Earl W. Stevick, Adapting and Writing Language Lessons… (1971)
“ A nineteenth-century German, Gabelentz, observed that for elementary instruction the best language teacher is a ;talkative person with a limited range of ideas;. (in Jespersen 1904, p. 74) If a student meets too many words and too many new grammar structures too soon, he is overwhelmed. Yet students are motivated best by genuine use of the new language, and genuine use, by definition, can place no restrictions on vocabulary or on grammar. Gabelentz handled this dilemma by the way he chose teachers. How can this formula be applied to the developent of textbooks and other teaching materials? ”
