基于大概念的小学科学教学实践研究

Practical Research on Primary School Science Teaching Based on Big Concept

2017年修订的《义务教育小学科学课程标准》对大概念理念下的小学科学教学进行了强调。在小学科学教学中渗透科学大概念,应在横向拓展中建构知识体系,在纵向深入中建构科学方法,在螺旋递进中建构层级概念,以帮助学生广泛、系统地吸纳知识,快速有效地运用知识,建立一个完整的世界理解与认知,初步形成科学态度、掌握科学方法、理解科学精神,构建出一个健康、协调发展的基础。

The newly-revised Outlines in 2017 emphasize primary school science teaching in the idea of big concepts. To realize the penetration of big concepts into science teaching, teachers should construct the knowledge system in cross-sectional expansion, construct scientific methods in longitudinal depth, and construct stratum concepts in spiral progress, so that teachers can help students absorb knowledge extensively and systematically, apply knowledge swiftly and effectively, and create a complete understanding and cognition. Besides, students can preliminarily form their scientific attitudes, grasp scientific methods, understand scientific spirits, and eventually build a healthy and harmonious foundation of development.
