With the development of sensor technology, the course content has expanded rapidly, and traditional teaching ideas and models are no longer adequate to meet the course's needs. However, a new teaching model based on "student-centered + teacher-guided" can maximize the guiding role of teachers and the initiative of students, thus making the new teaching model more suitable for the rapid development of the "Sensor Technology and Applications" course.

  Under the new teaching model, the course employs a combination of teacher-led instruction, case studies, and group discussions. The teaching process emphasizes using everyday examples and engineering cases to inspire students, guiding them to discuss the fundamental principles and knowledge of sensors involved in these examples and cases. This fully leverages students' active role in the learning process, thereby stimulating their enthusiasm and fostering their independent thinking, analytical, and problem-solving abilities, gradually cultivating their ability to apply theoretical knowledge in engineering. Furthermore, to facilitate students' previewing of the basic knowledge covered in the course, after each lesson, the teacher lists the basic knowledge points for the next lesson, allowing students to review promptly and ensuring effective learning for the next lesson.

  In terms of teaching methods, a variety of teaching methods are adopted, and multimedia teaching, blackboard teaching and physical teaching are organically combined. The course makes full use of the characteristics of multimedia teaching, which can organically combine information carriers such as concepts, graphics, animation, video and sound [4]. Some teaching contents that are difficult to express and phenomena that cannot be observed by traditional blackboard teaching methods are vividly presented to students in a graphic and flexible multimedia way, ensuring that students can establish relevant concepts of sensor technology from a cognitive perspective, and striving to optimize the teaching process and teaching effect. For theoretically abstract teaching contents (such as the chapter on sensor dynamic characteristics), a combination of blackboard teaching and simulation demonstration is adopted. Through detailed derivation and simulation of formulas, students' understanding and mastery of formulas are deepened. For teaching contents with strong application (such as sensor principles, signal conditioning, etc.), a combination of multimedia teaching, blackboard teaching and physical teaching is adopted to improve students' engineering application ability of teaching contents.

  Regarding course assessment, the traditional "closed-book exam" model has several drawbacks: firstly, students cram at the last minute, neglecting their regular studies; secondly, it is difficult to assess students' ability to comprehensively apply knowledge. To address these shortcomings, a new assessment system is proposed: "20% for homework + 30% for class discussion participation + 50% for the final exam." This avoids the inadequacy of relying solely on exam results to determine performance. The new system emphasizes promoting students' learning initiative and assessing their ability to comprehensively apply knowledge. Homework primarily consists of major assignments, focusing on cultivating students' exploratory spirit and comprehensive knowledge application skills. Class discussions use engineering case studies, assessing students' enthusiasm and initiative in analysis and discussion, and cultivating their ability to analyze and solve problems using knowledge. Simultaneously, a closed-book exam is used at the final exam to assess students' mastery of fundamental course knowledge, ensuring their understanding and mastery of basic concepts.

  The exploration of reforms in the teaching of the course "Sensor Technology and Applications" has made us fully realize that teaching reform is a process that keeps pace with the times. In the future teaching process, there is still room for further optimization and improvement of course content, teaching methods, teaching tools and assessment system.
