Research On The Design And Practice Of Astronomical Science Activity Based On The Core Concepts On The WWT Platform

On the background of limited capacity of science courses and the explosive growth of science knowledge, the concept of "Less is More" was generally accepted, the research of the core concepts and its learning progressions emerges as the time requires as well, increasing day by day. Teaching by revolving around the core concepts is more helpful for students to grasp and construct the knowledge framework with better understanding, and it will contribute to knowledge migration, the utilization and the ability of solving problem. The World Wide Telescope (WWT), a virtual telescope that designed and developed by Microsoft Research based on the concept and technology of virtual observatory, actuated by amount of real data resources, which is rolled up lots of good qualities as interaction, cooperative, inquiry and situationality into one, is already becoming a big sharp weapon of astronomy education. Combining this core concepts and WWT to apply to the astronomy education, which was forgotten by the course system of middle and primary school all the time, can provide reference for the teaching of core concepts and help the promotion of WWT to the astronomy education.There are two problems have to be solved in this thesis:The first one is what are the astronomical core concepts of middle and primary school? The second one is what is the design process of astronomical science activities based on the core concepts on WWT platform?To solve these two problems, this thesis contains the contents as the follows:Firstly, the extraction of astronomical core concepts, which is refined by analyzing and carding the astronomical knowledge point and concept of our sciences and geography teaching material. To verify its rationality, a survey has to be conducted by network questionnaire system and analyzed the results for improving the core concepts. Secondly, the design process construction of activity. On the basis of analyzing the teaching mode or teaching design process of core concepts, to construct the design process of astronomical science activities that made on account of core concepts on WWT platform and conducted the plan of activity evaluation. Thirdly, guided by this design process and combined with the astronomical hot events, to design science activity, worksheets and make the WWT roaming works. Fourthly, conducting science activity and estimating its effect.Reaching the following conclusions after doing research:The astronomy contents of middle and primary school can be divided into four integration subjects as the Sun-Earth-Moon system, solar system, fixed star, galaxies and the universe, which are eight core concepts in all, seven of them received better recognition. The application of WWT in the science activity gained acceptance of the majority of students, motivated students’ learning interest and active classroom atmosphere, which is worth popularizing and utilizing to teaching.
