The present case study examines a teacher's scaffolding strategies supporting his students during a twelve-week open inquiry project at an upper secondary school. We use interaction analysis to identify how he provides structure and space in the different phases of open inquiry as well as how it constitutes the students' inquiry process. The study reveals that the teacher scaffolded this open inquiry in two opposing ways; he created space for the students to make their own experiences and ideas, which eventually set up the need for more directed scaffolding to discuss the challenges students experienced, and directing students' ideas in certain directions in phases with structure. We suggest that the interplay between structure and space creates what can be seen as a driving force providing both exploration and direction for open inquiry. Moreover, we propose that the dual concept of 'structure and space' can work as a thinking tool to promote teachers' competence on how to scaffold more authentic versions of scientific inquiry in schools.
IntroductionScience education reforms all over the world advocate a view of learning science that emphasises inquiry (e.g. European Commission, 2007; Norwegian Ministry of Education, 2006; NRC, 2000). In the classroom, the term 'inquiry' can be understood with two different emphases: the experiments and activities that facilitate the students' learning of established sciences, and the scientific thinking and practices in which students engage when they model professional scientists (Asay & Orgill, 2010) -which is in focus in the classroom studied here. Specifically, open inquiry has been proposed as a means to enhance more authentic scientific inquiry (Duschl & Grandy, 2008;Roth, 2012) and promote active and autonomous learning (Hodson, 2009). However, change in school science depends upon how teachers conceptualise inquiry and how it is translated into classroom practice. Thus, we need to understand how the actions of the teacher influence the nature of the inquiry-based instruction and the students' learning experiences (Blanchard et al., 2010;Hmelo-Silver, Duncan and Chinn, 2007).Birgitte Bjønness is associate professor in science education at the Norwegian University of Life Sciences. Her research interests involve inquiry-based learning, biology education and education for sustainable development.Stein Dankert Kolstø is professor in science education at the University of Bergen. His research interests focuses on use of dialogue and inquiry in science learning. In specific, he is interested in combining dialogic inquiry with the use of authentic texts related to socioscientific issues.
