Forearm blood flow in individuals with CHF and age-matched healthy volunteers : a study and historical review

This study examined forearm blood flow (FBF) in individuals with chronic heart failure (CHF) at rest, moderate exercise, and following limb occlusion. FBF was measured by venous occlusion plethysmography in CHF patients (n = 43) and healthy age-matched volunteers (n = 8) at rest and during exercise consisting of intermittent isometric hand squeezing at 15, 30, and 45% of maximum voluntary contraction (MVC). Peak vasodilatory capacity was also determined following the release of an occluding arm cuff. FBF was lower in CHF patients during exercise and during peak reactive hyperemia (PRH) compared to healthy volunteers, but there was no significant difference between groups at rest. Peak vasodilatory capacity was significantly higher in healthy volunteers than the CHF group ((30.6 ± 8.6 ml±100 mL^-1±min^-1 and 18.3 ± 6.9 ml±100 mL^-1±min^-1, respectively). Local blood flow stimulation in response to exercise or limb occlusion is reduced in individuals with CHF, however, there was no difference in resting flows between the two groups, suggesting vasodilatory medication may restore resting blood flow to healthy values.

The principles of learning and teaching (PoLT)

In Victoria, Australia, under the Blueprint agenda, The Principles of Learning and Teaching (Department of Education and Training, 2005) are being used to operationalise pedagogical change and curriculum renewal. The University of Melbourne is one of the three contracted providers and in 2005 and 2006 has supported 450 teachers from state, independent and special schools in Victoria and 70 teachers in Singapore. The paper outlines the workings of the model and illustrates how through a deeper and renewed focus on pedagogy schools are being asked to examine and change their practice for all students. One benefit of the initiative is that special schools are an integral part of the cluster network and are reconsidering their role in school renewal and systems transformation more broadly. However the regime of pedagogical renewal must be understood as part of the past and the present, multiple transgressions and intense struggles in reform practices more broadly. None the least being the persistent stratification of schooling into special and regular in the Victorian context and professional learning being constructed as weak professional socialization. Working visually and reading intertextually undoing some of the problematics of the implementation process the challenges of system wide professional learning and curriculum reform are exposed.

People and environment : the outdoor education community : curriculum ideas

This session is based on the concept of people as part of a broad ecological community. It focuses on relationships between people and between people and their environment. We look at outdoor education curriculum and teaching ideas aimed at developing the concepts of community, interdependence and responsibility for people and other living and non-living things. The concepts will be discussed in relation to developing outdoor education programs for students in years Prep-10.
Examples of teaching and assessment ideas will be provided from the Outdoor Education Course Advice Materials which have been developed for the Victorian Curriculum and Standards Framework (CSF). Resources will also be discussed and displayed. The session will be part presentation and part interactive group work. It is relevant to teachers, curriculum developers and other outdoor educators working with children in the years Prep-10 age range.

Teaching secondary school mathematics : research and practice for the 21st century

For the last decade or so, educational policy makers and researchers in many countries have been calling for significant changes to the way mathematics is taught in secondary schools. Australian mathematics curriculum documents now promote learning goals that go beyond mastery of a pre-determined body of knowledge and procedures - the traditional emphasis on facts, skills, formulae - to include mathematical reasoning and problem solving, communication, and real world applications. There is also pressure to move away from over-reliance on teacher-centred practices such as exposition and individual seatwork, towards activities that promote learners' involvement in constructing, applying, and evaluating mathematical ideas. Further impetus for reform comes from research recommending that if learners are to develop mathematically powerful forms of thinking and habits of mind, then classrooms should immerse them in the authentic practices of the discipline by supporting a culture of collaboration and sense-making. Teaching Secondary School Mathematics - incorporates recent developments in research and practice and applications to teaching mathematics in Australian secondary schools. Covering such areas as curriculum, pedagogy and assessment; teaching mathematical content; equity and diversity in the classroom; and professional and community engagement, it is an invaluable resource for all practising and pre-service mathematics teachers.

Growth of pre-service teachers’ knowledge and teaching ideas about decimals and fractions : The case of Vivi

This paper discussed and analysed the growth of one pre-service teachers’ knowledge about decimals and fractions during a teaching experiment. Evidence of her progress is based on responses to written test and interview questions. This case shows with probing questions and appropriate teaching ideas, it is possible for a pre-service teacher with initially weak and fragmented knowledge about decimals and fractions to develop a meaningful knowledge about decimals and fractions. The stronger conceptual base provided by use of a concrete representation of decimals enabled Vivi to move away from reliance on memorised facts and rules and towards conceptually based explanations of ideas.

Australian women in education : 2012 and still blocked at the pass. Is there a remedy?

Women have been striving for equity and diversity for a long time. Despite enormous changes in Australian women’s lives over the past five decades, there are glaring ‘sticking points’ – in education and social life in general - that are proving resilient to change. This keynote addresses some of these issues and canvasses what might be needed to tackle them.

Concurrent undergraduate study and industry employment - the Australian experience

Undergraduate education in Quantity Surveying (QS) and Construction Management (CM) in Australia has traditionally incorporated concurrent industry experience as an important requisite prior to graduation. This has been primarily driven by accrediting professional associations but most universities have also recognized the value of this cooperative approach to education with industry. However, in recent years many universities have become concerned about the amount of time that students are spending in industry employment to the point where, for some students, their employment takes precedence over their academic studies. Past research has shown that working long hours has a negative effect on the study patterns of undergraduate students. This paper presents the results of research undertaken to examine the amount of time that Quantity Surveying and Construction Management students actually spend engaged in paid work during semester time and the impact on their studies. The methodology for the research was based on two separate questionnaire surveys distributed to undergraduate Quantity Surveying and Construction Management students at 7 universities across Australia. The questionnaires focused on the nature and extent of their paid work while enrolled in full-time study. The results indicate that students in the early stages of their program tend to undertake casual work that is not related to their degree but move to construction industry employment in the later stages of their program. The research found that students were spending an average of 18 hours per week in industry employment with this average increasing to over 23 hours in their final year. A number of students were spending well over 30 hours per week in industry employment. The implications of the extent of this concurrent industry employment are discussed.
