Developing an Initial Learning Progression for the Use of Evidence in Decision-Making Contexts     

Beatriz Bravo-Torija  María-Pilar Jiménez-Aleixandre 《International Journal of Science and Mathematics Education》2018,16(4):619-638

This paper outlines an initial learning progression for the use of evidence to support scientific arguments in the context of decision-making. Use of evidence is a central feature of knowledge evaluation and, therefore, of argumentation. The proposal is based on the literature on argumentation and use of evidence in decision-making contexts. The objective is to develop a construct map describing a trajectory of evidence use in a decision-making context. The levels in the initial learning progression are characterised by students’ performance in practice. The framework is applied to a multiple-case study in 10th grade (66 students), structured around a marine resource management task. Data included audio and video recordings, as well as students’ written artefacts. Five levels of complexity in student performance are described; on the lowest level, students are able to identify and extract information in response to a problem and recognise general features in a set of data; on the uppermost level, they are able to articulate arguments by synthesising evidence from multiple sources and evaluate options based on evidence and scientific content. The framework also shows potential for recognising students’ difficulties in identifying and integrating data and evidence in their justifications and in drawing from domain knowledge to interpret evidence. Implications for educational practice are discussed.  相似文献

Scaramouche Goes to Preschool: The Complex Matrix of Young Children’s Everyday Music     

Beatriz Ilari 《Early Childhood Education Journal》2018,46(1):1-9

This article examines everyday musical practices and their connections to young children’s learning and development, in and through music. It begins with a discussion of music learning in early childhood as a form of participation and levels of intention in learning. Next, conceptions of child that have dominated early childhood music education discourses are discussed, along with other factors that are known to influence children’s musical lives, such as spatiality, repertoires and the politics of participation. Three illustrative vignettes that stem from the author’s experience as an early childhood music educator and researcher are presented throughout the text. Implications for early childhood education are outlined at the end.  相似文献   

Effect of wetted surface area on friction,pressure, wave and total drag of a kayak     

Beatriz B. Gomes  Leandro Machado  Nuno V. Ramos  Filipe A. V. Conceição  Ross H. Sanders  Mário A. P. Vaz 《Sports biomechanics / International Society of Biomechanics in Sports》2018,17(4):453-461

Using theoretical principles, the components of drag (friction D _F, pressure D _PR and wave D _W) of a single-seat kayak were analysed. The purpose was to examine the effect of changes in wetted surface area due to changes in kayaker’s weight and the relative contribution of D _F, D _PR and D _W to the total passive drag as function of velocity. The total passive drag values were based on experimental data collected in a single-seat kayak. Three different kayaker simulated weights were tested – 65, 75 and 85 kg. D _F was the drag component that contributed the greatest percentage (between 60 and 68% at 5.56 m/s the top velocity tested) to the total passive drag for all the velocities tested and simulated weights. D _W was the most affected by the increase in kayaker’s simulated weight, mainly when comparing 65/75 to 85 kg. Results support the importance of a kayak design selection that minimises the kayak’s drag for the individual weight of the kayaker. Also, the results suggest that the path for better hydrodynamic kayak performance should seek changes that can reduce D _F, D _PR and D _W with D _F offering the most potential to reduce passive drag.  相似文献   

Cutting without Cursing: A Successful Cancellation Project     

Beatriz Betancourt Hardy  Martha C. Zimmerman  Laura A. Hanscom 《期刊图书馆员》2016,71(2):112-120

The Salisbury University Libraries embarked on a serials and database cancellation project in the 2014–2015 academic year, eventually cutting nearly 20% of journals without causing any faculty protests. Picking up ideas from numerous other libraries, the three-person project task force developed a three-stage process: 1) preparation—gathering data and laying the groundwork for getting feedback; 2) getting feedback from liaisons, faculty, and departments; and 3) making decisions about what to cut and sharing the results. This article details the steps taken and key recommendations for other libraries undertaking similar projects.  相似文献   

Objectively measured sedentary time and academic achievement in schoolchildren     

Luís Lopes  Rute Santos  Jorge Mota  Beatriz Pereira  Vítor Lopes 《Journal of sports sciences》2017,35(5):463-469

This study aimed to evaluate the relationship between objectively measured total sedentary time and academic achievement (AA) in Portuguese children. The sample comprised of 213 children (51.6% girls) aged 9.46 ± 0.43 years, from the north of Portugal. Sedentary time was measured with accelerometry, and AA was assessed using the Portuguese Language and Mathematics National Exams results. Multilevel linear regression models were fitted to assess regression coefficients predicting AA. The results showed that objectively measured total sedentary time was not associated with AA, after adjusting for potential confounders.  相似文献   

Valuing museums as economic engines: Willingness to pay or discounting of cash-flows?     

Beatriz Plaza 《Journal of Cultural Heritage》2010,11(2):155-162

GLobal Art MUseums as Economic Re-activators (GLAMUR) infrastructures are characterized by global media visibility and sheer presence in the communications environment; outstanding architecture by a superstar architect; big blockbuster exhibitions and a large number of visitors; being magnets for tourists; requiring large capital costs (initial construction costs plus ongoing investments) and large operating budgets; expensive advertising and commercialisation strategies; a huge operative risk; and a hope for substantial impact on the local economy. The economic value of cultural assets is defined as the extent to which they generate benefits for society. The aim of this article is to shed light on the valuation of GLAMUR infrastructures and why, and then to valuate the Guggenheim Museum Bilbao (GMB). In fact, the author of this paper argues that economic valuation through an estimate of the Willingness to Pay (WTP) (e.g. contingent valuation), is clearly an insufficient method for valuating a GLAMUR. One possible accurate method could be to calculate the Discounting of Cash-flows (DCF), followed by the discounting of the WTP estimates.  相似文献
