ACTION RESEARH

Action Research or in Indonesian we said "PTK", is an activity that is done by teacher to find a better way in class studying process. So the teacher has to be a researcher. Some people said that action research has to be done with other teachers as co-researcher, but in my opinion, the teacher alone can do research by himself. A teacher can use his diary to write anything that happens in the class. A teacher can use camera to record all activities in the class. A teacher can use questioner or written test which is filled by students. Those are the things that a teacher can use to make some research in order to improve his students' ability, alone by himself.
