If world language teachers do 70% of the class in the target language, then the students hear the language and the students use the language for 70% of the time. If those teachers use comprehensible input through gestures, visuals, etc, then the teachers can increase the class to 90% or 100% of comprehensible input (ACTFL says teachers should talk 90% in the target language). What impact does changing from 70% to 90% have?
In a comprehensible input based classroom where 90% of the classroom is in the target language, each day students hear and use 20% more language than in a classroom with 70% language, Each week in less than four total classroom days of 90% input, the students have exceeded the amount of language heard and used in a 70% classroom. By the end of the week, they will have heard 1.4 days more of the target language. Within less than a month of 4 weeks, the 90% comprehensible input teachers will have picked up 1.4 x 4 days or 5.6 days extra. 10 months at 5.6 days = 56 additional days of hearing their world language.These teachers have actually increased the students learning time without increasing the school year.
Do you increase or decrease your students’ opportunity to hear and use the target language?
