《小学教师专业标准(试行)》以及《中小学教师教育技术能力标准(试行)》都明确指出了教学设计的重要性,且被规划为一级指标,可见教学设计对教师而言尤为重要,是教师的不可或缺的能力。对于小学数学教师而言,部分教师的教学设计都存在诸多问题,从而影响数学教学的质量及教师自身的发展。将认知建模合理应用于小学数学教学中不失为一种较好的教学方式。一、认知建模应用于小学数学教学的原因分析当前,小学数学教学之中,往往缺乏“关于数学”知识, “Primary School Teachers Professional Standards (Trial)” and “primary and secondary school teachers' educational technology ability standards (Trial)” clearly pointed out the importance of instructional design, and is planned as a first-class indicators, shows that the teaching design is particularly important for teachers, Is an indispensable teacher's ability. For primary school mathematics teachers, some teachers have many problems in the instructional design, which will affect the quality of mathematics teaching and the development of teachers themselves. Applying cognitive modeling to elementary mathematics teaching is a good teaching method. First, the cognitive modeling applied to primary school mathematics teaching analysis At present, primary school mathematics teaching, often lack of “mathematics ” knowledge,
