Chung-Ang University(CAU) Proves Educational Effectiveness of AI-Based Language Learning Platform

Are artificial intelligence (AI)-based education platforms, which are popular in the education field nowadays, really effective? Researchers at Chung-Ang University (CAU, President Park Sang-gue) answers this question.

CAU announced that a joint study conducted by Professor Lee Jangho of the Department of English Education and Professor Lee Hansol of Korea Military Academy came up with statistical proof of the educational effectiveness of the AI-based language learning platform. The research results were published in Volume 28, Issue 2 of “Language Learning & Technology,” the world’s top academic journal in the field of educational technology, with an Impact Factor (IF) of 5.20.

AI technology is being aggressively introduced into the field of education. Various forms and types of learning platforms have been developed and are being actively used in a wide range of fields, including teaching, learning, and educational administration. This is because there are expectations that personalized classes and learning, which had realistic limitations in traditional education methods and environments, will be provided more easily through AI algorithms. However, there has been a lack of detailed and systematic experimental research on whether these AI-based learning platforms are truly effective as educational tools.

Professor Lee’s research team analyzed data from over 8,300 learners using meta-analysis techniques based on a total of 61 empirical studies using an AI-based language learning platform. Results showed that the AI-based personalized language learning platform has statistically significant educational effectiveness in improving learners’ language skills.

For a more accurate analysis, the researchers statistically analyzed various differences, such as the age of the learners, the context of language learning, and the type of AI algorithm, but the results were not different. The study also revealed that the educational effectiveness of the AI ​​platform is effective when compared to traditional educational methods and environments.

The research team of Professors Lee Jangho and Lee Hansol has been conducting continuous research on the introduction and use of various technologies in the education field. They examined the use of the latest scientific technologies in language education, such as interactive chatbots such as ChatGPT as well as social robots that communicate with people, and jointly published over 20 research papers in top SSCI-level academic journals in relevant fields.

Professor Lee Jangho said, “We proved that personalized language learning, which has been difficult to implement realistically, can be effectively provided to diverse learners through an AI-based platform. It will be an effective method for learners who have difficulty accessing the appropriate educational environment, such as when there are too many students per teacher or when there are not enough teachers in the target language.” He also expressed that this research result should not lead to an expanded interpretation to the extent that AI can replace teachers.
