小学科学涉及的知识主要有三个领域:生命世界、物质世界、地球和宇宙。而“生命世界”的一草一木、虫鱼鸟兽伴随着学生的童年生活,他们对此充满了神秘感和好奇心,为学生提供了许多培养科学素养的机会。在这一领域的探究中,学生将认识不同种类的生物,收集数据、参与实证,建构和理解相关科学概念,提升对生命本质的认识。但纵观“生命世界”的教学,还存在着较多问题:如动植物都有一定的生命周期,而教材的编排并不一定与之对应, There are three main areas of knowledge involved in primary science: the life world, the material world, the earth and the universe. And the “world of life” grass and wood, insects fish and birds accompanied by the students’ childhood, they are full of mystery and curiosity, providing students with many opportunities for scientific literacy. In this field of inquiry, students will recognize different kinds of living things, collect data, participate in positivism, construct and understand related scientific concepts, and enhance their understanding of the nature of life. However, if we look at the teaching of “life world”, there are still many problems. For example, animals and plants have certain life cycles, but the arrangement of teaching materials does not necessarily correspond to them.
