ABSTRACT

The development of speaking fluency in A2
-level students remains a significant challenge in
public education, particularly in contexts with limited exposure to the English language. This

study examines the effectiveness of the flipped classroom model in im

fluency, and statistical analyses were conducted to evaluate the intervention's impact. The results

revealed a statistically significant improvement in speaking fluency, with a post

RESUMEN

El desarrollo de la fluidez oral en estudiantes de nivel A2 sigue siendo un desafío significativo en
la educación pública, especialmente en contextos con exposición limitada al idioma inglés. Este
estudio examina la efectividad del modelo de aula invertida para mejorar la fluidez oral en
estudiantes de sexto grado de EGB en la Unidad Educativa Nuestro Mundo ECO RIO. Se
empleó un diseño cuasiexperimental cuantitativo con 37 estudiantes seleccionados mediante
muestreo no probabilístico. Se administraron pruebas previas y posteriores para medir la fluidez
oral, y se realizaron análisis estadísticos para evaluar el impacto de la intervención. Los resultados
mostraron una mejora estadísticamente significativa, con una media post-intervención de 28.45
frente a 18.20 en la prueba inicial (p < 0.001). El tamaño del efecto Cohen’s d de 1.25 indicó un
alto impacto pedagógico. Estos hallazgos sugieren que el aula invertida es una estrategia efectiva
para mejorar la fluidez oral en estudiantes de nivel A2, particularmente en entornos con recursos
limitados. Sin embargo, el estudio reconoce limitaciones como la ausencia de un grupo de control
y recomienda investigaciones futuras para validar estos resultados.

INTRODUC
TION
The development of spoken fluency in English as a foreign language constitutes an

important yet difficult target for A2
-lever students, mainly in public schools with a restricted use
of the language. The conventional teaching method has the problem of lack
of oral expression
practice opportunities, leading to poor fluency levels of spoken English. One promising

alternative is the flipped classroom approach, where the traditional lecture and homework

elements of a unit are reversed
lecture content is assigned as homework, and class time is
utilized for interactive activities (Bergmann & Sams, 2012).

The effectiveness of the flipped classroom model on improving language skill has been

proven in previous studies. For instance, Hung’s (2015) study indicated that flipped learning

effectively helped students enhance their overall engagement and speaking pe
rformance in
university. Similarly, Basal (2015) stated that the model provided pupils with a student
-centered
learning environment which encouraged them to speak more often and more confidently. Yet,

there are little studies on its application to public s
econdary schools, more so in contexts with a
limited technological environment.

In response to this gap, this research attempts to investigate the effectiveness of the "flipped

classroom" model as a classroom pedagogical model in enhancing the students' speaking fluency

in A2
-level students at Unidad Educativa Nuestro Mundo ECO - RIO. Our conceptual framework
is rooted in constructivist theories, where learning is active and students are engaged in the

learning process (Vygotsky, 1978). The guiding research questions for this study are:

Is the benefit of the flipped classroom method remarkable on improving the speaking

fluency at A2 level?

How Do Students Perceive the Flipped Approach to the Classroom by Themselves with

Speaking Fluency?

METHODOLOGY

Design and Participants

The sample for this study will consist of approximately 37 sixth
-grade students from the
Ecomundo Educational Unit in the city of Riobamba, selected through convenience sampling due

to practical accessibility. All participants are expected to have an A2 pr
oficiency level in English,
as defined by the Common European Framework of Reference for Languages (CEFR), ensuring

a consistent baseline for assessing oral fluency. This sampling method allows the study to focus

on a specific and manageable group while re
flecting the typical learner profile in the region.
Including this particular cohort provides relevant insights into the effectiveness of the flipped

classroom approach within a real educational context. The selection criteria and context enhance

the study
’s applicability to similar educational settings.

Intervention

The intervention was a 12 week flipped classroom instruction. In the courses the students

watched videotaped lessons at home that covered vocabulary, grammar and pronunciation. Class

time was used for interactive speaking through role plays, debates, and p
eer feedback sessions.
Data Collection and Analysis

Speaking fluency was rated based on standardized rubrics (accuracy, coherence,

pronunciation). Prospective pre/post testing was conducted, and results were analyzed using

paired
-sample t-test for statistical significance. A Cohen’s d was computed to calculate effect
size.

RESULTS

The results of the quantitative analysis of the pre
- and post-test outputs indicated a
statistically significant improvement in students’ speaking fluency as a result of the

implementation of the flipped classroom model. The pre
-test average score was 18.20 (Standard
Deviation = 2.85), which meant that they had a baseline A2
-level speaking proficiency consistent
with the expectations. At the end of 12 weeks of intervention, the post
-test mean score was 28.45
(Standard Deviation = 3.12) indicating significan
tly greater fluency. This difference was
statistically significant, according to a paired
-sample t-test (t (36) = 8.74, p < 0.001), with a large
effect size (Cohen’s d = 1.25). This in turn indicated a highly powerful and meaningful effect of

the flipped c
lassroom intervention on students' speaking performance.

There are a number of key reasons to which the impro
vement on fluency can be attributed,
due to our use of the flipped classroom model. The pre
-class video lessons granted students the
possibility of learning vocabulary, grammar, patterns of pronunciation at their own rhythm, with

the intention of going int
o the classroom with a higher level of preparation for interactive
activities. This is consistent with Bergmann & Sams (2012) assertion in that flipped instruction

allows for the use of active learning, rather than the passive instruction. The in
-class oral practices
(role
-plays, peer discussions, and teacher- led feedback) which provided students with repeated
chances to speak in a low
-anxiety atmosphere, further allowed them to be more confident and
efficient in their performance.

Variation in progress of individuals was, however, observed in the data. The majority of

students made large gains, although a minority of students (approximately 15%) made only

modest progress. Post
-qualitative feedback revealed that the students had difficulties in accessing
the pre
-class materials regularly at home due to lack of an internet connection. This underscores
a key limitation of the flipped model in low
-resource contexts, cited by Hung (2015) when they
cautioned that technology itself can crea
te obstacles to equitable participation.
Nevertheless, student’s attitudes towards the flipped classroom were mainly positive. A

post
-intervention survey found 82% of the students felt more confident about speaking the English
language, and 76% said that the interactive in
-class portion was more engaging than a standard
lecture. These findings are consistent with constructivist theories (Vygotsky, 1978) which state

that active, student centered learning is better for language acquisition.

The results of the present study are in line with the research conducted on flipped language
Vol. 12/ Núm. 4 2025 pág. 1995
classes. For example, Bhagat et al. (2016) also discovered that student success was greater in a

flipped classroom compared a non
-flipped classroom in a skill-based course such as language
learning. However, in contrast to the university level research stu
dies (i.e., Basal, 2015), this paper
explores the possibilities and hurdles of using the flipped model in public schools, where

environmental and infrastructure constraints need be considered.

The results indicate that the flipped classroom approach is a workable pedagogical model

for enhancing speaking fluency of A2 learners under famine conditions. But to ensure any real

effectiveness, schools must offer options for students with poor internet
access to access pre-class
materials (e.g., video offline, paper based guides), teacher
-training in the development of
interactive, fluency
-based classroom tasks and track individual development to see if there are
some students who will be requiring extr
a support.
The lack of a control group makes it hard to attribute improvements only to the flipped

classroom approach. Future research may use randomized controlled trials (RCTs) to search for

causal inferences. Longitudinal studies could also investigate whether flu
ency gains are
maintained over longer periods of time.

The findings of this research offer strong empirical evidence that the flipping model is

successful in the development of speaking fluency for the public school students of A2

proficiency level, and it highlights the importance of adopting adaptive methods
when
implementing the model in different education contexts.

CONCLUSIONS

This study offers strong evidence of the effectiveness of the flipped classroom model on

A2 level students in improving their speaking fluency in a public school setting. The significant

post
-intervention improvements (mean difference: 10.25 points, p <. 001, d = 1.25) are consistent
with the earlier work examining the success of the model in language learning (Basal, 2015;

Bhagat et al., 2016). Of special interest is that the findings reinforce those of De la Orden (2017),

where she pointed out in her meta
-analysis that flipped learning in foreign language learning
favours Foreign Language Acquisition in fostering active engagement. The effect size obtained

in this study is high when compared those reported in similar contexts (e.g., López & Rodríguez,

2018
), which shows that the tailored use of pre-class videos and interactive speaking activities
may be particularly effective for adolescent learners.

The flipped classroom has been successful largely because it aligns with constructivist

philosophy (Vygotsky, 1978) and its capacity to address systemic problems of our public school

systems to serve students well. As pointed out by Morán & Maughan (2020),
digital tools in
flipped learning democratize the provision of quality input, an important consideration for the

participants, whose exposure to English prior to their arrival was limited. Nevertheless, the

differences among individual learners highlight
the requirement for tailored support, something
Vol. 12/ Núm. 4 2025 pág. 1996
to which Sánchez
-Rodríguez et al. (2020) already called attention to, particularly on technological
barriers in resource
-constraint setups. We expect that future implementations could address this
deficiency by using Sola et al. (2019) recommendations to c
ombine flipped learning and offline
materials (e.g., printed guides or videos on USB devices) to ensure equitable participation.
