Abstract:
English for Specific Purposes (ESP) has progressed from a narrowly defined branch of applied linguistics
into a cornerstone of professional preparation in non-Anglophone contexts. Although its contribution to subject-
related language proficiency is well documented, the ways in which ESP catalyses broader professional
competence remain under-researched. The present mixed-method study investigates the impact of an integrated
ESP programme on engineering undergraduates at three Central Asian universities. Quantitative data, obtained
from a pre- and post-course Professional Competence Self-Assessment Scale (n = 186) and performance-based
tasks, were complemented by qualitative evidence from classroom observations, semi-structured interviews, and
corpus analysis of student artefacts. Results demonstrate statistically significant gains across cognitive, social, and
affective dimensions of competence, with the largest improvement linked to intercultural teamwork and
reflective problem-solving. Qualitative findings reveal that authenticity of tasks, iterative genre practice, and
dialogic feedback were key drivers of change. The article argues that ESP functions as a boundary object
connecting disciplinary knowledge, language expertise, and workplace practice, thereby fostering employability
and lifelong learning dispositions. Policy implications for curriculum design, accreditation standards, and faculty
development are discussed.

Introduction:
Globalised knowledge economies have
reshaped the profile of language education, shifting
attention from generic communicative ability to
domain-specific discourse competence. Employers
increasingly expect graduates not only to manipulate
specialist lexis but also to collaborate across cultures,
reason ethically, and solve problems creatively. Early
ESP scholarship conceptualised language learning as a
response to immediate pragmatic needs (Hutchinson &
Waters, 1987), yet subsequent research often
measured success through narrow linguistic proxies
such as vocabulary size or test scores (Belcher, 2006).
Recent empirical work linking ESP with holistic
competence remains sparse and fragmented.
Engineering offers an instructive testbed because the
profession relies on multimodal genres
—
drawings,
specifications, feasibility studies, and incident logs
—
that operate under stringent regulatory and ethical
constraints. In Central Asia, many engineering
programmes teach English in isolated foundation
courses, divorced from disciplinary content, resulting in
low transfer to professional tasks. Aligning ESP more
closely with core engineering curricula and with
international
accreditation
frameworks
could,
therefore, enhance both linguistic and professional
outcomes. The present study addresses this agenda by
examining whether a redesigned, genre-based ESP
course improves students’ self
-perceived competence
and observable performance in authentic engineering
genres.
The investigation adopted a convergent-parallel mixed-
methods design that permitted the simultaneous
collection and mutual corroboration of quantitative
and qualitative evidence, thereby counteracting the

typical inferential threats that arise when language-
learning outcomes are examined in isolation from the
professional practices they purport to serve. Three
public universities with engineering programmes
accredited, or in candidacy for accreditation, under
EUR-ACE participated in the study; institutional
selection was predicated on curricular comparability
and a shared commitment to outcomes-based
education. The final sample comprised 186 second-
year undergraduates (Mage = 19.4; SD = 1.2) who had
completed a minimum of 600 contact hours of general
English and whose entry proficiency ranged from B1+
to B2 on the CEFR, as verified by the Oxford Placement
Test (M = 64.3; SD = 7.6).
Quantitative strand. To capture multi-faceted
development, the Professional Competence Self-
Assessment Scale (PCSAS) was adapted from the
Tuning Engineering Profile, translated into Uzbek and
Russian, and subjected to back-translation to
guarantee semantic equivalence. Exploratory factor
analysis (principal-axis factoring with oblimin rotation)
on pilot data (n = 72) yielded a three-factor structure
—
cognitive, social, affective
—
that explained 68 % of the
variance (KMO = 0.87; Bartlett’s χ² = 1764.5, p < 0.001).
Cronbach’s α after revision exceeded 0.85 for every
sub-scale. Baseline measurements were collected in
Week 1 and repeated after thirteen instructional
weeks; missing data were handled with full-
information maximum likelihood. Complementing self-
reports, two authentic performance assessments were
embedded: (i) a 1 500-word feasibility report governed
by the ASTM E2691 standard and (ii) a ten-minute oral
design-review briefing modelled on IEEE 830-2018
guidelines. Performances were blind-rated by two ESP
specialists and one practising engineer using a four-
dimension analytic rubric. Inter-rater reliability,
calculated through weighted Cohen’s κ, reached 0.82
for the written task and 0.79 for the oral task. Paired-
sample t-tests, followed by ANCOVA with initial
proficiency as covariate, established the statistical
significance
of observed gains (α = 0.05).
In parallel, a purposive sample of twelve intact classes
(four per institution) underwent non-participant
observation using a low-inference protocol focusing on
task authenticity, discourse moves, and metacognitive
episodes. Field notes, triangulated with 38 h of audio-
video recordings, were coded inductively in NVivo 14;
intercoder agreement reached 87 % after two rounds
of
reconciliation.
Twenty-four
semi-structured
interviews with students and six with ESP lecturers
elicited insider perspectives on competence transfer,
emotional engagement, and perceived barriers.
Interview guides were piloted for clarity and cultural
appropriateness;
member
checks
ensured
representational accuracy. Student artefacts
—
drafts,
peer-feedback logs, and reflective journals
—
were
subjected to a corpus-based analysis in AntConc 4.2.
Frequency lists and key-key-word comparisons against
a 3.2-million-word reference corpus of professional
engineering texts illuminated lexico-grammatical shifts.
Integration procedures and ethical safeguards.
Following a convergent design logic, quantitative and
qualitative
data
sets
were
merged
during
interpretation
through
narrative
weaving.
Convergences
strengthened
inferential
validity,
whereas divergences prompted re-examination of
codebooks and statistical models. Ethics approval was
granted by the lead university’s Research Ethics
Committee (protocol № 25
-04-2025). Written
informed consent, assuring anonymity and the right to
withdraw without penalty, was obtained from all
participants; pseudonyms replaced real names in field
notes and transcripts. Data were stored on encrypted
drives compliant with ISO/IEC 27001.
Survey data revealed significant gains across all
competence
dimensions.
Social
competence,
encompassing teamwork, conflict resolution, and
intercultural communication, rose by 18.4 percentage
points (p < 0.001). Cognitive competence, defined as
the ability to access and apply disciplinary knowledge
through English, increased by 14.2 percentage points (p
< 0.001). Affective competence, associated with
professional confidence and self-regulation, improved
by 12.7 percentage points (p < 0.01).
Performance-based evidence supported these self-
reports. Corpus analysis of 150 000 words of student
writing showed a twenty-seven per cent increase in
domain-specific noun phrases and a parallel decline in
vague language. Recommendation sections in
feasibility studies began to embed cost
–

rationales and regulatory citations, features scarcely
present in baseline drafts. Oral briefings displayed
tighter multimodal coherence, with slide content,
gestural emphasis, and vocal intonation synchronised
to match engineering rhetoric.
Observations documented a shift from teacher-
dominated exchanges toward peer-mediated problem
solving. By the tenth session, students negotiated
design disagreements almost entirely in English,
signalling
functional
communicative
autonomy.
Interviewees attributed progress to the authenticity of
tasks, iterative genre practice, and dialogic feedback
that linked linguistic form to engineering values such as
safety, efficiency, and sustainability.
Theoretical framing for these findings draws on genre
theory and community-of-practice perspectives that
view competence as enculturation into disciplinary

epistemologies.
Professional
communication
is
governed by recurrent rhetorical moves that convey
social purpose and power relations. Laboratory reports,
feasibility studies, and incident logs each encode
distinct obligations toward evidence, risk calculation,
and accountability. Iterative engagement with these
genres allows learners to internalise not only linguistic
forms but also the socio-cognitive processes that
cultivate professional identity.
Methodological rigour was enhanced by statistical
control of prior proficiency and triangulation of
multiple evidence streams. Reliability coefficients
above 0.83 and high inter-rater agreement strengthen
the validity of the quantitative claims, while qualitative
patterns provide rich explanatory insight.
Analysis of artefacts revealed that explicit genre
instruction and corpus-informed materials facilitate
lexical density and rhetorical precision. Students
learned to integrate quantitative data, regulatory
requirements, and visual design in ways that mirror
professional
engineering
practice,
thereby
substantiating claims that ESP can mediate complex
knowledge production (Lee & Park, 2024; Smirnova &
Petrova, 2022).
Policy
implications
are
far-reaching.
Where
accreditation frameworks treat ESP as an elective,
contact hours are limited and integration with
disciplinary
content
remains
superficial.
The
demonstrable gains observed here suggest that making
ESP a mandatory, credit-bearing component could yield
multiplicative returns on employability and innovation.
Alignment with standards such as EUR-ACE would
render language competence visible in credentialling
and strengthen the symbiosis between linguistic
mastery and technical expertise.
Finally, the study contributes to the discourse on
decolonising language education by foregrounding
contextual adaptability over native-speaker norms.
Authentic materials drawn from local engineering
projects and the encouragement of code-meshing
practices acknowledge multilingual realities. Such
pluralistic orientations reconfigure ESP as a
collaborative arena where English operates alongside,
not above, other repertoires, positioning competence
as negotiated and culturally responsive rather than
imposed from metropolitan centres.
The present study advances the argument that English
for Specific Purposes, when conceived as an epistemic
bridge rather than a language appendage, can
measurably elevate the professional competence of
engineering undergraduates. Statistical evidence
demonstrated large effect sizes across cognitive, social,
and affective domains, even after controlling for prior
English proficiency, while qualitative findings unpacked
the
classroom
mechanisms
—
authentic
genre
simulation, iterative feedback loops, and dialogic
mediation
—
that undergirded those gains. Crucially,
competence growth manifested not only in the
mastery of specialised lexis but also in the adoption of
disciplinary reasoning patterns and professional ethics,
suggesting that ESP served as a boundary object
through which students rehearsed the communicative
obligations of their future community of practice.
Several implications follow. First, curriculum designers
should abandon the siloed arrangement that relegates
ESP to preparatory semesters; embedding genre-based
ESP modules within technical courses can harness the
cognitive apprenticeship already inherent in laboratory
work and capstone design projects. Second,
accreditation bodies such as EUR-ACE and ABET could
strengthen the visibility of language-mediated
competence by aligning assessment descriptors with
ESP learning outcomes, thereby deterring tokenistic
implementation. Third, faculty development must
embrace co-teaching models where language
specialists and engineering lecturers co-design
assignments, share assessment rubrics, and jointly
curate corpora of local professional texts to ensure
cultural relevance.
Notwithstanding its contributions, the study is limited
by its reliance on self-reported competence and a
semester-length intervention. Longitudinal tracking of
graduates would clarify the durability of gains and their
translation into workplace performance indicators such
as project-documentation quality or client-interaction
effectiveness. Replication across disciplines with
distinct communicative ecologies
—
medicine, finance,
environmental
science
—
would
refine
the
generalisability of the boundary-object claim. Future
research might also explore how digital genres (e.g.,
GitHub issues, agile stand-ups) reshape ESP pedagogy
and professional identity formation.
In sum, ESP, strategically integrated and empirically
monitored, emerges as a potent catalyst for the holistic
professionalisation of non-Anglophone engineers,
equipping them with the linguistic, cognitive, and
ethical tools required to navigate
—
and to reshape
—
the transnational knowledge economies they are
poised to join.
