Tests show more students increasingly fluent in English

"At Turnbull Learning Academy, many Spanish-speaking children are taught English by learning Spanish.

If the California English Language Development Test results are any indication, this controversial method of bilingual teaching may be working for the San Mateo school, where more than 95 percent of the students are learning English.

The annual release of the California English Language Development Test showed 48 percent of Turnbull test-takers scored in early advanced or advanced levels of English proficiency — up from 15 percent in the 2001-2002 school year." - Inside Bay Area

This is a very interesting (and I believe) and good method for teaching English. The better you know you're native language, the easier it is to transfer that knowledge to your second language. I wonder if this kind of teaching will ever make it past all the hurdles and misconceptions that people will have.
