Does grades encourage students to learn?
Many people in the world share a belief that grades make students
work hard. I agree with the above statement because I believe that
high grades are more helpful in getting a bright future.
One of benefits of the high grade is that it promotes a learner`s
interest. Interest is the best motivation to encourage students to
learn. If a learner has a good score in English, he will find that
English is a beautiful language. For example I love to learn math,
because it brings me happiness when I get a high score in a math
exam. When I went to university, I select mach as my major.
The second reason is that schools give us a chance to learn
knowledge, why not try our best to get it. In our lives these
knowledge has important effect on our mind which need be wise
by a by. In addition, self-credit may be instruct by good marks. It is
also important to our life.
A further solid argument for the high grade is that it means a good
future career. Many companies would rather hire students who are
with high grades.
As far as I am concerned, I come to the notion that there are main
reasons why I support that grades encourage students to learn.
Firstly, high scores spring learner` interests.
Secondly, students get self-credit through it. Furthermore, A
good job may wait these students who have high marks.
