text: In conclusion, his technology can change the way things are in the classroom. If a teacher can know how their students are feeling, they can improve the way they teach. If they improve the way they teach, students will be more ingaged. If studenets are more ingaged, then they are most likely to learn what is being taught and understand it.Honestly truth be told there is a valuable cause in this because alot of technology today will ask you to rate this website or did you like this song?.The computer will read only what u tell them. Although the computer cannot read how you really feel because sometimes people lie about what they do and dont like. So just because you rate that website a 7 doesnt mean you like it you might just want them to think its a good website. The computer would have to be very reliable and trusting for it to be valuable. The students these days is hard to tell because they just don't care anymore. If they don't care then there is no way to tell if they like something or not.
