面向物联网专业新生的无线传感器网络课程教改实践

Teaching Reform Practice of Wireless Sensor Networks Course for IoT Freshmen

摘要: 物联网类专业核心课程知识密度高、理论性强，常使新生望而生畏。本文以“无线传感器网络”课程为试点，针对其作为物联网类学生首门专业基础课的定位，开展教学改革。改革核心在于：弱化高深理论，重点聚焦于通信传输基本思想与总体目标的建立；通过通俗化教学语言与前沿应用场景激发学习热情；以物联网前沿动态为桥梁，帮助学生平稳迈入通信领域门槛。实践表明，改革显著提升了教学效果：学生普遍反馈课程对后续学习有正向作用(问卷调查)，对通信领域建立了基础认知；期末考试通过率达97.1% (68人中仅2人未通过)，为后续专业学习奠定了坚实基础。

Abstract: Core courses for IoT-related majors, characterized by high knowledge density and strong theoretical rigor, often intimidate freshmen. This paper takes the “Wireless Sensor Networks” course as a pilot to implement teaching reforms, leveraging its positioning as the first foundational professional course for IoT students. The core of the reforms includes downplaying sophisticated theories to focus on establishing the basic concepts and overarching goals of communication transmission, stimulating students’ enthusiasm through accessible teaching language and cutting-edge application scenarios, and using the latest developments in IoT as a bridge to help them smoothly transition into the field of communications. Practice shows these reforms have significantly improved teaching effectiveness. Questionnaire surveys indicate students generally recognize the course’s positive impact on subsequent studies and have developed a basic understanding of communications. With a final exam pass rate of 97.1% (only 2 out of 68 students failed), the course has laid a solid foundation for their further professional learning.
