text: Some people may not agree on many things, but maybe people could try this. Some adults worry about how student or there children are feeling and if they did the Facial Action Coding System it would be a way to express there emotions and tell how they really feel. It's as simple as a fake or real smile, the rising of an eyebrow, or even the squinting of your eyes. All of those qualities can tell you what your emotions are with using the Facial Action Coding System. Like the passage states, " The Mona Lisa demomstration is really intended to bring a smile to your face ", and so could the FACS. Seeing student down isn't pleasent and shouldn't be. Using the FACS is a way to tell, but don't put on a fake smile !
