生态课堂是目前小学数学教学提出的一个全新理念,是让数学课堂由“教”向“学”转变的重要举措,它的基本特征就是让学生能够在数学课堂上自主学习,让学生有自主的思维时空,在课堂上自主合作,进行“学生教学生”的练习,从而促进学生在课堂上可以更好地生成。下面,笔者就结合苏教版小学数学五年级上册《小数加法和减法》的教学,谈一谈如何打造生态数学课堂,促进学生在课堂上的生成。(教材情境图见右图) Ecological classroom is a new idea put forward by elementary school mathematics teaching at present. It is an important measure to change mathematics classroom from “teaching ” to “learning ”. Its basic characteristic is to enable students to study independently in mathematics class, Students have independent thinking space and time, in the classroom co-autonomy, “student teaching students ” practice, thereby promoting students in the classroom can be better generated. Next, I will combine the Supian version of elementary school mathematics grade five “decimal addition and subtraction” teaching, talk about how to build ecological mathematics classroom, to promote students in the classroom.
