形近字是柬埔寨学生汉字学习中的主要难点之一。本文以柬埔寨禄山市公立华侨学校四年级30名学生为研究对象，对他们的形近字书写偏误情况进行调查研究，发现这些学生的形近字偏误主要有独体形近字和合体形近字两大类。针对上述偏误，从汉字结构、学习者自身特点、教学因素三方面进行分析，并据此提出一些可行的教学策略，帮助学习者减少形近字的偏误，深化汉字理解。

Similar Chinese characters constitute one of the major difficulties for Cambodian students in Chinese character learning. This paper takes 30 fourth-grade students from Lushan Public Overseas Chinese School in Cambodia as research subjects, and investigates their writing errors of similar Chinese characters. It finds that such errors mainly fall into two categories: those of similar single-component characters and those of similar compound characters. Based on the above errors, this paper analyzes the causes from three perspectives: Chinese character structure, learner characteristics and teaching factors. Accordingly, some feasible teaching strategies are put forward to help learners reduce similar-character errors and deepen their understanding of Chinese characters.
