微课视频的设计策略决定了视频的质量,直接影响学生自主学习的效果。基于科学概念建构的微课视频,采用编码概念图、组织先行者、概念形成等教学策略,帮助学生准确理解概念的内涵与外延,掌握探究科学问题的逻辑与方法,发展高阶思维。为日后解决现实生活中的相关问题,自主开展科学探究活动打下知识、技能和思维能力基础。
Micro-video design strategy determines the video quality, a direct impact on the effectiveness of student learning. The micro-video based on the concept of science adopts such teaching strategies as coding concept map, forerunner and concept formation, helping students to understand the connotation and extension of concepts accurately, mastering the logic and methods of exploring scientific problems and developing higher-order thinking. In order to solve the related problems in real life in the future, we should conduct scientific inquiry activities and lay down the foundation of knowledge, skills and thinking ability.
