“双减”背景下的初中地理大单元教学设计研究
Research on the Design of Large-Unit Instruction of Junior High School Geography under the Background of “Double Reduction” Policy

“双减”政策的实施推动了新一轮教学改革浪潮的兴起。文章通过深入分析初中地理大单元教学现状，设计了围绕概念，设计主题；整合内容，确定目标；基于目标，预设评价；确定问题，自主探究；知识迁移，能力提升等五步大单元教学设计流程，并以“中国的水资源”为例进行了案例展示，以期构建更加高效、科学的地理教学模式，为促进学生的全面发展与“双减”背景下的“提质增效”提供一定参考。
The implementation of the “double reduction” policy has promoted a new wave of teaching reform. This article, through in-depth analysis of the current situation of large-unit teaching of junior high school geography, designs a five-step large-unit teaching design process of “designing themes around concepts; integrating content to determine goals; presetting evaluations based on goals; determining problems for independent inquiry; transferring knowledge and improving abilities”. Taking “water resources in China” as an example, a case is demonstrated to build a more efficient and scientific geography teaching model, providing a certain reference for promoting students’ comprehensive development and “improving quality and efficiency” under the background of “double reduction”.
