Will school science continue to teach the long-standing problem in cosmology about how dwarf galaxies form? I don’t know if/where schools teach the dwarf problem, but I do know curriculum and testing standards lock in old knowledge to what is taught and tested.
When I watched the video above this morning, I was only the 302nd person to do so. I found it on nature.com’s The Great Beyond science news blog.
In this week’s Nature Fabio Governato and colleagues present computer simulations that appear to have solved a long-standing problem in cosmology — namely, how the standard cold dark matter model of galaxy formation can give rise to the dwarf galaxies we see around us.
The beautiful animation above shows how exploding stars are a key force in shaping dwarf galaxies.
Educators are long overdue in dancing away from locking students into subject matter that fossilizes into printed textbooks and their matching tests. As I lamented this week, Texas is doing that right now for history.
The education establishment has judgmentally held the internet at arms length for way too long. It is time for teaching to step into the magnificent ballet of what is known by humankind in the open internet.
And wonderfully, it is now possible to put knowledge like the dwarf dance into the hand of every child.
