Abstract:
The construction of teaching cases in textile specialty courses is extremely important. By deconstructing the classic paper “On a New Kind of Rays” from the journal Nature, the paper reveals its pioneering contributions to development and modern characterization techniques. The study argues that Röntgen’s discovery of X-rays was a significant contribution, and the resulting method of tracing to observe internal structures inspired the textile pioneer Mr. Yan Haojing to invent the tracer fiber method, making a foundational contribution to the study of yarn structure. The text constructs teaching case resources through historical facts, timelines, personalities, characteristics, and critiques, serving as teaching cases and course ideological and political materials for textile specialty foundation courses, which have been applied in various teaching scenarios with good results.
纺织专业课程的教学案例构建极其重要。通过解构《自然》期刊中《论一种新型的射线》这一经典论文,揭示了其在显影及现代表征技术方面所做出的开创性贡献。研究认为:伦琴发现X射线的贡献意义非凡,由此而诞生的利用示踪观察内部结构的表征方法,启迪了纺织先贤严灏景先生发明示踪纤维法,进而在纱线结构研究方面做出了奠基性的贡献。文中通过史实、时间、人物、特点、评述等要素构建了教学案例资源,此类资源既是纺织专业基础课程的教学案例素材,也是极好的课程思政素材,且已在不同类型的教学场景中进行了应用,应用效果良好。
