Why does my World History teacher suck at teaching?

Anonymous
She puts on a powerpoint presentation, reads directly from it word by word, then gives us worksheets then a test. That's it. She doesn't know sht of what she's teaching. She still thinks Czechoslovakia is still one country (it's now two). A student asked her to explain bce, bc, and ad. She promised to do it and has never done so. She promised 3 months ago. My humanities teacher, last year, just needed a marker and he wrote the notes by himself on the board. Casually. He didn't need sheets of paper, or a powerpoint. Cause he KNEW what he was teaching. He didn't need to go online to learn about WWI.

If somebody randomly asked her to explain WWI, she'll just say, "A bunch of countries in Europe didn't like each other. So they fought. A lot of people died, then WW2 happened." That's fine for an everyday person. But a world history teacher who can't name 1 battle of WW1 OR 2? No.
