在学校党支部的领导下,在数学教研组和师院数学教学法教研组的老师的集体帮助下,我们在检查了数学教学中存在的少慢差费的基础上,对加速提高教学质量作了一些尝试。我们举行了一堂数学“双高”公开課,将立体几何中二面角,平面互相垂直的关系这一单元由过去需要九小时才能教完的教材,集中在一 Under the leadership of the school party branch, with the help of teachers in the mathematics teaching and research group and the teaching and research group of the mathematics teaching method in the teacher’s school, we have made some improvements in accelerating the quality of teaching on the basis of examining the existence of a small fee. try. We held an open class in mathematics “double heights”, which combines the dihedral and plane perpendicular relations in this three-dimensional geometry from a textbook that used to take nine hours to complete.
