Three dimensions of metaphor in education

Metaphor serves as a powerful tool to reveal the intrinsic relationship between language and human thought, as well as between language use and individual cognition. Despite extensive research on metaphor in general linguistics, its specific roles in the context of education remain underexplored, particularly regarding its multidimensional functions in human activity. This study aims to examine the roles of metaphor in educational practice through a combination of diachronic and horizontal approaches. It focuses on three dimensions: dissemination of thought, clarification of thought, and research on thought. The methodology involves a detailed analysis of these dimensions, supported by theoretical principles and relevant scientific literature, illustrated with concrete examples. Findings indicate that metaphor has long been integral to educational practice, enhancing understanding, communication, and knowledge construction. Its enduring use underscores its effectiveness in facilitating social interaction and cognitive development. The study highlights the importance of integrating metaphorical analysis in educational research and practice to foster a more nuanced understanding of teaching and learning processes.
