本文以促进高中地理深度学习为目标，构建“任务链—问题链”融合的教学模式，并以伊犁察县白石峰地貌观察为例开展教学设计。该设计通过“拾级而上—登顶俯瞰—探幽入微”的认知路径，引导学生经历地貌特征识别、成因推理与人地关系分析的全过程，实现从感知到迁移的深度认知发展；运用表现性评价量规以保障教学评一致，有效提升学生的地理实践力与综合思维。这一模式可为地貌类内容的深度学习提供了参考。

This paper aims at deep learning of high school geography, constructs the teaching mode of "task chain and problem chain", and carries out the teaching design by taking the observation of the landforms of Bashi Peak in Yili Cha County as an example. Through the cognitive path of "climbing up to the top and overlooking the peaks and exploring the depth", students are guided to go through the whole process of identifying geomorphological features, reasoning about the causes and analyzing the relationship between people and land, so as to realize the development of deep cognition from perception to migration. In this paper, we also design a performance evaluation scale to ensure the consistency of teaching and assessment, and eff ectively enhance students' Geography Praxis and Holistic Thinking. This model provides an operational teaching design model for the in-depth learning of geomorphology content in senior high school geography.
