基于项目式学习的高校微生物学实验课教学改革

Revamping of Microbiology laboratory teaching in universities through project-based learning

摘要:

微生物学是生命科学领域的基础学科，在高校生物专业教学中处于核心地位。然而，传统的微生物实验教学存在实验内容分散、缺乏内在联系等问题，影响学生深入理解和应用实验技能、知识，也不利于激发学生学习的主动性和探索精神。为进一步提升微生物学实验课程质量，本研究借鉴了项目式教学方法，通过引入科赫法则，改进了微生物学实验教学的教育理念、教学模式、教学方法和评估体系。以家蚕和苏云金芽孢杆菌为实验材料，我们重现并验证了科赫法则这一经典理论，深入探究了传染性疾病与病原微生物之间的因果关系。改进后的教学方案有助于激发学生的实验热情，提高其实验技能，培养其批判性思维能力，并提升其科学素养和创新能力。

Abstract:

Microbiology stands as a foundational discipline in life sciences and plays a pivotal role in the biology curriculum of universities. However, the conventional microbiology laboratory teaching faces issues such as content fragmentation with a lack of inherent connections. These challenges hinder students to deeply comprehend and apply experimental skills and knowledge. Moreover, the conventional teaching fails to stimulate students' self-directed learning and exploratory spirit. To enhance the quality of microbiology laboratory teaching, we draw inspiration from project-based learning. With the introduction of Koch's postulates, a fundamental theory, as the goal, we improved the educational philosophy, teaching modes, teaching methods, and assessment system. Using silkworm and Bacillus thuringiensis as the experimental subjects, we reproduced and confirmed Koch's postulates, and probed into the cause-and-effect relationship between infectious diseases and pathogenic microorganisms. Our improved teaching approach aims to kindle students' passion for experimentation, refine their practical skills, nurture their critical thinking, and elevate their scientific literacy and innovative capabilities.
