I Introduction:

In Western countries, where time is considered one of the most valuable assets of workers, the

concept of "part-time" was born quite early Although it has only been around for less than a

decade in Vietnam, with the globalization trend, "part-time" has become a "hot" keyword

Part- time jobs was born as an effective solution for job seekers to maximize their time and

earn more money People work "part-time" for a variety of reasons, including the desire to gain

experience for future jobs, the desire to exchange and learn, the desire to constantly change the

working environment, and the desire to renew themselves every day Therefore,, "part-time"

becomes a benefit, a real hobby, not just a way to make money

In recent years, "part-time" job has begun to come to students more actively in recent years,

thanks to the outstanding development of the Internet More than anyone else, "part-time" hits

hard on students, not only because they always need an income to add to their monthly supply, but

also because this class is always ready to work with enthusiasm and dynamism typical of youth

Students are compared to "time kings", so it is also an opportunity for students

to use their free time to gain experience before entering a professional working environment

Besides, if you do not have the right orientation about part-time jobs and future goals, but only

focus on immediate goals, forgetting the main task of studying, you cannot balance between

studying and doing part-time jobs will affect the academic results, health, lifestyle of students

So, part-time jobs can be considered a "double- edged sword" The question is how do students

do part-time jobs to earn extra income, have the opportunity to be close to reality, perfect their

skills without being "alienated", negatively affecting their learning, practice morality and

lifestyle

Our research team, as students , chose the topic "Effects of part-time job on college students'

lives in Hanoi" in the hopes of generating some ideas and orienting students in choosing

time jobs, proposing some solutions to help them balance study and time work, so that

part-time jobs truly support students' learning and self-improvement, as a preparation for them to

conquer the future

-The number of people working from home during the period of social distancing accounted for

52.9%, that led to the drop in pupils living in rented house or dorm with nearly 4% The number

of people still renting houses is still there when Hanoi implements social distancing with

36.96%

- From the above numbers, initially, the research team predicted that part-time jobs would be considered

to have less impact on learning because many jobs take place in the online environment so students can reduce time and costs for students during pandemic period

Social awareness raising: 58.5%

- Beside that, there were some reports showed that working part-time job effected the efficiency of studying at school:

Knowledge acquisition improvement: 19.5%

- On average, each person spends about 2 hours on self-study

- Most students, even if they have part-time jobs, they still spend 1 to 4 hours on self-study, which can

also explain that even if they work, it doesn't affect their studies and their average GPA that from good level or

higher

- Overall, the extent that work affects schooling, health, or relationships on average is rated positively.

- It can also be seen that part-time jobs bring many benefits to students

- Satisfaction level is the majority at level 3 and level 4, showing a very positive influence on

relationships

- Regarding the effect on health, the majority of people at level 3 are positive, but the number of people

who choose level 2 is at the highest effect on health out of the 3 tables This may be the case for people who work 2

or more jobs because having to work too much is also very bad for their health

- As for the influence on learning, most of them are very positive influences at level 3 and level 4,

accounting for 80% of the survey Show that part-time jobs help them study better, having a place to practice lessons

in class helps them understand the lesson and study better Prove that their GPA is mostly from pretty good to

majority

- In 3 graphs, it can be seen that going to work has a positive influence on learning and relationships

mainly (80% are rated at 3 and 4) are highly appreciated by the students and the efficiency of going to work

- Dependent Variable: GPA => Average GPA during the period in university

- Independent Variables:

· work => Average working time per day

· study => Average self-study time per day

R-square have some limitations

 Using Adjusted R-square

R−square= Residual ∑ of squares

- R-square*adjustment factor = Adjusted R-square = -0.014

The value of adjusted R-square is too small, so this model is not so good because it seems that

the dependent variable mostly can not explained by 2 independent variables

- The value of Std.Error of the Estimate is 0.91034  This value is not big  This might be a good

Dependent Variable: Aver_GPA

- Linear regression: GPA = 3.012 + 0.15study – 0.008work

On average:

If student doesn’t have a job and self-study, his/her average GPA will be 3.012

When student increases his/her self-study time by 1 hour, his/her average GPA increases by 0.15

When student increases his/her working time by 1 hour, his/her average GPA decreases by 0.008

- Absolute value of standardized coefficients of β1 (0.023) is higher than that of β2 (0.019), so the average

self-study time has more effect on the average GPA than the average working time

- Test for hypothesis:

+) T-test for β1:

H0: β1= 0H1:β1≠0Because sig β1= 0.789 > α=0.05 => not reject H0 => β1 might be equal 0 and the average self-study time might make no sense to Average GPA

Because sig β2 = 0.828 > α=0.05 => not reject H0 => β2 might be equal 0 and the average working time might make no sense to Average GPA.

Comment: At first, we expected that there was a positive correlation between self-study time,

working time and GPA If what we expected has enough evidence to be proved that it is right,

students can look at our research and make most suitable decisions for them However, as the

results which are estimated and explained by those tables above, there’s nothing at all All the

estimated results are insignificant that means GPA of a student is almost unaffected by his/her

self-study time or the amount of time he/she goes to work

c. Dependent Variable: work

- Linear regression model: work = β0 + β1study + β2allowance

- Null hypothesis:

H0:β1=β2=0H1: At least 1 value of β1 and β2 not equal 0Test for hypothesis by using sig (p-value)Sig = 0.9 > α=0.05 => not reject H0, there’s not enough evidence to prove that at least 1 value of β1 and β2 not equal 0

Coefficients a

If student doesn’t spend time on self-study and has no allowance, his/her averageworking will be 4.101.

When student increases his/her average self-study time per day by 1 hour, his/her average working time per day increases by 0.007 hour

When student’s average monthly allowance is increased by VND 1 million, his/her average working time per day increases by 0.043 hour

- Absolute value of standardized coefficients of β1 (0.004) is lower than that of β2 (0.039), so the averageself-study time per day has less effect on the average working time per day than the average monthly allowance

- Test for hypothesis:

+) T-test for β1:H0:β1= 0H1:β1≠0Because sig β1 = 0.961 > α=0.05 => not reject H0 => β1 might be equal 0 and the average self-study time per day might make no sense to Average working time per day

+) T-test for β2

H0:β2=0H1:β2≠0Because sig β2 = 0.652 > α=0.05 => not reject H0 => β2 might be equal 0 and the average monthly allowance might make no sense to Average working time per day

Comment: On the other hand, in the second model, average working time per day is expected to

decrease when both average monthly allowance and average self-study time per day increase

However, same conclusion happened that there was no correlation among them From our

perspective, this faulty maybe due to lack of proper theories when developing variables
