressure on teams do get good results, as we’ve see with the REF can develop a sinister side (The Guardian, REF 2014). Higher education is not a theme park delivering a jolly experience. It should be nurturing and at times challenging one to enable learners to develop and achieve meaningful goals, and I would therefore at times be quite happy if my students at times were left a little unsatisfied because I had chosen to stretch their thinking and their approaches.

But meanwhile.

“Good game. Good game”.

 

Outside with eyes looking in.

Eyes

I’ve not blogged for a while. I think my feelings are cyclical and run in long waves fuelled by intense spells of work activity that either lead to phases of excitement when I actually achieve something, or depression when I do not. I’ve always had very acute ‘gut instincts’, and this might be because  I am a gut physiologist and understand the beauty and power of the intestinal enteric nervous system being far more sophisticated than that knot of fibres in our heads that we call our brains. (Our ‘little brains’ are far more interesting than that great big lump we carry around on our shoulders). Animals are totally powered by their instincts and their sensory systems, and if anyone has ever thrown a ball for a springer spaniel, they will watch the animal run and find the toy not by using their eyes at all, but entirely by the power of smell. We humans are useless at that.

The enteric nervous system is entirely ill-understood, and that is mainly because it is so well hidden. People don’t really understand the full structure of it, or how it works. What we do know is the gut is one of the few parts of the body that completely has its own control unit and can fully work when severed from the brain. There are no electrophysiological, imaging or scanning techniques that can look at gut electrical waves / functions or activities as there is in the brain. Science always studies the bits of the body it can most easily test or retrieve, and certainly will always study those that attract the funding. Unfortunately the gut, apart from stomach ulcers, has never been very trendy. And very, very unfortunately, this means that probably the most common ailments to mankind, and certainly still one of the biggest killers of children as it was when I wrote my PhD thesis 20 years ago, that is diarrhoeal disease, still go reasonably unexplored.

So yes, it worries me when I have a hugely positive day surrounded by national teaching fellows in the afternoon who personify dedication to young people, passion and creativity in learning and teaching, and yet I arrive home totally depressed. As usual, my brain is several hours behind what my gut has already felt. Come on. Hurry up and decipher. This is wrong. But what?

What IS wrong?

I work with amazing people – my third university now in around ten years. I met more amazing people today. I think my realisation today is that in universities, anyone achieving the cool stuff, the innovative stuff, they do it in their own time? It has culturally acceptable for many years to dedicate time to research interests outside of work, ‘oh, I don’t do that at work’, ‘oh, I’m a kitchen table researcher’. I think what struck me today more than ever, is that academics are now dedicating time to their TEACHING OUTSIDE OF WORK!

TEACHING OUTSIDE OF WORK. Not just in terms of their time commitment and their willingness to give up their spare time, but in terms of the technology they are using and the support they are getting from global communities. OK I know I still feel like a newbie to the sector because I spent a fair chunk of time in industry. I always feel like I don’t entirely belong, and I am standing on the outside looking in, but WHAAAT? WHAAAAAT?

I am not just mildly annoyed by colleagues for years saying, ‘oh we daren’t involve the XXXX department in this’, or ‘oh we are doing it anyway’. I am getting absolutely sick to the stomach about it. Do parents and prospective students fully understand the fact that universities spend vast amounts of money on the administration and infrastructure to support the organisation, but not on what goes on in terms of delivering the education within it?

Crimson Permanent Assurance

 

The Crimson Corporate University of Snerterton-Upon-Snerterton

I can’t help but be reminded of Monty Python’s Crimson Permanent Assurance – ‘people are not wearing enough hats’ – and a dead organisation that started to regain its own mind and set sail in a different direction. In my experience,  if not careful, a poorly run organisation becomes an organism that takes on its own slime-like life form – the processes and systems become its lifeline, nourished by the bureaucracy and energised by the acronym-filled emails. (Yes I really did have an email yesterday containing 19 of the buggers). The organisation starts to evolve no purpose other than to support itself. I think this for me, with the easy eyes of an outsider new to academia, is what I have observed over the last decade. Academics and administrative teams become increasingly busy with the ‘business’ of making the organisation work. Staff are now completely bamboozled with targets, surveys and key performance indicators. But I’m not sure all is lost, because the amazing thing is that when ‘enrolment’ week began last week, the buzz of excitement within the university was immense. Staff were absolutely thrilled to be meeting new students once more. Yes, well yes, because that is what we WANT an SHOULD be doing.

The future?

Futurelols

 

 

 

 

 

 

 

 

You can never find a futurologist when you need one, although the last time I met a futurologist he had entirely read the first paragraph on Wikipedia on the subject. Well, my crystal ball tells me that I can now see the sector fragmenting. I see the private sector jumping ahead of the game providing online content and accrediting learning. I see a university elitist group separating off from the main who attract the research funding and the high-end applicants. I see polytechnics returning to provide ‘real-life’ training for those wanting a vocational option.

National Student Survey Q22

UK National Student Survey Data Question 22 – Student Satisfaction. (HEFCE, benchmarked, registered data, available: http://www.hefce.ac.uk/whatwedo/lt/publicinfo/nss/data/2010/ – onward).

Many people are therefore going to be very busy. But I see everyone else contributing to OPEN ONLINE LEARNING for the purpose of simply imparting their passion about various subjects to students, and for free.

So those are my gut instincts and my brain’s interpretation of the day. Although reading this now, I don’t think this IS the future. THIS IS REALLY HAPPENING NOW.

How to flash safely?

Twitter discussion

The other day, the topic of gifs and photosensitive epilepsy came up on DS106 Twitter, so I thought I’d find out more. I went straight to the medical journals and asked a friend of mine who works at Jisc TechDis.

Types of light sensitivity?

There are a range of ill-defined sensitivities to light, from facial twitching in response to bright light, actual induced changes in brain electrical activity, and changes dramatic enough to induce a seizure. The latter is referred to as photosensitive epilepsy.

What objects or aspects of light can evoke a seizure?

Many of the medical papers report the most common stimulus is a FLASHING LIGHT, and can also be PATTERNS OF LINES, GRATINGS or CHECKERBOARDS. I think we all recognise sometimes we can watch stripes or squares on the TV or PC screen that make our eyes feel funny.

How many people does this affect?

The figures are a little unclear because the data relies on individual’s own reporting, and tests actually done in the lab measuring brain activity (electroencephalograms EEGs) are usually on selected individuals and not necessarily those at risk so are likely to be lower. Nethertheless, the figures range from 5 to 9 % of the population. SO IT IS STILL A RISK FOR A NUMBER OF INDIVIDUALS. (Fisher 2005). Studies suggest it is more common in young people than in adults.

Notable cases?

There have been cases of TV programmes and video games inducing seizures. Wilkins and colleagues (2005) described a case relating to a TV advertisement (Golden Wonder Pot Noodles) where seizures were reported in three viewers in the UK. In Japan in 1997 a children’s program “Pokemon” reportedly led to 685 admissions to hospital, with 560 identified as epilepsy. The cartoon displayed alternating red and blue backgrounds. What was startling was most of these people had never had an episode before. I’m not sure of the follow-up, meaning, whether this was just a one off event or actually primed the people into being sensitive, I do not know.

So what colours and patterns are thought to be worst?

Wilkins 2005 paper led to guidelines being introduced in the UK and Japan, and now also internationally. Although they are devised for TV and not PC screens where proximity, resolution and environmental conditions may be different, they are a useful guide for our understanding.

1. Frequency. Flashes with frequency >3 Hz are prohibited.

2. Opposing changes in luminance. Flashes ≥20 cd/m2 are prohibited.

3. Area of flashes. Flashes greater in area than one fourth of the screen are prohibited.

4. Color. Flicker from saturated red light is prohibited.

Where:

Frequency – in Hertz (Hz), the number of cycles of the pattern per second. Fisher (2005) reported that the majority of people in their study responded at a peak of 12–30 flashes per second, but Wilkins’s 2005 paper reported this lower at 3Hz or above.

Luminance – relates to the contrast between light and dark. The bigger the contrast, the bigger the risk.

Areas – stationary patterns seem worse than ones that move slowly. Stripes, gratings and  patterns are implicated more than spots for example. The paper explains this relates to area covering the screen. On a PC we can assume the pattern might occupy the entire screen.

Colour – red is thought to be more provoking, although the effect of colour is not really well known. The importance of luminosity and contrast is much greater as a consideration.

So they recommend as a correction for you to look at the screen and ask these questions:

Are there more than five stripes?
If so, do they last longer than 0.5 s?
If so, does the brightness exceed the stated limit? If so, categorize the motion of the pattern
Are the guidelines contravened?
If so, reduce brightness.

 

———————–4life——————————————————————–

So what can we do?

  • TV broadcasts are now monitored, but computers and video games are a bigger risk.
  • People with known epilepsy will safeguard themselves using screen protectors and maybe coloured glasses, but many people just won’t know.
  • Whilst the guidelines are written for TV, the effect of digital screens is less well known.

How to practice safe gifs?

Well not just our beloved animated gifs, but video and animations. I would use the criteria above as a guide – avoid flashing geometric patterns of contrasting colours.

But as my friend at TechDis commented:

Just don’t do it. Its not good for accessibility or usability.

As reported in a specialist workshop in 2004, flashing images on websites and roll-over-images are not good for usability. (NGfL Accessibility workshop 2004). I guess if we are making “art” we might want to think about it a bit more carefully.

And some additional notes on accessibility from Terry at TechDis regarding visual formats:

The accessibility of an image depends on technical factors (colourless, contrast, sharpness) as well as pedagogical factors (how effectively it is labelled, how well it is described, how it is integrated into a text / audio narrative).

For moving images, video and gifs:

However visual formats can create barriers to people with poor sight and they tend to be far less searchable and navigable than text.

 

So, we should certainly think about the art we are creating, and maybe we should be more careful about accessible alternatives to go alongside it?

 

Or maybe we should consider having a clear warning if we are unsure?
