In contemporary society, as technology advances, the interdisciplinary nature of academic fields continues to grow. In higher vocational colleges, the course on sensor technology—a core requirement for majors such as mechanical engineering, electronics, and automation—is characterized by a strong emphasis on both theory and practice. It is designed to equip students with the ability to select appropriate sensors, design and assemble various detection systems, and manage related circuitry—all of which contribute significantly to the development of a student's comprehensive professional competence. However, the course integrates key concepts from a wide array of other subjects; its content is extensive and fragmented, while also being closely tied to industrial production and scientific research. Furthermore, instruction often leans too heavily on theoretical knowledge, with rigid teaching methods and limited assessment approaches. Consequently, students struggle to master the material within a short timeframe, failing to effectively develop their hands-on and practical skills. This situation stands in stark contrast to the educational model prioritized by higher vocational institutions, which emphasizes the cultivation of practical skills over abstract theory. Therefore, it is essential to explore reforms in the teaching of sensor technology within higher vocational education. This paper proposes several actionable and practical measures aimed at enhancing teaching standards, improving instructional quality, and boosting student engagement. By doing so, it seeks to ensure that students achieve a better grasp of the subject, ultimately fostering the development of highly skilled professionals equipped with both practical expertise and innovative capabilities.
In traditional instruction for courses on sensor technology, educators often rely on a one-way transmission of theoretical knowledge. Given the broad scope of the subject—compounded by the fact that students frequently lack a strong foundational background—this approach often renders the classroom environment dull and unengaging, preventing students from becoming fully immersed in the course. Furthermore, the constant introduction of new material has accelerated the pace of instruction, increasing the academic burden on students and diminishing their motivation to learn. To date, many institutions continue to employ a monolithic pedagogical model that places excessive emphasis on classroom-based teaching; this leaves students unable to bridge the gap between theory and practice, thereby hindering the development of their practical and innovative capabilities. In short, most institutions face the following set of issues.
The course on sensor technology is an interdisciplinary, applied technical subject that draws upon knowledge from fields such as physics, chemistry, electronics, mechanics, materials science, and precision engineering. Within the current higher vocational education system, this course demands a high level of systematic knowledge, yet it is burdened with an extensive syllabus while being allocated relatively few teaching hours—a combination that places significant pressure on instructors. Consequently, whether in lesson preparation, classroom instruction, or the assignment of coursework, teachers often end up dedicating the vast majority of their time and energy to theoretical instruction. Faced with a heavy workload and limited time, many instructors resort to a "cramming" (or "spoon-feeding") pedagogical approach—bombarding students with large volumes of information while failing to monitor their actual level of comprehension, which renders the teaching process overly formalistic. Furthermore, despite the significant effort invested in theoretical instruction, the curriculum’s complexity and the rapid pace of delivery mean that students are often rushed into new chapters before they have mastered the preceding material. This makes it difficult for students to engage with the subject matter, leading to a sense of apathy or disengagement; ultimately, they fail to truly grasp the course content or internalize the knowledge presented in class.
