The Development of Object Permanence in Children with Intellectual Disability,Physical Disability,Autism, and Blindness

This article presents a review of the literature on object permanence with an emphasis on research on children with severe disabilities. Object permanence is the realisation that objects continue to exist in time and place even when they are no longer visible. This understanding is achieved across Stages IV(VI of Piaget’s Sensorimotor Period. Children with intellectual disability, physical disabilities, blindness, and autism develop object permanence in a similar sequence although at a slower rate than children without disabilities. Challenges with regulation make it difficult for children with autism to demonstrate object permanence knowledge in Stage VI tasks. There is ample evidence that children with severe disabilities benefit from direct and systematic instruction of object permanence. Assessment‐based instruction, establishment of visual attention, consideration of the characteristics of the object to be hidden (including the impact on differential attention), repeated naming of the object, individually appropriate prompting procedures, and direct reinforcement have been found to support mastery of object permanence in children with disabilities.     

Induction of newly qualified teachers in New Zealand

In this research, commissioned by the New Zealand Teachers Council, the quality of induction of provisionally registered teachers (PRT) (newly qualified) was examined utilising qualitative ‘success case studies’ within early childhood, primary, secondary, and indigenous Māori medium settings. The establishment of criteria for effective induction (from the literature and previous research) guided the identification of 20 ‘success’ sites across the sectors. In-depth data collection of each case was conducted via focus groups, one-to-one interviews and documentary analysis. The findings of the research highlighted exemplary induction practices across the sectors, with the most important associated with PRTs having access to a community, or ‘family’, of support during their induction. An interesting finding, which contrasted with previous research, was that PRTs in the secondary sector had levels of satisfaction with their role that were as high as those in other sectors. The key limitation to effectiveness was linked to lack of time for discussions and observations of the PRT's practice.     

A feel for the game – a Bourdieuian analysis of principal leadership: a study of Queensland secondary school principals

Educational leadership discourse has for sometime been the major intellectual pillar of what was once known as the field of educational administration. An examination of the postgraduate coursework programmes available to aspiring principal leaders at every Australian university supports such a contention. While this discourse does shed light on the ubiquitous concept of leadership, it does little to explain the context in which leadership theory is supposed to contribute to the operational environment of schools. This is where Bourdieuian scholarship is particularly helpful. By shedding light on the complex social space in which principal leaders function, Bourdieu’s concepts of habitus, field and capital are particularly helpful thinking tools. For a variety of reasons the economic field has held philosophical dominance for much of the last 30 years. This has impacted significantly on the work space of principal leadership and needs to be understood if the familiar narratives of leadership theory are to be of contextual use. When investigating the social space of contemporary principal leadership, my recent study of two sets of Queensland‐based principals will be used. The emergence of enterprise bargaining into the workspace of these principals will be used as a means by which to demonstrate the cross‐field contagion of the economic field on to the field of schools. The paper contends that the field of educational administration must endeavour to view leadership theory critically and contextually if the complexities associated with contemporary principal leadership practice are to be understood.     

Reading,learning and enacting: interpretation at visitor sites in the Wet Tropics rainforest of Australia

The northern Wet Tropics rainforest of Australia was declared a world heritage site in 1988 and now supports an extensive tourism industry that attracts an estimated 2.5 million local and international visits annually. As part of the visitor experience, many sites include both environmental and cultural interpretation experiences, which range from static displays to one‐on‐one guided tours. This paper identifies visitor demand and level of satisfaction with the static signage and displays used at rainforest sites throughout the Wet Tropics. The research involves visitor surveys conducted in 2007 and 2008 and observations at a number of rainforest sites. The results indicate that visitors consider the level of interpretation to be adequate, but appear to use it poorly. While higher at commercial sites, visitor interest in reading the interpretation is very low at public sites. Overall, this article seeks to address whether the aims of nature‐based interpretation, including education and the influencing of attitudes and site behaviour, are being achieved.     

A comparison of the agreement,internal consistency,and 2-day test stability of the InBody 720, GE iDXA,and BOD POD® gold standard for assessing body composition

The study compared the agreement, internal consistency, and measurement stability of the GE iDXA, BOD POD, and InBody 720. Body composition of 43 men and 37 women (31.4 ± 10.7 years; 90% Caucasian and 10% other) was assessed in triplicate using each method over two different days. Mean percent body fat (% BF) of the participants was different for all three machines (27.6 ± 10.0% [GE iDXA)] 25.6 ± 10.4% [BOD POD], and 21.3 ± 10.6% [InBody 720]; p < .05). The coefficient of variation for same day repeated measures was 1.06% (GE iDXA), 3.29% (BOD POD), and 2.97% (InBody 720). The coefficient of variation for 2-day repeated measures was 1.81% (GE iDXA), 4.61% (BOD POD), and 4.24% (InBody 720). The difference between the GE iDXA and BOD POD was within acceptable variability, while the InBody 720 significantly underestimated % BF. The internal consistency was highest for the GE iDXA, followed by the InBody 720, and then the BOD POD.     

Contribution of uncertainty in estimation of active drag using assisted towing method in front crawl swimming

Active drag force in swimming can be calculated from a function of five different variables: swim velocity, tow velocity, belt force, power output and exponent of velocity. The accuracy of the drag force value is dependent on the accuracy of each variable, and on the contribution of each variable to drag estimation. To calculate uncertainty in drag value, first the derivatives of the active drag equation with respect to each variable were obtained. Second, these were multiplied by the uncertainty of that variable. Twelve national age and open level swimmers were recruited to complete four free swimming and five active drag trials. The uncertainties for the free and the tow swim velocities, and for the belt force, contributed approximately 5–6% and 2–3% error, respectively, in calculation of drag. The result of the uncertainty of the velocity exponent (1.8–2.6) indicated a contribution of about 6% error in active drag. The contribution of unequal power output showed that if a power changed 7.5% between conditions, it would lead to about 30% error in calculated drag. Consequently, if a swimmer did not maintain constant power output between conditions, there would be substantial errors in the calculation of active drag.     

Environmental education in southern Africa: a case study of a secondary school in the Okavango Delta of Botswana

This study explored the extent to which teachers integrate environmental education and local environmental knowledge into the curriculum of a secondary school in the Okavango Delta of Botswana. In doing so, the study explored the potential value of place-based education in redressing concerns brought to light in postcolonial critiques of education in southern Africa. The study found that teachers sought to integrate environmental education into the curriculum through lessons that included references to local place names and local flora and fauna, lessons addressing issues related to environmental resource management in the region, and the acknowledgment and celebration of traditional lifestyle activities in the schools. The study also found that efforts to integrate environmental education into the curriculum were limited by a lack of educational resources needed to support these endeavors as well as a lack of adequate teacher training promoting this educational goal. The results also illustrate the potential value of place-based education in redressing the legacy of southern Africa’s colonial past in schools in Botswana and southern Africa.     

Novice mathematics teachers create themselves

This study presents a qualitative research based on three narratives written by novice mathematics teachers. We examine their unique professional world during their first year of work. The methodology of narrative framework, on which this article is based, helps to gain better understanding of the need for novice mathematics teachers to have pedagogical knowledge. Findings reveal three themes of pedagogical knowledge: the attitude of novice teachers toward students with difficulties in mathematics; parents’ expectations of and involvement with novice mathematics teachers; teacher–student relations. The implications of the findings show that novice mathematics teachers are required to have not only content knowledge of mathematics but also, and above all, pedagogical knowledge. The implications of this study enable reassessment of emphases required in training mathematics teachers, as well as the assistance and support they need, especially as they launch their careers.     

Back injuries and the fast bowler in cricket

Here, I review research that has investigated the aetiology of injuries experienced by adolescent and adult fast bowlers. Mechanical factors play an important role in the aetiology of degenerative processes and injuries to the lumbar spine. This is particularly so in fast bowling, where a player must absorb vertical and horizontal components of the ground reaction force that are approximately five and two times body weight at front-foot and rear-foot impact, respectively. Attenuated forces are transmitted to the spine through the lower limb, while additional foces at the lumbo-sacral junction are caused by trunk hyperextension, lateral flexion and twisting during the delivery stride. Fast bowlers are classified as side-on, front-on or mixed. The mixed action is categorized by the lower body configuration of the front-on action and the upper body configuration of the side-on technique. This upper body configuration is produced by counter-rotation away from the batsman in the transverse plane about the longitudinal axis of the body of a line through the two shoulders. Counter-rotations of 12–40° during a delivery stride have predicted an increased incidence of lumbar spondylolysis, disc abnormality and muscle injury in fast bowlers. During the delivery stride, the mixed bowling action also shows: more lateral flexion and hyperextension of the lumbar spine at front-foot impact, and a greater range of motion of the trunk over the delivery stride when compared with the side-on and front-on techniques. The pars interarticularis of each vertebra is vulnerable to injury if repetitive flexion, rotation and hyperextension are present in the activity. Fast bowlers should reduce shoulder counter-rotation during the delivery stride to reduce the incidence of back injuries. When a player is required to bowl for extended periods irrespective of technique, overuse is also related to an increased incidence of back injuries and must be avoided.
