The article talks about how a teacher's patience affects how well students learn in a writing class. The researchers studied a teacher in a Chinese university who used a method called assessment for learning. They found that when students didn't meet the teacher's expectations, the teacher's patience helped them keep using this method. But sometimes, the teacher's patience got weaker, which made the method less effective. The study shows that teacher patience is really important for helping students learn better. It suggests that teachers should learn how to be patient so they can handle the challenges of teaching and help students succeed.
