Online Education on the Horizon

Online learning is one of my main concerns today. I'm actively working in understanding what online instructional models are the good ones for different kinds of students: university, residents at hospitals, professionals improving their knowledge, etc.
I've been looking at different (and innovative) e-libraries, e-books, e-book readers, online databases and other content containers but a single one made me completely happy. 
I'm also following in Twitter different specialists and people interested, like me, in e-learning and the future of education. It seems to me that all of us are disappointed by the lack of real innovation in this field.
Most of the key opinion leaders expressing their ideas on the net seem to end in the same concept: The Future Doesn't Fit in the Containers of the Past (Rishad Tobaccowala, CEO Denuo).
We have an inmense opportunity to innovate and try to find the correct models for e-learning.

Collecting information and learning

I had a very nice talk with one of my colleagues from Amsterdam. We were talking about how students, and other people, collect information to learn. The issue we were discussing was how medicine students build their papers and learn.

A few years ago, when I was in the Faculty of Law, I bought 4 or 5 really heavy books to read and learn. My teachers at the University told me the information needed to pass the exam was in those books. I didn’t have the internet at that time so no chance to google nor wiki.

A few weeks ago, faculty students ended their annual course and started summer holidays, after passing the final exams. I had a good opportunity to chat with a group of medicine students. I asked them about their books, how big and heavy are they? The answer was: we don’t know, we don’t use very much books now. We use the papers writen by our professors, plus some reference materials, plus google and some internet sources, like xtorrent and rapidshare.

I, then , asked about how did they organise all these informations from the different sources. They answered they all shared a usb flash memory stick and a gMail account to organise their info. They had a group and every person was responsible for creating some lessons. All lessons were then shared via Gmail or the USB stick. But the most interesting thing is that they were collecting information from different books, selecting the small pieces that were important to pass the exams, aggregating papers from the professors and related documents downloaded from differents websites.

A specific comment attracted my attention: they were trying to reduce the lessons to small pieces of information. Each of the lessons was a constructions of small pieces of information, coming from different sources, and aggregated by one of the members. All were working in the same way. The reason for that is they could retain more easily the information if they visualized each lesson with each small guide and a few contents in it.

The system they have created to learn is so different from the one I used 20 years ago…..but, at the same time, I do use the same system when browsing the web for new insigths, new ideas, new projects and new updates on me every day work. I collect small pieces of information, organize them in different “lessons” I have to read, and share them with my network.

If it’s working for them and it’s working for me, why are we still publishing heavy text books?

Color e-paper update - May 2009

An article published in Nature Photonics (read the summary of the article at http://www.nature.com/nphoton/journal/v3/n5/abs/nphoton.2009.68.html) about a week ago informs about two prototypes of color e-paper displays. It is very interesting to see that the techonology they are using comes from the past. In fact, both developments are focused on using pigments in an aqueous solution inside the pixel. Then, by manipulating the voltage on each device the liquid with the pigment draws out from the reservoir into the freee space of the pixel (in the second prototype, there are two pigments in each reservoir but with different charge properties so that the voltage controls which of them is shown in the display). 

The potential of colorized e-ink for the health sciences publishing industry is huge. It opens a vast universe of possibilities and new developments on e-books and, also, new instructional models for education, e-libraries, multiformat services and more other interesting gadgets.

Fujitsu has started to sell his first color e-reader (FLEPia) on march this year, with an 8-inch screen display and up to 260,000 colors in high-definition. Even if it's a very good start for this new market, the re-draw speed is still low and the weight (385g) and specially the price is too high if compared to the Sony e-Reader or the Kindle.

Medical images databases

I’m currently working with my team on browsing the images contained inside an ebook in a 3D environment. Tho objective is have a better navigation of the images and access the clinical cases from them. Doctors are used to see lots of images during their daily work, so it is important to navigate medical content databases the same way.

See this video I just made for better understand what we are doing:



Any comments and ideas are always welcome.

Google Books is paying

Google would pay $125 million to settle two copyright lawsuits where his book-scanning efforts were compromised by the Association of American Publishers.

The new agreement will allow Google to show a 20% of each scanned bookto the users without paying anything. The full text could also be available for a certain price. This could be a good measure but thinking on technical or scientific books I wonder if this 20% is a big big mistake.

The NYT explains that Google plans to take 37 percent of the revenue, leaving 63 percent for publishers and authors.

Sony eBook Reader PRS-505 (part 2)

After being with the Sony PRS-505 e-book reader for a couple of months and testing it with different contents (books, articles, blogs)., the final conclusions are:
  • e-Ink tech is on his first steps;
  • Color is a must have for our market (e-Ink is still B&W);
  • Lack of interactivity is a big problem;
  • Battery in the Sony reader is amazing (10 days in active mode)
  • As a simple reader is very good, but don t ask for more. Very simple solutions could be created for this reader, but this is not our interest right now (iPhone solutions are).
  • Music player integrated is awful (horrible sound quality)
  • A technology to allow reformatting texts is needed (so you are allowed to increase text size).
  • iREX should be my next Laboratory Toy.

Sony eBook Reader PRS-505 (part I)

First impression on this ebook reader when unboxing is ....."nice gadget" but let's see what's inside. And what we find there is a very good ebook reader but nothing else: no wifi connection, no color, no interactivity and little problems with PDF reading. Design could be also better....allow Apple do this for you!

It's a very good reader because it has no other ambitions and reading ebooks in the .lrf format is a nice experience. I've been reading some articles and parts of different books for the last two weeks (in very changing light ambiences) and no problems came up with this issue.

But connection or interactivity with the reader are a must-have for the next version. Sony must also allow PDF to be correctly displayed in his screen (zoom is not enough) and,
maybe, think about producing a bigger screen with touch capabilities (and eliminate lots of
useless buttons). IRex is doing quite well with its last product Iliad 2nd Edition but at a much higher price ($599 vs $299).

E-ink technology is in his first development steps so we will have to wait till improvements are available for this readers (faster changes between pages, better transitions, ink colors).

Reader is prepared for leisure but not for professionals: no medical or biology or painting books are possible without colour and other improvements.

On eBook devices


I've been recently looking at those new eBook readers coming from different companies: Amazon, iRex, Sony, Bookeen, Hanlin and others. I was asking myself which one could feed my actual needs.

All of them are based on e-ink technology and, depending on the price (from $200 to $650) they offer more functionalities. For me, two things are the most important: 1) battery life and, 2) the chance to easily upload and storage all content formats (Word, PDF, txt, html, epub, etc.).

After reading different reviews and opinions, I decided to give a try to Sony PRS-505. I will let you know my experience with it in a few weeks.
