text: , could just make a difference on who wins so in other words, every state counts and every vote counts.                                             Im actually against the value of using technology to read students emotional expressions because thats would be a vialation of how you feel or like about something or someone. I think if you going use technology to calculate someones emotion they should aleast do it and keep it private. Im going to be telling you a little bit about why using technology to read student emotion is bad.
