The Development of Nonsymbolic Probability Judgments in Children

Two experiments were designed to investigate the developmental trajectory of children's probability approximation abilities. In Experiment 1, results revealed 6- and 7-year-old children's (N = 48) probability judgments improve with age and become more accurate as the distance between two ratios increases. Experiment 2 replicated these findings with 7- to 12-year-old children (N = 130) while also accounting for the effect of the size and the perceived numerosity of target objects. Older children's performance suggested the correct use of proportions for estimating probability; but in some cases, children relied on heuristic shortcuts. These results suggest that children's nonsymbolic probability judgments show a clear distance effect and that the acuity of probability estimations increases with age.     

Testing the application of corrective adjustment procedures for removal of relative age effects in female youth swimming

ABSTRACT

The purpose of this study was (1) accurately estimate longitudinal relationships between decimal age (i.e., chronological and relative) and performance in Australian female 100 m (N = 765) and 200 m (N = 428) Breaststroke swimmers (10–18 years); and (2) determine whether corrective adjustment procedures could remove Relative Age Effects (RAEs) in an independent sample of age-matched 100 m (N = 2,491) and 200 m (N = 1,698) state/national level Breaststroke swimmers. In Part 1, growth curve modelling quantified longitudinal relationships between decimal age and swimming performance. In Part 2, relative age distributions (Quartile 1–4) for “All”, “Top 25%” and “10%” of swimming times were examined based on raw and correctively adjusted swim times for age-groups. Based on raw swim times, finding identified RAE effect sizes increased in magnitude (small-medium) with selection level (“All”-“Top 25%”) in 12–14 years age-groups for both events. However, when correctively adjusted swim performances were examined, RAEs were primarily absent across all age-groups and selection levels. Using longitudinal reference data, corrective adjustment procedures removed relative age advantages in female youth Breaststroke performance. Removing the influence of relative age-related differences is predicted to improve the accuracy of identifying genuinely skilled youth swimmers.     

Embracing the Open-Source Movement for the Management of Spatial Data: A Case Study of African Trypanosomiasis in Kenya

The past decade has seen an explosion in the availability of spatial data not only for researchers, but the public alike. As the quantity of data increases, the ability to effectively navigate and understand the data becomes more challenging. Here we detail a conceptual model for a spatially explicit database management system that addresses the issues raised with the growing data management problem. We demonstrate utility with a case study in disease ecology: to develop a multi-scale predictive model of African Trypanosomiasis in Kenya. International collaborations and varying technical expertise necessitate a modular open-source software solution. Finally, we address three recurring problems with data management: scalability, reliability, and security.     

Value creation in online communities for educators

The popularity and pervasiveness of online communities have led researchers and practitioners alike to closely examine the utility of online communities for supporting and facilitating professional learning. As economic constraints leave fewer resources available for professional development, educators in particular are examining the potential of online communities to enhance and extend traditional professional development opportunities. Leveraging the potential of online communities requires an in‐depth understanding of the value that members find through their participation. This study used Wenger, Trayner and de Laat's value creation framework to better understand cycles of value creation in online communities. Findings illuminate how members with varying perspectives and levels of expertise co‐construct new forms of meaning and understanding in ways that are individually and collectively valuable, and how they apply that knowledge to their professional practice. Additionally, the study offers insight into the ways in which actions of community leaders and a sponsoring organization support and facilitate value creation through different types of activities, tools and interactions.     

A study on the attitudes and experiences of chairpersons in American Criminology and Criminal Justice Programs

Building on Todd Clear’s () recent declaration that academic criminal justice has come of age, this study examines chairs in American criminology and criminal justice programs. By way of survey, chairpersons (n?=?78) randomly selected from programs across the United States were questioned in a number of areas related to their positions. The study finds that chairs in these programs are struggling with the same concerns as chairs in other academic disciplines (i.e., competing roles and job‐related stress). As such, while many of them are fairly satisfied with their positions, most of them plan on returning to the faculty once their term is completed. Based on the results of the research, there were two clear implications. First, because of the onerous time demands, young scholars are to be discouraged from taking on significant administrative responsibilities until they have been promoted, tenured, and have achieved some level of accomplishment within the discipline. Second, scholars who are currently chairs and have ambitions of moving through the administrative ranks should be encouraged to do so. As more criminologists progress through the administrative ranks, it is anticipated that the discipline will be viewed and treated more favorably within American universities.     

Plantwise knowledge bank: delivering plant health information to developing country users

The Plantwise knowledge bank is an open access, online resource that provides information to users involved in plant health systems in the developing world. The challenge was to deliver dependable information that could serve users with widely differing needs and understanding and to get actionable knowledge to subsistence farmers in particular. This was met by bringing together resources across CABI, particularly by supplementing core publishing capabilities with the knowledge, skills and understanding of the internationally based scientific staff and their network of collaborators. An iterative development process, with scoping, wireframes and prototype delivery, was undertaken with constant feedback from global users. Content needed to be repurposed from CABI's own databases, brought in from international partners and freshly created, and then delivered to each user in a structure that was easy to navigate and had easy‐to‐use tools to add value. The product has been widely well received and ongoing development will be guided by lessons learned and new requirements as the Plantwise programme expands.     

How Measurement and Modeling of Attendance Matter to Assessing Dimensions of Inequality

ABSTRACT

Each iteration of high stakes accountability has included requirements to include measures of attendance in their accountability programs, thereby increasing the salience of this measure. Researchers too have turned to attendance and chronic absence as important outcomes in evaluations and policy studies. Often, too little attention is paid to the implications of measurement or statistical modeling decisions employed in these studies. Such lack of attention to measurement and modeling can obscure important differences in these measures across the educational life cycle, as well as between the outcomes of higher income students and their lower-income peers. Using longitudinal data from a representative state, this paper demonstrates how measurement and modeling choices can influence model estimates and undermine the quality of inferences. These considerations have important implications for researchers and practitioners who wish to use attendance data to understand policy impacts and guide practice, particularly when focused on chronic absence.     

Identifying pedagogy and teaching strategies for achieving nationally prescribed learning outcomes

With the globalisation of university education, national frameworks are commonly used to prescribe standardised learning outcomes and achieve accountability. However, these frameworks are generally not accompanied by guiding pedagogy to support academics in adjusting their teaching practices to achieve the set outcomes. This paper reports the results of a scoping review of health science literature aimed at identifying pedagogy and teaching strategies relevant to achieve the learning outcomes specified by the Australian Qualifications Framework at a master's degree level. Eight practical teaching messages emerged from the review and three broad pedagogical trends were identified: the need to use authentic disciplinary-based learning activities; ensure that students are able to discover different perspectives about future practice and bring student reflection about their own knowledge into curricula. More critically, the review highlights that academics attempting to translate national learning outcome frameworks into their teaching practices face a complex and time-consuming task which may involve searching beyond their own disciplinary focus to identify practical teaching strategies to meet prescribed learning outcomes.     

Globalizing policy sociology in education: working with Bourdieu

This paper uses Bourdieu to develop theorizing about policy processes in education and to extend the policy cycle approach in a time of globalization. Use is made of Bourdieu’s concept of social field and the argument is sustained that in the context of globalization the field of educational policy has reduced autonomy, with enhanced cross‐field effects in educational policy production, particularly from the fields of the economy and journalism. Given the social rather than geographical character of Bourdieu’s concept of social fields, it is also argued that the concept can be, and indeed has to be, stretched beyond the nation to take account of the emergent global policy field in education. Utilizing Bourdieu’s late work on the globalization of the economy through neo‐liberal politics, we argue that a non‐reified account of the emergent global educational policy field can be provided.
