With the widespread of New Coronavirus in China, teachers are asked to support students learning online as all the universities have been shut down to prevent its spread. As a result, I introduced ZOOM to students as a platform to offer live teaching to students. I pasted the page of www.zoom.com.cn to the ¬†Website Accessibility eValuation Tool (WAVE) and found it is accessible. I then pasted this to Colorblind Web Page Filter and used the filter word of “Tritanopia” which describes a condition where a person cannot distinguish between blue and yellow colours. I was surprised as before this, I even did not have this kind of consciousness that there are people who are with this condition. The blue theme coulour of the ZOOM page turned to dark green.

Although the students I taught don’t have this condition, I should be aware of the fact that there are some who have this and therefore in my future teaching, I should be more careful in designing and sharing learning resources to students. E.g. If the coulour is essential in transmitting the information in the learning resources, what should I do alternatively to provide the information to those students with coulour blindness? In addition, are all the students able to access the online information? Do all of them have the adequate internet access and facilities to receive online class? This is especially a concern for us now as online live teaching is recommended by the government facing the COVID-19. Luckily, I have found that Zoom can record all the live teaching which then could be shared to students who can’t attend the live teaching when internet access is unstable to them. However, we still face the problem of teaching students with limit or now internet access. Moreover, we face the problem of organising online teaching at a definite time for those students in different time zones.¬†Thus, flexibility should be considered.
