最近细读了两篇文章。一篇是南京师范大学数学科学学院教授喻平老师的《数学教学的三种水平及其理论分析》(见《课程·教材·教法》2012年01期)和浙江省金华市婺城区罗埠初中陈群颂老师的《也谈难点的突破》(见《中小学数学》(初中版)2012年1-2期),感受颇深。喻老师研究认为,数学教学可以分为三个层次:基本型教学、智慧型教学和创新型教学。三个层次所达到的教学效果和体现的教学功能由低到高依次提升。而基本型教学指教师在了解学生已有知识的基础上,在忠实于教材的前提下,根据教学目标制定教学计划和组织教学内容;教师在教学中能遵循数学教
Recently read two articles. One is the Nanjing Normal University School of Mathematical Sciences Professor Yu Ping teacher of “three levels of mathematical teaching and theoretical analysis” (see “Course Teaching materials,” 2012-01) and Jinhua City, Zhejiang Province Wucheng Luo port Junior high school teacher Chen Qun “also talk about difficult breakthroughs” (see “primary and secondary mathematics” (junior high school edition) 2012 1-2 period), deep feelings. Yu teachers believe that mathematics teaching can be divided into three levels: basic teaching, intelligent teaching and innovative teaching. The three levels of teaching effectiveness and embodied teaching function from low to high in turn improve. The basic type of teaching refers to the teachers to understand the existing knowledge of students, based on the faithful to the teaching materials under the premise of teaching plans based on teaching objectives and organize teaching content; teachers can follow the teaching of mathematics teaching
