细菌革兰氏染色探究式实验教学的设计和 实施效果分析

Experimental design and efficiency assessment of Bacterium gram stain based on inquiry teaching

摘要:

细菌革兰氏染色效果受多种因素的影响, 基于探究式教学法的理论原则, 本文将固定方式和脱色时间两个关键因素设计成梯度对比实验, 通过结果的直观差异性使教学效果显著提高。更为重要的是, 学生在分组和组内实验探索过程中, 通过内在好奇心和外在具体任务的双重驱动, 主体的创新精神得到激发, 情感价值体验得到满足, 创新意识、动手能力、思维品质和协作精神都得到了明显的提升。实践证明, 针对特定问题巧妙设计探索引导实验, 不仅可以增强学生的实践动手能力, 提升教学效果, 而且可以充分调动学生的主体积极性, 激发创新意识和培养严谨的科研思维品质。

Abstract:

The effect of Bacterium Gram stain is influenced by many factors. In our class the teaching efficiency was significantly improved with the application of inquiry-based teaching, through which the key factors of fixed patterns and decoloration time were systematically designed and the difference was presented visually. Under the driving forces of intrinsic curiosity and specific assignments, moreover, the many performances of students, such as initiative consciousness, thinking traits, problem-solving ability, team spirit, were stimulated and cul-tured during the inquiring process. Practically, the problem-oriented experimental design not only strengthens the skill and enhances the teaching efficiency, but also mobilize the enthusi-asm, stimulate the initiative consciousness and culture the scientific thinking traits.
