This research was jointly conducted by Professor Lee and Hansol Lee from the Korea Military Academy, and was published in the world’s top journal in the field of educational technology, Language Learning & Technology. The research team performed a meta-analysis on data from over 8,300 learners based on a total of 61 empirical studies utilizing AI-based language learning platforms. As a result, they verified that AI-based personalized language learning platforms have statistically significant educational effectiveness in improving learners’ language abilities.

Professor Lee stated, "We confirmed that personalized language learning, which has been difficult to implement practically, can be effectively provided to diverse learners through AI-based platforms. This will be an effective method for learners who have difficulty accessing appropriate educational environments, such as when the number of students per teacher is too high or when there is a shortage of teachers for the target language."
