The purposes of this study were to develop a consumer education lesson that is practiced in preservice teacher training class, as well as to confirm that, by implementing this lesson, the student teachers were able to identify important elements so to avoid consumer problems. The authors put the lesson into practice with five classes on consumer education using QFT (Question Formulation Technique) for student teachers at the university level. As a result, the student teachers in all five classes were able to actively create questions about the lesson content related to consumer education and information communication technology education, from various viewpoints, without being explained, questioned, or instructed by the facilitating professors. Furthermore, the student teachers were able to learn a new teaching method by experiencing the QFT classes.
