摘要
化学知识“提取困难”归纳为4种表现：不能及时提取相关知识；不能独立提取相关知识；不能准确提取相关知识；不能全面提取相关知识。化学知识“提取困难”的原因有：知识内容不熟悉；知识意义不明确；知识连接不清晰；知识网络不完善；知识情境不真实；知识负迁移效应等。克服知识“提取困难”对策主要包括：优化教学方式，注重学生的知识“输出”；营造真实环境，促进知识迁移；围绕核心概念，建立知识连接；理清知识关系，完善知识网络；精心设计问题，加强自我监控；辨清新旧联系，克服定式干扰等。
This paper expounded four kinds of performances of ＂difficulties in fetching chem- istry knowledge＂： students couldn＇t fetch related knowledge timely, independently, accurately, comprehensively. The reasons were as following： students were unfamiliar with the knowledge contents, not clear to knowledge significance and knowledge links, their knowledge networks were not perfect, knowledge situations were unreal and knowledge was negative transfer and so on. Countermeasures to overcome the difficulties in fetching knowledge mainly included： optimi- zing teaching methods, paying attention to students＇ knowledge ＂output＂; creating real knowl- edge situations, promoting knowledge transfer; centering around core concepts, establishing knowledge links; clarifying the relationships between knowledge, perfecting knowledge net- works; carefully designing questions, strengthening self-monitoring, distinguishing between the new and the old, overcoming the interference of thinking set and so on.
