Do teachers need to learn neuroscience?

Daniel Willingham rants in the Washington Post against Sarah D. Sparks' essay in Education Week:

Teachers don't need to learn neuroscience — or better put, teachers shouldn't need to learn neuroscience — to be protected from charlatans. Teachers need to learn things that will directly help their practice. Charlatan protection ought to come from institutions: from schools of education, from district central offices, and (potentially) from institutions of teachers' own creation.
