Your students may not want to admit that they don't understand. Ask whether you've made your explanation clear instead, to take the pressure off them.
Share what you know with other teachers. If you're passionate about teaching, you'll want everyone to make use of the great information you have.
Outdoor learning enhances fact retention. The more senses you use, the more you'll remember.
Imagine that a new student has just come in. Can your class explain to them the concept you've just shared?
Use social networking such as Twitter; it's a great source of support for new teachers.
Take tips from cutting edge and effective teaching programs such as the excellent and online-video-based Khan Academy.

Not every student will be interested every minute. Try changing your tone of voice, moving around the room, and switching from lecturing occasionally.
Change up how you teach. Meaning teach in a visual, audio and hands on ways. When a student figures out how they learn they will start doing better.
