《科学(3~6年级)课程标准》指出:以探究学习为核心是科学课程的基本理念,以探究为主的学习活动是学生学习科学的主要途径。在具体实施科学探究的过程中,必须发现和提出科学探究问题。在教学实践中,确定探究问题,既能决定一节课的内容,又能决定这节课的思路,从而直接影响到科学探究的展开。 “Science (Grades 3-6) Curriculum Standards” points out that taking inquiry-based learning as the core concept of science curricula and inquiry-based learning activities are the main ways for students to learn science. In the process of carrying out scientific inquiry, we must find out and propose scientific inquiry questions. In teaching practice, to determine the question of inquiry, not only can decide the content of a lesson, but also decide the idea of ​​this lesson, which will directly affect the expansion of scientific inquiry.
