Research on Teaching Activities of Local Geography in Middle Schools Based on 3S Technology—Taking the Mountain Climbing Activity in Mangdang Mountain as an Example

随着信息技术的蓬勃发展，3S技术(地理信息系统GIS、遥感RS、全球定位系统GNSS)作为一种先进的信息技术手段，逐渐渗透到教育领域，其在教育领域的应用价值日益凸显，为地理教学带来了全新的发展机遇与变革动力。在中学地理教学体系中，乡土地理作为连接学生生活实际与地理学科知识的重要纽带，对于培养学生的区域认知、地理实践力以及对家乡的热爱之情具有不可替代的作用。然而，传统的乡土地理教学方法在信息呈现的直观性、动态性以及教学内容的丰富度等方面存在一定局限性。本研究旨在深入探究3S技术在中学乡土地理教学中的应用模式与效果，通过理论与实践相结合的方式，为提升中学乡土地理教学质量提供科学依据与实践范例。本研究为3S技术在中学乡土地理教学中的推广与应用提供了实践经验与参考案例，不仅能够拓展教学空间、提升教学效率，同时也为地理教学改革与创新提供了新的思路与方法，有助于推动中学地理教学质量的提升，培养学生的综合地理素养。With the vigorous development of information technology, 3S technologies (Geographic Information Systems, GIS, Remote Sensing, RS, Global Positioning Systems, GNSS) as advanced information technology tools have gradually permeated the education sector. Their application value in education is becoming increasingly prominent, bringing new development opportunities and transformative momentum to geography teaching. In the secondary school geography curriculum, local geography serves as a crucial link between students’ real-life experiences and geographical knowledge, playing an irreplaceable role in fostering students’ regional awareness, geographical practice skills, and affection for their hometowns. However, traditional local geography teaching methods have certain limitations in terms of the intuitiveness and dynamism of information presentation and the richness of teaching content. This study aims to delve into the application models and effects of 3S technologies in secondary school local geography teaching. By combining theory with practice, it seeks to provide scientific evidence and practical examples for improving the quality of secondary school local geography teaching. This research offers practical experience and reference cases for the promotion and application of 3S technologies in secondary school local geography teaching, not only expanding teaching space and enhancing teaching efficiency but also providing new ideas and methods for geography teaching reform and innovation. It helps to improve the quality of secondary school geography teaching and cultivate students’ comprehensive geographical literacy.
