Set a good example. Check your appearance
Make those around you comfortable. Hypothetically speaking you should be the one facing the sun.
Know your subject – be prepared
Use your reference material. Don’t hesitate to refer to a book, a magazine, an article etc.
Talk to the whole group. Look them straight in the eye. Speak clearly and loud enough.
KISMIF: Keep it simple, make it fun. Explain fully but briefly.
Encourage questions – allow time for, and welcome questions.
Never criticize in public. Don’t scold, keep an open mind.
Discuss problems with leaders first.
Forget how good you are – “We “ is better than “I”.
Don’t forget…. let God lead your path.
