Should teenagers work while they are students?
Basic to any understanding of the development of the current
education is not only the study marks the students make but also
the practical ability they have in the everchanging society. In my point of view, it is good for teenagers
have jobs while they are still students.
The most significant reason to support my opinion is the students
can put what they have learned into the usual life so that they can
apply it flexibly and freely. For example, a student is working at the
counter of a supermarket. Everyday, he counts the money,
calculates the bills and gives the changes to the customers. In this
case, this student will use the most convenient and considered math
method to solve the problem while working. The way he using
makes him have a deeper expression, a more skillful apply and raise
his speed of calculating.
On the other hand, teenagers having jobs while they are still students
can widen their horizons and improve their ability to communicate.
If a student has a job, he will communicate with all kinds of people
he meets while working and have the chance to know some parts of
the society that differ from his similar campus. During the working
time, this student will communicate with not only teachers,
schoolmates but also workers, drivers, managers and the like, whom
he probably cannot see in the campus. And then, he learns different
ways to communicate with different people and can get along well
with the all kinds of people. His ability to communicate will improve
effectively and efficiently. Even more, he will learn something new
for him by knowing the work style, job background and so on of the
people so that he knows more than the one has no jobs.
In a conclusion, I truly believe that it is dramatically good for
teenagers have jobs while they are still students. Because it is
natural, logic and make the students have a more meaningful and
colorful life by touching the current society.
