Keep imagining something severe or serious.  Used to have the same problem and it was infectious. If I looked at a classmate of mine, they'd get this "uh oh, you're gonna make me laugh" look and I'd be in trouble with the teacher already... just look down at the floor until you compose yourself.

Be assertive, self-confident, and don't back down from anything.  Of course, this is on top of actually being a hard worker and producing positive results in your work.  I've noticed through experience that being funny also works, but make sure everyone's laughing with you - not at you.

Its always good to break the ice with a joke or witty remark. Dont worry about being nervous and shaky, if you are doing a speech for school everyone knows what you feel like. Be your natural self - dont try to be extremely proper or news anchorman like. Just be yourself, study what you wanna say, so you dont have to use to many notes. Use gestures and mimik where appropriate.

I have been like this for a while now ,someone told me the worst thing you can do is worry about it so I don't.Keep writing things down and being organised and enjoy your life and have a laugh at yourself when you do something silly.There's worse things could be wrong with you.

Sit in the front row, this will help you focus on the teacher and the material and not what is going on around you. This has worked well for me. If you still find yourself getting distracted, try taking notes and NO DOODLING! If all else fails, tape record your lectures for reference later on (you can buy a digital recorder for around $40). If it is a very long class, it will be impossible to pay attention for the entire lecture- talk to your teacher about taking 5 minute breaks when the class seems to be getting restless. Good luck!

If you are prepared, then you have nothing to worry about.  Also, you may be so fearful of making a mistake that you obsess over every little thing.  I have found after almost 30 years of teaching that you just have to be flexible and have a sense of humor.  If things mess up, laugh and go on.  Your audience will appreciate that more than you getting upset.  Once you are prepared, get out, do something else.  Take a walk, visit with friends, swim, watch a movie .... relax your mind.  Take deep breaths.

One of the funniest skits I ever saw was some P.E. teachers who did an exercise routine, with the more petite teachers straddling the taller teachers who were lying down, so that the legs of the reclined teachers looked like the legs of the straddlers. Use a blanket to cover up the top half of the inclined teachers and the thighs of the straddlers (kneeling). I don't know what your subject is, but if you are trying to entertain as well as teach, this could work. The audience thought it was funny when the legs didn't do what the top teachers tried to make them do. Another possibility is to do a skit with puppets, if you are working with young children.

I really don't think you really found it funny..it is an extreme situation and we tend to laugh....it's away to relax...it's a nervous laugh.\nTry not to do it so the teacher sees you or you'll be the next one out!\nA little cough usually disguises a laugh.

1) Don't read off your notes (or Powerpoint presentation or overhead transparency)\n2) Don't dance around or ring your hands or play with your hair\n3) Talk loudly and clearly (without shouting) and make sure your voice doesn't go too high-pitched\n4) Make sure you look left, right and straight ahead for about 3 seconds each (otherwise people won't feel included and will start chatting amongst themselves, which will make you even more nervous)\n\nThese are the basic guidelines I give my students.\n\nGood luck.

I don't really want to sit on the toilet and laugh but I do want to laugh.

If you're being laughed at, you should talk to your parents or teachers about it.  Really, the internet is not the best place to look for answers about these sorts of things.  Hopefully, you know an adult who you can trust with whom you can talk about these sorts of things.  That's a much healthier alternative to asking people online who you don't know.

Pick out a single person in your audience or classroom and look into their eyes, as if that one person is the only one you're talking to.\n\nThen, just move your eyes around the room as if you were talking to EVERYONE BUT YOU'RE NOT.\n\nPretend it's just you and your friend talking and HE is just LISTENING!\n\nThat's what I used to do and it worked great for me.  Maybe it will work for you!  Try it and see!\n\nAlso it's important to have fun with it and enjoy it!\nSaying something funny always helps break the tention.  I used to do that all the time.\n\nTry it!...AND.....TAKE A DEEP BREATH AND ENJOY HAVING CONTROL OF THE ROOM!

Do something and increase your self confidence.When talking don't too fast take your time and let the words come out.Those who laugh at you aren't worthy of being called friends.I know I had this problem too,still have it but not so evident.Hope this helps.

Have a good attitude. Most teachers have great ideas that cannot fly without students being willing to go on the journey.  Nobody can have fun if they are constantly being corrected or yelled at nor can a teacher be fun if they are always weary of behavior.
