电波测量课程“三性”实验教学改革与实践

Reform and Practice of the “Three-Dimensional” Experimental Teaching in Radio Wave Measurement Course

  • 摘要: 工程教育专业认证背景下,实验教学体系改革成为培养创新型工程人才的关键突破口。该文以电子信息类核心课程电波测量为研究对象,构建了“基础层—综合层—创新层”三阶递进的实验教学体系。通过引入虚拟仿真与硬件实测双平台,开发了覆盖微波参数测量、天线特性分析、电磁兼容测试等六大模块的32个实验课程项目,形成“虚实结合、理实交融”的新型教学模式,提出了“三维评价矩阵”,将过程性评价与成果性评价相结合,构建了包含5个一级指标、12个二级指标的多维度评价体系。实践表明,教学改革后学生工程实践能力测评优良率提升27.8%,创新项目参与度提高42.5%,优化了实验教学内容和方法,强化了实验教学的实践性和创新性,提高了学生的实验技能、工程实践能力和创新思维能力,验证了该教学体系的有效性。

     

    Abstract: Under the background of engineering education professional accreditation, the reform of experimental teaching systems has become a key breakthrough in cultivating innovative engineering talents. Taking Radio Wave Measurement, the core course in the electronic information field, as the research object, this study constructs a three-tier progressive experimental teaching system comprising the Fundamental Layer, Comprehensive Layer, and Innovative Layer. By introducing a dual platform of virtual simulation and hardware-based measurement, 32 experimental course projects covering six major modules, including microwave parameter measurement, antenna characteristic analysis, and electromagnetic compatibility testing, are developed, forming a new teaching model of virtual-real integration and theory-practice combination. Furthermore, a three-dimensional evaluation matrix is innovatively proposed, combining process-oriented assessment with outcome-based assessment to establish a multidimensional evaluation system with five primary indicators and twelve secondary indicators. Practical results show that after the teaching reform, the excellent rate of students’ engineering practice ability assessment increased by 27.8%, and participation in innovation projects rose by 42.5%. The reform effectively optimizes experimental teaching content and methods, strengthens its practicality and innovativeness, and improves students’ experimental skills, engineering practice capabilities, and innovative thinking abilities, thereby verifying the effectiveness of this teaching system.
