Interesting conversation with a friend today! They were telling a story about a teacher they had in high school (they were schooled in America) who they thought didn’t have enough knowledge of the course content. They said one time a student asked in class if the new poet they were about to study, was still alive. The teacher said no they’ve passed. The student pointed out the textbook said they were still alive and well and in their 70’s. And this was the truth. The teacher passed it off and said he got mixed up. AIBU to think it could have been a mistake and the teacher might have been new to teaching that topic etc. Or is it a serious lack of content knowledge/ lack of preparation. Just curious on people’s thoughts
