Reading on screen and on paper

September 1st, 2019 by Graham Attwell

Do you read books and papers on screen or do you prefer paper. I am conflicted. I used to have an old Kindle but gave it up because I am no fan of Amazon. And I used to read books on firstly an ipad and latterly an Tesco Huddle tablet – both now sadly deceased.

Like many (at least if the sales figures are to be believed) I have returned to reading books on paper, although I read a lot of papers and such like on my computer, only occasionally being bothered to print them out. But is preferring to physical books a cultural feel good factor or does it really make a difference to comprehension and learning?

An article in the Hechinger Report reports on research by Virginia Clinton, an Assistant Professor at the University of North Dakota who “compiled results from 33 high-quality studies that tested students’ comprehension after they were randomly assigned to read on a screen or on paper and found that her students might be right.”

The studies showed that students of all ages, from elementary school to college, tend to absorb more when they’re reading on paper than on screens, particularly when it comes to nonfiction material.

However the benefit was small – a little more than  a fifth of a standard deviation and there is an important caveat in that the studies that Clinton included in her analysis didn’t allow students to use the add on tools that digital texts can potentially offer.

My feeling is that this is a case of horses for courses. Work undertaken by Pontydysgu suggested that ebooks had an important motivational aspect for slow to learn readers in primary school. Not only could they look up the meaning fo different words but when they had read for a certain amount of time they were allowed to listen to the rest of teh story on the audio transcription. And there is little doubt that e-books offer a cost effective way of providing access to books for learners.

But it would be nice to see some further well designed research in this area.

How to live stream events

September 5th, 2010 by Graham Attwell

I talked in previous posts about our work with the European Conference on Educational Research to ‘amplify’ the conference, recently held in Vienna. This involved setting up various social media channels including a Twitter stream and a iTunesU page, producing a series of video interviews with conveners of the different networks which organise ECER and b9radcasting three live radio shows from the conference.

We also undertook to stream four keynote speeches, run in two parallel sessions as well as the opening. Easy, I thought. Like many of you I have live streamed from different events, pointing a camera or even a MacBook at the speaker and linking in to  uStream or Justin.tv or one of the other social video platforms. It turned out not to be so simple.

We were working with a community not generally used to social media. And quite simply, the idea of pointing them to a platform advertising poker, acne treatments didn’t seem a good idea. Plus we had an issue with the reliability and quality of the free services. Livestream looked a better idea especially though their premium accounts. This allows you to have your own channel and remove the adverts.but a single channel on Livestream costs 350 dollars a month, with twelve months billing in advance. And we needed two channels. Back to the drawing board. We discovered that Ustream has set up another service called Watershed and indeed for a time were tempted by this. Watershed offers per view payments, but the prices are relatively high. And the terms and conditions of service for the monthly or annual contracts was impenetrable. No problem, we thought, we will ring them and clarify the conditions. Then we discovered there was no telephone number on their site. All you cold do was ask questions on a bulletin board, largely filled with complaints about the service and the total lack of technical support.

OK – so that didn’t seem such a good idea. Last resort – ask a friend. I twittered out for anyone with ideas of a service we could use. And somewhat to my surprise, no-one could come up with a solution, other than the services we had already looked at.

Back to searching on the Internet. Of course there are many companies offering professional streaming services but they all seem geared towards corporate or media organisations, not towards education or for relatively low numbers of live viewers.

I finally stumbled on a web site from a Canadian company called NetroMedia. Their prices were not clear but they said that for one off events you could fill in a query form. So I did, not with any great hope. To my surprise about half an hour later, I had an email reply asking for more details about the event I wished to stream. And to my even greater surprise, some forty minutes after returning this a person rang me. Yes, a real live person!!!

She calculated how much bandwidth we would need and offered us a service for 100 Canadian dollars, plus 20 dollars for unlimited technical support. (Note that if you buy into this or a similar service, it is important to buy sufficient bandwidth in advance, extra bandwidth per view is relatively expensive). Woo, away we go. Even better some twenty minutes after paying them, Darren, the technical support man rung us. This was very helpful, because although the set up is relatively simple, we required two video streams going out simultaneously, and that required a little fiddling.

NetroMedia do not offer a portal for streams. Instead they provide a streaming service and you embed a Flash video player in your own web site. This suited us just fine. The up stream was encoded through the free Adobe Flash Media Encoder, which worked well on both a PC and a Mac. The only thing I would like is to have more direction control over what we were streaming – e.g to be able to switch between a feed from the data projector and the video but I am sure we can work out how to do that. I am very happy with the quality of the streaming (you can view the recordings by clicking on read more on each of the channels on the ECER video streaming web page) although we were helped in this regard by the kind loan from Helsinki University of two very good video cameras.

Of course, if you are working in a University or large organisation, you may be able to run your own streaming server.But such an investment is beyond Pontydysgu, or I guess many small organisations. Yet video streaming is going to be an important part of Amplifying future events. And we need a reliable and reasonable quality of service.  I would certainly go to Netromedia again. But I also wonder if there is some way we could collectively organise resources for streaming in the educational technology community to both share know-how and expertise and infrastructure.

    Racial bias in algorithms

    From the UK Open Data Institute’s Week in Data newsletter

    This week, Twitter apologised for racial bias within its image-cropping algorithm. The feature is designed to automatically crop images to highlight focal points – including faces. But, Twitter users discovered that, in practice, white faces were focused on, and black faces were cropped out. And, Twitter isn’t the only platform struggling with its algorithm – YouTube has also announced plans to bring back higher levels of human moderation for removing content, after its AI-centred approach resulted in over-censorship, with videos being removed at far higher rates than with human moderators.

    Gap between rich and poor university students widest for 12 years

    Via The Canary.

    The gap between poor students and their more affluent peers attending university has widened to its largest point for 12 years, according to data published by the Department for Education (DfE).

    Better-off pupils are significantly more likely to go to university than their more disadvantaged peers. And the gap between the two groups – 18.8 percentage points – is the widest it’s been since 2006/07.

    The latest statistics show that 26.3% of pupils eligible for FSMs went on to university in 2018/19, compared with 45.1% of those who did not receive free meals. Only 12.7% of white British males who were eligible for FSMs went to university by the age of 19. The progression rate has fallen slightly for the first time since 2011/12, according to the DfE analysis.

    Quality Training

    From Raconteur. A recent report by global learning consultancy Kineo examined the learning intentions of 8,000 employees across 13 different industries. It found a huge gap between the quality of training offered and the needs of employees. Of those surveyed, 85 per cent said they , with only 16 per cent of employees finding the learning programmes offered by their employers effective.

    News from 1994

    This is from a Tweet. In 1994 Stephen Heppell wrote in something called SCET” “Teachers are fundamental to this. They are professionals of considerable calibre. They are skilled at observing their students’ capability and progressing it. They are creative and imaginative but the curriculum must give them space and opportunity to explore the new potential for learning that technology offers.” Nothing changes!
