Exploring the Use of Electroencephalography to Gather Objective Evidence of Cognitive Processing During Problem Solving

Currently, there is significant interest being directed towards the development of STEM education to meet economic and societal demands. While economic concerns can be a powerful driving force in advancing the STEM agenda, care must be taken that such economic imperative does not promote research approaches that overemphasize pragmatic application at the expense of augmenting the fundamental knowledge base of the discipline. This can be seen in the predominance of studies investigating problem solving approaches and procedures, while neglecting representational and conceptual processes, within the literature. Complementing concerns about STEM graduates’ problem solving capabilities, raised within the pertinent literature, this paper discusses a novel methodological approach aimed at investigating the cognitive elements of problem conceptualization. The intention is to demonstrate a novel method of data collection that overcomes some of the limitations cited in classic problem solving research while balancing a search for fundamental understanding with the possibility of application. The methodology described in this study employs an electroencephalographic (EEG) headset, as part of a mixed methods approach, to gather objective evidence of students’ cognitive processing during problem solving epochs. The method described provides rich evidence of students’ cognitive representations of problems during episodes of applied reasoning. The reliability and validity of the EEG method is supported by the stability of the findings across the triangulated data sources. The paper presents a novel method in the context of research within STEM education and demonstrates an effective procedure for gathering rich evidence of cognitive processing during the early stages of problem conceptualization.     

Integrated policies for the preparation of educational personnel

Drawing on the literature and developments in Lifelong Education in the 1960s and 1970s, this paper seeks to offera contribution to the updating of the concept to address the pressing new needs of the 1980s for integrated policies for the preparation of educational personnel. Such policies are seen as necessitating the ability to forge new curricula across sectoral boundaries, linking education and economic activity, school and community, and achieving delivery in different modes and locations. The article offers a conceptualization of policy options for such preparation, comprising four major dimensions, each comprehending tendencies to conservation and change. The author proceeds to illustrate the conceptualization by reference to programmes provided, often on an inter-agency basis, in the United Kingdom by the Manpower Services Commission. The paper concludes by highlighting the continuing disjuncture between education and training and between education and national needs in many developing countries, partly as a legacy of colonial concepts of schooling, and points to the requirement for comprehensive and coherent policies which can link education and the economy and schooling and training, harnessing them to the response to pressing national needs.

Zusammenfassung Gestützt auf die Literatur und Entwicklungen im Bereich des Lebenslangen Lernen in den 60er und 70er Jahren versucht der Verfasser dieses Artikels eine Aktualisierung des Konzepts, um auf die dringenden neuen Bedürfnisse der 80er Jahre für integrierte Richtlinien zur Vorbereitung des Erziehungspersonals einzugehen. Schwerpunkte dieser Richtlinien sind: neue Curricula über Sektorengrenzen hinweg zu entwickeln, Bildung und wirtschaftliche Aktivität sowie Schule und Gemeinschaft miteinander zu verbinden und auf verschiedene Art und Weise und an verschiedenen Standorten zu vermitteln. Im nachfolgenden Artikel wird eine Konzeptualisierung der Optionen bei Richtlinien für eine derartige Vorbereitung angeboten, die aus vier Hauptdimensionen besteht. Jede diese Hauptdimensionen enthält Tendenzen zu Erhaltung und Veränderung einschließen. Der Verfasser veranschaulicht die Konzeptualisierung mit einem Verweis auf die im Vereinigten Königreich von Manpower Services Commission angebotenen Programme, die häufig auf einer Vermittlungsbasis zwischen den verschiedenen Regierungsstellen beruhen. Abschließend betont der Verfasser die fortdauernde Trennung zwischen Bildung und Ausbildung sowie zwischen Bildung und nationalen Bedürfnissen in vielen Entwicklungsländern, die teilweise als ein Erbe kolonialer Entwicklungskonzepte weiterbestehen. Es besteht ein Bedarf nach umfassenden und kohärenten Methoden, die Bildung und Wirtschaft sowie Erziehung und Ausbildung verknüpfen und sie an eine Antwort auf dringende nationale Bedürfnisse koppeln.

Résumé S'inspirant de la littérature et des développements de l'Education Permanente enregistrés au cours des années soixante et soixante-dix, cet article s'efforce d'apporter une contribution à la mise à jour de ce concept afin de présenter les nouveaux besoins pressants apparus dans les années quatre-vingts aux politiques intégrées pour la formation du personnel enseignant. On considère que de telles politiques nécessitent la capacité de forger de nouveaux curricula à travers les limites sectorielles, établissent des liens entre l'éducation et l'activité économique, l'école et la communauté, et opèrent de diverses manières et en différents endroits. L'article présent offre une conceptualisation des options politiques pour une telle préparation, qui englobe quatre grandes dimensions, chacune d'elles renfermant des propensions à l'invariabilité et à l'évolution. L'auteur illustre ensuite cette conceptualisation en se référant aux programmes offerts, sur une base interopérationnelle souvent, au Royaume-Uni par la Commission des Services de la Main-d'Oeuvre. Il conclut en soulignant l'incohérence constante entre l'éducation et la formation, l'éducation et les besoins nationaux que de nombreux pays en développement ont hérités en partie de concepts coloniaux d'éducation et il met en relief la nécessité de politiques générales et cohérentes capables de nouer des liens entre l'éducation et l'économie, l'instruction et la formation, les exhortant à répondre aux besoins nationaux urgents.

The multimedia case as a tool for professional development: an analysis of online and face-to-face interaction among mathematics pre-service teachers, in-service teachers, mathematicians, and mathematics teacher educators

In this study, we consider the potential of multimedia cases as tools for teacher professional development. Specifically, we examined online and face-to-face discussions that occurred within groups composed of pre-service mathematics teachers, in-service mathematics teachers, mathematicians, and mathematics teacher educators. Discussions within these heterogeneous groups tended to focus on issues of classroom implementation of the tasks shown in the multimedia case. Secondary foci of discussion included task characteristics and appropriateness of tasks for engaging students in thinking about mathematical concepts and processes. Analysis of contributions to discussions across group member type revealed differences that suggest that the variety of backgrounds and experiences of group members can blend in ways that support rich and critical discussions of mathematics, teaching, and learning.     

A retrospective view of a study of middle school science curriculum materials: Implementation,scale‐up,and sustainability in a changing policy environment

This article provides an extended, comprehensive example of how teachers, schools, districts, and external factors (e.g., parental pressure and policy mandates) shape curriculum research in the U.S. It retrospectively examines how three different middle school curriculum units were implemented and scaled‐up in a large, diverse school system. The curriculum materials were cognitively based, hands‐on, guided inquiry units; each focused on a different “big idea” in science. The units met some criteria for instructional strategies rated by the Project 2061 Curriculum Analysis. Using evidence‐based decisions, two of the units were found to be effective and equitable, and went to scale, but one was not effective. However, the course of scale‐up was also affected by a changing policy climate, and proceeded in unpredictable ways, with small scale effects not found at large scale, and experienced teachers less effective than inexperienced teachers. Four years after funding ended, none of the units were sustained within the school district. The interactions between the demands of the units and of the school district's policy environment suggests reasons why this occurred, despite evidence that two of the units were successful with diverse learners. © 2012 Wiley Periodicals, Inc.

Children's conceptions of the earth,sun and moon

Understanding of the Earth/Sun/Moon system represents a major cultural nexus in the history of ideas as well as being an important conceptual area in junior science teaching. The situation is one in which the objects in question can be observed but do not lend themselves to hands‐on experience in the case of the Sun and Moon or to obvious meaningful experience of the system in the case of the Earth.

Children from 9 to 12 years of age were questioned using a clinical interview technique and stimulus materials, about the shape, size and motion of the Earth, Sun and Moon. A number of alternative views appear to be held. The use of a similar procedure with a group of children would seem to offer a powerful teaching methodology in which both teacher and students gain from the dialectic learning situation that is developed by this technique ‐ apart from providing insights concerning children's understanding.     

Creating a dialogue between sociological and egalitarian theory in education

No one discipline has a monopoly on the truth, especially in the analysis of a complex subject such as equality. If we are to deepen our understanding of inequality in education, we must open a dialogue with other disciplines, most especially with egalitarian theory. Bearing in mind the limitations of writing in a majority language tradition, the article explores the potential for creating a dialogue about equality between sociologists and critical and feminist egalitarian theorists. What sociologists can gain from egalitarian theory is a deepening of their understanding of the interface between the ethical and the empirical, of the interrelationship between fact and value in social life. In addition, egalitarian theory has the capacity to broaden our understanding of inequality in education beyond the distributive view of social justice that has dominated thinking in education to date. Drawing on the work of egalitarian theorists the article outlines four particular interpretations of equality that have relevance for researchers in education.     

Breaking silence: educating citizens for love,care and solidarity

An indifference to the affective domain and an allegiance to the education of the rational autonomous subject and public citizen are at the heart of formal education. The impact of Cartesian rationalism is intensifying with the glorification of performativity measured by league tables and rankings. The citizen carer and the care recipient citizen are only recognised in the educational arena when professionals are being trained to manage those in need of care. Education for informal care labour, solidarity work and love labour is generally not part of the formal educational trajectory. Because the scholarly understanding of work has been equated with economic self preservation and self‐actualisation through interaction with nature, education is seen as preparation for this type of work. Education is indifferent to other‐centred work arising from our interdependencies and dependencies as affective, relational beings. In particular it has ignored the centrality of nurturing for the preservation and self‐actualisation of the human species. In this article the authors argue that sociologists need to engage with the extensive feminist scholarship on care if they are to challenge the deeply care‐less view of the citizen that is implicitly accepted in new and older forms of liberal thinking. The rational economic actor model of the citizen is contrasted with the care‐full view of the citizen and the implications of both for education are explored.
