CASTLE has a new blog! Check out


Some of you have noticed that CASTLE has a new blog: 1to1 Schools. We're excited about this new venture, which is meant to highlight news, stories, videos, and other resources related to elementary and secondary 1:1 laptop programs.


1to1 Schools is a group blog. For example, check out Nick Sauers' series on using John Kotter's 8–stage change process as a model framework for schools that are considering 1:1. Or his post on banning boredom, not laptops. Nick and I also have been on the road with our Flip camcorders, making videos of educators who are involved in laptop programs (see, e.g., our chats with Wynn Draper-Bryant and Marge Beatty).


Pamela Livingston, author of 1-to-1 Learning: Laptop Programs That Work, recently had two posts about an international survey of students in 1:1 programs:


She also wrote recently about how laptops are NOT for listening.


Blair Peterson, another occasional contributor, has noted that we should be prepared for the expected opposition to laptop programs.


The blog is a work in progress - and like many new blogs we're still working on finding our voice - so please contact us if you have suggestions. If you'd like to be a contributor (or know someone else who'd be a good writer for us) please let us know that too.


Happy reading!

Harvard: Men who can do 40 pushups have a 'significantly' lower risk of heart disease

Turns out pushups are more telling than treadmill tests when it comes to cardiovascular health.

Airman 1st Class Justin Baker completes another push-up during the First Sergeants' push-up a-thon June 28, 2011, Eielson Air Force Base, Alaska. Participants were allowed 10 minutes to do as many push-ups as they could during the fundraiser. Airman Baker, a contract specialist assigned to the 354th Contracting Squadron, completed 278 push-ups. (U.S. Air Force photo/Airman 1st Class Janine Thibault)
Surprising Science
  • Men who can perform 40 pushups in one minute are 96 percent less likely to have cardiovascular disease than those who do less than 10.
  • The Harvard study focused on over 1,100 firefighters with a median age of 39.
  • The exact results might not be applicable to men of other age groups or to women, researchers warn.

U.S. reacts to New Zealand's gun ban

Politics & Current Affairs
  • Gun control supporters are pointing to the ban as an example of swift, decisive action that the U.S. desperately needs.
  • Others note the inherent differences between the two nations, arguing that it is a good thing that it is relatively hard to pass such legislation in such a short timeframe.
  • The ban will surely shape future conversations about gun control in the U.S.
