It's just her opinion on teaching. I don't think it was directed to you really maybe just an overall thing? Try telling her how it makes you feel? Alot of students do better with fun learning and it helps their little minds hold info. Do what you feel is right!!

You could be overthinking just a little. Some people think school is just to learn and that's it, while others like to make school a comfortable, fun learning environment. She may not have meant any harm by what she said.
