部件教学法是国际中文教育最常用到的一种汉字教学方法，具有重要价值。本文结合汉字三平面理论，从“形体”“构意”“职用”三个视角对此方法进行重新探讨。研究结果显示，部件教学法通过将汉字拆分为基本部件，帮助学习者更好地理解和记忆汉字结构，从而提高学习效率。然而，部件教学法也存在一些不足，如可能忽视字音字义、难以区分形近字、教学顺序可能存在问题等，因此，需要与其他教学方法相结合，取长补短，以更好地完成汉字教学任务，提高学习者的汉字学习效果。

The component-based teaching method is one of the most widely used approaches in international Chinese language education for teaching Chinese characters and holds significant value. This paper re-examines this method from three perspectives— "form," "meaning," and "function" —by integrating the three-plane theory of Chinese characters. The research findings indicate that by breaking down characters into basic components, the component-based teaching method helps learners better understand and memorize character structures, thereby enhancing learning efficiency. However, the method also has limitations, such as potential neglect of pronunciation and meaning, difficulty in distinguishing similar-looking characters, and possible issues with the teaching sequence. Therefore, it should be combined with other teaching methods to complement each other's strengths and weaknesses, thereby more effectively achieving Chinese character teaching objectives and improving learners' proficiency.
