This work aimed to investigate how a formative process can contribute to provide new meaning for chemistry teachers' conceptions about Science, Technology, Society and relationships among them, considering these conceptions are important to implement STS approaches for science teaching. Three teachers of chemistry from different public and private schools were involved in this research. Individual interviews were performed with teachers e their conceptions also were analysed from discussions in a workshop. Data analysis revealed some teachers' conceptions seem not be compatible with those required for STS approach, and showed that is crucial to involve teachers in discussions about their conceptions. For this, workshops were performed and discussions pointed out a tendency for construction of new ideas by teachers, highlighting the importance of previous formative process for STS approach in classroom.
