Massive Storage
We used to be concerned with the amount of information we could store on our computers... I have seen school policy as late as 2008 that requires teachers to delete email (not only is that contrary to court order, but paying someone to throw away email is a waste of money!)
> I have 1 TB (that is 1,000 GB or 1,000,000 MB) hard drive attached to my computer. It cost less that $100.00. Let's do the math:
an email message contains about 10 kb, so we can store 100 emails in a megabyte (MB), 100,000 emails in a gigabyte (GB) and 10,000,000 emails in a terabyte (TB)--
that terabyte costs $100.00, so storing each email costs 1/10,000,000 of that... that is $1.00 to store 100,000 emails, or 1 cent to store 1,000 emails!
> Several authors have argued for "infinite" storage.
> YouTube- 20 hours of video uploaded every minute... 1,200 hours of video per hour... 28,800 hours of video per day.
The three major networks when I was a kid need 400 days to play as much video as is uploaded to YouTube every day!
> We Used How Much Information?

Why Should I Care? > ______ (fill in the blank with anything) is available on the web. > Are you the teacher who is the greatest middle school science lecturer (yes, I known this is an oxymoron... yes I know you don't teach science or middle school, bit you can fill in anything you like)? Great-- YOU CAN BE EMPLOYED FOR ONE MORE YEAR. > MIT cares and they are changing their curriculum. iTunesU. |
So, What Should We Do?
1) Change your focus... rather than lecturing (telling everyone everything they need to know), prepare them and interpret for them.
"Before you watch this, here is an outline..."
"What do you think the speaker meant when..."
2) Be aware... your digital dossier is not under your control!
