생명 현상의 공통성 지식 생성과 적용에서 나타나는 예비 교사의 뇌 활성화 양상

The purpose of this study was to analyze the pre-service biology teachers` brain activation patterns during the generation and application of commonness knowledge on biological phenomena. Sixteen right-handed healthy pre-service biology teachers volunteered to be participants in the present study. Stimuli within the commonness generation and application tasks were presented to subjects with a mixed design for the fMRI-scanning. The BOLD signals of the participants` brain were measured by 3.0T fMRI system and data were analyzed using SPM2. According to the results, the generation of commonness knowledge was found to have independent brain network different from the application of it. In the generating process of commonness knowledge, the significant activations were mainly observed in the left hippocampus, which is presumably related to semantic encoding about novel situations or rule-discovery. In addition, left putamen which contains a lot of dopamine receptors was activated too. By contrast, application process of commonness knowledge showed a significant activation in left precuneus (BA 7) which is mainly related to episodic memory retrieval. We suggest that these results could be applied on the construction of brain-based curriculum for science education.
