小学科学核心概念的学习进阶研究——以“地球系统”为例

A Study on the Progression of Learning Core Concepts in Elementary School Science:Taking"Earth System"as an Example

帮助学生建立核心概念体系是科学教育的核心目标,科学安排学习进阶是实现这一目标的重要途径。以“地球系统”核心概念为载体,初步构建学习进阶模型。选取S小学二至六年级200名学生进行测试,运用正确率-集中度二因素分析法进行修正,构建出“地球系统”核心概念学习进阶全景图。基于此,从教学目标导向、教师能力提升、教材创新应用以及数智赋能教学四个方面提出教学建议,以期促进学习进阶理念在小学科学教学中的有效融入。

To help students establish a core conceptual system is the core goal of science education,and the scientific arrangement of learning progression is an important way to achieve this goal.Based on the core concept of"Earth System",the preliminary model of learning progression was constructed.Selected 200 students in grades 2 to 6 of S Primary School were tested and corrected using the two-factor analysis of correctness-concentration to construct a panorama of the learning progression of the core concepts of the"Earth system".The study proposed teaching suggestions from four aspects:teaching goal orientation,teacher competence enhancement,innovative application of teaching materials,and numeracy-enabled teaching,with a view to promoting the effective integration of the concept of learning progression in primary science teaching.
