This is all I can think about recently.
Well... when I'm teaching or lesson planning anyway.
Do you think you could teach without grammar explanation?
The reason I ask is most of the time problems students have or things they don't understand are usually a product of the teacher trying to work with grammar. We are taking the language out of context and trying to work with it.
sentence -->> question
sentence -->> negative
passive -->> active
as well as article+s+be+gerund+...
I'm finding context is lost causing loss of understanding and also we get a lot of unnatural combinations for the sake of working with grammar. Also, using grammar allows students to make language they can't understand (well, make it using the template we went over today.) Thus they may be able to form it correctly today, but because they don't understand the usage they don't retain it.
I haven't done all the research needed to really present the model for grammarless instruction, but...
If you couldn't use grammar, what would you do?
