微课在“沉积岩石学”课堂教学中的应用——基于参加第八届全国高校微课教学比赛的思考

Application of Micro-lecture in the Course of Sedimentary Petrology:Based on the National University Micro-lecture Competition

以现代碳酸盐沉积环境微课在“沉积岩石学”课程教学中的应用为例,详细阐述微课中具体知识点的选取与引入,通过教学设计实现由现象到概念再到理论层次的升华后再回归现象本身,“深入浅出”讲透知识点的同时,使学生掌握独特的地学思维方式和解决问题方法。认为微课在一定程度上满足了“沉积岩石学”教学过程中因知识点繁多须有效节约师生时间的需求,允许学生进行有针对性、可重复性的学习,以弥补现有课堂学生主观能动性较差的不足,同时也是青年教师服务“沉积岩石学”课程建设目的、改善教学模式的新探索。

Taking the application of“modern carbonate sedimentary environment micro course”in the teaching of the Sedimentary Petrology course as an example,this paper expounds in detail the selection and introduction of specific knowledge points in the micro-lecture,realizes the sublimation from phenomenon to concept and then to theoretical level through teaching design,and then returns to the phenomenon itself.While“explaining in simple terms”the knowledge points,students can master the unique way of thinking and problem-solving.It is believed that micro-lecture meets the needs of effectively saving teachers and students’time due to a wide range of knowledge points in the teaching process of this course to a certain extent,allows students to study with pertinence and repeatability,and makes up for the deficiency of low subjective initiative of students,which is a new exploration for young teachers to serve the objective of the Sedimentary Petrology course construction and reform the teaching model.
