In 21 century, technology is become advanced and necessary. All kinds of technology are around us. It is good to let us use some technology in class, like iPad or e-book, because we don't need to take a lot of stuff to school. We can just use the electronic thing to use in class, because it will not give the student a lot of heavy books. When they are doing the homework, they just need to do and turn in with electronic device instead of writing a lot.
   
    But there is still has some disadvantage of student use electronic device in class. Some of the students cannot control their mind, they said they are reading, but they always do other things that is not about the class in the device. Like they play games, watch videos, read novel and so on. Student will spend a lot of time in it, and they will get a bad grade on test. But the teacher have no way to know that what they are doing, so the teacher cannot help them, and the parents will get very mad from the teacher that their kids get bad grades.
   
    Anyway, I still want that we can use electronic device in class, I can do translate or scarch the information in class, we just need to control our mind that don't indulge on games or anything. This will always improve my grade.

Different and Same Between Hornbook and Kindle

    There is a lot of different between Hornbook and Kindle. Hornbook's screen is made with paper. Kindle's screen is made with high-technology. Hornbook is made with wood, but Kindle is made with plastic. Hornbook is just for young kid to study English, Kindle is for any kind of people, and you can download any kinds of newspaper or magazine.

But they still have the same characteristic. They are both for studying, and they are good for people.
