One problem for junior high school students is the difficulty in identifying important content among the many matters learned during classes. Metacognitive or metalinguistic ability offers a means of dealing with this problem. Metalinguistic ability is the ability to be aware of one's own knowledge and skills, and is thought to be very important in learning foreign languages. In this study, we attempted to activate students' metalinguistic ability by getting them to formulate questions about a text they had just read. We concluded that some students were able to develop their reading comprehension ability in this way, but we were unable to determine a clear relationship between reading comprehension and formulating questions. However, many students enjoyed making questions and were able to develop their grammatical awareness and inferential ability in this way.
