数学知识的学习源于生活,最终回归于生活。学生丰富的日常生活经验是他们学习数学新知的起点,也是教师展开数学新知教学的起点。为此,在教学“不含小括号四则混合运算”时,我们教师应关注学生已有的生活经验和认知基础,组织学生开展相关的数学活动,帮助学生体验与建构新知。一、回归学生的“日常生活”学生在生活中已经积累了一些关于数学的原始、初步的经验。对于数学知识的认识和理解,有时需要具有丰富的生活经验背景,让生活经验和数学经验
Learning of mathematical knowledge from life, and ultimately return to life. Students rich experience in daily life is the starting point for them to learn new knowledge of mathematics, but also the starting point for teachers to start new teaching of mathematics. For this reason, teachers should pay attention to students’ existing life experience and cognitive foundation when teaching “without parentheses”, and organize students to carry out relevant mathematical activities to help students to experience and construct new knowledge. First, return to the students “daily life ” students in life has accumulated some original, preliminary experience on mathematics. Understanding and understanding of mathematical knowledge sometimes requires a rich background of life experiences to make life experience and math experience
