Teachers that make me angry
One thing that I find very annoying is listening to teachers who no matter what is expected of them, keep failing to use their common sense and preparing things in advance. When The Thai head of the department asks why, their answer is because they haven't been told or shown, even when they state they have years of experience. Not only that but here are other teachers in the staff room willing and happy to show or help them. And then there are the so-called teachers assigned to say, teach conversation, but continue to just offer worksheets and when doing exams or tests, knowing that they may have hundreds of students, wait until the last week to offer up grades that really don't reflect the student true abilities.
