【摘要】 针对当前计算机网络课程群实验教学中综合性与系统性不足的问题，本文基于解决复杂工程问题所需的知识与能力要求，融合成果导向教育理念，提出一种“三层次”实验教学改革方案。通过引入3D虚拟仿真、网络场景虚拟化等技术，构建了虚实融合、层次递进的实验教学体系。实践结果表明，该方案有效提升了学生的综合实践能力。在网络与系统安全课程的考核中，课程目标1至5的达成度分别达到85%、73%、86%、55%与86%，较往届的75%、64%、67%、51%与85%均有明显提升。更多还原

【Abstract】 In response to the lack of comprehensiveness and systematicity in the current experimental teaching of computer network courses, this article proposes a "three-level" experimental teaching reform plan based on the knowledge and ability requirements required to solve complex engineering problems, integrating the Outcome Based Education(OBE) concept. By introducing technologies such as 3D virtual simulation and network scene virtualization, a virtual real fusion and hierarchical progressive experimental teaching system has been constructed. The practical results show that this program effectively enhances students’ comprehensive practical abilities. In the assessment of the Network and System Security course, the achievement rates of course objectives 1 to 5 reached 85%, 73%, 86%, 55%, and 86%, respectively, which were significantly higher than the previous levels of 75%, 64%, 67%, 51%, and 85%.更多还原
