教学是一门艺术,一堂高效的数学课是一场学生与教师融入角色的精彩艺术创作,它既是生动的,又是深刻的。要上得生动,教师就必须了解学生,读懂学生,要善于在抽象的数学知识与学生的认知水平之间架设桥梁。要上得深刻,不仅需要教师具有精湛的教学技能,还必须读懂数学,掌握教育教学理论,在确保学生主体地位的同时,充分发挥教师的主导作用,认真备课、吃透教材、精心预设,将工夫花在新 Teaching is an art. An efficient mathematics lesson is a wonderful artistic creation in which students and teachers are integrated into the role. It is both vivid and profound. To be vivid, teachers must understand the students, understand the students, and be good at establishing a bridge between the abstract mathematical knowledge and the students’ cognitive level. To be profound, not only requires teachers with superb teaching skills, but also must understand mathematics, master education and teaching theory, while ensuring the dominant position of students at the same time, give full play to the leading role of teachers, conscientiously prepare lessons, thoroughly through teaching materials, carefully preset, Will spend time in the new
