Abstract: The effect of teaching practice of innovative thinking training on college students' innovative thinking ability was evaluated by EEG signal. Forty students were recruited as subjects and two tasks of unconventional use and word association were designed. Each task was divided into converging thinking and divergent thinking. The creativity generated under the two thinking conditions of each task was evaluated by combining the behavioral data of creativity scoring with the EEG data obtained from the analysis of EEG signals. The behavioral data of creativity score showed that under the divergent thinking condition of non-routine use task, the creativity score of the subjects after training was significantly higher than that before training (P<0.05), under the condition of divergent thinking in the word association task, the creative score of the subjects after training was significantly different from that before training(P<0.01); EEG data showed that the synchronization of α wave in frontal lobe was significantly different in the divergent thinking condition of the two tasks after training (P<0.01). The significant increase in creativity score and the enhanced synchronization of α wave in frontal lobe under divergent thinking condition both suggest that EEG signals can be used as away to quantify creative thinking. Therefore, the influence of teaching practice reform on college students' innovative thinking can be quantitatively evaluated by using EEG signal analysis method, which provides a new idea for the evaluation of teaching reform effect in the future.
