Talk at students and they will forget. Involve them in their learning and they will remember. Excited teachers excite students. Create a stimulating learning environment with the use of visual analogy, storytelling, and magic illusion. There are few good answers, only good questions.
Students learn as they are tested, unfortunately.
Test for recall and the student will remember. Test for critical thinking and the student will learn to think critically. When you ask a question on television, wait at least 8-10 seconds for a response. There are only 60 minutes in a teaching hour on television. What we want a student to learn is more important than what we teach.
