Really cool new google lab feature "Correlate" There is so much to look at here. Try out the Drawing feature...pretty cool.
Draw an interesting curve, then click 'Correlate!' to find query terms whose popularity over time matches the shape you drew.
School of One math program in New York City as one of the top 50 inventions of 2009.
math teachers appear to agree that their main challenges center around gaining access to already-existing tools and how best to weave them into students’ education. And just because there’s a lot to choose from doesn’t mean all the programs possess the same ability to teach math on a long-lasting, conceptual level.
“Basically, the research says when students have the ability to engage with multiple representations of a problem, then they are better able to apply these tools with problem-solving and reasoning,
“Just having access to technology is not enough,” Mr. Ellis continued. “It’s the role of the teacher or of the curriculum that’s essential. Although kids are quick to pick [technology] up, they’re not that quick at learning to relate it to a mathematical concept.”
GNU TeXmacs is a free wysiwyw (what you see is what you want) editing platform with special features for scientists. The software aims to provide a unified and user friendly framework for editing structured documents with different types of content (text, graphics, mathematics, interactive content, etc.). The rendering engine uses high-quality typesetting algorithms so as to produce professionally looking documents, which can either be printed out or presented from a laptop.
The software includes a text editor with support for mathematical formulas, a small technical picture editor and a tool for making presentations from a laptop. Moreover, TeXmacs can be used as an interface for many external systems for computer algebra, numerical analysis, statistics, etc. New presentation styles can be written by the user and new features can be added to the editor using the Scheme extension language. A native spreadsheet and tools for collaborative authoring are planned for later.
