摘要“地球表面的变化”是教科版《科学》五年级上册的第二单元,主要涉及课程标准中地球与宇宙科学领域内容。在教材出版之前,我们对五年级一个班的学生开展了试教活动。从试教整体过程来看,我们认为本单元的设计体现了课程标准要求和大单元结构的整体思路。教材中设计的探究活动、模型制作活动等符合五年级学生的认知特点及年龄特点,具有一定的趣味性、可操作性,在提高学生动手操作能力的同时,加深了他们对科学概念的理解,他们能够用学到的科学知识解释自然现象。

Abstract: "The change of the earth’s surface" is the second unit in the first volume of grade 5 of Science Edition, which mainly involves the content in the field of earth and cosmic Science in the curriculum standard. Before the publication of the textbook, we carried out trial teaching activities for students in a class in Grade 5. From the perspective of the overall process of trial teaching, we believe that the design of this unit reflects the requirements of curriculum standards and the overall idea of large unit structure. The inquiry activities and model making activities designed in the textbook are in line with the cognitive and age characteristics of grade 5 students, and have certain interest and operability. While improving students’ hands-on operation ability, they deepen their understanding of scientific concepts, and they can explain natural phenomena with their learned sci? entific knowledge.
