Reflection: Positive Reinforcement Macromolecules, part 1 - Section 2: Introduce New Material


Students enjoy showing what they know and I like to give them opportunities to demonstrate their knowledge and understanding during instruction.  Student responses to inquiry questions or checks for understanding allow both teacher and student celebrate learning.  A practice that I utilize as a quick motivator or reinforcement is I reward students in small ways like giving them piece of candy or simply, “Snap them up”.  “Snapping up” is something that I use in my classroom to recognize effort or success. I simply snap my fingers multiple times to indicate that I like the effort or the response. 

This is an effective way to recognize and celebrate students when they answer a question correctly.  If the response is not the correct response, I might say, “I like your effort so you get one snap for trying”. I also teach my students to “snap up” their peers when someone has made an effort or response that they feel is great.  I have had great success with this seemingly “goofy” practice with my high school students. I always smile when I hear them tell a classmate, “Hey, you didn’t snap me up” or “Don’t I get a snap?” when they feel they have contributed to the class discussion.
