In other words, theory and practice come together in such a study. Action research puts ideas into practice for the purpose of self-improvement and increasing knowledge about curriculum, teaching, and learning. Since the main aim of action research is to improve instruction, it is preferable that classroom teachers be directly involved in this process. With the growing interest in the learner and learning process, teachers have become more interested in practical solutions to problems. There are different ways of collecting data about instruction.
Teachers can video or audio tape their lessons and transcribe afterwards.
They can also keep journals or detailed diaries for each one of the students and for what they have been doing, and keep track of what has been done in the classroom. Carrying out observations and administering surveys and questionnaires are other possible means of collecting data about the teaching learning process. Keeping journals not only helps the instructor observe student performance continuously, but gives the opportunity to question one's own teaching. One can write down one's feelings, reflections, plans, and observations. It is important that teachers write in their journal regularly.
