Traditional sensor technology courses are primarily theoretical, supplemented by a limited number of laboratory experiments. In these practical sessions, the focus is often placed on demonstrations and verification-based exercises, lacking activities designed to cultivate students' comprehensive skills and competencies. Consequently, students are rarely truly engaged, remaining instead in a state of passive reception. Furthermore, the laboratory components in many higher vocational institutions rarely address the real-world application of sensors. Even after completing the course, most students remain unable to properly select, install, or connect sensors for use in actual production or research and development—a disconnect that leaves the coursework detached from professional practice.
In many higher vocational colleges, education in sensor technology remains limited to the one-way transmission of knowledge. Many instructors are unclear about what students truly need to learn or how to effectively cultivate their practical skills. This issue manifests in several ways. First, regarding theoretical assessment, a student’s final grade is determined almost exclusively by their performance on the end-of-term examination, regardless of whether they have genuinely mastered the course material. Second, in terms of laboratory assessment, colleges often rely merely on attendance checks and the grading of lab reports; there is no evaluation of whether students have grasped the underlying experimental principles, which fundamentally neglects the development of their hands-on abilities. Finally, due to budgetary constraints, the instruction provided for this course is often purely formalistic, lacking off-campus practical training or internships, which leaves students with only a superficial understanding of the subject. Furthermore, this rigid, monolithic approach to both teaching and assessment prevents instructors from gaining a true grasp of their students' learning progress and diminishes meaningful interaction between them—ultimately resulting in a situation where both students and teachers merely go through the motions to fulfill their respective requirements.
In the teaching process, instruction should be tailored to the specific needs of different student groups. In higher vocational institutions, the focus should be on cultivating students' practical skills and comprehensive competencies; therefore, the curriculum should avoid overly abstruse theoretical analysis and complex mathematical derivations. Instead, the operating principles of sensors should be explained in a vivid and engaging manner. When covering the circuitry involved in sensors, instructors should employ straightforward, clear-cut explanations based on real-world applications—simplifying the material to make it more accessible and, in turn, sparking students' interest in the subject. Furthermore, the pedagogical focus should shift from sensor design to sensor application, enabling students to effectively utilize various sensors for detection purposes. The educational framework should prioritize the development of students' practical abilities, hands-on skills, and capacity for independent thought, ensuring that they truly learn how to apply their knowledge.
The fundamental approach is to simplify textbook material, making the content accessible and easy to understand, while integrating theoretical instruction with practical application—moving away from a model of rote, one-way transmission of knowledge. Furthermore, the focus of the curriculum should be tailored to the specific requirements of different majors, with specialized course designs for each. For instance, in programs related to electronic applications, the course on sensor technology should be comprehensive, requiring more instructional hours and intensive guidance. In contrast, for students in automation, the curriculum should be adjusted to the specific demands of that field: allocating fewer instructional hours and prioritizing the study of specific types of sensors—such as those for measuring mechanical quantities—while treating other topics primarily as introductory overviews. Adapting the curriculum to the needs of different majors not only alleviates the teaching burden on instructors but also enables students to engage with their studies more effectively and with greater ease.
