Many people get nervous when speaking in front of crowds simply because it is out of their comfort zone. Teachers can use assignments to get students more comfortable with public speaking.
For example, write down easy topics for students to talk about and place them in a hat. Students can then draw a topic from the hat and then take 10 minutes to bounce ideas off of one another and prepare a few bullet points. Then allow them to talk about that topic for 2 minutes. Topics could include: what is the most important meal of the day or talk about your favorite childhood movie. Topics should stay simple and relate-able to everyone.
By creating a safe space for students to challenge themselves in this particular area, you have made it easier for them to develop this important skill. This is an easy way to not only advertise FBLA to non-members and possibilities of involvement to members, but to also build life skills in all students involved.
