ABSTRACT
This study explores the impact of Project-Based Learning (PBL) and Universal Design for Learning
(UDL) on English as a Second Language (ESL) acquisition, focusing on how these approaches influence
student motivation, participation, and language proficiency. A quasi-experimental design was
employed, with control and experimental groups, to assess the effectiveness of these methodologies.
Data were collected through surveys, pre-and post-tests, and qualitative classroom observations. The
results indicate that both PBL and UDL significantly enhance linguistic skills, particularly in reading,
writing, and oral expression. These strategies also foster increased student engagement, motivation, and
collaboration, contributing to a more dynamic and inclusive classroom environment. The study shows
that the integration of PBL and UDL supports not only language development but also the creation of a
supportive learning atmosphere that meets diverse educational needs. These findings underscore the
potential of PBL and UDL to improve ESL instruction by encouraging active participation and
collaborative learning. The study concludes with pedagogical implications, emphasizing the importance
of professional development for educators in active and inclusive teaching strategies. It also suggests
avenues for future research to refine the use of these methodologies in various educational contexts,
ultimately aiming to enhance ESL outcomes across diverse linguistic and cultural settings.

INTRODUCTION
The schooling of foreign languages is a dynamic and continuously evolving field, driven by the necessity
to adapt to diverse student needs and the rapid advancements in educational technology and
methodologies. In today's globalized society, acquiring a second language is not merely an academic
endeavor but a crucial skill that enhances personal, cultural, and professional opportunities. The
complexity of second language acquisition lies in its requirement to integrate linguistic, cultural, and
cognitive skills simultaneously—a challenge that traditional methods of instruction may not fully
address (Vygotsky, 1978).
Innovative instructional approaches have emerged to meet these challenges, with Project-Based
Learning (PBL) and the Universal Design for Learning (UDL) framework standing out as particularly
promising methodologies. PBL is characterized by its emphasis on real-world problem-solving and the
creation of authentic projects that engage learners in meaningful tasks and enhance the critical thinking
of students. This approach shifts the focus from rote memorization and passive reception of information
to active learning, where students are encouraged to collaborate, think critically, and apply their
knowledge in practical scenarios (Thomas, 2000; Bell, 2010). By contextualizing language use in real-
life situations, PBL not only enhances linguistic proficiency but also fosters the development of critical
soft skills such as teamwork and collaboration, communication, and creativity (Krajcik & Blumenfeld,
2006).
Adding PBL, the Universal Design for Learning (UDL) framework offers a flexible and inclusive
approach to education that caters to the diverse needs of learners. UDL is grounded in the principle of
providing multiple means of representation, engagement, and expression, ensuring that all students—
regardless of their learning styles or abilities—have equitable access to the curriculum (Wiggins &
McTighe, 2005; CAST, 2018). In the context of English as a Second Language (ESL) education, UDL
promotes differentiated instruction, enabling educators to tailor learning experiences that accommodate
varying levels of language proficiency and cultural backgrounds (López, 2018; Meyer, Rose, & Gordon,
2014).
Furthermore, the integration of PBL and UDL frameworks in ESL classrooms aligns with contemporary
educational theories that emphasize learner-centered instruction and constructivist approaches. These

Furthermore, the integration of PBL and UDL frameworks in ESL classrooms aligns with contemporary
educational theories that emphasize learner-centered instruction and constructivist approaches. These
pág. 12688
theories argue that meaningful learning occurs when students are actively involved in the process of
constructing knowledge, rather than passively receiving information (Hmelo-Silver, 2004). In practice,
the combination of PBL and DUA facilitates a learning environment where students not only acquire
language skills but also develop a deeper understanding of cultural nuances and real-world applications
of their language abilities.
In addition to promoting academic skills, these methodologies have been shown to increase student
motivation and engagement, which are critical factors in successful language acquisition. Studies have
indicated that when students are given opportunities to work on authentic, relevant projects and multiple
avenues to express their learning, they exhibit higher levels of intrinsic motivation and commitment to
their studies (García, 2017; Hernández, 2019). This is particularly significant in ESL contexts, where
students often face additional challenges such as language anxiety and limited exposure to the target
language outside the classroom.
Given these advantages, this study explores the effectiveness of integrating PBL and the DUA
framework into ESL instruction. The research aims to provide empirical evidence on how these
innovative approaches can transform language learning environments by examining their impact on
student engagement, motivation, and language proficiency. The study also considers the challenges
associated with implementing these methodologies, such as the need for clear instructional guidelines
and adequate resource allocation, to offer comprehensive recommendations for educators.
In summary, integrating PBL and UDL represents a significant shift from traditional, teacher-centered
models to more dynamic, learner-centered approaches in ESL education. This study contributes to the
growing body of literature on innovative language teaching methods and offers practical insights into
how educators can harness the potential of these strategies to create more engaging, effective, and
inclusive learning environments.
Theoretical Framework (PBL)
Project-Based Learning is a student-centered instructional strategy that emphasizes solving real-world
problems through hands-on projects and collaborative inquiry. By engaging in authentic tasks, learners
are encouraged to apply their knowledge in meaningful contexts, thereby promoting deeper
understanding and retention of content. In the context of English language instruction, PBL enables

Project-Based Learning is a student-centered instructional strategy that emphasizes solving real-world
problems through hands-on projects and collaborative inquiry. By engaging in authentic tasks, learners
are encouraged to apply their knowledge in meaningful contexts, thereby promoting deeper
understanding and retention of content. In the context of English language instruction, PBL enables
pág. 12689
students to practice and refine their linguistic and communicative skills by working on projects that
simulate real-life scenarios—ranging from community-based initiatives to simulated business meetings
or creative storytelling. This active engagement helps to develop critical thinking, problem-solving, and
decision-making abilities, which are essential components of language proficiency (Thomas, 2000; Bell,
2010).
The method fosters an environment where learners are not passive recipients of information but active
participants in their educational journey. By collaborating in groups, students negotiate meaning,
articulate their ideas, and receive immediate feedback from both peers and instructors. This dynamic
interaction not only enhances linguistic fluency but also promotes socio-cultural learning, as students
are exposed to different perspectives and real-world communication challenges (Krajcik & Blumenfeld,
2006). Furthermore, PBL has been shown to stimulate intrinsic motivation and higher levels of
engagement, as learners see the relevance of their language skills to everyday life and future professional
endeavors. The iterative process of planning, executing, and reflecting on projects helps learners to
internalize complex linguistic concepts and apply them in novel situations, thereby bridging the gap
between theory and practice.
Universal Design for Learning (UDL):
The Universal Design for Learning framework is founded on the premise of providing equitable access
to learning by addressing the diverse needs of all students. UDL advocates for the creation of flexible
and inclusive instructional environments that offer multiple means of representation, engagement, and
expression. In practice, this means that educational materials and activities are designed from the outset
to accommodate a wide range of learning styles, cultural backgrounds, and abilities, ensuring that every
student can access and interact with the content in a manner that suits their individual needs (Wiggins
& McTighe, 2005; CAST, 2018).
In language teaching, the (UDL) framework can be particularly transformative. By presenting
information through various modalities—such as visual aids, auditory recordings, interactive digital
media, and hands-on activities—teachers can help students better grasp complex linguistic concepts.
Additionally, UDL encourages educators to employ flexible assessment methods that allow students to
demonstrate their learning in diverse ways, whether through written assignments, oral presentations,
students to practice and refine their linguistic and communicative skills by working on projects that
simulate real-life scenarios—ranging from community-based initiatives to simulated business meetings
or creative storytelling. This active engagement helps to develop critical thinking, problem-solving, and
decision-making abilities, which are essential components of language proficiency (Thomas, 2000; Bell,
2010).

pág. 12690
creative projects, or digital storytelling. This not only supports students with different learning
preferences but also enhances cognitive engagement by challenging them to process and apply
information in multiple contexts (Meyer, Rose, & Gordon, 2014).
Research indicates that implementing the UDL framework in language teaching can lead to significant
improvements in both cognitive engagement and linguistic proficiency. When students are provided
with choices in how they learn and express their knowledge, they are more likely to be motivated and
invested in their learning process. The integration of UDL principles with project-based approaches
further amplifies these benefits, as students are empowered to explore language in contexts that are
personally meaningful and relevant to their everyday experiences (López, 2018). Thus, the combined
use of PBL and UDL represents a holistic approach to language instruction that is both inclusive and
effective.
METHODOLOGY
This study employs a quasi-experimental design to rigorously evaluate the impact of PBL and the UDL
framework on English language acquisition among ESL students. The research design includes two
distinct groups: an experimental group that receives instruction based on PBL and UDL principles, and
a control group that follows traditional language instruction methods. This comparative design allows
for the examination of differences in language proficiency, motivation, and engagement attributable to
innovative instructional methods.
Participant Selection:
This study was conducted at Unidad Educativa Tabacundo, Ecuador, with participants aged between
13 and 18. 100 ESL students were selected using stratified random sampling to ensure a representative
distribution of proficiency levels, age groups, and backgrounds. Stratification helped to control for
potential confounding variables, ensuring that both the control and experimental groups were
comparable at the outset of the study. This sampling method also enhanced the generalizability of the
findings to a broader population of ESL learners.
Data Collection Instruments and Procedures:
The study utilized a multi-method approach to data collection, which included quantitative and
qualitative measures:
creative projects, or digital storytelling. This not only supports students with different learning
preferences but also enhances cognitive engagement by challenging them to process and apply
information in multiple contexts (Meyer, Rose, & Gordon, 2014).

qualitative measures:
pág. 12691
• Pre- and Post-Tests: Language proficiency was assessed through standardized tests
administered before and after the intervention. These tests measured various aspects of language
acquisition, including vocabulary, grammar, reading comprehension, and oral communication skills.
• Motivation and Engagement Surveys: Customized surveys were distributed to capture
students’ self-reported levels of motivation, engagement, and satisfaction with the instructional
methods. The surveys included both Likert-scale items and open-ended questions to gather in-depth
insights into the students’ experiences.
• Qualitative Observations: Classroom interactions were observed and recorded to provide
contextual data on the dynamics of group work, the implementation of PBL activities, and the integration
of UDL strategies. These observations were complemented by teacher interviews, which provided
additional perspectives on the effectiveness of the methodologies and the challenges encountered during
instruction.
• Data Triangulation: The study employed data triangulation by combining test scores, survey
responses, and observational data. This approach ensured a comprehensive evaluation of the
instructional methods, enabling the researcher to corroborate findings across different sources
(Hernández, 2019; Muñoz & Ramírez, 2020).
Data Analysis:
Quantitative data from the tests and surveys were analyzed using statistical methods to identify
significant differences between the control and experimental groups. Descriptive statistics provided an
overview of the central tendencies and variability in language proficiency and motivation scores, while
inferential statistics were used to assess the effectiveness of the intervention. Qualitative data were coded
and analyzed thematically, allowing for the identification of recurring patterns and insights related to
student engagement, collaboration, and the practical challenges of implementing PBL and UDL.
This comprehensive methodological framework ensured that the study captured both the measurable
outcomes of language learning and the nuanced experiences of students engaged in innovative, learner-
centered instructional approaches. The combination of rigorous quantitative analysis with rich
qualitative data provided a robust foundation for evaluating the impact of PBL and the UDL framework
on ESL education.

Preliminary findings from the study indicate that students exposed to Project-Based Learning (PBL) and
the Universal Design for Learning UDL framework exhibit markedly higher levels of engagement,
motivation, and linguistic competence compared to their peers in the control group who received
traditional language instruction. Quantitative analyses of pre-and post-test scores reveal that the
experimental group achieved statistically significant improvements in key areas of language acquisition,
including vocabulary acquisition, speaking fluency, and overall comprehension skills (García, 2017;

vocabulary assessments. Similarly, speaking fluency—measured through structured oral presentations
and interactive classroom discussions—demonstrated notable gains, with students exhibiting enhanced
pronunciation, intonation, and a higher frequency of spontaneous speech. These improvements in oral
communication skills are particularly significant given the emphasis of PBL on real-world language use
and collaborative tasks.
In addition to these measurable gains, qualitative observations during classroom sessions provided rich
insights into the dynamics of student engagement. Observers noted that learners in the experimental
group were more active in group discussions, demonstrated a greater willingness to take risks in using
English, and participated more enthusiastically in collaborative projects. These behaviors suggest that
the integration of PBL and UDL not only facilitates language learning but also cultivates a more
supportive and interactive learning environment.
Furthermore, motivation surveys administered throughout the study indicated that students exposed to
PBL and UDL reported higher levels of intrinsic motivation. Approximately 55% of the students in the
experimental group described themselves as “very motivated,” compared to only 35% in the control
group. This increased motivation is believed to stem from the relevance and authenticity of the tasks,
which allowed students to see the real-world applicability of their language skills.
The examination further showed that the overall comprehension skills of the experimental group
improved significantly. Students demonstrated a better ability to understand complex texts and engage
in critical thinking tasks related to language content. These improvements were corroborated by both
quantitative test results and qualitative feedback from both students and instructors, who observed that
learners were better able to connect new linguistic concepts with their existing knowledge and apply
them in varied contexts.
In summary, the results of this study provide compelling evidence that integrating PBL and UDL into
ESL instruction leads to enhanced language proficiency. The combination of improved vocabulary,
fluency, and comprehension, coupled with increased student motivation and engagement, underscores
the potential of these innovative educational approaches to transform language learning environments.
Future analyses will continue to explore these trends, with a focus on long-term retention and the
transferability of language skills beyond the classroom setting.

DISCUSSION
The discoveries of this study highlight the effectiveness of Project-Based Learning (PBL) and the
Universal Design for Learning (UDL) framework in facilitating English language acquisition. The
results indicate that students exposed to these methodologies demonstrate higher levels of engagement,
motivation, and overall linguistic competence. This section provides an in-depth discussion of the key
findings and their implications for second language acquisition (SLA).
One of the most significant findings is the distribution of English proficiency levels among the
participants. According to the survey results, a considerable portion of students (60%) reported an
intermediate level of English proficiency, while 25% identified as beginners, and only 15% considered
themselves advanced or proficient. This distribution suggests that most students are still in the process
of developing their language skills and require instructional strategies that promote engagement,
collaboration, and real-world application (Hmelo-Silver, 2004; Thomas, 2000). PBL and UDL offer a
structured yet flexible learning environment that can cater to diverse learning needs, ensuring that
students at all proficiency levels receive appropriate support and opportunities for improvement.
Regarding students' experience with PBL and the UDL framework, the data revealed that 70% had
previously participated in a PBL-based learning experience, while 30% had not. However, familiarity
with the UDL framework was lower, with only 40% of students reporting some level of familiarity,
while 60% had limited or no knowledge of the framework. This suggests that while PBL is somewhat
integrated into the curriculum, the UDL framework remains underutilized (Hernández, 2019; López,
2018). This underutilization could be attributed to a lack of teacher training in implementing inclusive
and differentiated learning strategies or a limited understanding of how to incorporate UDL principles
effectively within language instruction.
Inspiration levels were also assessed, with 55% of students reporting feeling very motivated when using
PBL and UDL, while 30% were somewhat motivated. A smaller percentage (15%) indicated low
motivation levels. These results support existing research, which suggests that PBL and student-centered
approaches increase engagement and self-efficacy in second language learning (García, 2017; Wiggins
& McTighe, 2005). The higher motivation levels can be attributed to the interactive nature of PBL,
which allows students to take ownership of their learning by engaging in meaningful projects that align

pág. 12704
with their interests. Additionally, the multiple means of representation, engagement, and expression
promoted by UDL ensure that students can access learning materials in a way that best suits their
learning styles.
Teamwork is another key factor in PBL and UDL methodologies. The survey results showed that 50%
of students felt very comfortable working in teams, while 35% were somewhat comfortable. However,
15% reported discomfort, indicating that while most students benefit from collaborative learning, some
may require additional support in team-based activities (Hmelo-Silver, 2004). The discomfort reported
by a minority of students may stem from difficulties in coordinating group tasks, communication
barriers, or varying levels of participation among team members. These challenges suggest that
instructors should provide clearer guidelines for group work, incorporate structured roles within teams,
and facilitate regular check-ins to ensure equitable participation.
In terms of challenges, students identified time management, difficulties in group coordination, and
occasional lack of clarity in project instructions as the primary obstacles. These findings are consistent
with prior research, which suggests that successful implementation of PBL requires structured guidance
and clear task distribution (Thomas, 2000). Time management remains a common challenge in project-
based learning environments, as students often struggle to allocate adequate time for research,
collaboration, and project execution. Educators can address this issue by implementing clear timelines,
breaking tasks into manageable steps, and providing scaffolding to support students in meeting
deadlines.
Conversely, the most cited benefits included increased engagement, improved critical thinking skills,
and greater opportunities to apply English in real-life contexts, reinforcing previous studies on the
effectiveness of authentic learning experiences in language acquisition (García, 2017; Hernández,
2019). The ability to use English in authentic, real-world situations helps students develop practical
language skills that extend beyond the classroom. The emphasis on critical thinking and problem-
solving in PBL also prepares students for real-world communication challenges, fostering a deeper
understanding of the language and its applications.
To boost the effectiveness of these methodologies, students suggested more structured guidance, clearer
instructions, and additional support materials to reinforce learning. Notably, 80% of students
with their interests. Additionally, the multiple means of representation, engagement, and expression
promoted by UDL ensure that students can access learning materials in a way that best suits their
learning styles.

To boost the effectiveness of these methodologies, students suggested more structured guidance, clearer
instructions, and additional support materials to reinforce learning. Notably, 80% of students
pág. 12705
recommended PBL and UDL to other English learners, indicating a high level of overall satisfaction.
These findings align with research advocating for scaffolded instruction and differentiated learning
pathways in second language acquisition (Wiggins & McTighe, 2005). Scaffolding strategies, such as
providing exemplars, using guided questioning techniques, and incorporating technology-based learning
tools, can further support students in navigating PBL and UDL-based instruction.
The broader implications of these findings suggest that while PBL and UDL have a positive impact on
English language learning, their implementation could be refined to better address time management,
clarity, and collaboration-related challenges. Educators should receive adequate professional
development on how to effectively integrate these approaches into their teaching practices. Additionally,
institutions should provide necessary resources, such as digital platforms, instructional materials, and
collaborative tools, to facilitate the implementation of PBL and UDL methodologies.
Future research could explore differentiated strategies to support students at varying proficiency levels
and ensure that both frameworks are effectively integrated into language instruction (López, 2018).
Investigating the long-term impact of PBL and UDL on language retention and academic achievement
could provide valuable insights into their sustainability as instructional approaches. Moreover,
comparative studies analyzing PBL and UDL in various cultural and linguistic contexts could contribute
to a deeper understanding of how these frameworks can be adapted to meet diverse educational needs.
The study's findings underscore the importance of implementing innovative and inclusive pedagogical
strategies to enhance English language acquisition. By incorporating PBL and UDL effectively,
educators can create dynamic and engaging learning environments that empower students to develop
their linguistic competencies while fostering collaboration, critical thinking, and real-world application.
CONCLUSION
This study underscores the transformative potential of Project-Based Learning (PBL) and the Universal
Design for Learning (UDL) in enhancing English language acquisition. Both methodologies
significantly boost student engagement, promote meaningful collaboration, and improve linguistic
proficiency, especially among intermediate learners. By focusing on real-world applications and
inclusive strategies, PBL and (UDL) create dynamic, student-centered environments that address
diverse learning needs and preferences (Joseph, 2025).

However, while PBL is widely recognized, the limited familiarity with (UDL) highlights the need for
greater integration into language curricula. This calls for comprehensive teacher training and the
development of accessible instructional resources to support all learners effectively. Challenges such as
time management, group dynamics, and project clarity emphasize the importance of structured guidance,
scaffolded activities, and differentiated learning paths to optimize outcomes. Educators are encouraged
to adopt PBL and (UDL) to foster more engaging and inclusive classrooms. Future research should
explore their long-term impact, adaptability across cultural contexts, and the role of digital tools in
enhancing implementation. Additionally, refining support mechanisms can address existing challenges
and improve instructional efficacy. The strong positive feedback from students and their high
recommendation rates affirms the value of these approaches in ESL instruction. By addressing current
gaps and advancing these frameworks, educators and researchers can significantly enhance language
learning experiences, driving greater academic success and language proficiency.
