These were some of the screenshots of how I intend to invite a response from the audience. There are 4 ways that the audience can send in their responses.
For academic purposes, it is best not to use the SMS function lest people incur any messaging costs, so I have opted for the web link option instead where the audience will access my poll webpage. The free version also does not seem to allow the SMS to be sent through. I have tried a few times and it failed.
Present the results in percentage form.
There is even a pluggable PowerPoint version of PollEverywhere where it allows you to login to PollEverywhere inside PowerPoint, add slides to view your poll results instantly. I am sure there will be more practical uses of this tool in time to come. If you know of any other better free online polling tools, please contact me.
