针对当前室内实验模式存在的不足，提出一种户外开放性实验模式，论述了其基本原理，给出了其构建方式与实施方法，并结合电磁场实验课程进行了户外开放性实验模式的应用探索。结果表明：户外开放性实验模式有利于学生对抽象概念的认知，增强学生的工程实践技能，调动学生的实践积极性，培养学生的创新精神。但户外开放性实验模式涉及到的许多问题尚需进一步探索和研究。

Based on the research and exploration of the recent experiment mode, we proposed an outdooropening experiment mode. We elaborated its basic principles, put forward its construction and application methods, and carried out the outdooropening experiment in electromagnetic field experimental course. The result shows that the outdooropening experiment mode is helpful for students’ cognitive ability of abstract conception, improves their practical ability, brings their enthusiasm into practice, and cultivates their innovation spirit. However, relative problems of the mode need further exploration and research.
