We don't qualify for e rate as we are private. Non profit for disabled. We shopped but best deal in rural spot is t1 at $600 a month. Netflix tests OK now when no guest devices on our lan. I can't ban win laptops nor ban android phones of staff and students.

Students At Lynn University Get iPad Minis Instead of Textbooks

wallydallas when going e-book, let students pick the reader (192 comments)

well said Anonymous. Let the students pick the device to read the PDF or content. The content should be universal.

This does seem like a dirty trick to sell iPads. The mini screen is too small if reading lots of text is the goal. The college should have simply given students a mandatory fee and chance to pick from 2 large screen tablets and 2 laptops or prove that you can bring your Own fully compatible device.

The college has a concern and that's validated by the reader comments here. A lot of students try to go the cheap route and avoid full time access to their own book. I've taught community college and by the 3rd week most students with performance problems had limited access to a textbook. Some students can pull off great work without full textbook access, but that is rare.

again, nice point. A key point here is Universal access to content without restrictions on time, location or license. I still have some awesome JSTOR PDF research files in my google drive, because i had rights to keep the paper too. Aaron Swartz RIP. He would love to chime in here.

Students At Lynn University Get iPad Minis Instead of Textbooks

wallydallas Can reading in school be more engaging? That's? (192 comments)

Promising. Yes. Can the teachers make text assignments engaging? Unknown? I fully agree with the advantages of PDF files in grad school classes. I like Mr. Jellomizer I just did grad school and loved having both printed PDF and PDF files in my google drive. I wish I could have had all 3 on my laptop screen ( and sometimes paper ) My own papers, PDF readings assigned by Professors, and Textbooks used by most similar grad programs. The search feature alone was awesome. My work was done faster and at higher quality than many classmates. My concluding work and thesis was so easy with everything on screen.

I also teach K-12 and I am the IT guy at a school using ipads one-one. We had limited success with textbooks. We have students with disabilities.

Book or ebook? What can improve learning is the way assignments incorporate text.

If a teacher wishes to have 50 pages digested by 50 students have each of 50 students summarize one page and skim 49 pages of text and 49 summaries of fellow students. Give 25 keywords to 50 students and have them read all 50 pages but extract the best quotes related to their keyword. School should not be about reading x number of pages.

Technology is neither sedation nor salvation. That's my thesis title. We've got very little conclusive research about technology in education.

I leave you with a good quote from experts on research of student success in college.
>>>>quote >>>
"the degree of net change that students experience at the various categories of institutions is essentially the same. That is not to say that any one institution resembles any other institution in its power to affect learning. ...

What matters is.....
===================
the nature of the experiences students have after matriculation (admittance) :
the courses (content) they take,
the instructional methods their teachers use,
the interactions they have with their peers and faculty members outside the classroom,
the variety (diversity) of people and ideas they encounter, and
the extent of their active involvement in the academic and social systems of their institutions."

Bill Gates Promotes Vaccine Projects, Swipes At Google

wallydallas great LA Times quote (481 comments)

Thanks for posting the link to the LA times. Good data on the dirty secret of Gates and other "rich" folks trying to use money to solve poverty.

"Using the most recent data available, a Times tally showed that hundreds of Gates Foundation investments — totaling at least $8.7 billion, or 41% of its assets, not including U.S. and foreign government securities — have been in companies that countered the foundation's charitable goals or socially concerned philosophy.
This is "the dirty secret" of many large philanthropies, said Paul Hawken, an expert on socially beneficial investing who directs the Natural Capital Institute, an investment research group. "Foundations donate to groups trying to heal the future," Hawken said in an interview, "but with their investments, they steal from the future."

Bill Gates Promotes Vaccine Projects, Swipes At Google

wallydallas news links to validate Gates pharma game (481 comments)

I wanted to validate the claims that Gates is guilty. Gates related money is actually limiting the health of people in nations the West considers poor. If Bill Gates really wanted to save the lives of people in poverty he would agree that patents don't matter for medicine in many situations. It's a myth that progress in medicine depends on putting patents before people. We must allow generic and patent free drugs to reach more people, and it would not cut into the massive profits of the drug company stocks held by the Gates Foundation.

http://www.motherjones.com/politics/2003/06/mother-jones-daily-briefing-0?page=3
>> see the reporting by John Litchfield of the London Independent 2003
Litchfield quotes Doctors without borders and notes the lack of affordable generics

>> Read reporter Greg Palast
"let me let you in on a little secret about Bill and Melinda Gates so-called "Foundation." Gate's demi-trillionaire status is based on a nasty little monopoly-protecting trade treaty called "TRIPS" - the Trade-Related Intellectual Property Rights rules of the World Trade Organization. TRIPS gives Gates a hammerlock on computer operating systems worldwide, legally granting him a monopoly that the Robber Barons of yore could only dream of. But TRIPS, the rule which helps Gates rule, also bars African governments from buying AIDS, malaria and tuberculosis medicine at cheap market prices"
http://www.informationclearinghouse.info/article4103.htm

"The Bush Administration has also prevented a positive resolution to one crucial issue left unresolved at Doha. Currently, TRIPS allows countries to produce generic drugs through compulsory licensing, but requires that such drugs be used predominantly for the country's domestic market. That means that countries cannot export generic products thus produced - even to countries where there are no patents"
http://yaleglobal.yale.edu/vi/node/285

As an English intellectual property and antitrust lawyer I read the piece by David Resnik and Kenneth De Ville (2002) with both interest and surprise. It is startling to suggest that a country with the democratic credentials of the United States should, as a matter of public policy and indeed on apparently "moral" grounds, prefer private monopoly rights to the lives and welfare of its citizens.
http://muse.jhu.edu/journals/ajb/summary/v002/2.3smith.html

By pouring most contributions into the fight against such high-profile killers as AIDS, Gates grantees have increased the demand for specially trained, higher-paid clinicians, diverting staff from basic care. The resulting staff shortages have abandoned many children of AIDS survivors to more common killers: birth sepsis, diarrhea and asphyxia.

It's Not All Waste: The Complicated Life of Surplus Electronics In Africa

wallydallas Re:Lesson plans on e-waste, don't trust this repor (236 comments)

Hi Anonymous. You bring up some good points. I don't think anyone has all the answers here. The questions that remain are important. Yes, please share your Nairobi report showing 80-90% re-use. How did the report define "re-use" in 2006? Where are those devices now six years later? What data would we have If tracking devices were put on a random sample of those re-used units in 2006?

I read the GreenBiz URL regarding Peru. Peru can only track imported equipment that is reported. A lot of imported tech stuff is not reported. Greenbiz cites an article quote "The Environmental Protection Agency estimates roughly 400,000 tons of e-waste goes to recyclers every year, and that up to 80 percent of the materials sorted for recycling end up in operations in China, India, Southeast Asia and West Africa where it is disassembled and burned or dumped."

BAN and the EPA estimate that a majority of working and broken electronics sent to Africa and China are disposed of in ways that harm the environment. There is very little documentation to show that Africa and China have safe facilities to capture the toxins. Electronics arrive new and used, working and not.

It's Not All Waste: The Complicated Life of Surplus Electronics In Africa

wallydallas Lesson plans on e-waste, don't trust this report (236 comments)

I'm a teacher and I'd like to share some great free teaching lessons on e-waste
http://www.teachchange.org/ewaste

I very much doubt the claim in this report that 70% of our old electronics are "used". Any electronics sent to Africa or Asia are toxic, and 99% will eventually be dumped or burned in countries that have almost no enforcement and few laws.

E-waste researchers made 2 movies, and I created a 10 minute cut of both.
http://www.youtube.com/watch?v=EnqvfNstr_4
credit to http://www.ban.org
The movies are "Exporting Harm" and "Digital Dump" 2002 & 2005

A simple and great lesson for classrooms is to have students take apart dead computers and haul off the metal. Then show the e-waste movies or short version. Leave the other parts in the classroom for a few weeks and say you are having trouble finding a safe way to get rid of all the toxic stuff. There is even homework with a prize for students who inventory the most toxic e-waste in their own basements and closets.

I've traveled to Latin America to haul back e-waste others have donated. To use old technology the recipient need lots of electricity, and to safely process e-waste you need money and gasoline to haul it. This report is flawed in thinking that 30% is ewaste and 70% of used computers are "used".

peace out! . . sorry for posting this as anonymous in error.

Ask Slashdot: Is E-Learning a Viable Option?

wallydallas Salvation or sedation - join the dialog (349 comments)

Technology often sedates students and harms learning. Without excellent planing and implementation it decays into chaos or becomes masked as success because child and adult learners show fewer negative symptoms. Should we be following the lead of parents who install screens in the minivan?

Please join me. I'm researching technology and education. Does the prize of technology hide the punishment? More screen time and web only courses are not really building learing or relationships. There's very little agreement that technology boosts k-12 state test scores, even if you believe in them.

Please read or help me edit this draft google document: Sedation or Salvation - Education & Technology

https://docs.google.com/document/d/1umIJ_XanBrF4PAvPiB6EGGCBQ1Jxilsy3MzrXnQvr8I/edit?authkey=CKGo06sE

There's a huge technology & education trade show that rivals the size and hype of macworld. The ISTE conference is full of people who ignore the pitfalls noted by such reports as "Let them eat data" and "Fools gold". I want to collect more research on all sides of this topic. Contact me if you or people you know are questioning the myths of technology in education.

my short bio: After working at Adobe & HP I managed IT for six years at a technology high school in San Francisco. ( the 2nd Cisco academy ) I've taught middle and high school for 6 years full time in low income schools. I was once a proponent of one-one computers and laptops, but I've now changed sides after my first hand experiences with the wide array of symptops ignored by most educators. This includes but is not limited to the massive costs, and quickly growing mounds of obsolete computers thrown out by schools.

Here's a great cartoon that says it all:

Neil, Thanks for the amazing personal story. You're in a masters program, and you travel to 4 countries. You're from a privileged class and this post was about k-8 schools, Where 1 in 5 kids live in poverty, and most classrooms are getting more crowded. Neil, like you I took hybrid and web only classes where most students printed out the PDF readings. I put them into google docs. I can search, and I wish I could highlight the PDF and annotate in docs. My master's research is focused on this topic: Is technology in education a form of salvation or sedation. I invite people to join me in editing something I'm throwing together today. https://docs.google.com/document/d/1umIJ_XanBrF4PAvPiB6EGGCBQ1Jxilsy3MzrXnQvr8I/edit?authkey=CKGo06sE

When devices update - bandwith quota sucked dry

wallydallas wallydallas writes  |  about a year ago

wallydallas (1483081) writes "I'm close to a solution, but I wonder how other people block their many devices and operating systems from updating in working hours?

For example:

I'm the IT guy who blocks ipads from updating when school is in session because we are in a rural location. 3mbps is the best WAN we can buy. Devices can update after hours just fine. We do this with our router (DDWRT) by blocking MESU.APPLE.COM

Many guests bring in Windows 7 laptops, and I want to welcome them, but not their updates.

How can I block updates on Android Phones and Linux Laptops?

I have a 4G device at home, and I'd like to apply the same tricks 24 hours a day so that I don't use up the bandwith from my vendor. And my many home visitors should have their updates blocked.

Thanks, Wally"

Forced obsolescence - is it bloatware, scareware o

wallydallas wallydallas writes  |  more than 3 years ago

wallydallas (1483081) writes "I've got a really sturdy and very fast laptop that is 7 years old. It's got Ubuntu 8 and my web browsers run perfect, something I could not get even with a fresh XP re-install.

Google has halted updates to chrome, and every time I start it I'm forced to dismiss a very false message that my Operating System is obsolete.

Is this scareware? Bloatware? What do we call it when a powerful force in the universe labels great hardware obsolete?"

leave your PC on to extend it's life - Fail

wallydallas wallydallas writes  |  more than 4 years ago

wallydallas (1483081) writes "A lot of ignorance seems to be flowing from industry experts in response to the story about a school district with 5,000 computers using the SETI at home software. PC Mag and a Carnegie Mellon CS professor are spreading the myth that you protect your computer if you don't power off. "Most advice given on computers nowadays is don't power them down," I'm a teacher in a large district with far too many computers left on overnight because the IT staff have a near dictatorship. How does a powerless teacher fight an oppressive IT staff who will not cooperate with teachers who want computers shut down after a decent time without any user activity. These tools exist and have been vetoed with the myth that they do damage to the workstation hardware."
