高中生数学学科关键能力测评指标体系的构建

数学学科关键能力是基于学生数学学科核心素养的外显能力,研究核心素养视域下的数学学科关键能力测评指标体系是促进数学核心素养落地生根的重要保障。研究以STEAM教育理论、PISA和TIMSS数学素养测评框架、高中数学课程标准要求为基础,运用专家咨询法与层次分析法,构建了高中生数学学科关键能力测评指标体系,具体涵盖数学观察、数学思考、数学表达3个一级指标,每个一级指标包括4个二级指标,得到表达式为:数学学科关键能力 = 0.165*数学观察 + 0.249*数学思考 + 0.586*数学表达,教师可以根据该测评体系,指导学生提升数学学科关键能力。The key ability of mathematics is the explicit ability based on the core quality of mathematics. To study the evaluation index system of the key ability of mathematics from the perspective of the core quality is an important guarantee to promote the implementation of the core quality of mathematics. Based on STEAM education theory, PISA and TIMSS mathematical literacy assessment framework, and senior high school mathematics curriculum standard requirements, the research uses expert consultation method and analytic hierarchy process to build a key ability assessment index system for senior high school mathematics, which specifically covers three first-level indicators: mathematical observation, mathematical thinking and mathematical expression. Each first-level indicator includes 4 second-level indicators, and the expression is as follows: Key ability of mathematics subject = 0.165*mathematical observation + 0.249*mathematical thinking + 0.586*mathematical expression. Teachers can guide students to improve the key ability of mathematics subject according to the evaluation system.

小学数学学科关键能力的培育模式研究

小学数学是最为关键的教学基础，因此提升当前小学数学的学科关键能力可以让学生自身的数学能力得到良好的培养并获得坚实的基础。因此小学数学的学科能力的培育就成为了我们教学的重点。

小学数学学科关键能力的培育策略

儿童核心素养的培养是小学数学课程实施的重要目标,而核心素养培育中数学学科关键能力的培养是重点。小学数学学科六大关键能力包括数学理解与数学表征能力、数学建模能力、数学逻辑思维能力、数学问题解决能力、数学推理与论证能力、数学交流与表达能力。在小学数学教学过程中,以学科核心知识为中介,以数学问题解决为线索,以数学建模为路径,以思维与认知发展为旨归,可以提升学生的数学关键能力。
