positive reinforcement and negative reinforcements--examples and when you should you implement them
Positive reinforcements are those when you are giving a student reinforcement for a job well done. An example "Thank you Sally for picking that trash up.. I appreciate your effort." Often we find ourselves giving much negative attention. "Stop touching Sally". You must decrease the negative attention (e.g. "Don't touch each other", "Stop talking", "Sit Still"). A teacher should give positive reinforcement 4 times more than you use negative reinforcement.
For the most unruly students you need to find something positive almost every time you see that student. I use "I noticed..." statements. When I see a normally disruptive student being quiet and attentive after class I might say " I noticed today that you were really on-task/engaged/interested.." Then I might ask what about today's assignment really interested them. This allows for me to begin a dialogue to find out what makes this student "tick".
