 Okay. My name is Yen Fu Chen. I'm working at the Center for Digital Learnings in National Eden University. Today we want to share some unused opinions. The subject is increasing the usage of open courseware during the COVID-19 epidemic. This study was done by Professor Da Yong Zhu, Professor Yun Che Lin and me. Let me present our study today. This light talk will cover the NIU OCW's background, this research methodology, and NIU's open course resources, data analysis. Finally, we will talk about the summary and suggestions from the NIU's case. First, let's introduce the OCW at NIU. NIU built the site of OCW in 2013 and set up the virtual studio in 2015. From 2013 to now, NIU keeps produced the digital courses at OCW and MOOCs site. In current NIU's OCW site, the lectures compile the course material like text, sounds, video to be the OCW course content, then publish at the NIU OCW site. The audience over the world will visit the OCW courses, but the mode is only unidirectional. The audience cannot interact with the lecturers and another audience. As everyone knows, in 2020, all of us faced the COVID-19. The entire world has undergone tremendous changes. The lifestyles were changed. For example, increasing the social distancing and no gatherings. Also, most of countries closed the border. So, like this year, OE Global 2020 conference changed to the online mode. All of us meet each other online. Next, the OCWs of NIU didn't publish any new curriculum resources from 2017. However, compared with the data from January to June 2020 and the same periods in previous years, they are significant change. So, we decided to use the case study, event study, and surveyed to understand those changes. After we collected the traffic of NIU's OCW sites and analyzed, then we found the traffic has declined from 2018 to 2019. But the number of the website visits has reversed growth trend from January to June 2020 with 10.45 percent rate. The growth rates of the new users had increased from 2.64 percent to 11.33 percent. This made in case that the COVID-19 has affected the number of OCW usage. We also collected the data of the MOOCs site of NIU, but the data is count annually. So, from the chart, you cannot see the number of 2020. So, will the traffic of MOOCs site goes up or going down? They are up straight in the chart. Next year, we will know the answer and we will share the information for everyone. We also analyzed the NIU's e-learning and IRS platforms. We found the usage is upward trend during 2020 January to June. From those above statistics, we realized that when they are more external factors happen, then the demand of e-learning and its applications is growing repeatedly. So, we summarized as below. OCW can help slow down the spread of the COVID-19. Effective advanced deployment of OCW and e-learning can reduce the impact of external factors on teaching and learning. Also, if we can provide a more diverse learning environment and a more flexible teaching mode, it will be more conducive to the learning's effectiveness of the students. Also, after the first pick of COVID-19, NIU's teams believe that crisis is the turning point. So, we will focus on the NIU's brandings and quality of the course and the shortness of the knowledge and content, target audience and leach market. Also, we will correct more user feedback. We should perform active activities to create two ways, communications for connecting users for future production of NIU's OCW. So, for COVID-19, Taiwan can help. For open educations, NIU can help as well. If you are interested in more information about NIU OCW, please visit E-Poster. The number is 338. My talk finished here. So, thanks for your listening.
