【摘 要】“核心素养”一词一经提出便在学校教育领域掀起了巨大浪潮,我国优秀的教育专家与一线教师也综合分析了核心素养结构下各学科的学科素养内涵,以便通过学科素养教学改革逐步发展学生的核心素养,真正为学生的长远发展做准备。为此,高中数学教师也应及时树立核心素养改革理念,积极组织解题探究活动,综合性地发展学生的数学思维能力、改善学生思维品质,让学生既能有效解题,也能通过解题探究学会数学。本文将结合笔者的教学经验,分析核心素养导向下教师应该如何优化解题探究活动。

【Abstract】The word "core literacy" was proposed and caused a huge wave in the field of school education, our country excellent education experts and first-line teachers also analyzed core literacy structure under the interdisciplinary science literacy connotation, so that through the core of the reform gradual development of the students' science literacy teaching literacy, really prepare for the long-term development of students. Therefore, high school mathematics teachers should also establish the concept of core accomplishment reform in a timely manner, actively organize problem solving and inquiry activities, comprehensively develop students' mathematical thinking ability and improve their thinking quality, so that students can both effectively solve problems and learn mathematics through problem solving and inquiry. This paper will combine the author's teaching experience to analyze how teachers should optimize problem solving and inquiry activities under the guidance of core literacy.

解题,即解决问题,而问题在高中数学教学中的重要性是不言而喻的。从数学学习的目的来看,学好数学知识除了要帮助学生走进更优秀的学府接受专业教育之外,也要确保学生能够准确发现现实生活中的数学问题,并能通过数学抽象、数学建模活动解决问题。因此,高中数学教师要围绕核心素养内涵来组织问题解决活动,以便培养学生的核心素养。
一、整理生活材料,从感性展开抽象推导
从数学学科的核心素养体系来看,“数学抽象”素养的基础教学目的比较突出,因为高中生本身就需要通过数学抽象来生成数学认知,将现实问题转化为数学问题,通过简化、推导、猜想与证实活动解决相关问题,理解数学道理。
