基于设计研究的工科研究生课程改革与实践——以《辐射测量与仪器》研究性教学模式构建为例

Design-Based Research on Engineering Graduate Course Reform and Practice—A Case Study of Developing a Research-Based Teaching Model for “Radiation Measurement and Instruments”

摘要: 为深化研究生对辐射测量原理的理解并强化其工程实践能力，本研究在《辐射测量与仪器》课程中实施了以“不同类型辐射测量仪器的设计与实现”为核心的研究性教学改革。通过将课程知识点融入完整的仪器设计与实现流程，引导学生经历从需求分析、方案设计、模块选型、软硬件实现到系统测试的全过程。实践表明，该模式有效激发了学生的主动探索精神：所有学生小组均成功完成了辐射测量仪器的原型样机的开发，其设计方案在创新性和可行性方面获得行业专家的肯定；学生在系统设计、工程实现和问题解决等方面的能力得到显著提升，多项设计成果展现出实际应用潜力。本改革验证了以仪器设计与实现为载体的实践教学模式对培养工科研究生工程创新能力的重要价值，为同类课程建设提供了具有参考意义的实施范式。

Abstract: To deepen graduate students’ understanding of radiation measurement principles and enhance their engineering practical abilities, this study implemented a research-oriented teaching reform in the “Radiation Measurement and Instruments” course, centered on the “design and implementation of different types of radiation measurement instruments.” By integrating course knowledge points into the complete process of instrument design and implementation, students were guided through the entire workflow—from requirements analysis, scheme design, and module selection to software/hardware implementation and system testing. Practice has demonstrated that this model effectively stimulates students’ initiative in exploration: all student groups successfully developed prototype instruments for radiation measurement, with their design solutions receiving recognition from industry experts for innovation and feasibility. Students’ capabilities in system design, engineering implementation, and problem-solving showed significant improvement, and several design outcomes demonstrated potential for practical application. This reform validates the importance of a practice-oriented teaching model, based on instrument design and implementation, for cultivating the engineering innovation capabilities of graduate engineering students, providing a referential implementation paradigm for the development of similar courses.
