Parental preferences in the choice for a specialty school     

Lydia M. Prieto  Jonathan Aguero-Valverde  Gustavo Zarrate-Cardenas  Martin Van Maarseveen 《Journal of School Choice》2019,13(2):198-227

Choosing a specialty school involves huge challenges for families. This research aims to understand the behavioral process that leads families to choose among various specialty school programs. Discrete choice models, based on revealed preferences data from middle school applications in a large school district in Florida, are estimated using both, the top and all-ranked alternatives. This study returns insights into geographic settings, theme specialties and socioeconomic characteristics of applicants, schools and their relationships. Distance from home, the school’s academic quality, the school’s theme specialty, and the high percentage of applicant’s own race are found to be the strongest factors related to the decision to apply.  相似文献   

Speaking Q’anjobal,Spanish, and English: a world where other worlds are possible     

Beatriz Eugenia Guerrero-Arias 《Diaspora, Indigenous, and Minority Education》2019,13(3):133-145

Currently, there is a call for more humane ways in humanities, for transitions to a world where other worlds are possible. This qualitative case study analyzes an emergent translingual boy’s participation in diverse spatial repertoires to address issues of learning and community belonging. José is a 4-year-old preschool Guatemalan-ancestry boy, who speaks Q’anjob’al, Spanish, and English. He was placed in an English classroom with daily 30-min Spanish and English pullout. José participated in the pullout to a desirable extent but was marginalized in the English classroom. At home, José had varied opportunities for participating in diverse spatial repertoires. I discuss how home and school have different conceptions of learning and community belonging, and how the home setting with pluriversed spatial repertoires sheds light on a pedagogical practice aimed at transitioning towards a world where other worlds are possible.  相似文献

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   

An Enquiry into the Influence of Mathematics on Students’ Choice of STEM Careers     

Elena Prieto  Nicola Dugar 《International Journal of Science and Mathematics Education》2017,15(8):1501-1520

Australia currently faces a skill shortage in Science, Technology, Engineering and Mathematics (STEM) professions unlikely to improve if the current trend of low enrolments in high-level mathematics in secondary school continues. Many factors seem to contribute to this trend, and amongst them, research recognises student attitudes towards mathematics and careers in STEM. Research also shows that teachers and classroom practices are key agents to change these attitudes. This paper examines teachers’ perceptions of students’ attitudes towards mathematics and careers in STEM, as well as classroom practices emanating from those perceptions. Combining data from two studies, a large-scale survey and an intervention, we argue three main points: (1) student attitudes and teachers’ perceptions of those attitudes quite clearly differ, (2) targeted interventions showing links between mathematics and careers in STEM can have an influence on students’ perceptions of STEM careers and (3) an implementation of classroom ability grouping based on standardised test scores can be disadvantageous to students who have a natural inclination towards STEM and positive attitudes towards mathematics.  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
