近来,有幸聆听特级教师徐斌教学苏教版三年级《数学》“画线段图解决问题”一课,欣赏到徐斌老师充满无痕魅力的数学课堂教学,在不露痕迹中,教师教得自然,学生学得顺畅。课堂教学把学生已有的认知与要探求的未知进行无缝对接,从具象有形到抽象无形的渐进中,学生思维拔节、认识提升,从而不仅建构了完善的数学认知结构,也发展了数学综合素养。一、赏析数学无痕教育的精彩片断【片段】徐斌老师在教学“画线段图解决问题”谈话导入时,课
Recently, I was fortunate enough to listen to a class of top grade teachers Xu Bin Sujiao version of the third grade “Mathematics” “Draw line drawings to solve the problem ” class, enjoy Xu Bin teacher full of traceless charm of mathematics classroom teaching, without notice, teachers Teach it natural, students learn smoothly. In classroom teaching, the existing cognition of students is seamlessly connected with the unknown to be explored. From the concrete form to the abstract and invisible gradual progress, the students’ thinking is more important and the knowledge is improved, so that not only the perfect mathematical cognitive structure but also the Mathematical comprehensive literacy. First, the appreciation of mathematics traceless wonderful piece of education [clip] Xu Bin teacher in teaching “to draw a line diagram to solve the problem ” conversation into the class
