线上-线下结合的大气污染控制工程课程混合式教学模式改革——以大连理工大学环境学院为例

【摘要】 大气污染控制工程是本科环境学科重要的专业必修课，在环境科学与工程专业学生的培养过程中起着举足轻重的作用。新冠感染疫情防控常态化背景下，从线上-线下混合式教学建设的视角对该专业课程进行教学改革与创新具有一定的现实意义。基于信息技术与教学的深度融合，在教学实践的基础上，从线上资源建设、线下教学内容调整和课程考核方式样化三方面开展大气污染控制工程课程线上-线下混合式教学模式的构建。与传统线下教学模式和单一的线上教学模式相比，线上-线下混合式教学既可弥补传统线下教学模式存在的填鸭式教学问题，同时又可避免单一线上教学过渡依赖学生自学的问题。一方面，混合式教学模式有利于提升学生的自主学习、独立思考和专业创新能力；另一方面，还能促进以学生为中心的教育理念转变，提高教学质量，加深学生对课程知识的理解与掌握。作为传统课堂和线上教学两方面相结合的线上-线下混合式教学可能会成为未来教学方法改革的方向。更多还原

【Abstract】 Air Pollution Control Engineering is a vital specialized course for undergraduate students majoring in environmental science and engineering, which plays an important role in the training process. Under the background of normalize the COVID-19epidemic prevention, it is of practical significance to carry out teaching reform and innovation from the perspective of online-offline mixed teaching construction. Based on the deep integration of information technology and teaching practice, the online-offline hybrid teaching mode of Air Pollution Control Engineering is constructed from three aspects: online resource construction, offline teaching content adjustment and diversified course assessment methods. Compared with traditional offline teaching mode and single online teaching mode, online-offline hybrid teaching not only makes up for the problems of spoon-feeding teaching existing in the traditional offline teaching mode, but also avoids the problem of single online teaching relying too much on students’ self-study. On the one hand, hybrid teaching mode is beneficial to improve students’ ability of independent learning, independent thinking and professional innovation; on the other hand, it can also promote the transformation of student-centered education concept, improve teaching quality,and deepen students’ understanding and mastery of course knowledge. As a combination of traditional classroom and online teaching,online-offline hybrid teaching may become the direction of future teaching reform.更多还原
