A movable scale that goes from very, very small to universe. A sliding scale that allows you to investigate. 

Discussion of the idea of the flipped classroom. Doesn't just introduce one approach but a variety of well thought out options, and how some schools are scaling the model. Musallam is worth reading.  I do have concerns that Hooper's videos are 25-30 minutes long in his model. I think he's missing the point as far as chunking information in smaller components and letting students interact with the content.  Not a perfect model but it is an innovation, and both teachers do a much better job of using key vocabulary well, introducing multiple representations intentionally and connected, and providing guides for students. Much better than I think Khan does in his videos. 

WorldWide Telescope is Microsoft's answer to Google Earth and Google Sky. It's pretty cool and does a lot of stuff that I don't understand but am sure someone interested in astronomy would love. I look at it and think about using the zooms of planets to have student calculate the size of some features knowing the scale. It's not utilizing the total power of the software, but it gets me in the door, makes it a cool activity for the students, and creates a little love to science in a math class. i can live with that!

"This report is based on evidence from a small-scale survey carried out between April and July 2009 in 35 maintained schools in England. It evaluates the extent to which the schools taught pupils to adopt safe and responsible practices in using new technologies, and how they achieved this. It also assesses the extent and quality of the training the schools provided for their staff. It responds to the report of the Byron Review, Safer children in a digital world."

Quora is an interesting tool and it looks like it is getting some attention from the journalism community. On Quora, people ask and answer questions, harnessing the power of the internet and scale. 

Some simple recomendations for using flip video in the classroom with specific tasks and ideas for implementation.

Great site for having students calculate some proportions and develop proportional reasoning from a variety of contexts. Based in KY but can still connect to many students.
