BetterLesson was founded by a group of teachers from Atlanta and Boston public schools to connect educators and help them create, organize, and share their curricula. We are focused on aggregating and scaling the most innovative content and practices from high-performing teachers across the country.
Teachable Moment: Occam's razor has many applications but recently I used it as a coach for a First Lego League team. The children were making increasingly complex Lego contraptions and in order to reign them in, I introduced the concept of Occam's razor which didn't dismiss their complex efforts but challenged them to think of simpler solutions. After a while, all I had to do was simply say "is this consistent with Occam's razor" and they'd go back and find a better solution.
From Wikipedia: Occam's razor (or Ockham's razor), often expressed in Latin as the lex parsimoniae, translating to law of parsimony, law of economy or law of succinctness, is a principle which generally recommends selecting the competing hypothesis that makes the fewest new assumptions, when the hypotheses are equal in other respects. For instance, they must both sufficiently explain available data in the first place.
Teachable Moment: Mindstorms NXT is a great tool but figuring out projects and programs is very time consuming. This web site has some fun projects that help students explore a broad range of NXT projects.
If you have a LEGO®MINDSTORMS®NXT robotics kit, then this site provides free building instructions and downloadable programs for lots of fun projects.
Teachable Moment: NAIS has pulled together a great collection of resources for teachers interested in sustainability. Well worth poking around this web site and signing up for the Listserve.
Schools need to work toward environmental sustainability by becoming more green, reducing school and personal carbon footprints, promoting a commitment to life-long environmental responsibility, and incorporating environmental education into the curriculum
The Resource Area for Teaching (RAFT) started with an idea. What if:
Every child could get excited about learning through collaborative "hands-on" activities?
Every educator could obtain low-cost materials and the training to use them in "hands-on" projects?
21st Century learning skills developed through "hands-on" education could become pervasive and improve educational outcomes?
Teachable Moment:This TED video discusses the invention of the GPS as a perfect example of open innovative systems where "chance favors the connected mind". I also like it because it provides a good example of how innovation can be as simple as merely the inversion of our thinking... in this case, one group of scientists had discovered how to track a moving object in space from a fixed point on the ground... and another one pushed them to think about tracking a moving object on the ground from a fixed point in space.
