Additionally, machine learning applications, as seen
in studies like Gao et al. (2020), have further
enhanced the predictive power of these measures,
enabling real-time engagement and emotional
monitoring with high accuracy. Despite these
promising outcomes, the findings also highlight
significant challenges. External factors, such as
environmental conditions and physical activity, can
affect the reliability of HR and ST measurements, as
noted by Terriault et al. (2021). Similarly, the limited
sample sizes in certain studies, such as Cain and Lee
(2016), restrict the generalizability of results,
emphasizing the need for larger-scale investigations.
Moreover, ethical considerations surrounding the use
of wearable devices in educational settings require
further exploration to ensure student privacy and data
security.
In conclusion, the evidence presented in Table 1
underscores the transformative potential of
physiological measures for creating adaptive and

student-centered educational environments. By
addressing current limitations and leveraging
advancements in wearable technologies and machine
learning, future research can pave the way for more
inclusive and effective educational practices.
4.1 Practical Applications of
Physiological Insights in Education
The use of physiological data has also been applied to
tailor pedagogical approaches. Villanueva et al.
(2019) demonstrated how the intersection of identity
and physiological metrics in academic mentoring can
address diverse student needs, fostering a more
inclusive learning experience.
Lee et al. (2020) exemplified the use of EDA to
differentiate between public speaking and foreign
language anxiety, showcasing its utility in addressing
distinct stress contexts. Katmada et al. (2015)
proposed a biofeedback system that integrates EDA,
HR, and ST, highlighting its effectiveness in reducing
anxiety through gamified educational tools.
Furthermore, Jamal and Kamioka (2019) introduced
an emotion detection framework using facial ST and
HRV, achieving high accuracy without requiring
physical interaction, thereby expanding the scope of
non-invasive monitoring methods.
4.2 Building Emotionally Supportive
and Adaptive Learning
Environments
Physiological monitoring has proven instrumental in
promoting emotional engagement, which is critical
for deeper learning experiences. Loderer et al. (2020)
demonstrated that emotional engagement, as
measured through physiological data, fosters stronger
connections to educational material and promotes
long-term retention. Reid et al. (2020) highlighted the
value of real-time feedback in identifying stress
points during learning activities, enabling timely and
effective interventions by educators to alleviate stress
and maintain focus. The combination of physiological
metrics has shown promise in creating supportive
frameworks that improve resilience and academic
outcomes, especially in high-stress environments.
Rodríguez-Arce et al. (2020) explored the integration
of EDA, HR, and ST in designing frameworks that
support students' emotional well-being while
fostering academic success.
Eliot and Hirumi (2019) emphasized that
incorporating emotional and physiological metrics
into pedagogy enhances inclusivity and
responsiveness to individual learner needs, paving the
way for more equitable educational practices. These
advancements collectively underscore the
transformative potential of physiological monitoring
in advancing neuroeducation. By leveraging insights
from metrics such as EDA, HR, and ST, educators
can develop data-driven strategies to personalize
learning and address students' emotional and
cognitive challenges. The application of biofeedback
systems, emotion detection frameworks, and real-
time stress monitoring tools highlights the profound
impact of integrating physiological insights into
modern educational practices, ultimately promoting
student success and well-being.
5 CHALLENGES AND FUTURE
DIRECTIONS
The integration of physiological measures into
education presents significant opportunities, yet it
also faces notable challenges. Technical reliability
remains a key concern, particularly for wearable
devices measuring EDA, HR, and ST. External
variables, such as environmental conditions and
physical activity, can affect data accuracy, as
highlighted by studies that emphasize the need for
robust preprocessing techniques and adaptive
algorithms. Moreover, variability in sensor quality
and calibration across devices further complicates
widespread adoption.
The collection of physiological data in
educational settings, especially with minors, raises
significant ethical and privacy concerns. Effective
data governance and security are critical. Future
research must standardize methodologies, enhance
sensor accuracy, and refine machine learning models
to reduce bias in diverse environments. Large-scale,
longitudinal studies are needed for broader validation.
Overcoming these challenges is key to achieving
sustainable educational innovations.
6 CONCLUSIONS
This review underscores the transformative potential
of physiological measures in advancing
neuroeducation. By leveraging metrics such as EDA,
HR, and ST, educators can gain real-time insights into
student engagement, stress, and emotional states,
enabling adaptive and personalized learning
experiences. The integration of wearable
technologies and machine learning models enhances
Enhancing Learning with Physiological Measures: A Systematic Review of Applications in Neuroeducation

the feasibility of implementing these approaches in
diverse educational contexts.
Despite the promising applications, challenges
related to technical reliability, ethical considerations,
and scalability remain significant. However, ongoing
advancements in wearable technologies, multimodal
data analysis, and standardized frameworks offer
pathways to address these barriers. Future research
must prioritize inclusivity, ethical transparency, and
empirical validation to ensure the widespread
adoption of these tools.
In conclusion, physiological monitoring
represents a critical innovation in fostering
emotionally supportive, data-driven, and effective
educational environments. By bridging neuroscience
and pedagogy, this approach has the potential to
revolutionize how educators understand and respond
to the cognitive and emotional needs of learners.
