Teaching without speaking

The beginning of the presentation attracted much audience’s attention with beautiful music and interesting use of iceberg analogy, which showed the apparent features as skin color, gender, and dress, and at the same time the unapparent features as education. It went more interesting when the presenter asked the audience to close their eyes, and when everybody opened his eyes again, the presenter changed her outer appearance a little bit by wearing a headscarf. By doing this, she asked her audience to write some stereotypes that exist in society about women dressed like her, with the headscarf.
Such a beginning is very much engaging. Everybody was sort of convinced of the power of non-verbal communication because everybody got exactly what the presentation would be about. The presenter then asked the audience to do group work on the question: How could you non-verbally engage us here today on a topic like stereotyping, prejudice, or ethnocentrism?
There were five groups who presented stereotypes on marriage between man and woman and bias on gay marriage, names that bring prejudices and assumptions, and so forth. Every group showed successfully that non-verbal communication could be as much as or even more effective than verbal communication. People could refer to pictures, videos, and performances to achieve communication thus breaking down the wall to tables. Everyone just learned how to teach so effectively without speaking, not by listening to a lecture or a presentation, but by participating in it. It’s the best presentation I’ve ever been in.
