#32Where does the whole concept and idea behind Comprehensible Input (CI) come from?  In this episode I walk you through Stephen Krashen's Input Hypothesis that is part of his theory of second language acquisition that he calls the Monitor Model.  Krashen's Input Hypothesis is the origin of what what we are doing with Comprehensible Input today.What Is Comprehensible Input?Comprehensible input means that students should be able to understand the essence of what is being said or presented to them.This does not mean, however, that teachers must use only words students understand. In fact, instruction can be incomprehensible even when students know all of the words. Students learn a new language best when they receive input that is just a bit more difficult than they can easily understand. In other words, students may understand most, but not all, words the teacher is using.
