The idea of the tool is very simple, however, it represents a great up-to-date method of student involvement. Not only does it require the students to use technologies (webcam, microphone) for posting their responses but also it eliminates the need for paper worksheets and classroom time.
Setting up the site for the students is very easy. The teacher creates an account and makes the first room (grid) for posting the questions.
After the grid has been created, the teacher writes a question for the students to answer. In the example, I have written 3 questions for my students.
My students do not know yet what has been prepared for them. Tomorrow I am going to invite them to record and post their answers. If you are interested, I can write a follow-up to this post. Mention it in the comments below.
