节点是曲线中的控制点,其对曲线的形状起决定性作用。同样,地理知识网络也存在某些关键节点,本文称之为“关键知识”。这些关键知识控制着知识成分的性质、延伸方向及迁移性能等,进而影响着学生的地理认知结构,而认知结构水平又影响着学生的思维品质及解决问题的思维能力。一、以关键知识为核心,构筑地理知识结构认知结构迁移理论认为,学生已有的认知结构是实现学习迁移的重要因素。关键知识链接着不同的知识 A node is a control point in the curve, which plays a decisive role in the shape of the curve. Similarly, there are some key nodes in the geographic knowledge network, which we call “key knowledge”. These key knowledge control the nature of knowledge components, extend the direction and migration performance, which in turn affect the students ’geographical cognitive structure, and the cognitive structure affects the students’ thinking quality and problem-solving thinking ability. First, take the key knowledge as the core and construct the cognitive structure of the geographical knowledge structure Theory of transfer that the existing cognitive structure of students is an important factor to achieve learning transfer. Key knowledge links different knowledge
