This study evaluates how three AI models—ChatGPT, DeepSeek, and Clova X—detect and respond to gender-biased expressions in Korean. Clova X exhibited the highest accuracy in identifying discriminatory language, followed by ChatGPT, while DeepSeek performed the poorest. While terms like “kimchi girl” and “doenjang girl” were correctly recognized, phrases such as “female doctor” and “maiden work” were often misinterpreted. ChatGPT and DeepSeek occasionally provided inaccurate definitions, raising concerns about misinformation. Interestingly, DeepSeek performed best when interpreting sexist proverbs, although the overall differences across models were minor. All three models generally succeeded in recognizing biased expressions in conversational contexts, but DeepSeek struggled with non-standard sentence formats, leading to delays or missing responses. These results reveal current limitations in generative AI’s ability to process culturally specific and nuanced language. This study emphasized the need to incorporate more diverse Korean language data and up-to-date linguistic research in AI training. As generative AI tools become more integrated into everyday communication, improving their ability to detect and respond to gender biases is crucial for fostering fair and responsible language technologies.

This study outlines the language and gender studies in Korea over the past 30 years and derives some prospect of the future research. Following the epitome of the beginning and development of the studies in the framework of modern sociolinguistics, this article reviews the relevant studies on both Korean and foreign languages. The review shows that the works on this topic can be broadly classified into three main research areas; language variation, utterable genderlect and objective genderlect. Though having entered upon this research area two decades later than those in Amercian and European countries, Korean sociolinguists have produced significant results, especially in the gender-specific utterances in Korean. Works on other languages have been also carried out, often with applied linguistic purposes of cross-linguistic/cultural analysis, foreign language education, translation as well as consciousness raising of gender issues. Emphasizing the need for interdisciplinary approaches both in perspectives and research methods of the future studies, this article expects continuation of variation studies for completing the description of ‘language variation and change’, sociolinguistic efforts and movement against the gender bias and discrimination, and analysis of various types of communication in cyber space. It is also pointed out that language use of sexual minorities is one of the most untapped and subtle sociolinguistic topics in Korea.

It is generally believed that teachers are important both to student learning and achievement. Apart from teacher qualification and experience, some studies have shown that teacher gender may relate significantly to student achievement. The purpose of the study was to find out the following- (a) Does teacher gender significantly influence student academic achievement in English Language Arts at the junior secondary school level? (b). Does teacher gender significantly influence student academic achievement in Mathematics at the junior secondary school level? (c) Does teacher gender significantly influence student academic achievement in Biology at the junior secondary school level? Data was obtained from 570 students in seven junior secondary school students in South-East area of Nigeria. An analysis of data showed the following- In the English Language Arts area, and at the junior secondary school level, female students performed significantly higher than male students under a female teacher and male students performed better (but not statistically significant) under male teachers. In the area of Mathematics, female students performed significantly higher under male teachers. Based on the findings, recommendations were made on improving the teaching of English Language Arts, Mathematics and Integrated Science in Nigerian junior secondary schools.
