The Basic Flaws of Language Education

The Casa Shilohoo language program has a failure rate of over 95%. Why do they fail so much? What is wrong with language education all over the world? I know many of the reasons because I know the research on this topic, but it's interesting to experience this failure again as a student. In fact, I believe the fundamental problems are mental. The reason language schools fail is that they hold certain incorrect beliefs. These beliefs affect their teaching methods and attitudes.
