1 Data Based Astronomical Education and Citizen Science
Chenzhou Cui Shanshan Li, Dongwei Fan, with the whole China-VO team

2 A brief survey Please rise your hand if you are under 35+
Both VO and IVOA need more young individuals involved

5 Why Teach with Data? To teach with data usually requires curricular revision and a willingness to give up some control of the classroom. So, what's the upside? Below are six reasons most commonly cited by education experts: As an active learning strategy, teaching with data increases retention Working with data introduces students to problem-solving techniques for the messiness of real-world problems Teaching with data supports critical quantitative reasoning capacities Teaching with data can teach modeling skills Working with real data raises questions of ethical research Hands on research shifts attitudes toward science and quantitative analysis

6 For Resource Developers For Educators Resources
Carleton College Science Education Resource Center：Using Data in the Classroom (~ ) Engaging students in using data to address scientific questions has long been an integral aspect of science education. Today's information technology provides many new mechanisms for collecting, manipulating, and aggregating data. In addition, large on- line data repositories provide the opportunity for totally new kinds of student experiences. This site provides information and discussion for educators and resource developers interested in effective teaching methods and pedagogical approaches for using data in the classroom.

8 Great Reasons to Use Citizen Science in Class
Sense of Community and Place Recognition of Self Importance Understanding that Research isn’t Just for Scientists Reaching Different Types of Learners Development of Critical Thinking Skills Use of Multiple Skill Sets Application of the Scientific Method Meeting Next Generation and Common Core Teaching Standards By Karen McDonald at “

11 Popular Supernova Project，PSP, designed by Xingming Observatory and Chinese Virtual Observatory (China-VO) provides a platform for the public to make real astronomical discoveries. PSP is based on data from amateur astronomy observatory. It provides a new way of public education and citizen sciences, which effectively combine web technologies and astronomical learning together. PSP INTRODUCTION

browse online China-VO Data Center SUPERNOVA PSP发现的超新星侯选体上报及确认流程 1、PSP普通用户在PSP平台内上报给高级用户 2、PSP高级用户经过判断确认为疑似目标等待补拍（排除噪点、鬼影、已知恒星，已知超新星，已知小行星，已知变星，并根据经验确定值得补拍） 3、星明台望远镜当晚补拍确认或者第二晚补拍确认是疑似超新星目标 4、由高级用户负责写发现报告并上报IAU\CBAT，在TOCP网页贴出疑似坐标。并抄送超新星权威网页站长 TOCP： 5、等待专业台拍摄光谱确认，一般专业台拍摄光谱后会发布ATEL，目前IAU已经基本不给超新星发公报发布正式编号了，但在这之前大家都公认以拍摄到光谱确定的了类型作为是否是真实超新星的依据，所以目前只要有ATEL发布光谱就作为确认是一颗真实的超新星。 目前服役设备： 赤道仪：Paramount ME CCD： QHY9 望远镜： Celestron C14（口径356毫米，焦距3916毫米）+F6.9减焦镜 视场：19分（Dec)*25分(RA) 拍摄参数：曝光60秒，FITS格式，BIN=2,像素1792*1284 拍摄极限星等：约19.5等 Advanced user review Professional Observation And confirm Xingming Observatory In Xinjiang Report to IAU/CBAT TOCP Check the suspected target

Website: 也有一些人在这段时间内加入看图。 系统第一张图上传时间 2015年5月25日。 梳理改进流程，阅览图片。  2015年7月14日凌晨，PSP计划正处于测试期间，庞立凤于5:20，卫申权于6:43各自独立上报了一颗可疑的超新星目标。后由金彰伟验证为一颗3天前刚发现的已知超新星。

14 OVER 160 NEW REGISTERED USER ON THE FIRST DAY
如此大规模的用户爆发，对于系统的稳定性和承载能力是一次较大考验。 系统运行稳定 AUGUST 1ST, NEW REGISTERED USERS EXCEEDED 300.

15 FIRST SUSPECTED TARGET
September 12, 2015, Jiaming Liao submit a suspected target. Advanced user Jiangao Ruan verified and reported the target. FAILED TO CONFIRM DUE TO WEATHER 2015年9月12日上午，阮建高查验PSP项目可疑目标时，发现在廖家铭上报的目标非常可疑，后经排查，为真实目标，由徐智坚测量，阮建高上报。 可惜由于天气原因，没能及时有专业天文台进行观测确认。

16 FIRST SUPERNOVA CONFIRMED
In the morning of Oct. 3rd, jiaming Liao found another suspected object and this time it was confirm only 2 days later by astronomer from Yunnan Observatories and Tsinghua University.

17 TRADITIONAL MEDIA AND WEB PORTALS REPORT
再次进行媒体宣传，腾讯新闻弹窗 Tencent Technology , Netease News and so on…

18 SOCIAL MEDIA PROMOTION
中国虚拟天文台平台主要提供专业观测服务，所以很多为了公众天文台注册的用户 找不到PSP入口。 米琳莹 用户支持

19 9.14 new user 4993 (Single day registration) TOTAL USER NUMBER EXCEEDED 10,000 7.29 launch 到9月19日为止，每天都有上百人注册； 之后每天都有两位数的注册量。 我们出于谨慎，本身并没有对这一次的疑似发现进行宣传，耐心等待第一颗确认。 PSP系统经历了注册浪潮的考验，一天注册用户2000多人，至今已经注册用户上万，可喜的事，他们中有很多热爱科学，热情严谨的学生爱好者，这也是PSP项目的初衷，让更多的爱好天文爱好科学的年轻下一代能通过PSP平台参与到天文发现和天文研究中来，相信PSP项目会发展的更好~

21 INSPIRATION AND INNOVATION
COLLABORATION Collaboration between amateur astronomer and professional astronomy team. REAL DATA FOR PUBLIC SIMPLE NEWEST EDUCATION REAL SCIENCE RESULT Find a supernova event Study supernova spectrum INSPIRATION AND INNOVATION OF POPULAR SUPERNOVA PROJECT 简单：平台操作，发现方式。不需要了解复杂背景，产生原理。 最新的，具有时效性。专业稳定的平台使其成为可能。 教育：随着使用平台，开始对超新星和发现超新星有更多了解。（noise、ghost） 研究超新星，光谱可以告诉我们很多事。距离、超新星类型等……

22 OUTLOOK MORE PEOPLE Public (normal people, students, etc.)
Amateur astronomer Professional astronomy team IMPROVE TECHNOLOGIES Including more telescopes Improve data quality Improve the platform (English UI) GLOBAL COLLABORATION Public user and students Telescopes Projects OUTLOOK OF POPULAR SUPERNOVA PROJECT Expand by including more people and telescopes deepen professional cooperation 发现的超新星大部分距离较近
