基于科教融合理念的法庭科学实验教学研究——电化学显现潜在手印

Experiment Teaching of Forensic Science Based on Integrating Science and Education:Electrochemical Development of Latent Fingerprints

手印显现提取实验课程涉及到化学学科的许多理论和技术,是法庭科学专业实验教学体系中的重难点。传统实验课程缺乏对学生创新意识、创新思维和创新能力的培养,难以满足公安院校培养创新型人才的要求。基于科教融合理念,以“电化学显现潜在手印”为案例开展实验教学设计,从课前引导、课中实践和课后反馈等3个环节优化实验内容并明确实施过程。通过在实践层面构建实验教学新模式,为推动法庭科学实验教学改革提供参考。

Experiment courses of fingerprint development and extraction that relate to many theories and technologies in chemistry are difficult but important in the experiment teaching system of forensic science.Consciousness,thinking and capability of innovation of the students cannot be well trained in traditional experiment courses,which is not adequate for police universities to cultivate innovative talents.Based on the concept of integrating science and education,electrochemical development of latent fingerprints has been chosen as a case for the design of experiment teaching.Experiment content and implementation process of three experiment teaching stages,including the instruction before class,the practice during class,and the feedback after class,have been optimized and clarified.A new mode of experiment teaching has been constructed from the practical level,providing guidance on the reform of experiment teaching of forensic science.
