My takeaway from the video is that over time your rewards should start shifting from just awarding participation to rewarding higher-level thinking. I was genuinely surprised that stickers helped, but after a little thinking back I remember my science teacher putting stickers on my tests. It never made me super excited, but it did encourage me to continue my good work. 

By creating a positive atmosphere in her classroom and rewarding students for participating, this gives the students a lot more motivation to want to participate in class. This also makes the actual class time more engaging and fun for the students. 

The positive reinforcement really worked.  The student looked forward to getting their stickers.

Even in older schools it was good to see the students getting excited over stickers, because then they knew they were doing the right thing and the teachers knew and were paying attention to them. Also this teacher does an awesome job with verbal praising the kids because like she said that student raising their hand could have been one of the hardest things they did that day. Also she said " If you give them the time to be bored that is when the misbehaving comes into play". 

“Always show you mean business” carries a stigma that if a student does anything against the expectations of Ms. Hall then one will be able to handle the consequences that follows with those actions, or be praised for doing right and exceeding expectations of the teacher. Ms. Hall does a great job engaging in positive participation by letting her students know of the reward that will follow if their actions in the assignment exceed her expectations.
