Chart week - Student laptops and wireless classrooms
Today is the second day of Chart Week here at Dangerously Irrelevant. Yesterday's topic, Internet access in public schools and public school classrooms, may not have been very exciting for many of you, but I needed to create some context. I am guessing that today's topic, student laptops and wireless classrooms, may be more interesting to most folks. All data are from the recently-released NCES report, Internet Access in U.S. Public Schools and Classrooms: 1994-2005.
Percentage of public schools lending laptops to students
As the chart below shows, about 10% of public schools reported that they lent laptops to students in 2005, about the same number as in 2002. In 2005, secondary schools (18%) were more than twice as likely to say that they lent students laptops than elementary schools (7%); these numbers also are the same as in 2002. In 2005, 15% of the schools with less than 6% minority enrollment said that they were lending laptops to students, while in schools with 50% minority enrollment or higher, only 7% said that they were lending students laptops.
Percentage of public school classrooms with wireless Internet connections
If you recall, yesterday's post showed that 94% of public school classrooms are connected to the Internet. The chart below shows the progress that has been made in converting public school classrooms to wireless (rather than wired) connections, arguably an essential prerequisite to having students use laptops meaningfully and frequently in the classroom.

Research by neuroscientists at MIT's Picower Institute for Learning and Memory helps explain how the brain regulates arousal.
The big day has come: You are taking your road test to get your driver's license. As you start your mom's car with a stern-faced evaluator in the passenger seat, you know you'll need to be alert but not so excited that you make mistakes. Even if you are simultaneously sleep-deprived and full of nervous energy, you need your brain to moderate your level of arousal so that you do your best.
A disturbing interview given by a KGB defector in 1984 describes America of today and outlines four stages of mass brainwashing used by the KGB.
- Bezmenov described this process as "a great brainwashing" which has four basic stages.
- The first stage is called "demoralization" which takes from 15 to 20 years to achieve.
- According to the former KGB agent, that is the minimum number of years it takes to re-educate one generation of students that is normally exposed to the ideology of its country.
When these companies compete, in the current system, the people lose.
- When a company reaches the top of the ladder, they typically kick it away so that others cannot climb up on it. The aim? So that another company can't compete.
- When this happens in the pharmaceutical world, certain companies stay at the top of the ladder, through broadly-protected patents, at the cost of everyday people benefitting from increased competition.
- Since companies have worked out how to legally game the system, Amin argues we need to get rid of this "one size fits all" system, which treats product innovation — "tweaks" — the same as product invention.
