THE PROBLEM AND ITS SCOPE

INTRODUCTION

Rationale of the Study

Sleep deprivation occurs when inadequate sleep leads to decreased

performance, inadequate alertness, and deterioration in health. The reason why
people should have enough sleep is that it permits your body and mind to
recharge, taking off you refreshed and alarm once you wake up. A solid sleep
also makes a difference to one's body to stay healthy and fight off infections.
Without sufficient rest, the brain cannot work appropriately. This may disable
your abilities to concentrate, think clearly, and process memories. Understanding
sleep deficiency helps to get it how sleep works and why it's essential. The
capacity to operate and feel well whereas the conscious depends on whether
getting sufficient total rest and sufficient of each sort of rest. It too depends on
whether students rest at a time when the body is ready and prepared to sleep.

For human beings to function properly, sufficient sleep each night is vital.
Adults need on average eight hours of sleep. Sleep deprivation occurs when an
adequate amount of sleep is not being maintained. Overtime, a lack of sleep can
negatively affect a person’s physiological health, psychological health, and
cognitive function. It is important to investigate how sleep impacts the human
body and combats sleep deprivation.

On the other hand, younger individuals also need sufficient sleep. Sleep is
a central activity in adolescence and consumes more than one-third of the day.
As part of this issue on adolescent brains, the researchers will point out the
negative effect of sleep deprivation among the grade 12-STEM students in
Benedicto College, Technical Vocational Campus. Sleep benefits the brain and
promotes attentive memory and analytic thinking. It also recognizes the most
essential information to sharpen your thinking and solidify your learning. Sleep
also promotes expansive thinking that can stimulate creativity. Sleep is essential
for teenagers to study for exams, learn musical instruments, and acquire
specialized skills.

REVIEW OF RELATED LITERATURE AND STUDIES

Related Literature and Studies

Sleep plays a crucial role in physical and cognitive development, yet many
students suffer from chronic sleep deprivation. With academic demands,
extracurricular activities, and personal commitments, sleep often becomes a
secondary priority. This review aims to explore the negative effects of sleep
deprivation on students, focusing on academic performance, physical health, and
mental well-being.

Sleep is an inseparable part of human health and life and is pivotal to

learning and practice as well as physical and mental health. Studies have
suggested that insufficient sleep, increased frequency of short-term sleep, and
going to sleep late and getting up early affect the learning capacity, academic
performance, and neurobehavioral functions. Previous studies have indicated
that the quantity of sleep reported by individuals as delayed or inappropriate
sleep, waking up too late, especially at weekends and daytime sleepiness is
associated with compromised academic performance in children and adults.
Some studies have emphasized the relationship between delayed starting time of
classes and academic success. Reduced overnight sleep or altered sleep
patterns has been associated with severe drowsiness and failure in academic
success. In a study, people who had enough sleep compared to sleepved
individuals used innovative solutions twice as often when confronted with
complex mathematical problems. The chance of academic failure was as long as
one or more than 1 year in students with inadequate sleep compared to those
with proper sleep. People who sleep less and sleep during the day are more
prone to vehicle and work accidents. In some studies, sleep efficiency has been
considered as essential for recovery, cognitive processing, and memory
integration. However, lack of sleep is associated with emotional instability and
impaired concentration. In this regard, students are particularly at risk of
developing sleep disorders and development of the disorder among them has a
negative effect on their academic performance across different grades, However,
there is no consensus in this case and not all studies state that sleep disorders
yield a negative effect on academic performance. Eliasson (2010) believes that
the time it takes to fall asleep and waking up affect academic performance more
than duration of sleep does. Sweileh and colleagues (2011) also believe that
there is no relationship between sleep quality and academic success. Similarly, it
is claimed there is no relationship between the night sleep before the exam and
test scores either.

Adequate sleep is essential for optimal cognitive function and academic

success among students. Sleep deprivation has been linked to diminished
cognitive abilities, including impaired attention, memory consolidation, and
problem-solving skills, all of which are critical for academic performance.
Additionally, inconsistent sleep patterns can negatively affect grade point
averages (GPAs), as maintaining a regular sleep schedule is more beneficial for
academic outcomes than extending sleep duration on an irregular basis.
According to James Zeitzer (2016) having inadequate sleep can affect the
students’ performance the next, having two following nights of having less than
six hours could lead a student inactive and can cause dizziness for the rest of the
week. Researchers also found that staying up more hours before going to bed,
even if it is followed by a full night’s sleep the next day, are more related with
slower performance of the students. But going to bed an hour earlier than normal
sleep has a minor effect. The web-scale study is responsible for the perception of
the impact of sleep deprivation in the real world especially in students who are
prone to this kind of situation, where people compensate for lost sleep with extra
coffee and naps, and otherwise adapt to life circumstances that limit sleep.
Research by Lo et al. (2016) indicates that sleep-deprived students experience
diminished cognitive performance, particularly in areas related to memory
retention and problem-solving skills.
 The effects of sleep deprivation extend beyond cognitive performance,
significantly impacting students’ physical and mental health. Chronic sleep
deprivation is associated with weakened immune responses, increasing
susceptibility to illnesses such as colds and flu. Furthermore, insufficient sleep
has been linked to higher risks of developing chronic health conditions like
hypertension and obesity, underscoring the importance of regular, quality sleep
for maintaining overall health. According to a study by Hirshkowitz et al. (2015),
chronic sleep deprivation is linked to weakened immune responses, which
increases susceptibility to illnesses such as colds and flu. Bryant et al. (2004)
pointed out that sleep-deprived students are more likely to develop chronic health
conditions such as hypertension and obesity, further stressing the importance of
regular, quality sleep. Walker (2017) emphasizes that sleep is essential for the
body’s repair and growth processes, and sleep-deprived students are more
vulnerable to illnesses due to weakened immune systems. Inadequate sleep also
disrupts metabolic processes, potentially leading to weight gain and hormonal
imbalances. Prolonged sleep deprivation increases the likelihood of long-term
health issues such as hypertension and cardiovascular diseases, further
complicating the academic and personal lives of affected students.

Emotionally, sleep-deprived students are more prone to anxiety,

depression, and mood swings, which can adversely affect their social
relationships and overall well-being. Elevated stress levels resulting from
inadequate sleep can further exacerbate mental health issues, creating a
negative feedback loop that impedes both sleep quality and emotional stability.
According to Becker et al. (2015), students who suffer from chronic lack of sleep
are more prone to anxiety, depression, and mood swings, which negatively affect
their social relationships and overall well-being. Sleep-deprived students are also
more likely to experience heightened stress levels, which can exacerbate existing
mental health issues. This can create a negative feedback loop, where stress
impedes sleep, and lack of sleep further aggravates stress (Garett, Liu, & Young,
2018).
 According to Leodinas (2012), every student should have about eight to
ten hours of sleep before taking an examination to have a better performance
and adding a nap in the afternoon will also help improve your memory. The more
we study the effects of sleep loss, the more we can find the importance of a good
sleep resulting in achieving better memory and improved learning. Sleep loss
means mind loss. It binds learning in many ways. It reduces critical thinking,
messes up memory and mood, retards reasoning, and shutters quantitative skills.
Furthermore, sleep is a vital necessity for people to live a healthy lifestyle in
which they can function well and think properly. It helps with memory
consolidation, learning, decision making, and critical thinking (Gilbert & Weaver,
2010). Therefore, sleep deprivation is necessary for keeping these cognitive
functions at an optimal level for performance wherever the person may be,
whether it be at work, home or even school. Unfortunately, not everyone gets
enough sleep to function properly throughout the day. These poor performances
as a result of poor sleep quality and sleep deprivation are especially evident
among college students. Since college students have such busy work, school,
and social schedules to keep up with their sleep cycles become negatively
affected by it. They tend to have irregular sleep cycles on the day of the week
and report this satisfaction with sleep because of poor sleep quality (Gilbert &
Weaver, 2010).
Theoretical Background

This research is anchored on Cognitive Load Theory (Sweller, 1988),

which is according to John Sweller that learning is affected by the amount of
information a learner’s working memory can process simultaneously. According
to this theory, cognitive load is divided into three types: (1) Intrinsic Load: The
complexity inherent in the material being learned. (2) Extraneous Load:
Unnecessary cognitive effort due to poorly designed instructional methods. (3)
Germane Load: Mental effort directed towards learning and understanding. Sleep
deprivation can negatively influence cognitive processes, increasing the overall
cognitive load and reducing the capacity for meaningful learning. Sleep is
essential for cognitive functions such as attention, memory consolidation, and
problem-solving—all crucial elements for academic performance in STEM
education. According to cognitive theory conduct is influenced by mental
functions such as memory, perception, and problem-solving. Lack of sleep can
affect these processes, which can result in poor academic performance. Sleep is
essential for the best possible cognitive functioning (Beck, 1967; Ellis, 1962).
Sleep deprivation affects cognitive function, which impacts students
 understanding, analyzing, and memory of information, resulting in poor academic
achievement (Curcio, Ferrara, & De Gennaro, 2006).

Theoretical Framework

The study relies on the published work of John Sweller (1988) about the
Cognitive Load Theory. In this theory, it is divided into three types of loads:
Intrinsic Load, Extraneous Load, and Germane Load. According to cognitive load
theory, the effect of sleep deprivation affects the learning adaptability of a student
and has a negative influence in their mental functions such as memory,
perception, and problem-solving. The sleep deprivation of a student can result in
poor academic performance. Overall, the study’s output is to recognize the
negative effect of sleep deprivation among student’s academic performances.
 THE PROBLEM

Statement of the Problem

Sleep deprivation is a severe problem among Grade 12 STEM students.

Many students do not get enough sleep, often averaging only 4-7 hours per
night. This lack of sleep makes it hard for them to focus on class because of
drowsiness, and to complete the assignments, and to perform well in school and
on the tests. The outcome of sleep deprivation leads to feeling of tiredness and
stress, which further affects their ability to adapt and absorb added information or
knowledge. This study aims to identify the “The Negative Effect of Sleep
Deprivation Among Grade 12 STEM Students in Benedicto College Technical-
Vocational Campus”. Specifically, this study sought to answer the following
questions:

1.) What is the student’s demographic profile in terms of?

1.1 Sex
 1.2 Age

2.) How many hours do you spend working on your schoolwork?

2.1 Less than 3 hours

2.2 4 to 6 hours

2.3 More than 6 hours

3.) How many hours do you sleep every day?

3. 1 Less than 5 hours a day

3.2 5 to 8 hours a day

3.3 More than 8 hours a day

4.) How does sleep deprivation affect student’s academic performance?

Hypothesis

After the research literature review, a predicted hypothesis that researchers

assume in this study. Specifically, the researchers suppose that;

(HO1) STEM students recognize the negative effect of sleep deprivation on their
lifestyle especially on their academic performances.

(HO2) most of the students know how to avoid sleep deprivation with the help of
time management, and clearing and setting their schedules.

(HO3) there will be a probability of small percentage of students affected on

having sleep deprivation on their academic performances.

Significance of the Study

This research on The Negative Effects of Sleep Deprivation Among Grade

12 STEM Students in Benedicto College is essential in understanding how lack
of sleep impacts the well-being, academic performance, and overall quality of life
of these students. By exploring the specific challenges faced by Grade 12 STEM
students, the researchers aim to provide a clearer picture of how sleep
deprivation affects their cognitive functions, emotional stability, and physical
health.

The findings from this study will benefit several groups:

The students: The knowledge that will be gained in this study will enable the
students to be aware of how sleeplessness affects their behavior in terms of
academic excellence. This will give awareness of the importance of sleep and
how it plays a role in their life, most especially in their health and education.

The teachers: This serves as a revelation to teachers unaware of the extent of

sleep deprivation among students and teachers. This will also help them to
create conditions to help them remind their students how important sleep is. They
will be able to develop and learn how to prevent sleep deprivation.

For Educators and school administrators: it can help use the insights to
implement better support systems, such as manageable workloads and
awareness programs that emphasize the importance of rest.

The Parents: Parents will benefit also from this by realizing that they should give
guidance and discipline to their children. Through this study, parents will become
aware and understand that sleep deprivation can affect their children, especially
their studies. They will be able to know that they should give full parental
supervision to their child.

The future researchers: The findings of the study will serve as reference
material and a guide for future researchers who wish to conduct the same study
related to the effects of sleep deprivation on the academic performances of the
students.
This study aims to create a healthier, more balanced academic environment for
Grade 12 STEM students at Benedicto College, ensuring that they can achieve
their fullest potential without sacrificing their health and well-being.

Scope and Limitations of the Study

The primary focus of this study is to point out the negative effect of sleep
deprivation among Grade 12 STEM students in Benedicto College Technical-
Vocational Campus, which will serve as the respondents. This study will utilize a
survey method to gather the data. Therefore, the researcher will ask 75% of
students on each section through a self-made printed survey questionnaire, and
these will be answered based solely on their own opinions and perceptions.

Moreover, the researchers make use of a single set of self-structured

survey questionnaires in which the items were closed-ended. The questionnaire
is comprised of the following parts: Part I deals with the profile of the respondents
such as age, sex, name, and the next following questions. Part II examines the
respondent’s reasons for having sleep deprivation. Part III refers to the
respondent’s quality of sleep having a sleep deprivation. Respondents are asked
to rate their quality toward their sleeping using a 5 – point Likert scale ranging
from strongly disagree (1) to strongly agree (5). Lastly, the selection of
respondents will be done through a random sampling.

RESEARCH METHODOLOGY

Research Design

According to McCombes (2019), "Descriptive research aims to accurately

and systematically describe a population, situation or phenomenon." Therefore,
the study will use a descriptive research methodology to examine the variables
that may potentially impact the students' conduct. To investigate one or more
variables, a descriptive study design can be used using a variety of research
techniques. The researchers will use the above-mentioned research design to
assess and gather the Grade 12 STEM students' answers to their self-made
questionnaire and their viewpoints, views, and impressions of the study. In this
instance, descriptive research will go beyond data collection and tabulation. In
this scenario, descriptive research would be understanding aspects like
interpreting the relevance of what is described in addition to collecting and
arranging the data. As a result, classification, assessment, and interpretation will
frequently come up in the description. In this study, the researchers will collect
information using questionnaires.

Flow of the Study

The study's flow will begin at the input phase, as depicted in Figure
2, where researchers will ascertain the negative effects of sleep deprivation on
student’s academic performance. The "Notification Letter for Requesting
Research Advisor" will be given by the researchers to the assistant principal,
research teacher, and chosen research adviser during the procedure phase.
Additionally, the respondents will receive survey questions from the researchers.
The output step has not yet been included.

 Research Environment

The locale of the study is Benedicto College (BC) Technical-Vocational

Campus. It is a private non-sectarian educational institution located in Banilad,
Mandaue City, Cebu, Philippines. The campus was established in 2017 by
businessman and former Philippine foreign ambassador Francisco L. Benedicto.
The founder's objective in building the school is to extend affordable education
for everyone, especially to those who are in need, to mobilize lives into
improvement.

In 2000, the school offers undergraduate programs through its six

colleges: Arts and Sciences, Business Management, Computer Studies,
Education, Hospitality Management, and Engineering. In 2009, the school
opened its basic education department, it caters preschool, elementary, and
junior high school curriculum. In 2015, the school opened K-12 programs for
senior high schools which offer STEM, HUMS, ABM and GAS strands. Currently,
Benedicto College is continuing to expand and improve programs and facilities
for the introduction of new courses for the school year 2024-2025.

Benedicto College grade 12 STEM students are designated at the

Technical-Vocational building, specifically found at the third floor of the campus,
room numbers 304, 302 and 301. STEM grade 12 students are divided into three
(3) sections: STEM A (Talisay), STEM B (Toledo), and STEM C (Minglanilla).

Figure 3 shows the Map of Mandaue City where the study venue is.

Research Instrument
 To gather the required data and insights, the researcher will employ a self-
made survey questionnaire aimed at identifying and analyzing the negative
effects of sleep deprivation among Grade 12 STEM students at Benedicto
College. This survey will serve as the primary data collection instrument and will
be conducted through face-to-face interactions with participants.

The instrument consists of a single set of closed-ended questions. Researchers

will gather demographic details, such as the respondent's name (optional), age,
gender (male, female, prefer not to say), and section. The survey comprises the
following sections, Part I collects demographic information, including name
(optional), sex, and age. Part II Identifies reasons for sleep deprivation, such as
online gaming, social media, health issues, academic workload, and
extracurricular activities. Part III Assesses sleep quality and its impact on
academics and well-being, using a 5-point Likert Scale from Strongly Disagree
(1) to Strongly Agree (5). This structured questionnaire enables the researchers
to analyze the extent of sleep deprivation's effects on students' academic
performance and health.

DEFINITION OF TERMS
 The terms and variables used throughout the literature review need to be
operationally defined for clarity and deep-seated understanding. These terms
are:

Academic Performance

Academic Performance. According to Ballotpedia (n.d.), academic

performance is the measurement of student achievement across various
academic subjects. Teachers and education officials typically measure
achievement using classroom performance, graduation rates and results
from standardized tests. It refers to how students handle their academics
and how they cope with or complete the assignments assigned to them by
their teacher.

Effect

Merriam Webster (n.d.). something that inevitably follows an

antecedent (such as a cause or agent): result, outcome

Senior High School

Collins (2022) define Senior High School as a school attended after

junior high school and usually consisting of grades 10 through 12. Senior
High School consists of two (2) additional years of grade schooling, Grade
12. Grade 12 STEM, A Batch A and B students will participate as
respondents. Sleep Deprivation. Cleveland Clinic,

Sleep Deprivation

It is where you are not sleeping enough, or you are not getting
good, quality sleep. When it is severe or happens over an extended
period, it can cause very disruptive symptoms that interfere with even the
most routine activities.

Inadequate
 Merriam Webster, not adequate: not enough or good enough
Drowsiness. Medline plus.

Drowsiness

It refers to feeling sleepier than normal during the day. People who
are drowsy may fall asleep when they do not want to or at times which can
lead to safety concerns.

 APPENDIX D
REQUEST LETTER FOR CONDUCTING THE RESEARCH

SEPTEMBER 30, 2024; Monday

To: Dr. Jhoner D. Montegrande
Principal
Senior High School
Benedicto College

Sir/ Madam:
We are students from Grade 12 Cordova of Benedicto College, senior high
school department, with the teacher of our Practical Research 2, Mrs, Jessah I.
Manatad and our research adviser, Mr. Nicasio Balbontin. We are writing the
request letter in your good office for permission to conduct our research study
entitled, The Negative Effects of Sleep Deprivation Among Grade 12 STEM
Students in Benedicto College, inside your institution. Our study aims to
examine how sleep deprivation impacts academic performance and well-being
among our fellow Grade 12 STEM students.

We plan to distribute a short, anonymous survey to students, ensuring that

participation is voluntary and confidential. The insights gained will help
understand student challenges and may benefit the school in addressing student
well-being.
We kindly seek your approval to administer the survey and access any
necessary resources. We would be happy to discuss further details at your
convenience.
Thank you for your time and consideration.
Yours truly,
Mary Jhanabelle M. Andales Kimberly L. Balbuena
