Using Sociocultural Theory to Understand the Relationship between Teacher Change and a Science-based Professional Education Program

This paper focuses on a model of teacher change based on a study of a science discipline-based professional education program and on an understanding of teacher change in terms of an agency| structure dialectic. Professional education programs should expand teachers' capacity to act in a range of fields. Conducted over one year, this study used socio-cultural theory to examine the role of cultural schema and resources in the enactment of new pedagogical structures by two teachers who demonstrated widely variable responses to their experience of a professional chemistry education program. Hermeneutic and phenomenological methods of study supported the examination of teacher actions and narratives as sources of data. The analyses of these data sources resulted in greater understanding of the relationship between schema, resources and structure and the relationship between structure and teacher agency. Structures are dynamic and if a teacher uses a resource such as an inquiry-based instruction protocol without the attendant cultural schema such as the value of questioning then the structure that is implemented will be different from that the teacher experienced in the professional education program. This understanding supported an explanation of teacher change in terms of teacher agency that constituted our learning from the study and resulted in changes to aspects of the professional education program.

Using Vygotsky’s zone of proximal development to propose and test an explanatory model for conceptualising coteaching in pre-service science teacher education

Coteaching offers a model for the school-placement element of pre-service science teacher education, based on its demonstrated positive impacts on lessening classroom anxiety, supporting inquiry-based science teaching, improving students’ attitudes, and addressing diversity effectively in science classrooms. Coteaching between pre-service and in-service teachers is used to lessen the gap between theory and practice, to develop reflective practice and to develop pedagogical content knowledge. Explanatory frameworks have been proposed for coteaching, and we suggest that Vygotsky’s zone of proximal development helps to propose a more nuanced developmental and learning explanatory framework which provides pedagogical structures for implementation and highlights the importance of the social environment for learning. In providing structure and tools for effective implementation of coteaching, our model addresses three core elements of coteaching: coplanning, copractice, and coevaluation. The model was piloted in relation to pre-service teachers’ development in reflective practice and reducing the gap between theory and classroom practice.     

Using the Content of Online Privacy Notices to Inform Public Policy: A Longitudinal Analysis of the 1998-2001 U.S. Web Surveys

In the United States, Congress has had a long-standing interest in consumer privacy and the extent to which company practices are based on fair information practices. Previously, public policy was largely informed by anecdotal evidence about the effectiveness of industry self-regulatory programs. However, the Internet has made it possible to unobtrusively sample web sites and their privacy disclosures in a way that is not feasible in the offline world. Beginning in 1998, the Federal Trade Commission relied upon a series of three surveys of web sites to assess whether organizations post online privacy disclosures and whether these disclosures represent the U.S. definition of fair information practices. While each year's survey has provided an important snapshot of U.S. web-site practices, there has been no longitudinal analysis of the multiyear trends. This study compares a subset of equivalent individual-level web-site data for the 1998, 1999, 2000, and 2001 web surveys. Implications for using this type of research to inform public policy are discussed.     

Pharmaceutical prospects: biopharming and the geography of technological expectations

The paper explores the role of imagined geographies in the shaping of new technologies. I argue that the role of place in future-oriented visions of technoscience is a neglected topic in studies of the social shaping of technology. The paper proposes an approach that combines the sociology of expectations with the geography of science. It focuses on the interplay between envisaged and current geographies to highlight the recursive dynamics of place and imagination. To illustrate this approach, the paper discusses the example of biopharming, the production of biopharmaceuticals using genetically modified crops. I argue that expectations for biopharming bear the imprint of place, or rather of the places in which they are imagined, as well as those they imagine, and ultimately those they produce. I use this example to suggest how social studies of science and technology can usefully investigate the spaces, places and scales of technological development.     

The BBC's Educational Posture

The BBC has a lasting and massive commitment to education. At a time of difficulty for education and of momentous changes to broadcasting technology and opportunities, it is time to confirm and strengthen that commitment. Among concerns requiring the special attention of educational broadcasting are unemployment and retraining, the ageing population and health care, and ethnic minorities. The opportunities for educational broadcasting in the future can only be enhanced, and certainly not diminished.     

The Efficacy of Preschool Developmental Indicators as a Screen for Early Primary School-Based Literacy Interventions

Literacy success lays the foundation for children's later educational, health, and well-being outcomes. Thus, early identification of literacy need is vital. Using data from New Zealand's national preschool health screening program for fiscal years 2010/2011–2014/2015, demographic and health variables from 255,090 children aged 4 years were related to whether they received a literacy intervention in early primary school. Overall, 20,652 (8.1%) children received an intervention. Time-to-event analysis revealed that all considered variables were significantly related to literacy intervention (all p < .01), but the full model lacked reasonable predictive power for population screening purposes (Harrell's c-statistic = .624; 95% CI [.618, .629]). Including more direct literacy measures in the national screening program is likely needed for improvement.
