AI in Language Learning: The Promise and Pitfalls

Artificial intelligence (AI) is increasingly becoming a valuable tool in language learning, providing new ways to support learners and educators alike. From beginners to advanced students and from teachers to content creators, AI has the potential to revolutionize how language content is created, delivered and learned.

AI technology has advanced rapidly over the last two years, with the more well-known tools like OpenAI’s GPT models often leading the way. Released in May of this year, GPT-4o has significantly enhanced the quality and reliability of AI-driven interactions and included multimodal ways of working with AI, allowing multi-media inputs as well as outputs from what was originally a text-only format. These improvements in accuracy, natural conversation flow and the ability to process multimedia inputs make it an increasingly viable option for educational settings. They present clear opportunities to enhance language learning experiences but also come with certain risks that must be considered.

Key Advantages of AI for Learners

Safe Space for Iterative Practice: AI-powered tools offer learners a judgment-free environment where they can practice language skills—speaking, listening, or writing—without fear of embarrassment. Learners can receive instant feedback and corrections, allowing them to experiment, make mistakes and improve incrementally. Best of all they can repeat their practice session on important topics again and again, getting a different but still realistic set of responses each time.

Personalized Tracking and Error-Pattern Recognition: For many years, AI systems have been able to analyze common mistakes or areas of difficulty, tracking a learner’s progress over time. Generative AI tools like Open AI’s GPT models now also allow for targeted interventions and personalized guidance based on these areas of opportunity, helping learners improve in the topics where they struggle the most.

Diverse Contexts and Cultural Settings: AI can expose learners to a wide variety of conversational settings, registers and cultural contexts. This breadth of exposure enhances their ability to adapt their language use to different situations, which is crucial for real-world language fluency. For learners looking for general fluency, this variety provides a broadly neutral global variant of the language, while learners preparing to travel to a specific region of the world are able to narrow the focus down to get regionally specific variants of their target language.

Complex Scenario-Based Interactions: AI can simulate detailed, scenario-based conversations that cater to highly-specific needs—whether it’s role-playing professional interviews, troubleshooting mechanical failure in an engine, or navigating a medical appointment. This provides opportunities for learners to practice language in nuanced, goal-specific situations.

Risks for Learners

Loss of Cultural Context and Nuance: While AI can generate grammatically correct language, it often misses the subtle cultural and contextual nuances that are crucial to truly mastering a language. Idioms, humor and culturally specific phrases may not be accurately conveyed or understood.

Limited Ability to Adjust Language Complexity: Many AI models struggle to simplify or grade language for beginner learners out of the box - most AI language learning products will have lots of prompting behind the scenes to keep the level appropriate and even then there’s a high likelihood of either overwhelming or oversimplified materials, making it harder for learners to engage effectively with content.

Missing “The Fear” of Real-Life Situations: One key aspect of language learning is overcoming the anxiety or “fear” of speaking with others in real-life situations. AI simulations are helpful, but they cannot fully replicate the pressure that comes with real-time interactions with other human speakers (judgment and all), which is critical for building confidence.

Key Advantages of AI for Educators

Efficient Text Generation: AI can quickly generate large amounts of text, especially for long or repetitive materials. This allows content creators to produce drafts for lessons or activities that can then be curated and fine-tuned to suit specific educational goals.

Drafting Specialized Syllabi or Course Structures: For complex or niche language topics, AI can help educators create a basic syllabus or course structure. This provides a valuable starting point that teachers can build upon to meet the specialized needs of their students.

Extracting Key Points for Review Materials: AI can analyze course materials and extract the main points or summaries, making it easier to create review sheets or quizzes for learners. This reduces time spent combing through large amounts of text to create concise study aids.

Avoiding Authorship Bias: While there is bias risk in the training data behind these language models, it’s undeniable that content authors also bring their own experience into their work. Using AI can help content creators step outside their own experiences and avoid unconscious bias in the materials they produce. This ensures a broader range of perspectives and topic choices, enhancing the diversity and broader appeal of the educational content.

Risks for Educators

Generic Tone and Creative Limitations: One of the major drawbacks of AI-generated content is its often generic tone of voice. AI-generated materials may lack the creative spark that makes educational content engaging and unique, requiring significant post-editing to give it personality.

Risk of Copyright Infringement: AI tools may inadvertently produce content that closely mirrors existing texts or materials, leading to potential copyright issues. This can be particularly problematic when publishing or distributing educational content at scale.

Inconsistent Quality Without Expert Review: AI can generate errors or inconsistencies in the content it produces, especially when it comes to complex grammar rules or specific cultural contexts. Subject-matter experts must carefully review and post-edit AI-generated materials to ensure accuracy and appropriateness.

The Role of Human Instructors in AI-assisted Learning

As AI continues to improve, the role of human instructors remains irreplaceable in certain key areas. AI can support and accelerate learning, but it cannot replicate the depth of cultural understanding, emotional connection, or nuanced teaching that a human can provide. Teachers act as "humans in the loop," guiding learners, curating content and ensuring that the materials generated by AI are accurate, culturally appropriate and engaging.

In the future, AI will undoubtedly become more sophisticated, but the need for human intervention will persist. Human educators will play a critical role in mitigating the risks associated with AI use, ensuring that it remains a powerful tool for language learning rather than a crutch. With AI and human expertise combined, language learners can benefit from a more flexible, efficient and personalized learning experience.
