Abstract.
Foreign‐language learners often struggle to move new lexical items from
short-term exposure to durable, retrievable knowledge. Cognitive research suggests that
visual–verbal integration, association density, and generative processing all facilitate lexical
retention, yet classroom practice still relies heavily on de-contextualised word lists and rote
repetition. The present study investigates the effectiveness of mind mapping as a vocabulary-
building technique in an English-as-a-foreign-language (EFL) context. Sixty intermediate
Uzbek university students were divided into experimental and control groups. Over ten weeks
the experimental group constructed handwritten and digital mind maps that connected target
words to semantic neighbours, collocations, images, and L1 equivalents, while the control
group used traditional notebook glossaries. The findings support dual-coding, generative
learning, and cognitive-load theories, suggesting that mind maps can be a cost-effective,
scalable tool for vocabulary expansion.

Vocabulary knowledge is widely recognised as the bedrock of communicative
competence, yet lexical growth remains one of the most intractable challenges for learners
and teachers alike. Research spanning decades (Nation, 2022; Schmitt, 2014) demonstrates
that learners require repeated, elaborated encounters with words across modalities before
durable lexical representations emerge. Traditional techniques—word lists, translation pairs,
and sentence gap-fills—often promote shallow processing and minimal semantic networking,
leading to forgetting curves that erase gains within weeks.
Mind mapping, popularised by Buzan and Buzan (1993), offers a visually structured
method for integrating new information into existing cognitive schemata. A mind map
radiates outward from a central concept, linking branches that represent sub-themes,
associations, images, and personal notes. This radial format ostensibly leverages dual-coding
(Paivio, 2008) and multimedia learning principles (Mayer, 2020), enabling simultaneous
activation of verbal and non-verbal channels while reducing extraneous cognitive load
(Sweller, Ayres & Kalyuga, 2011).
Empirical work linking mind maps to foreign-language vocabulary growth remains
limited and sometimes methodologically weak. Al-Jarf (2009) found significant receptive
gains in a web-based Saudi EFL cohort, whereas Liu and Ying (2019) reported mixed results
when mind maps were used only as a pre-reading strategy. Most studies employ short
interventions or rely solely on receptive post-tests, leaving questions about productive depth,
retention, and learner perceptions unanswered. Moreover, few investigations situate mind
mapping within a theoretical triangulation that unites cognitive-load theory, generative
learning, and input-enhancement frameworks (Krashen, 1985).
The present study addresses these gaps by examining whether systematic mind-map
creation fosters both receptive and productive vocabulary growth, by exploring learner
attitudes toward the technique, and by aligning findings with contemporary cognitive

theories. Three research questions guide the inquiry: (1) Does mind mapping produce greater
receptive-vocabulary gains than traditional note-taking? (2) Does it enhance productive
lexical use? (3) How do learners perceive the cognitive and motivational affordances of mind
mapping?
Participants were sixty second-year undergraduates (age 18–21, 38 females, 22 males)
enrolled in a compulsory English for Academic Purposes programme at Tashkent University
of Information Technologies. Entry-level proficiency was B1-minus on the CEFR, confirmed by
an institutional placement test. All participants had studied English for at least six years and
reported minimal prior exposure to mind-mapping techniques.
A quasi-experimental pre-test/post-test design compared an experimental group (n =
30) engaging in mind mapping with a control group (n = 30) employing standard vocabulary
notebooks. Classes met twice weekly (90 min) over a ten-week semester. Both groups
received identical instructional input—40 thematic readings covering science and technology
topics—delivered by the same instructor. The only variable was the note-making strategy
practised after each lesson.
Following each reading, the experimental group collaboratively compiled a list of ten to
twelve target words selected for salience, academic relevance, and frequency band (Nation’s
4K–8K). Students then drafted individual mind maps around each target, embedding
synonyms, antonyms, collocations, morphemic decompositions, contextual sentences, and,
where appropriate, mnemonically resonant images. The instructor modelled efficient
branching, colour coding, and minimal text. In weeks six to ten the group migrated to a free
digital tool (Coggle™) to encourage technological transferability.
The control group copied teacher-provided word lists into lined notebooks, wrote L1
translations, and composed one example sentence per word—common practice in the local
curriculum. Time on task for both conditions averaged fifteen minutes per session to control
for exposure.
Receptive lexical breadth was measured with version 2 of the Vocabulary Size Test
(VST) consisting of fourteen 10-item clusters. Productive depth was assessed with the open-
response Lex30 test. Internal reliability indices for the cohort were α = 0.91 (VST) and α =
0.87 (Lex30). Semi-structured interviews, conducted in Uzbek during week eleven with fifteen
volunteers from each group, elicited perceptions of strategy usefulness, cognitive effort, and
engagement.
Pre- and post-test scores were analysed using paired-samples t-tests within groups and
independent-samples t-tests across groups. Effect sizes (Cohen’s d) complemented p-values to
gauge practical significance. Interview transcripts underwent thematic coding using an
inductive approach, followed by frequency tallies of emergent categories.
Baseline comparisons showed no significant difference between groups in receptive or
productive scores (p > 0.45). After ten weeks, the experimental group’s mean VST score rose
from 3 210 to 3 722 items, a 16 % gain (t = 8.14; p < 0.001; d = 1.02). The control group
improved from 3 236 to 3 398 items, a 5 % gain (t = 2.21; p = 0.033; d = 0.29). Between-group
analysis of gain scores yielded t = 4.12 (p < 0.01), indicating a statistically robust advantage
for mind mapping.
Productive-knowledge outcomes mirrored the receptive pattern. The experimental
group increased its Lex30 mean from 13.4 to 15.9 unique lemmas, equating to a 19 % gain (t =

5.02; p < 0.001; d = 0.65), while the control group rose from 13.2 to 14.0 lemmas, a 6 % gain
that narrowly missed significance under Bonferroni adjustment (t = 1.98; p = 0.054).
Interview analysis revealed three dominant themes among mind-map users: heightened
metacognitive control, visual memory support, and intrinsic enjoyment. Students reported
that branching encouraged them to “see hidden relations,” prompted elaborative rehearsal,
and reduced anxiety about forgetting. Control-group learners described their method as
“simple but boring,” with several noting reluctance to revisit lists after initial completion.
From a theoretical standpoint, the results lend empirical weight to dual-coding theory.
Learners simultaneously encoded verbal definitions and spatial–visual nodes, generating
multiple retrieval cues. Generative-learning theory (Mayer, 2020) is likewise supported: the
act of building connections required semantic processing beyond orthographic copying.
Cognitive-load theory further explains the efficiency gains; mind maps externalised relational
information, freeing working-memory resources for deeper integration, a dynamic
corroborated by learners’ introspective reports of reduced mental clutter.
While the control group showed modest progress, their relatively shallow gains
epitomise the inherent ceiling of rote translation lists. The reluctance to revisit such notes
echoes previous observations that boredom undermines recycling frequency, thereby
impeding consolidation.
Mind mapping emerges as a promising, learner-friendly technique for vocabulary
expansion in foreign-language classrooms. By fostering associative networks, stimulating
generative processing, and alleviating cognitive load, it outperforms traditional list-based
approaches in both receptive and productive domains. Pedagogical adoption requires minimal
resources yet yields appreciable lexical dividends. Broader implementation and longitudinal
monitoring can further clarify its role within an integrated strategy repertoire for vocabulary
instruction.
