Secondary science teachers participated in a socio-scientific issues (SSI) professional development (PD) during which they co-designed SSI curriculum units. In this qualitative multiple case study, we followed a sub-set of eight teachers who enacted their SSI units in their classrooms and agreed to participate in the study. Clarke and…

Currently there is little guidance given to teachers in selecting focal issues for socio-scientific issues (SSI)-based teaching and learning. As a majority of teachers regularly collaborate with other teachers, understanding what factors influence collaborative SSI-based curriculum design is critical. We invited 18 secondary science teachers to…

While much is known about the characteristics that researchers deem valuable for professional development (PD), teachers' perceptions of their PD needs are less understood. In this study, we sought to explore teachers' perceptions of their PD needs, including PD format, time frame, and topics covered, and how those perceptions varied by teachers'…

Background: For the past decade, science educators have been exploring the use of Socio-scientific Issues (SSI) as contexts for science teaching and learning, and research indicates that doing so can support significant learning gains. However, research related to how teachers take up the practice of SSI-based instruction is far more limited, due…

Previous literature has documented how teachers perceive both advantages and disadvantages associated with standards-based reform. These teacher perceptions may be connected to classroom practices in terms of the extent to which standards are utilized by individual teachers. The purpose of this study was to identify how secondary science teachers…
