Enacting President Trump’s leadership contract with educators: toward a communal leadership perspective

This article proposes the communal leadership framework as a leverage for reciprocal educational policy in uncertain and turbulent times. It is argued that leadership at the policy level should abandon the seductive dance with the ‘self’ where knowledge resides at a specific location in the system (policy-makers’ perceptions and agendas) for a more holistic, integrated, and collaborative framework – that of communal leadership – in order to develop effective policies suitable for today's fast-changing educational world. This article presents the epistemological premises postulated as upholding the communal nature of leadership, while raising conceptual as well as practical questions in this context.     

Diversity,Community, and Pluralism in Jewish Community Day High Schools

Students in “community” (nondenominational) Jewish high schools represent a diversity of denominational affiliations, including those who affiliate with more than one denomination and those that affiliate with none. These schools strive to create communities in which students with varying Jewish beliefs and practices are, at the very least, respected and comfortable. At the same time, schools work to avoid internal Jewish communal fragmentation. In this article, the approach to diversity in three such high schools is compared. Each school, in addition to presenting an approach distinct from the others, has created opportunities for communal Jewish engagement through the enactment of practices that are rooted in Judaism and in the ethos of the school, and allow individualization within universal participation. Further, the range of approaches to Jewish diversity exhibited raises questions about pluralism as it relates to the Jewish educational goals of these schools.

Social disorganization and the profile of child welfare: Explaining child welfare activity by the community-level factors

This article addresses the question of the structure of local child welfare activities in light of community-level factors. It poses the following research questions: how are different community-level factors related to child welfare client structures in communities and what is the extent to which these factors explain structural differences? The applied theoretical framework is based on social disorganization and strain theories as well as human developmental approach. The data has been collected from two Finnish national databases and it consists of variables containing 257 Finnish municipalities. The method of analysis is multinomial logistic regression. The results suggest that the local child welfare structures are tied to social disorganization, policing and culture as well as to the intensity of control in the communities. In general, the more fragile the communal structures, the more last-resort child welfare there is in the community. Combining fragile communal structures with weak dependency ratio and high proportion of social workers, the more intense the level of child welfare statistics indicated. The results indicate that the theoretical framework for the application of child welfare activity analysis is justified, but they also suggest that it requires further development through both context-bound reflection and application.     

On Their Own but Not Alone: The Difficulty in Competence-Oriented Approaches to Teaching Reading and Writing of Thinking of ‘Performance’ in Communal Terms*

Among educators in the field of language and literature, in the German-speaking world and beyond, the concept of ‘competence’ has been gaining ground for three decades. This article questions the validity of prevalent competence definitions, which by focusing on the proficiency of an individual student ignore the fact that in understanding literature, as well as in composition, communal achievement is essential. By drawing on evolutionary anthropology and by collecting evidence from studies in literary and composition learning, the author draws on his own teaching experience to show that students’ competence develops by interaction. Educational research, however, widely fails to take this into account.

Faith Tribes as Powerful Communities of Adolescents in Highly Differentiated Societies

This article describes how communal aspects of faith find their way back into the lives of adolescents. The communal aspects of faith within individualized societies need more attention. It seems that with the current emphasis on individual faith, the intrinsic power of communal aspects of faith has been lost. This study shows that informal communities of adolescents—faith tribes—can restore the individual–communal balance in faith development. Youth ministry should encourage adolescents and tribal leaders to be aware of the faith possibilities of tribes.

Exploring the contexts of urban science classrooms. Part 2: The emergence of rituals in the learning of science

In Part 1 of this paper, I described the corporate and communal nature of research, teaching, and learning in urban science classrooms as both a theoretical approach to understanding, and way of viewing practices within these fields. By providing a new approach to theorizing the cultural misalignments that are prevalent in urban schools, I look to provide an informative tool for investigating under-discussed dynamics that impact science teaching and learning. In this body of work, I further expose the nature of the corporate|communal by describing practices that define communal practice. I do so conversant of the fact that synthesizing my previous work on corporate and communal practices necessarily pushes science education researchers and teachers to look for somewhat tactile explications of communal practices. That is to say, if communal practices do exist within the corporate structures of science classrooms, how do they present themselves and how can they be targeted? This paper begins a journey into such a study and focuses on student transactions, fundamental interactions and rituals as a key to redefining and attaining success in urban science classrooms.
