基于学术启蒙视角下的湖光岩 教学设计探究——以“自然环境的整体性”为例

Exploring the Teaching Design of Huguangyan from the Perspective of Academic Enlightenment—Taking “Integrity of Natural Environment” as an Example

摘要: 地处雷州半岛的湛江湖光岩玛珥湖因其沉积物连续性好、分辨率高，是研究区域及全球第四纪气候环境变化的理想载体。本文的教学设计以人教版高中地理选择性必修1《自然地理基础》的“自然环境的整体性”为核心知识点，以湖光岩为教学素材，以学术引领为核心理念，以“古环境重建”、“古气候反演”等为切入点，将地球科学前沿研究成果转化为适用于高中生的课程资源。教学设计核心在于指导学生通过沉积物信息解译重建古气候。通过利用湖光岩沉积物的物理结构、化学成分以及生物化石等多源指标，设计反演历史时期的氧化还原环境、古温度、古降水等环境参数。

Abstract: Located on the Leizhou Peninsula, Zhanjiang’s Huguangyan maar lake is an ideal site for studying regional and global Quaternary climate and environmental changes due to its continuous sediment record and high resolution. This teaching design centers on the core concept of “the integrity of the natural environment” from the People’s Education Press high school geography elective textbook, Volume 1: “Fundamentals of Natural Geography”, using Huguangyan as a teaching resource. Guided by academic research, it introduces topics such as “paleoenvironmental reconstruction” and “paleoclimate inversion”, transforming cutting-edge Earth science findings into accessible course materials for high school students. The central goal is to guide students in reconstructing past climates through interpreting sediment data. By utilizing multiple indicators—including physical structure, chemical composition, and biological fossils of Huguangyan sediments, the design enables students to infer historical environmental parameters, such as redox conditions, paleotemperature, and paleoprecipitation.
