从知识整合到思维整合：生物技术专业临床课程“2.0整合式”标准化教学模式的建设研究

From Knowledge Integration to Thinking Integration: Constructing a Standardized “2.0 Integrated” Teaching Model for Clinical Courses in Biotechnology Undergraduate Programs

摘要: 针对生物技术专业临床课程长期存在的知识冗余与思维碎片化问题，本研究以“知识–思维双螺旋”理论框架为指导，聚焦三维虚拟仿真系统的教学应用效果，开展了一项为期两学期的准实验研究。实验组(n = 32)采用基于CT/MRI数据重建的“数字肝”“数字肺”虚拟仿真系统进行标准化操作训练，对照组(n = 30)沿用传统课堂讲授与动物实验模式。结果显示：实验组穿刺操作完成时间较对照组缩短23.6% (t = 4.82, p < 0.001)，操作错误率降低41.2% (χ² = 8.67, p = 0.003)，期末考核成绩提高18.4% (t = 3.91, p < 0.001)；学生满意度问卷评分实验组(4.52 ± 0.31)显著高于对照组(3.78 ± 0.45) (t = 7.64, p < 0.001)。研究证实，虚拟仿真系统能够有效提升生物技术专业学生的临床操作技能与知识整合能力，为整合式临床课程教学提供了可量化的实证依据。

Abstract: To address the persistent challenges of knowledge redundancy and thinking fragmentation in clinical courses for biotechnology undergraduates, this study, guided by the “knowledge-thinking double helix” theoretical framework, focused on evaluating the pedagogical effectiveness of a three-dimensional virtual simulation system through a two-semester quasi-experimental design. The experimental group (n = 32) received standardized operation training using “digital liver” and “digital lung” models reconstructed from CT/MRI data, while the control group (n = 30) followed conventional classroom lectures and animal-based experiments. Results indicated that the experimental group demonstrated a 23.6% reduction in puncture operation time (t = 4.82, p < 0.001), a 41.2% decrease in error rates (χ² = 8.67, p = 0.003), and an 18.4% improvement in final examination scores (t = 3.91, p < 0.001). Student satisfaction ratings were significantly higher in the experimental group (4.52 ± 0.31) compared to the control group (3.78 ± 0.45) (t = 7.64, p < 0.001). This study confirms that the virtual simulation system effectively enhances clinical operation skills and knowledge integration capabilities among biotechnology students, providing quantifiable empirical evidence for integrated clinical course teaching.
