In this paper, I will examine advanced level learners' thinking process from their talks after completion of the writing task requiring citation along with their works. The purpose is to find clues for effective teaching of citation, one of the necessary skills for academic writing. In a writing class for advanced level learners, I introduced a practice determining whether to use direct citation or indirect citation for several times during the course. The said task was given at the closing hours. First I would examine effectiveness of the practice and then present the clues for further teaching.
