Are there some questions that can’t be answered? The limits of research in teacher education

Series
Department of Education Public Seminars
Embed
A public seminar from the Department of Education, delivered by Dr Katharine Burn and Trevor Mutton.
This year will see the publication of no fewer than four high­profile reports into different aspects of teacher education (BERA­RSA, UUK, IFS/Nuffield, DFE Carter Review). Clearly a lot of questions are being asked and a wide range of evidence is being marshalled, although each of them is limited in different ways by their particular terms of reference, and by the perceptions of institutional bias that might colour the ways in which they are interpreted. However, even if all such potential bias could be eliminated, there remain doubts about the capacity of even the highest­ quality research to answer the fundamental question driving any investigation into the effectiveness of teacher education – its impact on student outcomes.
Drawing on their paper commissioned for the BERA­RSA Inquiry into the role of research in teacher education, and on their previous longitudinal research into the nature of beginning teachers’ learning, Katharine Burn and Trevor Mutton will explore some of the reasons for this apparent impasse and consider the range of ways in which teacher education researchers and practitioners might respond.

The rise and rise of testing and use of assessment data in Australia

Series
Department of Education Public Seminars
Embed
A public seminar from the Department of Education, delivered by Professor Val Klenowski, Queensland University of Technology.
In 2008 testing became high stakes in Australia and since that time we have witnessed the rise of a major industry with the emergence of readily available practice tests for purchase, increased provision of online resources and burgeoning tutoring services focused on National Assessment Program – Literacy And Numeracy (NAPLAN) style tests. This presentation will critically examine the emergent issues for students, schools, parents and systems and will argue for a more balanced approach of formative and summative assessment with greater professional and system level understanding of the validity of the primary and secondary uses of assessment data. Empirical evidence is drawn from two recent studies of how assessment data is used by schools and systems for the purposes of accountability and improvement. One study is an Australian Research Council Linkage project entitled “Ethical Leadership: A collaborative investigation of equity­driven evidence­based school reform” and the other draws on the largest collection and analysis of research data on multiple facets of Aboriginal and Torres Strait Islander education in state schools. Key emergent issues relate to the current evaluation system and whether the major assessment instruments actually assess what constituent communities, governments and the public deem to be of value. With the requirement for greater effectiveness, equity and quality in education to meet economic, social and political demands major tensions and pressures have arisen.

Realist Review: Mixing Method

Series
Evidence-Based Health Care
Embed
This talk will introduce the realist review methodology as a strategy for combining qualitative and quantitative data to answer the question “what works, for whom, and in what circumstances”

This methodology is proving popular in addressing questions around complex and social interventions. The talk will provide a brief overview of approaches to synthesizing qualitative and quantitative research for mixed methods reviews, discuss approaches to dealing with different study types in realist reviews, and question the adequacy of published studies when developing theory for complex interventions.

A Physicist’s View of the Emergence of Terrestrial Vertebrates

Series
Oxford Physics Public Lectures
Embed
Physics Colloquium 7th November 2014. Delivered by Professor Steve Balbus, Savilian Professor of Astronomy, Head of Astrophysics, University of Oxford.
The very similar angular sizes of the Sun and Moon subtended at the Earth is generally portrayed as coincidental. In fact, close angular size agreement is a simple mathematical consequence of even roughly
comparable lunar and solar tidal amplitudes. I will argue that the latter was a biological imperative. Comparable tidal amplitudes, sharing close but distinct frequencies, leads to beats and strongly modulated forcing. This tidal pattern must be understood in thecontext of paleogeographic reconstructions of the Late Devonian period. As seen below, two great land masses were separated by a broad western opening to the Rheic Ocean, tapering to a very narrow, shallow-sea strait. A classic WKB wave analysis suggests that the combination of this geography and modulated tidal forces would have been conducive to forming a rich inland network of shallow and transient tidal pools at an epoch when tetrapods were evolving. I will discuss the fossil evidence showing that important transitional species lived in habitats strongly influenced by intermittent tides. When the waters became anoxic, perhaps from sustained inwash of organic debris, a mass extinction ensued. The tetrapods endured, however, and we are their legacy.

Systematic Reviews, the need for change

Series
Evidence-Based Health Care
Embed
The need to generate systematic reviews is relatively uncontroversial and until recently so were the methods of production.

The presentation will highlight a number of problems associated with the current system and propose a radical departure to ensure we meet Archie Cochrane's desire to see all RCTs included in critical summaries.

Science and the Art of Inventiveness

Series
Oxford Physics Public Lectures
Embed
Physics Colloquium 24th October 2014. Delivered by Professor Andrei Seryi, Director of the John Adams Institute.
Science has yielded a rich history of inventions, ones often inspired by Nature itself. Despite all this progress, we have always strived to find more efficient approaches to inventing. In fact, during the second half of the 20th century, the industrial world developed specific methodologies with which to promote inventiveness. Though powerful, these methods were rarely heard of outside of their field, let alone in the scientific community. The most advanced methodology, the so-called “theory of inventive problem solving”, has become, according to Forbes, the bedrock of innovations in such companies as Samsung. While the industrial inventiveness methods were originally created for engineering, their methodologies are universal and can also be applied to science. In this lecture we shall show how the theory of inventive problem solving can be used in various areas of science – from philology to accelerator physics – in order to create a powerful and eye-opening amalgam of science and inventiveness.
Prof Andrei Seryi’s forthcoming book, Unifying Physics of Accelerators, Lasers and Plasma, is due to be published by CRC Press / Taylor & Francis in 2015 (http://www.crcpress.com/product/isbn/9781482240580). This book will include detailed descriptions of the topic discussed in this colloquium – the theory of inventive problem solving in application to science and the method of Accelerating Science TRIZ (AS-TRIZ), and will use this method throughout the book in applications to accelerators, lasers and plasma. The book will be suitable for students of various levels between senior undergraduate and graduate students in physics who are interested in enhancing their ability to work successfully on the development of the next generation of facilities, devices, scientific instruments, arising from synergy of accelerators, laser, and plasma. This book could also attract anyone interested in scientific innovations.

A Neandertal Perspective on Human Origins

Series
Keble College
Embed
Professor Svante Paabo, Director of the Department of Genetics at Max Planck Institute for Evolutionary Anthropology, Germany delivers the ASC Annual Lecture.
In 2010, the first draft version of the Neandertal genome revealed that Neandertal have contributed genetic material to present-day humans living outside Africa. Recently, we have completed a genome sequence of high quality of a Neandertal individual and also of a Denisovan individual, representing a hitherto unknown Asian group related to Neandertals. These genomes reveal that up to about 2.0% of the genomes of people in Eurasia derive from Neandertals while about 4.8% of the genomes of people living in Oceania derive from Denisovans. I will discuss what is currently known about the functional consequences of the Neandertal inheritance in present-day humans. I will also describe how the Neandertal genome allows novel genomic features that appeared in present-day humans since their divergence from the Neandertal lineage to be identified and discuss how they may be functionally analyzed in the future.
