The Translation Debate
Many ESL training programs teach an 'English only' philosophy: ban the L1, force immersion, and fluency will follow. But what does the research actually say?
Tati, Ejus, and Askar (2024) found that both ESL teachers and learners view translation as an essential pedagogical tool — especially for lower-proficiency students who need it to comprehend complex syntax and conserve instructional time.
The Evidence
Pappamihiel, Ghimire, and Bellas (2026) surveyed 88 K-12 teachers and found that 81.8% utilize translation practices in their classrooms. Common methods include translation applications (89.6%), peer translation (72.2%), and native language texts.
But here's the critical distinction: ESL specialists reported higher confidence and perceived effectiveness than content teachers (confidence M=3.69 vs. 3.18; effectiveness M=3.76 vs. 3.29). The difference? Second language acquisition training.
Educational leaders in the study distinguished between productive translation (temporary scaffolding toward English independence) and counterproductive translation (wholesale content translation that creates dependency). 11.6% of observed practices fell into the counterproductive category.
As the researchers concluded: translation is a scaffold, not a crutch. Use it strategically and phase it out as proficiency develops.

The Scaffold Framework
Use translation when:
- Introducing complex concepts at A1-A2 (basic explanations in L1, then practice in English)
- Checking comprehension of key vocabulary (quick L1 confirmation, then back to English)
- Building confidence with anxious beginners

- Checking comprehension of key vocabulary (quick L1 confirmation, then back to English)
- Building confidence with anxious beginners
Phase out translation when:
- Students can paraphrase in English (even imperfectly)
- Students have reached B1+
- Students rely on translation for EVERY new word instead of using context clues

DrillKit approach: Generate exercises in English-only. If students need L1 support for vocabulary, provide a bilingual glossary alongside the worksheet. The exercises themselves remain in English — pushing productive use of the target language.
Frequently Asked Questions
Is English-only better for immersion?
add
For B1+ students in English-speaking environments, often yes. For A1-A2 students learning online or in their home country, strategic L1 support accelerates early comprehension without harming long-term outcomes.
How do I know when translation becomes a crutch?
add
Watch for signs: students translating every word instead of guessing from context, refusing to attempt reading without a dictionary, or asking for L1 explanations of structures they've practiced 10+ times.
