小学低年级学生年龄小,富有好奇心、好动、喜欢模仿,具有直观、具体、形象等思维特点。高年级学生已初步形成了一定的学习态度,并且随着主体意识的觉醒,自我意识、自我主张、自我控制能力进一步加强。如何巧妙利用低年级学生的好奇心、高年级学生的自我意识,促使其融入数学课堂,提高学习效率?从情境教学入手,分析低年级与高年级两个不同年段的数学课堂。 Lower primary school students are young, curious, active, like to imitate, with intuitive, specific, image and other thinking features. Senior students have initially formed a certain learning attitude, and with the awakening of subjective consciousness, self-awareness, self-assertion and self-control ability have been further strengthened. How to skillfully use the curiosity of the junior students and the self-awareness of the senior students to promote them into the mathematics classroom and improve their learning efficiency? Starting with the situational teaching, the mathematics classrooms are analyzed in two different years: lower grade and upper grade.
