This study analyze data from three national contexts in which teachers worked with the same teaching materials and inquiry classroom activities, investigating teachers' use of strategies to promote interaction and scaffolding when participating in a professional development program. The data material is collected from three case studies from the…

Quantum physics is challenging for young students, but also a source of fascination. "Observation" is a key concept in order to understand how principles and experimental results in quantum physics differ from what we are used to in classical physics and everyday experiences. In this study we investigate how pre-university physics…

The rise in carbon dioxide (CO[subscript 2]) concentration in the Earth's atmosphere, and the associated strengthening of the greenhouse effect, requires the development of low carbon technologies. New carbon capture processes are being developed to remove CO[subscript 2] that would otherwise be emitted from industrial processes and fossil fuel…

The relationships between teacher and students are interdependent and rely on their mutual interaction. In the classroom, teaching involves daily face-to-face encounters between students and teachers and therefore could be considered a moral as well as an academic issue. A central question is how the teacher can establish and support a learning…

While it is generally assumed that the aim of teacher evaluation is to "formatively" support teachers' professional development, research finds that teacher evaluation practices are predominantly "summative". This paper describes a Norwegian governmental policy experiment aiming to overcome this fallacy through a bargaining…

In this article, we examine the relationship between how students are positioned in social encounters and how this influences learning in a technology-supported science project. We pursue this topic by focusing on the participation trajectory of one particular learner. The analysis shows that the student cannot be interpreted as one type of…

Understanding the effects of class size reduction (CSR) has been an enduring issue in education. For the past 3 decades, Project STAR has stimulated research and policy discussions regarding the effects of CSR on a variety of outcomes. Schanzenbach (2007) reviewed STAR studies and concluded that small classes improved student academic outcomes.…
