I taught Science (Biology, Physical Science, Life/Earth/Environmental...) for 36 yrs. Led the system in test scores the last 7 years. Football record 74-11. Coached 8 players that went to the NFL including one with a $40 million contract. (Melvin Ingram). I'm retired now. I was a teacher first....a salesman of sorts. Heard a lot of teachers say "You don't have to like me...". Wrong. I wouldn't buy a car from a salesman I didn't like. I used what I called "tags" for most of my lessons. A story that I would weave throughout my "walking around while talking/discussing" that made my students want to know what I knew. I noticed when I said "I remember one time" or the "other day I was" they would focus on the story. Would HATE to teach with laptops open on every desk now.
