学科领域知识与数学学习的知识表征研究

根据领域知识的结构特点对初中数学学科知识作出改编和重组,形成数学学科领域知识单元进行教学实验,以215名普通初中二年级学生为被试,通过自编问卷和深度访谈考察学科领域知识对知识表征的影响,并探讨了知识表征与数学学业成绩之间的关系。研究发现:(1)学科领域知识可以显著提高学生数学陈述性知识表征全面性和总体水平;(2)学科领域知识可以显著提高学生的程序性知识表征全面性、自动化、组织性和总体水平;(3)认知结构三要素、陈述性知识表征及程序性知识表征与数学成绩显著相关;(4)学优生的陈述性知识表征准确性、总体水平和程序性知识表征组织性、总体水平显著高于中等生和学困生。

The Research on the Knowledge Representation of Disciplinary Domain Knowledge and Mathematics Learning

Teaching experiments can be carried out with units of the disciplinary domain knowledge which are adapted and reorganized from the disciplinary knowledge in mathematics,on the basis of structural characteristics of domain knowledge.Some questionnaires and in-depth interviews which contained 215 students at second year at middle school were used to investigate the effect which is caused by disciplinary domain knowledge in knowledge representation and also did some research on the relationship between knowled...
