初中数学拓展性课程开发的路径及案例研究

Development Path and Case Study of Mathematics Enrichment Curriculum in Junior Middle School

针对拓展性课程的选择性、层次性、操作性、丰富性等特征,拓展性课程开发应坚持学为中心的理念,并遵循以下开发原则:围绕立德树人强化育人目标;基于数学学科构建课程体系;生活内容数学化,实现教育内容课程化;渗透数学思想实现核心素养校本化。在此基础上,提出拓展性课程开发的六条路径:游戏激趣,激发数学学习兴趣;文化熏陶,丰富数学教育内涵;实验探究,提升数学探究能力;联系生活,培养数学建模思想;挖掘隐性知识,渗透数学思想;适度拓展基础知识,开阔数学视野。

In the view of the selectivity,hierarchy,maneuverability,richness and other characteristics of the enrichment curriculum,enrichment curriculum development should adhere to the idea of centering on learners,and the development principles are as follows:strengthening the goal of educating people based on promoting morality and nuturing talents;constructing the course system based on the mathematics subject;realizing the mathematics from the life and the curriculum of the educational content;infiltrating mathematical thought to realize the school-based key competency.On the basis of this,there are six paths to enrich curriculum development:stimulating interest in mathematics learning through games;cultural historical edification to enrich the connotation of mathematics education;experimental inquiry,improving the ability of mathematical inquiry;connecting life and cultivating mathematical modeling thought;excavating explicit knowledge and infiltrating mathematical thought;expanding the basic knowledge and broadening the view of mathematics.
