高中生物学“检测生物组织中的糖类、脂质和蛋白质”实验的试剂盒化研究

Research of Kits for the High School Biology Experiment “Detection of Sugars, Lipids and Proteins in Biological Tissues”

摘要: 传统高中生物学“检测生物组织中的糖类、脂质和蛋白质”实验存在试剂配制备繁杂、操作容错率低、结果可比性差等问题，制约了其核心教学价值的实现。为解决此问题，本研究开发了一套适用于中学教学场景的集成化实验试剂盒。基于“需求分析–原型设计–教学试做–迭代优化”路径，试剂盒采用了固体试剂预分装、标准化生物样本、定量化塑料耗材及图示化流程引导等系统性设计。通过三轮共计1200人次的教学实践验证，该方案使教师的课前准备时间缩短约85%，学生操作失误率减少75%，核心实验环节的平均显色成功率从58%提升至92%以上。研究结果表明，试剂盒化方案在提升教学效率、保障实验安全、降低资源门槛及促进操作标准化方面成效显著，有效支撑了从验证性实验向探究性活动的平稳过渡。本研究为“技术降维适配”教育需求、推动中学生物实验教学的规范化与公平化提供了具有借鉴价值的技术路径与实践范式。

Abstract: The traditional high school biology experiment “Detection of Sugars, Lipids and Proteins in Biological Tissues” faces challenges such as cumbersome reagent preparation, low operational fault tolerance, and poor result comparability, which hinder the realization of its core pedagogical value. To address these issues, this study developed an integrated experimental kit suitable for secondary school teaching scenarios. Following a “needs analysis-prototype design-pilot teaching-iterative optimization” framework, the kit incorporates systematic designs including pre-packaged solid reagents, standardized biological samples, quantitative plastic consumables, and illustrated procedural guides. Through three rounds of teaching practice involving a total of 1200 participants, the kit-based approach reduced teachers’ pre-class preparation time by approximately 85%, decreased student operation error rates by 75%, and improved the average success rate of the core color development step from 58% to over 92%. The results demonstrate that the kit-based solution is highly effective in improving teaching efficiency, ensuring experimental safety, lowering resource barriers, and promoting operational standardization. It effectively supports a smoother transition from verification experiments to inquiry-based activities. This study provides a valuable technical pathway and practical paradigm for “technology downscaling and adaptation” to educational needs, and for promoting standardization and equity in middle school biology experiment teaching.
