Research-informed design
The evidence behind Eluency’s learning mechanics.
What this page means
Eluency uses established learning principles as product-design inputs. The studies below help justify those mechanisms and identify useful design constraints.
What this page does not mean
None of these studies evaluated Eluency. Their results should not be presented as Eluency outcomes, guarantees, certifications, or proof that every feature produces the same effect.
Design principles
Research informs the learning loop—not just the visual style.
Mobile continuity
Assigned work remains available beyond the classroom.
Active retrieval
Students produce or recognize answers instead of only rereading.
Multiple modes
Writing, listening, choice, images, and context vary the retrieval demand.
Actionable feedback
Mistakes and follow-ups direct attention to what needs another attempt.
Focused motivation
Progress, XP, streaks, and goals support returning without replacing the curriculum.

Meta-analysisMobile-assisted vocabulary learning

Mobile-assisted vocabulary learning
Zhou, Y., & Zhou, M. (2026). A meta-analysis on mobile-assisted vocabulary learning: Do mobile applications help? ReCALL, 38(1), 75–93.
This meta-analysis synthesized 65 experimental and quasi-experimental studies of mobile-assisted vocabulary learning. It reported stronger effects for sustained use and out-of-class learning conditions.
How it informs Eluency
- Eluency makes teacher-authored vocabulary available on the mobile device students already carry.
- Assignments, resume support, goals, and notifications can help make repeated practice easier to continue outside class.
- The study supports the general mobile-learning mechanism; it did not test Eluency or prove that every Eluency workflow produces the same effect.
Quasi-experimentTeacher-provided lessons delivered to mobile phones

Teacher-provided lessons delivered to mobile phones
Thornton, P., & Houser, C. (2005). Using mobile phones in English education in Japan. Journal of Computer Assisted Learning, 21(3), 217–228.
The study compared short vocabulary learning materials delivered through mobile phones with web and paper conditions. It found learning and preference advantages for the mobile delivery used in that setting.
How it informs Eluency
- Eluency similarly allows teacher-selected content to continue on a student’s phone.
- Notifications and short activity rounds can reduce the friction between receiving an assignment and beginning it.
- Modern Eluency activities differ substantially from the technology and procedure used in this 2005 study, so the relationship is directional rather than exact.
Field studyVocabulary activities across mobile and computer platforms

Vocabulary activities across mobile and computer platforms
Stockwell, G. (2010). Using mobile phones for vocabulary activities: Examining the effect of platform. Language Learning & Technology, 14(2), 95–110.
Students completed vocabulary activities on mobile phones or computers while the platform recorded behaviour and performance. The work highlights both the viability of mobile practice and the importance of reducing mobile friction.
How it informs Eluency
- Eluency keeps lesson progress and results connected when a student moves between the app and browser.
- Responsive controls, clear activity instructions, resume support, and appropriately sized targets address common mobile usability barriers.
- Eluency exposes completion, attempts, scores, and learning signals to teachers; any claim about a specific metric should match what the current result screen displays.
Quasi-experimentCumulative testing and distributed retrieval
Nakata, T., Tada, S., McLean, S., & Kim, Y. A. (2021). Effects of distributed retrieval practice over a semester: Cumulative tests as a way to facilitate second language vocabulary learning. TESOL Quarterly, 55(1), 248–270.
Cumulative testing and distributed retrieval

Students assigned to cumulative quizzes encountered both recent and previously studied vocabulary. The study reported substantially higher receptive and productive gains than the non-cumulative condition.
How it informs Eluency
- Eluency tests, practice rounds, mistake review, and teacher follow-ups can support retrieval-based learning.
- Teachers can deliberately include earlier vocabulary when building later tests and follow-up work.
- Eluency does not currently claim an automatic cumulative-test scheduler that mixes old and new vocabulary on the teacher’s behalf.
Meta-analysisDigital game-based language learning

Digital game-based language learning
Dixon, D. H., Dixon, T., & Jordan, E. (2022). Second language (L2) gains through digital game-based language learning (DGBLL): A meta-analysis. Language Learning & Technology, 26(1), 1–25.
This meta-analysis found positive language-learning effects across digital game-based studies while emphasizing that design, context, and implementation influence the outcome.
How it informs Eluency
- XP, streaks, goals, progress, encouraging feedback, and celebrations can make returning feel rewarding.
- Eluency keeps those mechanics secondary to teacher-assigned vocabulary, questions, listening, and writing.
- Game elements are engagement supports, not evidence that Eluency itself has achieved the effect sizes in the meta-analysis.
Responsible interpretation
Research should improve decisions, not become marketing decoration.
Match the mechanism
Connect a claim to the actual activity being implemented, such as retrieval, feedback, or mobile access.
Keep the limitation visible
Different learners, teachers, languages, durations, and implementation choices can produce different outcomes.
Measure Eluency separately
Product-specific outcomes require Eluency-specific evaluation rather than borrowing another intervention’s effect size.
