1) Listening is not as easy as it sounds
If you break down this concept of interpretive listening into smaller parts, you will find that in order to get students to that goal of being able to actually INTERPRET what they are hearing, they first have to develop some more basic skills.
2) Assume nothing
Regardless of the level of student you teach, never assume that their skills are at a certain place just because they "should be" at that place. Unfortunately, "should be's" don't matter and will actually railroad your plans when you get down to the reality of what listening looks like in the classroom.
3) Differentiation does not have to be difficult
I admit, there are still times when I cringe at the sound of the word "differentiation" because to me it is just code for "more work". However, small differentiations can make goals reachable for a larger number of your students and assure that students at the bottom and the top are not getting left out.
So, let's start by breaking down interpretive listening and all the little parts and pieces that students need to be able to do.
