转化思想是数学教学和学习中的重要思想,每个数学新知识都是知识发展和转化的结果。在教学新知识时,教师通常采用“发现转化”的方法将复杂问题转化为简单问题、将未解决的问题转化为已解决的问题,使学生能运用转化的思想去学习新知识、分析新问题。有幸听到张秀云老师在“全国小学数学(人教版)核心素养示范课观摩交流会”上的《一个数除以小数》一堂课,张老师在学生“发现转化”的基础上,根据学
Transformational thinking is an important idea in mathematics teaching and learning. Every new mathematical knowledge is the result of knowledge development and transformation. When teaching new knowledge, teachers usually adopt the method of “discovering transformation” to transform complex problem into simple problem, transform unresolved problem into solved problem, enable students to use transformation thinking to learn new knowledge, analyze New question Fortunate enough to hear Teacher Zhang Xiuyun at the “elementary school mathematics (PEP) core literacy demonstration class to observe the exchange meeting” on the “one number divided by a decimal” a lesson, teacher Zhang “found in the conversion” based on According to the school
