Policy Shifts in Language-Minority Education: A Mismatch between Politics and Pedagogy

Sustainable educational leadership—leadership which leaves a legacy that lasts beyond the leader's professional lifetime—is very much in fashion nowadays. A recent edition of this journal was devoted entirely to the topic (Hargreaves 2005a). However, it is important to ensure that, together with leadership itself, the impact of leadership is sustainable. The self-aggrandizement, silver bullets, short-term big-bang approaches, procedural illusions, witch hunts, failures to communicate, and lack of accountability evident in the story of the building of the Swedish 17th century warship, the Vasa, do not sit well with sustainable and effective leadership. In this article, lessons learned from the Vasa are compared and contrasted with those put forward by the contributors to the recent themed edition of this journal. The authors then identify what they believe, on the basis of North American and international research evidence, to be the emerging priorities for sustainable and effective educational leadership.     

Making the case for a material-dialogic approach to science education

ABSTRACT

Science is concerned with understanding the world. As such, engaging with the materiality of that world is integral to both empirical experimentation and theorising within science. However, it has been recognised for some time that the way scientists learn about the world and the way that young people learn about science cannot be simply equated. This difference has been pronounced in recent decades by the dominance of constructivist and social-constructivist theories of learning, which focus on the development of concepts in the minds of people. Whilst these theories have yielded insight into the complexity of learning, the role of the material remains undertheorised, not only within practical science inquiry, but also in relation to the broader materiality of classrooms. Through a detailed critical literature review, this paper demonstrates the need for a stronger theoretical frame through which to understand the role of the material in the learning and pedagogy of science. Building upon the gaps and possibilities that this review reveals, we outline a new material-dialogic theory via a synthesis of Barad’s Agential Realism and Bakhtinian dialogic theory. The significance of this paper lies in offering a theoretical basis for more effective practice.     

Glutaraldehyde enhanced dielectrophoretic yeast cell separation

We introduce a method for improved dielectrophoretic (DEP) discrimination and separation of viable and nonviable yeast cells. Due to the higher cell wall permeability of nonviable yeast cells compared with their viable counterpart, the cross-linking agent glutaraldehyde (GLT) is shown to selectively cross-link nonviable cells to a much greater extent than viable yeast. The DEP crossover frequency (cof) of both viable and nonviable yeast cells was measured over a large range of buffer conductivities (22 μS∕cm–400 μS∕cm) in order to study this effect. The results indicate that due to selective nonviable cell cross-linking, GLT modifies the DEP cof of nonviable cells, while viable cell cof remains relatively unaffected. To investigate this in more detail, a dual-shelled oblate spheroid model was evoked and fitted to the cof data to study cell electrical properties. GLT treatment is shown to minimize ion leakage out of the nonviable yeast cells by minimizing changes in cytoplasm conductivity over a large range of ionic concentrations. This effect is only observable in nonviable cells where GLT treatment serves to stabilize the cell cytoplasm conductivity over a large range of buffer conductivity and allow for much greater differences between viable and nonviable cell cofs. As such, by taking advantage of differences in cell wall permeability GLT magnifies the effect DEP has on the field induced separation of viable and nonviable yeasts.     

The Skilled Counselor Training Model: Skills Acquisition,Self‐Assessment,and Cognitive Complexity

The authors evaluated the effectiveness of the Skilled Counselor Training Model (SCTM; M. H. Smaby, C. D. Maddux, E. Torres‐Rivera, & R. Zimmick, 1999) in teaching counseling skills and in fostering counselor cognitive complexity. Counselor trainees who completed the SCTM had better counseling skills and higher levels of cognitive complexity than did counselor trainees who did not receive the training. Before training, both experimental and control group participants overestimated their skills performance. The control group persisted in this overestimation after training, whereas students who completed the SCTM had a much more accurate self‐assessment. Results suggest that skills‐based training may improve counseling skills and cognitive complexity in counselor trainees.     

JUNIOR FACULTY AS LIAISONS: THE REALITIES OF PDS COLLABORATION

Conflicting perspectives on the parent’s role in the infant/toddler classroom can play a significant role in early educational settings. A recent ethnographic study of an Early Head Start program in New York City focused on conflict of this nature and raised the following set of questions: What sort of power and privilege should parents be given in decisions about classroom practice? Who or what should have the final say in these decisions: parents, teachers, administrators, or early childhood research literature? Should teachers unhesitatingly instruct parents as to what constitutes “best practice” or should the parents’ position be given primary consideration? How much weight should culturally based beliefs about child-rearing and early education carry in these decisions? The theoretical framework for this study, following Lubeck (1994) Lubeck, S. 1994. “The politics of developmentally appropriate practice: Exploring issues of culture, class and curriculum”. In Diversity and developmentally appropriate practices: Challenges for early childhood education, Edited by: Mallory, B. and New, R. 17–43. New York, NY: Teachers College Press.  [Google Scholar], challenges the notion that “disadvantaged” parents should be categorically dismissed as deficient in their thinking about what is educationally best for their children. The corollary notion that “disadvantaged” parents should be forced to defer to the assumptions of educators—most of whom are white and middle class—is similarly questioned. Greenman (1989) Greenman, J. 1989. Living in the real world: Diversity and Conflict. Exchange, 11 [Google Scholar] and Greenberg’s (1969 Greenberg, P. 1969. The devil has slippery shoes: A biased biography of the child development group of Mississippi (CDGM): A story of maximum feasible poor parent participation, Washington, DC: Youth Policy Institute.  [Google Scholar]/1991) assertions that conflicts that arise over teachers’, administrators’ and parents’ differing ideas about children, child-rearing, and early educational practice can be resolved in ways that are acceptable to all parties also inform this theoretical framework. An analysis of teacher interview data, coupled with classroom observational data, revealed four varying “theme perspectives.”     

Lost in translation? Emotional intelligence,affective economies,leadership and organizational change

Not until the late 1990s did the rational/emotional binary embedded in mainstream literature on educational leadership and management come under challenge. Now the emotional dimensions of organisational change and leadership are widely recognised in the leadership, organisational change and school improvement literature. However, the dissolution of the binary did not draw from feminist social theory, critical organisational theory, the sociology of emotions or critical pedagogy. Instead, the strongest influence in educational leadership and administration has been from psychological theory, management theory and brain science, mobilised particularly through Goleman's notion of emotional intelligence. This article undertakes a feminist deconstruction of two texts: one from organisational theory by Goleman and the other on educational leadership and school improvement, in order to explore how ‘emotion’ has been translated into educational leadership. As a counterpoint, I identify the gaps and silences, appropriations and marginalisation identified from feminist perspectives. I argue that the emotional labour of teaching and leading cannot be individualised because emotion is both relational and contextual.
