网络直播在环境毒理学课程中的应用

【摘要】 随着网络直播走进大众生活，其在教学中的应用也不容忽视。网络直播具有即时性、同步性和现场感等众多优点，对于内容较为抽象且理论性较强的环境毒理学课程而言，网络直播的实时互动、较强的参与感都有利于对知识的形象化处理和掌握。该文通过实际直播案例、名师直播授课、在线观察模式生物和观摩生态毒理实验，以及实时互动答疑等教学环节，发现100%的学生认为通过直播对了解环境毒理学前沿研究有帮助，对环境毒理学领域感兴趣的比例达到88.9%，几乎所有同学对学习效果满意。由此可见，网络直播作为线下传统授课方式的补充，有助于激发学生的学习兴趣和参与度，提高课程的学习效果。更多还原

【Abstract】 As webcasting becomes popular in our daily life, its application in teaching cannot be ignored. Webcasting has many advantages such as immediacy, synchronization and sense of presence. For the theoretical course Environmental Toxicology, the realtime interaction and strong sense of participation of webcasting are conducive to the visualization of knowledge. Through the actual webcasting case, including live lectures by well-known teacher, online observation of model organisms and toxicity experiment process,and real-time interactive Q&A activities, it is found that 100% of the students thought that the webcasting is helpful to understand the frontier research of Environmental Toxicology. The proportion of interested students reached to 88.9%, and almost all students were satisfied with the learning effect. It can be seen that, as a supplement to traditional offline teaching methods, webcasting helps to stimulate students’ learning interest, improve participation, and enhance the learning effect of the course.更多还原
