义务教育课程标准(2011版)把原来的“双基”目标扩展为“四基”目标,在总目标中提出了“四基”(基本知识、基本技能、基本思想、基本活动经验),“四能”(发现问题、提出问题、分析问题及解决问题的能力),数学思维方式及数学情感态度的目标要求[1].这些目标相互联系,错综复杂,怎样在具体的教学中整体有效地达成这些目标,这是值得研究的问题.1整体有效达成目标的基本平台——数学认知活动1.1数学活动是实现数学核心教育价值的基本平台
The compulsory education curriculum standard (version 2011) expands the original “double base” target to the “four base” target and proposes “four bases” (basic knowledge, basic skills, basic ideas, Basic activities experience), “four energy” (the ability to discover problems, ask questions, analyze problems and solve problems), mathematical thinking mode and mathematical emotional attitude [1] .These goals are interrelated and intricate, Achieving these goals in a concrete teaching as a whole is an issue that deserves to be studied.1 The Basic Platform for Effectively Achieving the Goal as a Whole -Mathematical Cognitive Activities 1.1 Mathematical Activity is the Basic Platform to Realize the Core Educational Value of Mathematics
