Many people think that History is an essential subject to learn in school. Whilst others believe that, in this contemporary world, Subjects similar to Science and Technology are most needed. However, Individuals have these notions because they believe that it is important for students to know about past events and to learn from their mistakes; in contrast, according to other's beliefs, adequate knowledge of Technology and Science is necessary for people to invent new things and to make life easier. Nevertheless, In my opinion, Educating schoolchildren about technological and scientific subjects should be focused on most.
