【摘要】：在科学课程学时容量有限而科学知识却呈爆炸式增长的背景下,“少而精”的教育理念被普遍接受,核心概念及核心概念学习进阶的研究也应运而生,日渐增多。围绕核心概念进行教学,有助于学生把握、建构学科的知识框架,更好的理解知识,也有助于学生知识的迁移运用及提高解决问题的能力。微软研究院设计开发的基于虚拟天文台理念和技术的虚拟望远镜——万维天文望远镜(WWT)由海量真实数据资源驱动,集交互性、合作性、探究性、情境性等优点于一身,现已成为天文教育中的一大利器。将天文学核心概念和WWT结合起来,运用于一直被中小学国家课程体系遗忘的天文学的教学中,能为天文学核心概念的教学提供借鉴,有助于WWT在天文教育中的推广。本文要解决的问题有两个：一是中小学天文学核心概念有哪些?二是WWT平台下基于核心概念的天文科学活动的设计流程是什么?为解决这两个问题,本文主要包括以下内容：第一,天文学核心概念的提炼。通过对我国科学、地理教材中天文学知识点和概念的分析与梳理,提炼出了核心概念。为验证其合理性,利用网络问卷调查平台对其进行调查,并分析调查结果,修改完善核心概念；第二,活动设计流程的建构。在分析一些基于核心概念的教学模式及教学设计流程的基础上,建构WWT平台下基于核心概念的天文科学活动设计流程,并制定活动评价的方案；第三,以该设计流程为指导,结合天文热点事件设计科学活动、学习单并制作WWT漫游作品,第四,实施科学活动并对其效果进行评价。经过研究,得出的结论如下：中小学天文学的内容可整合划分为日地月系统、太阳系、恒星、星系和宇宙4个主题,共8个核心概念,其中的7个核心概念得到了较好的认同。将WWT平台运用于科学活动中得到了大多数学生的认可,而且能激发学生学习的兴趣,活跃课堂气氛,值得推广及运用于教学中。
[Abstract]:Under the background of limited capacity of science courses and explosive growth of scientific knowledge, the educational concept of "little but fine" is generally accepted, and the study of core concepts and core concepts comes into being, increasing day by day. Teaching around the core concept is helpful for students to grasp, construct the knowledge frame of the subject, better understand the knowledge, and also help the students transfer and use the knowledge and improve the ability of solving problems. The virtual telescope-WWT-based virtual observatory concept and technology designed and developed by Microsoft Research Institute is driven by massive real data resources and combines the advantages of interactivity, cooperation, inquiry, situational, and so on. Now it has become a great weapon in astronomical education. Combining the core concept of astronomy with WWT is applied to the teaching of astronomy, which has been forgotten by the national curriculum system of primary and secondary schools. It can provide a reference for the teaching of the core concept of astronomy and contribute to the popularization of WWT in astronomical education. There are two problems to be solved in this paper: first, what are the core concepts of astronomy in primary and secondary schools? Second, what is the design process of astronomical science activities based on the core concept under WWT platform? In order to solve these two problems, this paper mainly includes the following contents: first, the extraction of the core concept of astronomy. By analyzing and combing the knowledge points and concepts of astronomy in Chinese science and geography teaching materials, the core concepts are abstracted. In order to verify its reasonableness, it is investigated by the network questionnaire survey platform, and the survey results are analyzed to improve the core concept. Secondly, the construction of the activity design process. On the basis of analyzing some teaching mode and teaching design flow based on core concept, this paper constructs the design process of astronomical science activity based on core concept under WWT platform, and formulates the project of activity evaluation. Thirdly, guided by the design process, Combined with astronomical hot events to design scientific activities, study sheet and make WWT roaming works. Fourth, carry out scientific activities and evaluate its effect. The main conclusions are as follows: the contents of astronomy in primary and secondary schools can be divided into four themes: solar system, stars, galaxies and cosmos. There are 8 core concepts, of which 7 core concepts are well recognized. The application of WWT platform in scientific activities has been recognized by most students, and it can stimulate students' interest in learning and activate classroom atmosphere. It is worth popularizing and applying in teaching.
