PBL教学在遥感数字图像处理课程双语课程建设中的探索与实践

Exploration and Practice of PBL Teaching in Bilingual Course Construction of Remote Sensing Digital Image Processing

双语教学是我国高等教育适应经济全球化的必然选择,也是高等院校教育教学改革的重点内容之一。该文首先从教学资源、语言角色、教学实践等角度分析当前双语教学中存在的问题。其次,探讨了基于PBL(Problem-Based Learning)的双语教学模式在本科生遥感数字图像处理课程教学上的应用,从课前预习、课内深化、课后巩固三个维度阐述双语课程构建方式,并深入分析这种新型教学模式对学生的促进作用。实践结果表明,基于PBL的双语教学能够有效地提升学生在不同语言环境下的思维和表达能力,拓宽学生的国际视野,达到利用英文的思维逻辑体系看待问题、解决问题的目的,为课程今后实现全英文授课提供有力支撑,并使教师可以在实践中逐步发现问题和解决问题,不断深入指导其他课程的双语教学改革。

Bilingual teaching is an inevitable choice for higher education in China to adapt to economic globaliza⁃tion,and it is also one of the key contents of education and teaching reform in higher education institutions.This article first analyzes the problems existing in current bilingual teaching from the perspectives of teaching re⁃sources,language roles,and teaching practices.Then,it discusses the application of the PBL-based bilingual teaching model in the undergraduate remote sensing digital image processing course,elaborating on the construc⁃tion of bilingual courses from three dimensions:pre-class preview,in-class deepening,and post-class consolida⁃tion,and deeply analyzing the promoting effect of this new teaching model on students.The practice results show that PBL-based bilingual teaching can effectively improve students’thinking and expression abilities in different language environments,broaden students’international perspectives,and achieve the goal of using English think⁃ing logic system to view and solve problems.It provides strong support for achieving full English teaching in the future,and can gradually discover and solve problems in practice,continuously guiding the bilingual teaching re⁃form of other courses.
