Time-Saving Teacher Tip-Controversy

Teaching controversial topics can be nerve-racking. You wonder who you’re going to set off by mentioning the word “evolution” or “Pangaea”. You don’t want to upset anyone, but your students need to understand the topic well enough to make up their own minds. That’s when you approach it in the 3rd person. Present in a voice and tone that says, “Students, this is what an evolutionary scientist believes”, and then go into the topic. You’ve left yourself completely out of it and just presented the facts.

Instead of another forgettable lecture, how about an activity in which every student participates and later recalls the kinds of rocks, and how they change from one to another.
