九年义务教育小学自然教学大纲明确提出:自然是义务教育小学阶段的一门重要基础学科,担负着向学生进行科学启蒙教育的任务,以至提高全民族的科学文化素质。 低年级学生刚上自然课,知识面窄,经验少,不知该怎样观察,怎样讨论,怎样进行各种操作。因此,教师在教学中必须对学生进行逐项训练,使之形成良好的习惯,为今后的学习奠定基础。 The nine-year compulsory education primary school nature syllabus clearly states: Nature is an important basic discipline in the compulsory education primary school stage, shouldering the task of educating students in science and enhancing the scientific and cultural qualities of the entire nation. Junior students just started the nature class, narrow knowledge, less experience, I do not know how to observe, how to discuss, how to carry out various operations. Therefore, teachers in teaching must be carried out one by one for students training, making it a good habit, lay the foundation for future learning.
