Does grades encourage students to learn?
Over millennia, the grades from tests or examinations have been
using to evaluate the students` performance, although many people
debate that it may neglect students` abilities outside the textbook.
However, we cannot find a sound method to replace it. As a result, I
personally agree with the statement for the following reasons.
To begin with, the grades are the results through fair competition.
Students gain their deserved grades after reading over the
designated contents. The result reflects their understanding of the
knowledge in class and the grades give students a chance to inspect
what they have learned. Whether he gets high scores or not, at least
he knows his deficiency through the fault.
Secondly, grades can give students the sense of achievement, which
is the biggest motivation for learning. Studies show that confident
students will learn better than others. If students constantly maintain
good grades, he will study harder and harder. For those who usually
do not get good grades, they also have a chance to reverse from the
adversities if they study harder.
Last but not least, grades develop a responsible attitude for
students, because they must bear the failed results due to his
idleness and distraction. By comparing with their counterparts,
they not only know the reality they face, but learn how to catch up
from behind, because we know, sometimes, the frustration gives us
more than success.
From the reasons above, we can easily conclude that grades encourage
the students to study. An old saying said
o pain, no gain. ?Good
grades are the reasonable results of hard work. We must keep asking
ourselves not whether we seize good grades, but whether we study
hard.
