AI is reshaping how students learn languages in K–12 education by offering adaptive and personalized learning experiences that adjust to individual needs. Unlike traditional one-size-fits-all approaches, AI technology can allow for dynamic, real-world language practice that meets each student’s pace and personal interests. This shift is essential for building fluency and ensuring students fully engage in learning.
Language learning apps, in particular, are now pivotal in delivering these personalized experiences. By leveraging AI, many platforms offer learning paths that adjust based on a student’s progress, helping develop essential language skills, including vocabulary acquisition, grammar understanding and real-world conversational practice. However, a well-rounded approach is crucial for effective learning.
Learning through real-world communication
Traditional language education often emphasizes memorizing vocabulary and grammar rules, but Stephen Krashen’s Comprehensible Input theory highlights that students learn best when they engage with language in meaningful contexts. AI enables this by providing interactive scenarios where students can practice language use in real-life settings.
Some language learning apps offer extensive native-speaker content, exposing students to authentic language speaking. While this helps improve comprehension, more depth in conversation practice promotes full language integration. AI allows learners to engage in simulated interactions that challenge their speaking skills, adapting the difficulty level in real time based on the learner’s progress.
Emergentism and AI’s role in language learning
Scott Thornbury’s Emergentism theory emphasizes that language learning occurs through true, meaningful use rather than memorization — language “emerges” as learners engage in real conversations and practice rather than through isolated drills or grammar exercises.
AI-powered tools in the classroom can embody this principle by offering interactive experiences that blend vocabulary acquisition with real-world language practice. For instance, the Memrise app integrates vocabulary learning with opportunities for students to participate in realistic conversations. This allows learners to see how language structures naturally emerge through use, as Thornbury suggests, rather than just memorizing rules in isolation.
By balancing structured learning with these real-world interactions, AI-driven tools support a more holistic approach to language learning, where foundational knowledge and practical application coexist.
How adaptive learning supports fluency
Paul Nation’s Four Strands model emphasizes that effective language learning requires a balance between meaning-focused input (listening, reading), output (speaking, writing), language-focused learning (grammar, vocabulary) and fluency development. AI-based tools are particularly effective at maintaining this balance by dynamically adjusting lessons to focus on each student’s specific needs.
For instance, while some apps are known for their focus on vocabulary or grammar drills, a few are designed to adapt to a student’s strengths and weaknesses, providing opportunities for both vocabulary retention and meaningful conversation practice. This kind of tailored learning ensures that students memorize words and use them in complex, real-world contexts, reinforcing their fluency across all areas of language acquisition.
Active conversation for fluency development
AI helps learners move beyond passive learning to actively use the language in meaningful, dynamic contexts — an essential component of fluency development. Michael Long’s Interaction Hypothesis supports the idea that active conversation is critical for becoming fluent in a foreign language. AI offers a unique advantage by enabling students to practice realistic conversations in a low-pressure environment. Instead of relying solely on passive listening or memorization, students are encouraged to speak, edit their approach and receive real-time feedback.
Some AI models can create environments where learners can simulate spontaneous conversations, like asking for directions or purchasing in a foreign language. This type of immediate feedback helps learners adjust their use of language, improving their confidence.
Continuous, adaptive learning
Traditional lessons often follow a rigid, fixed structure, but AI allows for real-time adjustments, tailoring the content to each student’s proficiency and areas of need.
For instance, when a student has mastered a particular set of vocabulary or grammatical challenges, AI can seamlessly introduce more complex tasks. However, if a student struggles with certain concepts, the system can slow down, offer additional practice or reintroduce material in a new context to reinforce learning.
In K–12 classrooms, this adaptability ensures that every student works at an appropriate challenge level, preventing frustration while encouraging steady progress.
Apps, platforms and tools using AI to integrate structured learning with real-world conversational practice are particularly effective in developing foreign language fluency, aligning with linguistic theories such as Thornbury’s Emergentism and Krashen’s Comprehensible Input. As AI continues to evolve, its ability to provide meaningful, interactive and personalized learning experiences will play an increasingly central role in helping students learn.
