Considering that, I'm glad to talk about the topic of the difference of high school and college instructors. I will elaborate the topic from the following aspects. The first aspect, the students' learing mode is different. Students' passive learning is main in high school, while in college you can but study by yourself, nobody would supersive and urge you. The second aspect, I think the biggest change is the teaching mode and content. The teacher in high school always let us follow him and record every point, while the college instructors only focus on learning focus and skills. The third aspect is the relationship between teachers and students. In high school we could ask the teacher about problems we met in class, however once we finished the class in college, it was hard to see the teacher. I have only met the university's dean a few times. The relation ship in college between teachers and students is so alienated. These are my opinions on the difference between high school and college instructors.
