The use of video recording in professional development of teachers and teacher educators in Indonesia

Design-based research has gained currency in educational research over the past decade due to its strength to bridge the divide between theoretical research and educational practice in naturalistic settings. Design based approaches involve a process of designing mathematical tasks, observing the enacted design in classrooms and reflecting on the process from analysing the classroom artifacts. Video plays a central role in supporting teachers and teacher educators to study and reflect on students’ mathematical thinking and in capturing the dynamic of classroom teaching and learning process.

This chapter will examine and analyse practitioner’s lenses in capturing the dynamic and complexity of classroom mathematical learning using video segments, and classroom artifacts including digital photos of classroom moments and students’ work. Practitioners’ lenses are taken as a window to capture key teaching and learning moments from the lessons. Analysis of this selection of these video segments along with other classroom artifacts based on practitioners’ lenses provide insights into practitioners’ views on key teaching and learning moments in mathematics lessons.

The relationship between the incidence of medullated fibres in mohair and live weight over the lifetime of Angora goats

The presence of even a small amount of medullated fibre, in otherwise high quality mohair, may have a pronounced adverse effect on its value and end-use potential. However, there is considerable confusion about the effects, if any, of environmental variables and management upon the incidence of medullated fibres in mohair. This study examined how the incidence of medullated fibres (Med, % by number) is related to the fleece-free live weight (FFLwt) of Angora goats of different genetic origins over their lifetime, and how the relationship varies with other lifetime factors. Measurements were made over 11 shearing periods of 6 months, on a population of Angora goats representing the current range and diversity of genetic origins in Australia, including South African, Texan and interbred admixtures of these and Australian sources. Records of breed, sire, dam, date of birth, dam age, birth weight, birth parity, weaning weight, live weight, fleece growth and fleece quality were taken for castrated males (wethers) (n = 94 animals). A restricted maximum likelihood (REML) model was developed for log10(Med + 1), which allowed the observations of the same animal at different ages to be correlated in an unstructured manner. Med varied between 0.1% and 4.3%. The median average FFLwt during a shearing interval increased from 15 kg at 1 year old to 59 kg at 6 years old. Generally, within each shearing interval, Med increased with increasing average FFLwt. However, the size and shape of the relationship differed greatly between shearing ages. For example, at 3.5 years of age Med increased from about 1.1% at an average FFLwt of 26 kg to 2.6% at 50 kg, whilst at 5.0 years of age Med only changed from 1.4% at 32 kg to 1.6% at 56 kg. Goats with mixed genetic parentage showed an increase in Med at some shearings, particularly at younger ages. Variation in animal nutrition, as measured by live weight change during shearing periods, did not affect Med. The results supplement our earlier findings that mohair mean fibre diameter and clean mohair fleece weight, but not staple length, are greater in larger Angora goats. Live weight needs to be taken into account in genetic evaluation of the incidence of medullated fibres. We conclude that any advantage in handling fewer but larger Angora goats rather than more but smaller goats will come at the detriment of producing lower quality mohair, both in terms of increased Med and mean fibre diameter.

Learn from yesterday, live for today, hope for tomorrow : attempting to plan for coastal change in South West Victoria

Learn from yesterday, live for today hope for tomorrow. When Albert Einstein penned these opening words, the realm of planning was least on his mind despite the aptness of the thoughts. This paper, having regard to this quotation, questions whether demographic change in one coastal area is occurring at a faster rate than in non–coastal areas? The South West coastal area of Victoria, from 1981 onwards, has witnessed a dramatic increase in population and also major shifts in the social and economic characteristics of the region. What have been the historic demographic and employment characteristics of the area and has there been a shift in these characteristics leading to the rapid population growth? These questions are considered using the City of Warrnambool, the largest urban centre in South West Victoria, as a study vehicle. The impact of a growing population on the municipal landscape can be demanding in terms of land use planning, land supply and the urban design. This paper will review the population growth using a shift share analysis method compared against overall growth patterns in the Victorian state population and Australia overall. It will then examine government population forecasts for the City of Warrnambool and suggest those impacts upon the current City of Warrnambool landscape.

Presents//presence: Telematics, performance and embodiment

Of giving and receiving // Of giving and taking // Of exchanges
Reciprocity // Mutuality // Expectations

A performance of liveness in which the presence of the performer is interrogated.

Drawing on Dan Graham's (1974) Two Consciousness Project, Presents//Presence plays on Object = Space relationships. Engaging with contemporary notions of thinking and consciousness, the performance plays with time - the here and now, the passage of time, time zones, and timing.

Lovers. An anniversary. Fine Dining. Distance. Skype.

Presents disrupt subject positions of audience, of performer; something happens while we are waiting for something else to happen. Through the use portable computers and hand-held (smart) devices for the capture and 'projection' of action in real time, the exploration sets out to engage with notions live and remote, absence and presence, the play of embodied transmission and live performance and the perception of absence.

Through a simulation of the simultaneous presences (performances) of performers Magda Miranda and Rea Dennis, Presents//Presence is a performative event that (re) activates live/d moments in the lives of the artists. Such presence characterizes computer time – “a permanent present, an unbounded, timeless intensity” (Virilio in Dixon 90). Such presence could also be said to characterize the intra-subjective experience of intimacy. The piece draws on the languages of live theatre, elements of autobiographical performance, inter- and intra-subjective perception, and an understanding of time as a spatial metaphor. This paper reports on the performance event Presents//Presence. In it, we outline the narrative and structural anchors that frame the piece and discuss some of the theoretical threads informing the research. The paper is accompanied by a recording of the performance that was delivered to a live audience at University of South Wales, Cardiff during the Remote Encounters conference in April 2013.

‘Stanley Schupak doesn’t live here anymore’: un/becoming transsexual and coming home in Duncan Tucker’s Transamerica

This article analyses the representation of male-to-female transsexuality as represented in Duncan Tucker's film Transamerica (2005). Using a combination of transgender theory and textual analysis this article argues that there is a normativising agenda in this film that makes transsexuality pallatable for non-transgender (or cisgender) audiences by aligning it with idealised (and conservative) conventions in Western culture for women, those of motherhood, heterosexuality, and family-centricity.
