Hi Amanda: These are great examples of what works for most teachers. Probably hundreds of examples could be given - the main thing is to keep the attention, even if that means something simple, or more active change up in the lesson, like moving from lcture to discussion, or from PPT and whiteboard to lab. Keeping students active also is helpful in keeping their attention. Facilitating their own learning is better then spoon feeding information. It's a fact, engaged students retain more essential information. Regards, Barry
