The Choice of Response Probability in Bookmark Standard Setting: An Experimental Study

Evidence of the internal consistency of standard-setting judgments is a critical part of the validity argument for tests used to make classification decisions. The bookmark standard-setting procedure is a popular approach to establishing performance standards, but there is relatively little research that reflects on the internal consistency of the resulting judgments. This article presents the results of an experiment in which content experts were randomly assigned to one of two response probability conditions: .67 and .80. If the standard-setting judgments collected with the bookmark procedure are internally consistent, both conditions should produce highly similar cut scores. The results showed substantially different cut scores for the two conditions; this calls into question whether content experts can produce the type of internally consistent judgments that are required using the bookmark procedure.     

Automatic detection of collisions in elite level rugby union using a wearable sensing device

Elite rugby union teams currently employ the latest technology to monitor and evaluate the physical demands of training and games on their players. Tackling has been shown to be the most common cause of injury in rugby union, yet current player monitoring technology does not effectively evaluate player tackling measurements. Currently, to evaluate measurements specific to player tackles, a time-consuming manual analysis of player sensor data and video footage is required. The purpose of this work is to investigate tackle modeling techniques which can be utilised to automatically detect player tackles and collisions using sensing technology already being used by elite international and club level rugby union teams. This paper discusses issues relevant to automatic tackle analysis, describes a technique to detect tackles using sensing data and validates the technique by comparing automatically detected collisions to manually labeled collisions using data from elite club and international level players. The results of the validation show that the system is able to consistently identify collisions with very few false positives and false negatives, achieving a recall and precision rating of 0.933 and 0.958, respectively. The aim is that the automatically detected tackles can provide coaching, medical and strength and conditioning staff with objective tackle-specific measurements, in real time, which can be used in injury prevention and rehabilitation strategies.     

Designing informal learning experiences for early career academics using a knowledge ecosystem model

This article presents a ‘knowledge ecosystem’ model of how early career academics experience using information to learn while building their social networks for developmental purposes. Developed using grounded theory methodology, the model offers a way of conceptualising how to empower early career academics through (1) agency (individual and relational) and (2) facilitation of personalised informal learning (design of physical and virtual systems and environments) in spaces where developmental relationships are formed, including programmes, courses, events, community, home and social media. It is suggested that the knowledge ecosystem model is suitable for use in designing informal learning experiences for early career academics.     

Does Dampened Physiological Reactivity Protect Youth in Aggressive Family Environments?

Is an attenuated physiological response to family conflict, seen in some youth exposed to early adversity, protective or problematic? A longitudinal study including 54 youth (average age 15.2 years) found that those with higher cumulative family aggression exposure showed lower cortisol output during a laboratory‐based conflict discussion with their parents, and were less likely to show the normative pattern of increased cortisol reactivity to a discussion they rated as more conflictual. Family aggression interacted with cortisol reactivity in predicting youth adjustment: Adolescents from more aggressive homes who were also more reactive to the discussion reported more posttraumatic stress symptoms and more antisocial behavior. These results suggest that attenuated reactivity may protect youth from the negative consequences associated with aggressive family environments.     

Examining the effect of multiple writing tasks on Year 10 biology students’ understandings of cell and molecular biology concepts

This paper reports on a study that examined the cumulative effects on students’ learning of science, and perceptions of the role of writing in learning, when the students engaged in multiple writing tasks with planning strategy support. The study was conducted with Year 10 biology students who completed two consecutive units on Cells and Molecular Biology. A mixed method study was implemented using a pre-/post-test design with a focus on student performance on higher order conceptual questions, and semi-structured interviews with treatment students after the completion of each unit of study. Results from the quantitative component indicated that multiple, non-conventional writing had a significant benefit in helping students learn Molecular Biology. The results for the Cell unit were not so conclusive suggesting the strategies are most useful for novel content. The interviews with students demonstrated that they understood and engaged successfully with both the conceptual and linguistic demands of the tasks. These findings, taken as a whole, confirm that multiple writing tasks can support effective student learning, provided various pedagogical conditions are met.     

Relation between reading problems and internalizing behavior in school for preadolescent children from economically disadvantaged families

This longitudinal study of 105 economically disadvantaged children examined the relation between reading problems and internalizing behavior in 3rd- and 5th-grade assessments (8- to 12-year olds). The variable-centered results showed that reading problems predicted change in internalizing behavior in the context of child and family predictors. The person-centered results showed that children with reading problems in both grades had higher internalizing scores in 5th grade but not in 3rd grade than children with reading problems in 3rd grade or no problems. Child-reported negative emotion experiences varied similarly across grade. The results tie reading problems to emotional distress in school and support conclusions about the direction of effects and the internalization of academic difficulty for disadvantaged children.     

Māori science education in Aotearoa New Zealand

Abstract    This article reports on the first two phases of a multiphase science education development project in predominantly Māori kura (school communities) in the central region of the North Island of Aotearoa New Zealand. The development project in its entirety employs an action research methodology and by so doing endeavors to support the improvement of science education delivery in accordance with school community aspirations. The full project (a) establishes the current situation in Year 1–8 science education in the communities; (b) identifies developmental aspirations for stakeholders within the communities and identifies potential contributors and constraints to these aspirations; (c) implements mechanisms for achieving identified aspirations; and finally; (d) evaluates the effectiveness of such mechanisms. In its focus on the first two phases, this article incorporates the analytical lenses of Kaupapa Māori Theory and Bronfenbrenner’s bio-ecological model. It concludes by outlining some priorities to consider for science education development based on the outcomes of our preliminary discussions.

Patterns of and influences on elementary school attendance in early Victorian industrial Monmouthshire 1839–1865

Issues associated with school absenteeism have attracted considerable attention and have long been one of the focal points of government strategies for school improvement. Pupil non-attendance is not a new phenomenon and featured prominently in Her Majesty’s Inspectors’ reports from 1839. This paper outlines the patterns of and influences on elementary education in early Victorian industrial Monmouthshire during the period 1839–1865. The twin problems of irregular attendance and early withdrawal of pupils are discussed together with the limitations and unreliability of contemporary statistics. An examination of the reasons for absence is then discussed together with the remedies proposed to alleviate the problem with particular reference to the contribution of the Prize Schemes. The paper illustrates the disadvantages of basing an educational system on voluntary endeavour and enlightened self-interest and highlights the paradox that, despite the introduction of mandatory attendance, the problem is still persistent and protracted and finding definitive solutions still remains elusive.     

Leveraging information and communication technologies (ICT) to enhance education equity,quality, and efficiency: case studies of Bangladesh and Nepal

ABSTRACT

Information and Communication Technologies (ICT) have had significant impacts on many sectors in today’s knowledge economy. In developing and emerging countries, ICT have enhanced equity, quality, and efficiency in the education sector. However, the adoption of ICT in the South Asian countries’ education sector has not been at scale and its impacts have been limited. There are several gaps and issues that are hindering the wider adoption of ICT and limiting its impacts in the education sector. Through the case studies of the adoption of ICT for education in Bangladesh and Nepal, this paper examines the gaps and issues to be addressed in order to better leverage ICT to enhance education equity, quality, and efficiency. This discussion is guided by the ICT in the education framework that has been developed by the authors, and could provide insights into the state of ICT in education and offer strategies to better leverage ICT for the education sector of other countries in South Asia and the region.
