[IAEP] Apple Eases Restrictions On iPhone Developers

[Caryl Bigenho]

Hi...
Don't know how this happened to get sent again... sorry!  But since I'm here I would like to remind everyone that there is far more to education than computers and technology. Sometimes folks get so wrapped up in their own ideas that they fail to see the "big picture".  
I don't think I will say anything else in this thread.  It doesn't seem to serve any purpose, since I'm just a lowly educator speaking.  'Nuff said!
Enjoy the rest of the weekend!

Alas, 


This is just one more example of the growing digital divide... between the "techie" community  and the educational community.


It is time the techies give some respect to educational research and research in neuropsychology and learning theory.**  The guidelines for research in these areas are very rigorous, and experimental design goes through careful review before, during, and after it takes place.  Results are reported in scholarly journals and professional meetings.


If the "techies" know so much more than the educators and neuroscientists, why don't they share their knowledge in a scholarly fashion and subject it to the same rigorous scrutiny?


Sorry for the rant, but it sometimes seems we aren't speaking the same language. Yet I know we all want the best for our real clients... the students.

** The same thing could be said about the government officials who still believe that standardized testing is a measure of learning.

Steve didn't forget anything -- he caused the iPad to be redeveloped and put out as a product (that was what I was referring to).

It's not just small type -- it's small page size, not enough pixels for great antialiasing, and also trade-offs between visual angles due to the conflict of sampling between two discrete mechanisms (display and retina).

And visual angle is also very important younger ages, and for drag and drop construction, visible resources, etc. For example, the excellent Scratch interface is not nearly as effective on the XO despite the large number of pixels.

I'm not putting out unsupported or internally generated random opinions here. (And I would be very leery of "educational" research in general. They are trying to look for the lost keys under the lamp post
 rather in the inconvenient dark down the street where they were lost.)

For example, it is still that case that the better reader you are, the harder it is to read on any computer screen, still today, and even the ones that don't flicker at all. We put a lot of effort at Xerox PARC to do the experiments and observations to understand what it takes to make readable electronic media (among other things, I was the original type designer and tester there for both bit-map screens and the early laser printers). One part of the story can be found in Tom Cornsweet's book on the modulation transfer function of human vision as related to stable reflective media. Another has to do with the tradeoffs between visual acuity, light sensitivity, saccades, scanning, and several other factors in the way human vision works.

I don't think anyone would accuse me of having tried to reinvent the wheel, or admonish me to try not to (but the range of random opinion
 out there is wide indeed). 

However, I am worried that the big propensity today is that so many people in both computing and education are "reinventing the flat tire".

Cheers,

Alan

The reason I told Steve a few years ago to make the iPhone screen at least 5" by 8" is that the small screens on phones are *really really bad* for good use in education (especially for children). This is amazingly not at all understood by a vast number of "educators".

Alan

Well....


Evidently "Steve" forgot to tell his developers and marketing departments. This is just a small sampling of what is out there:

Actually I would love to see some recent hard data from real educational research about the effects/affects of screen size (or type size?) on children.  We all know that primers begin children with large type and that the books progress to smaller type as the child gets older.  


However, some very bright children move to smaller type books ahead of their age cohort.  Is this harmful?  Should these children be held back for fear of damaging them? What does neuroscience and educational research have to say about this?
As an aside to developers, I notice Apple is already touting the "educational apps" that are available. Be sure you don't re-invent the wheel... unless, of course, it is a much better wheel! (Which I'm sure it will be.)
