This year I have a horrible mix of students. I teach preschool special ed. with a mix of needs ranging from severe health/physical needs, to students who just have some mild artic delays. I've never had so many students just tell me "no" when asked to do something, and today was the worst it's been. It's not just 1 child, it's 5-6 children who when I go over and calmly say "john, start to clean up the blocks", and I get a head shake and a "no" while he continues playing, or I say "jane, sit on the carpet", I get a "no" and a smile. It's maddening. I've never had to work so hard before to get kids to comply with directions, and all my typical "tricks" aren't working (giving choices like "you can sit on the blue square or the red square" or "clean up the dolls or the food".) I feel like I do the same things I have in past years, giving positive reinforcement to those making good choices, using our class-wide behavior system to provide extra visual reinforcement, using visuals to help prompt, etc.. But all I get with every single direction is "no". How do you react when told "no" by a child?
