The main purposes of this study were to explore the convergent effect of the discrepancy of creative teaching role identity verification, and to analyze how the discrepancy influences on the change of role identity standard and behavior of creative teaching. Using longitudinal research design, the data collected combines all four waves of data for the study. The researchers run Latent Change Model (LCM) and Latent Autoregression Model (LAM) to test hypotheses. The results revealed that the discrepancy of creative teaching role identity verification: (1) showed a convergent effect over time, (2) had positive effects on the change of creative teaching role identity standard, and (3) it (T2) had a negative effect on the change of creative teaching behavior (T3-T2).
