It is an irrefutable fact that technology has made its mark on human civilization, giving us access to the most efficient and effective tools of the century. These methods can easily make your life easier. Although, modern machinery can do a lot for the community, it also brings many disadvantages. One major invention is being able to teach a class with a large number of students. Some of these innovations include devices such as laptops which are provided by the schools to help students with their studies. Also, instead of one on one teaching, students can watch a variety of educational videos during class time in order to help them learn a specific subject.
