Teaching Foreign Languages in Schools The Silent Way. This unconventional method was developed alongside Afro hairstyles and platform shoes back in the 1970s by mathematician (yes, we said mathematician) Caleb Gattegno. It was based upon ideas outlined in his book “Teaching Foreign Languages in Schools the Silent Way,” published in 1963. Like most cultural events of the 60s and 70s, it was a reaction to previous approaches and methods that were considered excessively rigid and constricting. In the section “ESL Teaching books” this is a good book.
