The diagrams of fraction-walls, and beyond, may be useful aids for teaching those fascinating topics of fractions, and their cousins decimals and percentages.

Fractions are different from other numbers: they need new ways of working - right? No. That’s a recipe for relying on unexplainable rote rules. Fraction calculations are sensibly based in properly understood whole-number operations. If we really know how to multiply and divide (and add and subtract) whole-numbers, doing the same kinds of things with fractions will be easy, and memorable. But how does this fit with VELS and Progression Points? What is the Fraction Curriculum, and how could we teach it?

In this paper images are used to support the conceptualisation and recognition of embodied pedagogy. Analysis of data gathered during an arts-based teaching project in pre-service teacher education revealed the presence of an embodied pedagogy and supports the further deployment of embodied teaching and learning in teacher education. Embodied pedagogy includes embodied teaching and embodied learning but is conceptualised through ‘pedagogy as relational’ – between teaching and learning and between teacher and learner. Through image this paper presents traces of embodied pedagogy from the classroom. These tracings of embodied pedagogy in classrooms defy baseline certainty and instead assert Benjamin’s thesis that knowledge can only ‘stand up’ through multiplicity, through all acts of knowing.

This presentation draws on the observations and experiences that we, as teacher educators, have had using Teaching Games for Understanding (TGfU) as a pedagogical tool with generalist pre-service teachers in two different sites: Malaysia and Australia. TGfU is a game-centred pedagogy in which students learn the „Why‟ of game playing before the „How‟ of the skills associated with the game. This concept is based on a student-centred approach to learning. The benefit of this pedagogy to generalist teachers is the notion that they are not required to be a master of many sports. This narrative relates the observations and experiences of teacher educators of Malaysian and Australian generalist pre-service teachers confronted with teaching and learning TGfU for the first time in their culturally specific contexts. The two key issues arising from teaching the TGfU model were: the disparity in the cohorts‟ experiences arising from institutionalised conceptions by the pre-service teachers of what and how learning occurs in physical education; and the pre-service teachers‟ difficulty with implementing the TGfU model in a practical situation. Crossing the cultural divide for the Malaysian and Australian pre-service teachers required them to explore more fully the range of approaches to teaching and to recognise a more student-centred approach as a valid and authentic tool. As both teachers and observers of this process, our intention was to examine the two cohorts‟ learning and subsequent teaching with the aim of developing better understandings of the challenges when teaching TGfU in tertiary settings.

The emotional intelligence of educators has a major influence on how well they are able to help people to learn. Teachers with high levels of emotional intelligence always or usually adopt an appropriate emotionally intelligent response in both positive and negative situations. Teachers with low levels of emotional intelligence sometimes adopt an emotionally intelligent response in positive situations but seldom or never in negative situations. These differences have some significant implications. The authors' research shows that emotional intelligence and self-efficacy are different but related concepts. A teacher's level of emotional intelligence is linked to his or her sense of self-efficacy. A teacher with high levels of emotional intelligence is more likely to be able to work more effectively and persist longer because they have a belief in their own ability and feel that they are in control. The emotionally intelligent teacher is sensitive to his or her own emotions and the emotions of others and so is able to build positive relationships with colleagues and students. Beyond that, a teaching environment that is emotionally healthy and supportive will enhance the development of teachers' emotional intelligence.

Evidence from epidemiologic studies that central obesity precedes future metabolic change and does not occur concurrently with the appearance of the blood pressure, glucose, and lipid abnormalities that characterize the metabolic syndrome (MetS) has been lacking. Longitudinal surveys were conducted in Mauritius in 1987, 1992, and 1998, and in Australia in 2000 and 2005 (AusDiab). This analysis included men and women (aged 25 years) in three cohorts: AusDiab 2000–2005 (n = 5,039), Mauritius 1987–1992 (n = 2,849), and Mauritius 1987–1998 (n = 1,999). MetS components included waist circumference, systolic blood pressure, fasting and 2-h postload plasma glucose, high-density lipoprotein (HDL) cholesterol, triglycerides, and homeostasis model assessment of insulin sensitivity (HOMA-S) (representing insulin sensitivity). Linear regression was used to determine which baseline components predicted deterioration in other MetS components over 5 years in AusDiab and 5 and 11 years in Mauritius, adjusted for age, sex, and ethnic group. Baseline waist circumference predicted deterioration (P < 0.01) in four of the other six MetS variables tested in AusDiab, five of six in Mauritius 1987–1992, and four of six in Mauritius 1987–1998. In contrast, an increase in waist circumference between baseline and follow-up was only predicted by insulin sensitivity (HOMA-S) at baseline, and only in one of the three cohorts. These results suggest that central obesity plays a central role in the development of the MetS and appears to precede the appearance of the other MetS components.
