A friend who uses the ALG (Automatic Language Growth) approach to learn and teach languages recently asked a discussion group what reasoning, if any, is behind so much repetition of words when teaching with comprehensible input-based methods like TPRS (Teaching Proficiency Through Reading and Storytelling).
He had attended some language classes that used a lot of circling, a technique where the teacher asks many questions about a statement they’ve just made and solicits and provides answers.
For example, the teacher says “John is drinking coffee,” then asks: “Is John drinking tea?” (Students: “No.”) Teacher: “No, John is not drinking tea. Is John drinking coffee?” (Students: “Yes.”) Teacher: “Yes, John is drinking coffee. Who is drinking coffee? Is John drinking coffee?”, and so on.
From even this very brief example, it’s clear that the circling technique provides enormous amounts of repetition of language: “coffee” appears five times and the verb “drink” is used seven times.
However, my friend noted that even when a teacher made the meaning of a word clear and repeated it hundreds of times during a lesson, he usually wouldn’t remember it the next day.
