运用GeoGebra软件实现复变函数可视化教学的探索与实践

Exploration and Practice of Teaching Visualization of Complex Functions byGeoGebra

为推动技术与教育教学精准融合,探讨可视化方法在工科复变函数课程教学中的意义与实施效果是重要且必要的。文章根据复分析可视化资源库的建立步骤,利用GeoGebra软件制作可视化文件;再将可视化资源有机融入教学设计中,遵循“观察―发现―讨论―归纳”的学习过程;最后通过教学实践结果,反映出复变函数可视化教学收效显著。数形结合思想的贯穿使教学过程高效,使学生思路开阔,有利于高技术应用型人才的培养。

In order to promote the precise integration of technology teaching,it is important and necessary to explore the significance and implementation effect of visualization methods in the complex function courses.According to the establishment steps ofthe visual resource library of complex analysis,the visual file is made by GeoGebra.Then the visual resources are organically integrated into the teaching design,following the learning process of"observation-discoverydiscussion-summarization".Finally,through the results of teaching practice,it is reflected that the visual teaching of complex variable function has achieved remarkable results.The combination of number and shape makes the teaching process efficient and broadens the students thinking,which is conducive to the cultivation of high-tech applied talents.
