This is a beefed up repost of an article from last week. It got mixed in with a lot of other posts and may have been overlooked originally (the queue is jammed again).
In my opinion this Invisibles idea is the very best thing I have seen in TPRS/CI instruction for years. It may not work with high school kids. That depends on how much the joy has been ripped out of their hearts at this point in their lives. It is a big middle school winner – really big at the sixth grade level, not so much at the seventh grade level, and even less at the eighth grade level as those kids (even eighth graders!) are now starting to show signs of a kind of group depression as things get worse in our schools as a result of all the robots running our schools now, gumming things up, sucking all the joy out of education.
