重组DNA技术可视化教学实践

Visual teaching practice of recombinant DNA technology

重组DNA技术是分子生物学课程的重要内容之一,但其知识抽象难懂,增加了学习的难度。在教学过程中,充分利用可视化手段剪辑视频、绘制对比图、流程图和思维导图、制作交互动画,将文字知识及思考路径以可视化的形式呈现,能够降低知识的认知负荷,促进学生的思维发展。同时,教学中注重课程思政元素的挖掘,以可视化的形式传递,提升立德树人实效。

Recombinant DNA technology is one of the important contents of molecular biology courses,but its knowledge is difficult to understand,which increases the difficulty of learning.In the teaching process,we make full use of visual means to edit videos,draw comparison charts,flow charts and mind maps,and create interactive animations,presenting textual knowledge and thinking paths in a visual form,reducing the cognitive load of knowledge,and promoting students'thinking development.At the same time,attention should be paid to the excavation of ideological and political elements in the curriculum,which should be conveyed in a visual form to enhance the effectiveness of moral education and talent cultivation.
