Though NLP is a major learning component of artificial intelligence (AI) education, few educational programs have been researched about NLP education. Accordingly, the development direction of the NLP education program was set by analyzing the relevant literature, curriculum, and textbook contents, and the results of expert validity analysis were reviewed. According to the reviewed development direction, the 22nd session of education programs and materials was developed. As a result of expert validity analysis, the educational program’s content validity was assessed. The program was then augmented and updated by the open response. It is expected that the developed curriculum-based NLP education program will be used as data for realizing AI education in the school field.
