Science Teacher Education in Brazil: 1950-2000

This paper analyzes the most significant events occurring in Brazil`s educational, social and political areas over the last half century, viewed against a background of relevant worldwide events. The hypothesis presented here is that the relations between the country`s educational policies, the demands of the various segments of academia, and the public school system have always been strained. This strain has contributed positively to the evolution of academic knowledge and production, to the design of more modern curricular projects by institutional authorities, and to the initial recognition of the specific construction of school knowledge by the school system itself. However, the interaction of these major institutions lacks a crucial element-one that would lead to an effective change in the education of science teachers and produce a positive impact on Brazil`s schools-namely, the wholehearted participation of science teachers themselves. With this analysis, we intend to contribute by offering some perspectives and proposals for science teacher education in Brazil.

Facilitation of learning in specialist nursing training in the PICU : the supervisors´ concerns in the learning situation

With the aim to unfold nurses’ concerns of the supervision of the student in the clinical caring situation of the vulnerable child, clinical nurses situated supervision of postgraduate nursing students in the Pediatric Intensive Care Unit (PICU) are explored. A qualitative approach, interpretive phenomenology, with participant observations and narrative interviews, was used. Two qualitative variations of patterns of meaning for the nurses’ clinical facilitation were disclosed in this study. Learning by doing theme supports the students learning by doing through performing skills and embracing routines. The reflecting theme supports thinking and awareness of the situation. As the supervisor often serves as a role model for the student this might have an immediate impact on how the student applies nursing care in the beginning of his or her career. If the clinical supervisor narrows the perspective and hinders room for learning the student will bring less knowledge from the clinical education than expected, which might result in reduced nursing quality.

Learners and their workplaces: towards a strategic model of flexible delivery of training in the workplace

Although the flexible delivery of training in the workplace has become a favoured policy position for training authorities in both Britain and Australia, this article reviews research that indicates neither learners nor their workplaces are well prepared. Drawing on the author's own research and that from the broader literature, the article develops a model for the preparation of learners and workplaces for flexible delivery of training. Deriving from the proposed model, the article suggests a wide range of strategies that may be used in preparing learners and workplaces for successful engagement with the flexible delivery of training.

Is it only 'what works' that 'counts' in new knowledge economies? Evidence-based practice, educational research and teacher education in Australia

Recent texts on globalisation and education policy refer to the rapid flow of education policy texts producing or responding to common trends across nation states with the emergence of new knowledge economies. These educational policies are shaping what counts as research and the dynamics between research, policy, and practice in schools, creating new types of relationships between universities, the public, the professions, government, and industry. The trend to evidence-based policy and practice in Australian schools is used to identify key issues within wider debates about the ‘usefulness’ of educational research and the role of universities and university-based research in education in new knowledge economies.

Developing preparedness for flexible delivery of training in enterprises

On a basis of research and literature review, Smith, in 2001, suggested a model for the development of preparedness of learners and their workplaces to support the flexible delivery of training in enterprises. Using the model as a framework, he then developed a detailed set of strategies that may be used in operating workplaces to develop learners and workplaces for effective flexible delivery. The research reported here was designed to test that strategy set in 12 different enterprises to assess the feasibility of their implementation in operating workplaces. The research shows that a majority of suggested strategies are feasible for implementation; some are feasible with qualification; and a minority were not seen as feasible.

Specialist training in investigative and evidential interviewing: is it having any effect on the behaviour of professionals in the field?

While numerous concerns have been voiced over the past decade regarding the inappropriate question styles of investigative and evidential interviewers, there has been relatively little research, discussion, and critique in relation to the content, structure, and efficacy of existing interviewer training courses. This article provides a brief up-to-date summary of the essential elements of an investigative or evidential interview, followed by a review of research relating to the effectiveness of training programs for forensic interviewers and the factors that are needed to promote the use of appropriate questioning techniques. Finally, this article offers recommendations for future research and for the revision of existing training programs in forensic interviewing.

A knowledge-based economy landscape: implications for tertiary education and research training in Australia

This paper discusses the higher education sector’s role in knowledge-based economy though research training, that is, doctoral education. It also examines how a Faculty of Education supports its doctoral candidates in their endeavours to become ‘knowledge producers’. Two themes are explored: one is Australia’s limited investment in education by international standards; and the other is the research training needs and circumstances of doctoral candidates who are located in professional and workplace contexts. The paper discusses the role of online support and a Doctoral Studies in Education (DSE) online seminar program to support primarily off-campus, part-time mid-career professionals. These are typical of many of Australia’s doctoral candidates. E-learning is examined as part of a comprehensive support and research training strategy for doctoral candidates studying at a distance. We discuss the sorts of opportunities and experiences our candidates receive and the extent to which they are readied to work effectively in a knowledge-based economy.

Endurance training in humans leads to fiber type-specific increases in levels of peroxisome proliferator-activated receptor-[gamma] coactivator-1 and peroxisome proliferator-activated receptor-[alpha] in skeletal muscle

The peroxisome proliferator-activated receptor (PPAR)-γ coactivator-1 (PGC-1) can induce mitochondria biogenesis and has been implicated in the development of oxidative type I muscle fibers. The PPAR isoforms α, β/δ, and γ control the transcription of genes involved in fatty acid and glucose metabolism. As endurance training increases skeletal muscle mitochondria and type I fiber content and fatty acid oxidative capacity, our aim was to determine whether these increases could be mediated by possible effects on PGC-1 or PPAR-α, -β/δ, and -γ. Seven healthy men performed 6 weeks of endurance training and the expression levels of PGC-1 and PPAR-α, -β/δ, and -γ mRNA as well as the fiber type distribution of the PGC-1 and PPAR-α proteins were measured in biopsies from their vastus lateralis muscle. PGC-1 and PPAR-α mRNA expression increased by 2.7- and 2.2-fold (P < 0.01), respectively, after endurance training. PGC-1 expression was 2.2- and 6-fold greater in the type IIa than in the type I and IIx fibers, respectively. It increased by 2.8-fold in the type IIa fibers and by 1.5-fold in both the type I and IIx fibers after endurance training (P < 0.015). PPAR-α was 1.9-fold greater in type I than in the II fibers and increased by 3.0-fold and 1.5-fold in these respective fibers after endurance training (P < 0.001). The increases in PGC-1 and PPAR-α levels reported in this study may play an important role in the changes in muscle mitochondria content, oxidative phenotype, and sensitivity to insulin known to be induced by endurance training.

The scholarship of teaching: risky business in ICT education

The idea of the scholarship of teaching was reinvigorated twelve years ago by Boyer's (1990) book, Scholarship reconsidered: Priorities of the professoriate. Since then a considerable body of literature has developed, discussing what the scholarship of teaching might look like, why it is desirable and how it might be encouraged. The scholarship of teaching has been described as including the activities involved in designing, implementing and evaluating teaching and learning, and associated dissemination activities. Over the last few years there has been a resurgence of interest in the role that scholarship might play in the promotion, recognition and reward of good university teaching.

This paper draws on qualitative data that were collected as part of a national study of the major university discipline of Information and Communication Technology (ICT) to generate a framework for describing the context of university teaching and for examining how conducive this context is to the scholarship of teaching. The framework comprises two domains: that of the individual educator and that of the organisational environment in which the educator works. The paper highlights the importance of, and interaction between, these domains, and the role they play in promoting or discouraging the scholarship of teaching.

A proposal for change to teacher education in and for rural and regional Australia

In recent years, much attention has been given to the preparation of teachers for rural and regional schools (for example, Marks et al, 2000, Marks et al, 2001, Jones, 2002). Rural and regional teacher education brings with it exciting opportunities for individuals and communities. However, it is also coupled with specific demands on governments, teaching staff and tertiary institutions. However, as yet little attention has been given to how to reform teacher education to address the identified issues (Green & Reid, 2004). At present, the teacher education course offered on the Warrnambool campus of Deakin University is identical to that offered on the metropolitan (Burwood) and regional (Geelong) campuses. The course is a traditional four-year course.

At the Warrnambool campus we are embarking on a project which aims to reconceptualise teacher education for rural and regional contexts. It seeks to: better understand the issues and challenges rural and regional stake holders face within the profession, including both pre-service and service dimensions; identify the context specific knowledge, skills and strategies rural and regional schools are looking for in graduate teachers; and develop and implement a revised Bachelor of Education program that reflects the needs of rural and regional education.

In this paper, we outline how we intend determining the demand for a community-based teacher education program in western Victoria and determining/negotiating community support for such an initiative.
