Argumentation in school science : Breaking the tradition of authoritative exposition through a pedagogy that promotes discussion and reasoning

The value of argumentation in science education has become internationally recognised and has been the subject of many research studies in recent years. Successful introduction of argumentation activities in learning contexts involves extending teaching goals beyond the understanding of facts and concepts, to include an emphasis on cognitive and metacognitive processes, epistemic criteria and reasoning. The authors focus on the difficulties inherent in shifting a tradition of teaching from one dominated by authoritative exposition to one that is more dialogic, involving small-group discussion based on tasks that stimulate argumentation. The paper builds on previous research on enhancing the quality of argument in school science, to focus on how argumentation activities have been designed, with appropriate strategies, resources and modelling, for pedagogical purposes. The paper analyses design frameworks, their contexts and lesson plans, to evaluate their potential for enhancing reasoning through foregrounding the processes of argumentation. Examples of classroom dialogue where teachers adopt the frameworks/plans are analysed to show how argumentation processes are scaffolded. The analysis shows that several layers of interpretation are needed and these layers need to be aligned for successful implementation. The analysis serves to highlight the potential and limitations of the design frameworks

What Makes Professional Development Coherent? Uncovering Teacher Perspectives on a Science Literacy Project

In this study, the authors sought to uncover the characteristics of professional development (PD) that were identified by teacher-participants as being important to their implementation of project ideas. Using phenomenological interviewing, the authors talked with nine teacher-participants about changes to their teaching practices after they participated in a university-based PD program focused on science literacy. Findings indicate that teachers benefited from immersion in authentic practices with an expert facilitator, a clear definition of science literacy that challenged teachers’ previous understandings, and ongoing contact with a community of like-minded educators for collaboration and recognition. Findings confirm previous research and expand our understanding of the concept of “coherence” in professional development
