Professional Learning Portfolios for Argumentation in School Science

This paper reports on the use of portfolios in a continuing professional development programme to advance teachers’ skills in their pedagogy of argumentation. The programme adopted a cyclical process of expert input- teacher practice- sharing practice, in order for professional learning to include reflective analysis of growing accomplishment. Accomplishment was initially defined according to previous research and development on the teaching of argumentation, but was redefined during the programme as teachers shared practice and discussed their achievements. Portfolios were used to help teachers apply their learning, collate evidence of their accomplishment and share reflective analysis of practice with other colleagues on the programme. The paper includes extracts of two teachers’ portfolios; these provide evidence of each teacher’s developing accomplishment in the teaching of argumentation. Portfolios are idiosyncratic and are constructed according to an individual teacher’s motivations, interpretations and situations. Teachers need structure and guidance in creating purposeful portfolios that enhance reflective practice

Realising Potential: Disability Confidence Builds Better Business

[Excerpt] ‘Realising potential’ sets out the latest thinking on how disabled people contribute to business success and how business, in the UK and globally, benefits from disability confidence. It provides the information senior business decision makers need to manage and profit from the disability dimension to key business trends: including an aging population, increasingly individualised customer relations, changing working patterns and enabling technology. Business must address the disability component of these trends and develop disability confidence if it is to compete in an increasingly complex environment and create value from difference. ‘Realising potential’ highlights the strategic, commercial, legal, societal, ethical, and professional benefits of getting it right on disability – the six building blocks of any business case for disability confidence

Curvature and Concentration of Hamiltonian Monte Carlo in High Dimensions

In this article, we analyze Hamiltonian Monte Carlo (HMC) by placing it in the setting of Riemannian geometry using the Jacobi metric, so that each step corresponds to a geodesic on a suitable Riemannian manifold. We then combine the notion of curvature of a Markov chain due to Joulin and Ollivier with the classical sectional curvature from Riemannian geometry to derive error bounds for HMC in important cases, where we have positive curvature. These cases include several classical distributions such as multivariate Gaussians, and also distributions arising in the study of Bayesian image registration. The theoretical development suggests the sectional curvature as a new diagnostic tool for convergence for certain Markov chains.Comment: Comments welcom

Attitudes towards science: a review of the literature and its implications

This article offers a review of the major literature about attitudes to science and its implications over the past 20 years. It argues that the continuing decline in numbers choosing to study science at the point of choice requires a research focus on students? attitudes to science if the nature of the problem is to be understood and remediated. Starting from a consideration of what is meant by attitudes to science, it considers the problems inherent to their measurement and what is known about students' attitudes towards science and the many factors of influence such as gender, teachers, curricula, cultural and other variables. The literature itself points to the crucial importance of gender and the quality of teaching. Given the importance of the latter we argue that there is a greater need for research to identify those aspects of science teaching that make school science engaging for pupils. In particular, a growing body of research on motivation offers important pointers to the kind of classroom environment and activities that might raise pupils' interest in studying school science and a focus for future research

Probabilistic Political Viability: A Methodology for Predictive Political Economy

Currently available political economic tools are not very useful for predicting the outcomes of real-world policy problems. Researchers have limited information on which to assign parameters to the mappings from policies to outcomes to utilities or to represent the political process adequately. We present a method for evaluating the viability of political alternatives in complex settings and apply it to an ongoing California water policy debate. Certain options would be "robustly politically viable" if stakeholder groups trusted that they would be implemented as negotiated. Once we incorporate institutional mistrust into the model, none of the alternatives are robustly politically viable.
