The core of elementary and secondary education should be the trivium --logic, grammar and rhetoric-- none of which are taught in government schools.
Mastery of this one book (The Trivium: The Liberal Arts of Logic, Grammar, and Rhetoric) would do far more for a child than 12 years of confinement in government schools. < /preaching to the converted>
Some charter schools (we have one in my state)are now offering a classical education.
A classical charter school in Colorado is the second highest ranked school in the state.
The trivium just makes so much sense. It's unfortunate that many school officials think classical education is elitist.
We have a lot of logic, grammar, and rhetoric in our family. Sometimes I consider running the van into a telephone pole just to get a little peace and quiet :-).
