Abstract

This study empirically examined the factors influencing the continued use intention of ChatGPT among elementary school students in Incheon who participated in ChatGPT-based task activities at public libraries. Based on the Technology Acceptance Model (TAM), the study employed regression analysis to investigate how perceived ease of use, usefulness, and enjoyment affect continued use intention. Furthermore, the study incorporated innovativeness as a mediating variable, drawing on the Innovation Diffusion Theory (IDT), to analyze potential indirect effects within these relationships. The results revealed that ease of use did not significantly affect continued use intention, whereas usefulness and enjoyment had significant positive effects. Secondly, innovativeness demonstrated a significant mediating effect in the relationships between both perceived usefulness and perceived enjoyment and continued use intention. Specifically, the indirect effect of perceived usefulness via innovativeness was significant (B = 0.166, 95% CI [0.061, 0.325]), as was the indirect effect of perceived enjoyment (B = 0.305, 95% CI [0.081, 0.530]). These findings suggest that students with higher levels of self-perceived innovativeness are more likely to recognize the utility and enjoyment of new technologies or services, which in turn enhances their intention to continue using them.
