Using Multi-Modal Representations to Improve Learning in Junior Secondary Science     

Bruce Waldrip  Vaughan Prain  Jim Carolan 《Research in Science Education》2010,40(1):65-80

There is growing research interest in both the challenges and opportunities learners face in trying to represent scientific understanding, processes and reasoning. These challenges are increasingly well understood by researchers, including integrating verbal, visual and mathematical modes in science discourse, and making strong conceptual links between classroom experiences and diverse 3D and 2D representations. However, a matching enhanced pedagogy of representation-rich learning opportunities, including their theoretical justification, is much less clearly established. Our paper reports on part of a three-year project to identify practical and theoretical issues entailed in developing a pedagogical framework to guide teacher understanding and practices to maximize representational opportunities for learners to develop conceptual understandings in science.  相似文献

Assessing Student Achievement in Large-Scale Educational Programs Using Hierarchical Propensity Scores     

Angela L. Vaughan  Trent L. Lalonde  Michael A. Jenkins-Guarnieri 《Research in higher education》2014,55(6):564-580

Many researchers assessing the efficacy of educational programs face challenges due to issues with non-randomization and the likelihood of dependence between nested subjects. The purpose of the study was to demonstrate a rigorous research methodology using a hierarchical propensity score matching method that can be utilized in contexts where randomization is not feasible and dependence between subjects is a concern. Although propensity score matching is not new in helping to create quasi-experimental models, many studies limit propensity score matching to student-level variables. To address this limitation in educational research, this study extends propensity score matching to the next level so that hierarchical modeling techniques can be used to help minimize error due to the likelihood of dependence between nested students. A large-scale educational program that targets first-semester freshmen was used to illustrate the utility and value of the methodology. This type of program is typical in higher education where student self-selection creates difficulty in assessing its true effects on student achievement; however, by using a rigorous methodology, administrators can have higher confidence when making programmatic and budgetary decisions.  相似文献   

Web traffic and organization performance measures: Relationships and data sources examined     

Liwen Vaughan  Rongbin Yang 《Journal of Informetrics》2013,7(3):699-711

Unlike Web hyperlink data, Web traffic data have not yet been the focus of considerable study in Webometrics research. The relationships between Web traffic data and academic/business performance measures have not been as firmly established as the relationships between Web hyperlink data and such performance measures. Although various traffic data sources exist, few studies have examined and compared their relative merits. We carried out a study that aimed to address this lack. We selected groups of universities and businesses from the U.S. and China and collected their Web traffic data from three sources: Alexa Internet, Google Trends for Websites, and Compete. We found significant correlations between Web traffic data and organizational performance measures, specifically academic quality for universities and financial variables for businesses. We also examined the characteristics of the three data sources and compared their usefulness. We found that Alexa Internet outperformed the others.  相似文献   

Personalised learning: lessons to be learnt     

Vaughan Prain  Peter Cox  Craig Deed  Jeffrey Dorman  Debra Edwards  Cathleen Farrelly  Mary Keeffe  Valerie Lovejoy  Lucy Mow  Peter Sellings  Bruce Waldrip  Zali Yager 《British Educational Research Journal》2013,39(4):654-676

Personalised learning is now broadly endorsed as a key strategy to improve student curricular engagement and academic attainment, but there is also strong critique of this construct. We review claims made for this approach, as well as concerns about its conceptual coherence and effects on different learner cohorts. Drawing on literature around differentiation of the curriculum, self‐regulated learning, and ‘relational agency’ we propose a framework for conceptualising and enacting this construct. We then report on an attempt to introduce personalised learning as one strategy, among several, to improve student academic performance and wellbeing in four low SES regional secondary schools in Australia. We report on a survey of 2407 students’ perceptions of the extent to which their school provided a personalised learning environment, and a case study of a programme within one school that aimed to apply a personalised approach to the mathematics curriculum. We found that while there were ongoing challenges in this approach, there was also evidence of success in the mathematics case.  相似文献   

The importance of capabilities in the sustainability of information and communications technology programs: the case of remote Indigenous Australian communities     

Donna Vaughan 《Ethics and Information Technology》2011,13(2):131-150

The use of the capability approach as an evaluative tool for Information and Communication Technology (ICT) policy and programs in developing countries, in particular at a grass-roots community level, is an emerging field of application. However, one of the difficulties with ICT for development (ICT4D) evaluations is in linking what is often no more than a resource, for example basic access, to actual outcomes, or means to end. This article argues that the capability approach provides a framework for evaluating the strength of this linkage and that the latter is a key determinant of whether or not communities sustain ICT4D programs beyond the initial start-up phase. The argument is made by describing an evaluative application of the capabilities approach to community ICT4D programs using two Indigenous community case studies conducted in Cape York, in the far north-east of Australia. Key to the evaluative approach is the identification of community defined, context specific concepts of well-being and constitutive valued functionings and the derivation from this of required capabilities. This move away from normative definitions of capabilities or capability types to a definition that reflects the Indigenous culture, history, circumstances, and well-being aspirations of each community is intended to give a voice to the people and at the same time provide a deeper informational base—through narrative—for policy and program design than has previously been available. The article concludes that by operationalising the capability approach in a context and purpose specific way, policy and program design can be improved so as to include more communities on the margin and thereby achieve more socially inclusive ICT based development. A process is also outlined for using the evaluative application of the capability approach for community ICT4D within a policy feedback loop.  相似文献   

A battery of strength tests for evidence-based classification in Para swimming

This study examined the validity of isometric strength tests for evidence-based classification in Para swimming. Thirty non-disabled participants and forty-two Para swimmers with physical impairment completed an isometric strength test battery designed to explain activity limitation in the freestyle discipline. Measures pertaining to dominant and non-dominant limb strength and symmetry were derived from four strength tests that were found to be reliable in a cohort of non-disabled participants (ICC = 0.85–0.97; CV = 6.4–9.1%). Para swimmers had lower scores in strength tests compared with non-disabled participants (d = 0.14–1.00) and the strength test battery successfully classified 95% of Para swimmers with physical impairment using random forest algorithm. Most of the strength measures had low to moderate correlations (r = 0.32 to 0.53; p ≤ 0.05) with maximal freestyle swim speed in Para swimmers. Although, fewer correlations were found when Para swimmers with hypertonia or impaired muscle power were analysed independently, highlighting the impairment-specific nature of activity limitation in Para swimming. Collectively, the strength test battery has utility in Para swimming classification to infer loss of strength in Para swimmers, guide minimum eligibility criteria, and to define the impact that strength impairment has on Para swimming performance.  相似文献
