I enjoyed watching the short video about comprehensible input.  It was pretty amazing how much more I understood once Krashen used the hand gestures to go along with his German speech.  I think I learned most of this in Linguistics, but I had kind of forgotten about what one needs to be successful in their L2. One aspect that helps with learning an L2 is self-esteem.  I have a Hispanic boy who does not seem confident in his abilities, and has developed a habit of clearing his throat every time he speaks, which does not happen very often.  He also has a habit of missing school, so his confidence would probably grow if he had more exposure, interaction, etc. 

I'm trying not to get sucked in to watching all of the other videos, but Krashen seems to have gotten funnier as he aged.  Does he have a great plan for teaching grammar other than just making sure the kids understand and are interested in the subject?  I may have to start writing mentor sentences about Angry Birds to help them understands nouns, verbs, and adjectives!!
