This study aimed to examine the effectiveness of the Havruta learning method using ChatGPT to improve the teaching efficacy of pre-service early childhood teachers. The effects of the Havruta teaching method in classes using ChatGPT on improving teaching efficacy were analyzed in a group of pre-service early childhood teachers to explore the direction of teaching and learning to improve the future educational capabilities required of prospective teachers. The participants were sophomores enrolled in a “Curriculum for Early Childhood Education” course at a university in Korea (Gyeonggi Province). During the 15-week of early childhood curriculum classes course, Havruta classes using ChatGPT were conducted for 12 weeks, excluding midterm and final exams. A paired-sample t-test was performed to verify the effectiveness of enhancing pre-service early childhood teachers’ teaching efficacy. The analysis showed that the Havruta learning method using ChatGPT positively affected both AI teaching efficacy and creative teaching efficacy for pre-service early childhood teachers. The findings verify that Havruta classes using ChatGPT are meaningful teaching and learning methods for pre-service early childhood teachers as future educators.
