核心素养视域下的高考数学试题评析——以2020年3套高考理科数学全国卷为例

Research on National College Entrance Examination Mathematics Assessment fromthe Perspective of Core Literacy—Taking Three Sets of National College Entrance Examination(Science)Papers in 2020 for Example

基于《普通高中数学课程标准(2017年版)》,借鉴喻平、俞梦飞等人对数学学科核心素养评价框架的研究成果,构建了数学学科核心素养的测评框架,并对2020年3套高考理科数学全国卷中的学科核心素养及水平进行分析。研究发现,3套试卷关注现实情境,落实数学学科核心素养的考查;突出关键能力,强调数学应用;立足必备知识,注重融会贯通。为了发展学生的数学学科核心素养,高考命题要创设合适的情境,设计现实问题;教师需要把握数学课程内容主线,从“四基”“四能”着手制定教学目标,有针对性地培养学科核心素养。

Based on the General High School Mathematics Teaching Curriculum Standards(2017 Edition),through drawing lessons from Yu Ping and Yu Mengfei disciplines of mathematics,a framework for evaluating the core literacy of Mathematics has been constructed,and the core literacy and level are analyzed among the 3 sets of the national college entrance examination(science)papers in 2020.It is found that the three sets of college entrance examination papers mainly have three characteristics:focusing on the real situation and implementing the test of the core accomplishment of Mathematics,emphasizing core literacy and mathematical applications,basing on the necessary knowledge and paying attention to the mastery.In order to improve students’core literacy of Mathematics,proper context and real questions should be created,and teachers need to grasp the main line of Mathematics curriculumcontent,set teaching goals fromthe“four bases”and“four abilities”,and cultivate the core literacy of the subject in a targeted manner.
