Why isnt this methodology used in the high schools and colleges and universities?
The textbook is the principal resource for teaching languages in these institutions. All of the grammar is taught through reading and writing. It provides pre-planned lessons and exercises, and it gives a teacher a lot of comfort to know what comes next in the book. The teacher becomes an explainer of what is provided in the text, and tries to package that information in a variety of innovative ways. Nearly all teachers believe that grammar must be taught through reading and writing. When a system comes along that teaches all of the grammar through listening comprehension and verbal fluency development, and without any textbooks or homework, there is a collective and universal gasp of heresy. Their focus on language learning is to teach reading and writing, not comprehension and speaking. We have taught over 14,000 students with this system, and the primary interest for more than 95% of them is to be able to understand and speak the language, and not learn to read and write it.
