The best methods for effectively learning a new language online

The online language learning market has become denser in recent years with the proliferation of applications, videoconferencing platforms, and AI-powered tutors. However, learning a new language online remains a journey fraught with dropouts: the majority of app users give up after a few weeks, according to a 2024 report from ACTFL. The question is not so much about choosing the right tool but understanding what, in the method, truly fosters progress.

What AI tutors change (and do not change) in language learning

Since 2023, tools like ChatGPT or Claude have entered the learners’ toolkit. An observational study published in 2024 in Computer Assisted Language Learning, involving 1,000 Chinese learners using ChatGPT as a tutor, highlighted a measurable gain in oral confidence and conversational fluency.

On the other hand, the same study shows that the effect on grammatical progression remains insignificant when the AI tutor is used alone, without a study plan or human feedback. The chatbot corrects occasionally, rephrases, and prompts conversation, but it does not structure progression over several weeks.

In practice, a learner who dialogues daily with an AI tutor will gain ease in formulating simple sentences. To acquire the grammatical mechanisms of a case or tone language, a structured course with human correction remains the foundation. Resources like apprendissimo.fr allow for combining these approaches by articulating guided courses and autonomous practice.

Daily consistency and vocabulary memorization

The longitudinal study from the University of Nottingham (2023), conducted on 600 users of Duolingo and Babbel, leads to a clear conclusion: real progress is correlated with a fixed daily time slot, not the chosen application. A learner who logs in every day at the same time, even for ten minutes, progresses more than another who accumulates long but irregular sessions.

This result aligns with what memory neuroscience describes under the term spaced repetition. The brain consolidates vocabulary and grammatical structures when it encounters them at increasing intervals, not when it ingests them in bulk.

Establishing a ritual rather than multiplying tools

The temptation is strong to download three applications, enroll in a videoconference course, and watch series in the original version, all in the same week. Field feedback varies on the ideal number of tools, but one point consistently emerges in testimonials from advanced learners: it is better to use a single tool every day than to mobilize an arsenal sporadically.

  • Choose a fixed time slot (morning before work, lunch break, commute) and stick to it for at least three weeks to create a habit.
  • Limit the session to a specific task: reviewing vocabulary, listening to a dialogue, writing a short text. Not all three at once.
  • Add a second tool (conversation with a tutor, series in the original version) only when the first ritual is stabilized.

Free public resources often absent from comparisons

Online comparisons focus on Duolingo, Babbel, Busuu, or Preply. They often overlook free and structured public offerings that cover several languages with solid educational support.

In Belgium, Brulingua (an initiative of Actiris) provides free access to courses in English, German, Dutch, and French. This type of program exists in several European countries, often linked to employment or continuing education organizations. The available data do not allow for a direct comparison of their effectiveness with that of paid applications, but their format (progressive pathways, grammar exercises, listening comprehension) is similar to what commercial platforms offer.

Identifying offerings based on your country and target language

  • Check the websites of public employment services (France Travail, Actiris, Forem) that regularly offer free access to language platforms.
  • Consult university MOOCs (edX, FUN-MOOC) that offer language courses with certification, sometimes free for auditing.
  • Do not overlook digital municipal libraries, which increasingly include subscriptions to online language services.

Listening comprehension and pronunciation: beyond classic exercises

Listening to podcasts or watching series in the original version is a recurring piece of advice. Its limitation is rarely mentioned: passive listening without an associated task yields few measurable results. Watching a series subtitled in one’s native language trains the ear to prosody but does not force the brain to decode meaning.

For listening comprehension to improve, active listening is required: re-listening to a short passage, attempting to transcribe it, checking, then re-listening. The shadowing technique (repeating aloud immediately after the native speaker) engages comprehension, pronunciation, and working memory.

The underestimated role of written production

Writing a few sentences each day in the target language (a journal, a summary of the day, a message to a pen pal) activates different memory circuits than those engaged by reading or listening. This production work forces one to search for the right word, structure a sentence, and identify one’s own grammatical gaps.

Combining active listening and daily written production, even briefly, covers the four skills (listening comprehension, reading comprehension, oral expression via shadowing, written expression). It is this combination, more than the choice of an application, that distinguishes learners who progress from those who stagnate after the beginner level.

The tool matters less than how it is used. A fixed time slot, a specific task per session, regular human feedback on grammar and pronunciation: these three elements remain the foundation of online language learning that transcends the initial weeks of enthusiasm.
