My First Experience in Teaching Today, i have a new experience. I must teaching computer subject to the security in my company. And i have no preparation before because actually i just replace my senior place to teach. He must do something else so i must replace his place to teach his student ( in this situation his student is security ). My senior gave me some materials for teaching but i have no time to read it before because the time was limited. So i try to control my nervous and try to became a real teacher. It's my first time to teach him ( because every day my senior has one student ) so i don't have any idea to teach him. Actually i must teach him until one hour. But i don't know why before one hour, i have finish all materials for him. Maybe it just some minutes because my senior says "How can you teach him so fast?" But i just say that i know it's too fast but all materials that he gave to me has finish so i don't have any idea to develop that materials. And now i know that teaching people is not as easy as i think before. Sometimes i must prepare the materials, develop materials and make sure that everything i said to them was clear.
