Teaching about the nervous system has become a challenging task in secondary biology and science education because of the fast development in the field of neuroscience. A major challenge is to determine what content to teach. Curricula goals are often too general to guide instruction, and information about the nervous system has become overwhelming and diverse with ubiquitous relevance in society. In addition, several misconceptions and myths are circulating in educational communities causing world-wide confusion as to what content is correct. To help teachers, textbook authors, and curricula developers in this challenging landscape of knowledge, the aim of the present study is to identify the expert view on what knowledge is important for understanding the nervous system in the context of secondary biology and science education. To accomplish this, we have conducted a thematic content analysis of textbooks followed by a Delphi study of 15 experts in diverse but relevant fields. The results demonstrate six curriculum themes including gross anatomy and function, cell types and functional units, the nerve signal, connections between neurons, when nerve signals travel through networks of neurons, and plasticity in the nervous system, as well as 26 content principles organized in a coherent curriculum progression from general content to more specific content. Whereas some of the principles clarify and elaborate on traditional school biology knowledge, others add new knowledge to the curriculum. Importantly, the new framework for teaching about the nervous system presented here, meets the needs of society, as expressed by recent international policy frameworks of OECD and WHO, and it addresses common misconceptions about the brain. The study suggests an update of the biology and science curriculum., Competing Interests: The authors have declared that no competing interests exist.

‘Open schooling’ has become in recent years a burgeoning theme in the discourse on how to rethink education for the 21st century. This paper addresses a gap between calls for implementing an open schooling approach in policy papers and international reports and the scarcity of rigorous academic discourse on what open schooling theoretically means and practically entails in terms of school organization and curriculum. To this end, the paper presents an ecological model of school openness that is composed of eight interrelated dimensions: shared governance, ‘open’ curriculum, inner-school communities, learning communities, student participation, social engagement, parental involvement, and community collaborations. These dimensions are organized into three categories, accounting for organizational, pedagogical and communal aspects of school openness. The multidimensional nature of the model presented here provides a more intricate and nuanced account of open schooling that acknowledges the complexities and challenges that the movement towards greater openness yields for school communities. From an educational research perspective, this model functions to inform the understanding and examination of the multidimensionality of opening schools to their community. From an educational practice perspective, it can instigate in-depth and meaningful dialogue within school teams on what open schooling is and its ensuing merits. [ABSTRACT FROM AUTHOR]
