摘要

探究实践是提升小学生科学核心素养的重要途径，也是引导学生探索一个科学现象从“不可能”到“可能”的必经之路。传统金属导体在质量、柔性与制备成本等方面的局限，催生了柔性导电材料的技术革新，进而为电子科技发展提供了全新路径。本研究基于中小学科学教育需求，设计科普实验课程：制备聚(3

4-乙烯二氧噻吩)-聚苯乙烯磺酸(PEDOT:PSS)导电纸实现普通纸张的导电功能化改造，引入十二烷基苯磺酸(DBSA)改性技术进一步优化其导电性能，系统对比普通纸(绝缘体)、基础导电纸(半导体)和改性导电纸的电阻特性差异。基于戴维·库伯提出的“学习圈”理论，创新设计了强调持续反思与动手实践相结合的实验流程，引导学生对实验进行“观察—测量—分析—反思”，帮助学生理解背后的原理，突破纸张不能导电的思维定式，认识新材料在柔性电子领域的应用潜力，培养青少年的科学认知态度与创新思维能力。

Abstract

Exploratory practice is conducive to developing the core scientific competency of primary school students

and it is also important to show students how a scientific phenomenon can be transformed from impossible to possible. The limitations of traditional metal conductors in terms of quality

flexibility

and fabrication cost give rise to technological innovation in flexible conductive materials and provide a new route for the development of electronic science and technology. Based on the needs of science education in primary and secondary schools

this study designed an engaging science experiment course focused on preparing poly(3

4-ethylenedioxythiophene)-poly(styrenesulfonate) (PEDOT:PSS) conductive paper. This initiative aimed to facilitate the functional transformation of ordinary paper into a conductive medium by introducing dodecylbenzenesulfonic acid (DBSA) modification technology to further enhance its conductivity. The experimental design systematically compared the resistance characteristics of ordinary paper (an insulator)

basic conductive paper (a semiconductor)

and modified conductive paper. Therefore

this study employs the learning circle theory proposed by David Kolb to design an experimental process that emphasizes the combination of continuous reflection and hands-on practice. During this process

students can experience the chain of “observation—measurement—analysis—reflection” to help them dismantle preconceived notions regarding the electrical non-conductivity of paper while highlighting the application potential of novel materials within flexible electronics. Ultimately

this study aimed to foster students’ scientific awareness and innovative thinking concerning functional materials.
