数学教师学科理解:时代内涵、困境表征与提升路径OA

Understanding of the mathematics subject refers to teachers'structural understanding of mathematical knowledge,the logical presentation of mathematical thinking,and the intrinsic exploration of the educational mechanisms within the mathematics discipline.A mathematics teacher's understanding of the subject is a valuable prerequisite for effectively conducting mathematics teaching,a key factor in promoting students'acquisition of core mathematical competencies,and a necessity for enhancing teachers'professional development.Currently,issues such as structural deficiencies in understanding mathematical knowledge,the singularity in cultivating mathematical thinking and the"disembodied"deviation in educational practices are hindering the development of teachers'understanding of the mathematics subject.Therefore,it is necessary for teachers to pay attention to the history of the subject to deepen their understanding of the essence of mathematics;to focus on textbook research to enhance their understanding of mathematical content;and to engage in subject practices to deepen their methods of understanding mathematics.
