科学探究始于细致的观察,通过观察,能够获得对客观世界的各种事物和现象的认识。对于三年级学生来说,由于缺乏这方面的直接体验,观察往往停留在单纯用眼睛看的阶段上。科学教材(教育科学出版社)起始单元近似于在引导一个初学科学观察的孩子,通过选择一棵树作为观察对象,形成对科学观察的感性认识。 Scientific inquiry begins with careful observation, through which observations can be made to gain insight into the various things and phenomena in the objective world. For third graders, observation often stays in a purely eye-catching stage due to a lack of direct experience in this area. The science textbook (Educational Science Press) starts with a unit similar to a child who guides a beginner science observation by selecting a tree as the object of observation and forming a perceptual awareness of scientific observation.
