share (in the) responsibility (for)
Although students' learning is inextricably linked with teachers, it is unreasonable and harsh to put all the responsibilities on teachers.
Teachers who can't teach
"There are no students who can't teach well, only teachers who can't teach well". Because of the "misinterpretation" and "out of context" of later generations, many parents who don't understand education think that teachers can teach their children well after sending them to school without asking.
educational environment
In the current educational environment, it is not objective and irrational to put this sentence directly on the teacher.
