小学科学课程的总目标是要通过从3年级到6年级4年的科学教学活动来完成的。如果按7％-9％的课时比例测算,总计需约294-378个课时。按照传统的每节课1课时的方法计算,就是需要上294-378节课。这是以上课(包括室内上课和室外上课)的形式进行的教学活动时间。小学科学课程的总目标就是通过这样一堂课一堂课的教学活动来落实的,小学生的科学素养也主要是通过这样一堂课一堂课的科学学习培养起来的。因此,上好每一节 The primary goal of primary science curricula is to pass through four years of science teaching activities from Year 3 to Year 6. If calculated according to the proportion of 7% -9% of the class, a total of about 294-378 hours. According to the traditional method of calculating a class for each lesson, it is necessary to take 294-378 lessons. This is a teaching activity time in the form of classes (including indoor classes and outdoor classes). The primary objective of the primary science curriculum is implemented through the teaching activities of a lesson in which the scientific accomplishments of primary school students are also mainly cultivated through the scientific study of such a lesson. So, every good section
