Teaching English-Spanish cognate-recognition strategies through the Américas Book Award-winners and honor picture books     

José A. Montelongo  Anita C. Hernández  Johanna Esquivel  Francisco Serrano-Wall  Adriana Goenaga de Zuazu 《Journal of Latinos & Education》2018,17(4):300-313

Cognates are words that are the same or nearly the same orthographically and semantically in English and Spanish. The majority of the more than 20,000 cognates are academic vocabulary words comprised of Latin and Greek roots and affixes. Several thousand cognates can be found in the picture books that have earned the Américas Book Award, which was established to honor quality multicultural books that portray Latino cultures in a positive light. The authors present lessons for teaching primary school Latino ELLs about cognates through the Américas Award picture books, as they educate their students about their rich Latino cultures.  相似文献   

Optimal Nash tuning rules for robust PID controllers     

Helem Sabina Sánchez  Antonio Visioli  Ramon Vilanova 《Journal of The Franklin Institute》2017,354(10):3945-3970

In this paper, we propose tuning rules for one degree-of-freedom proportional-integral-derivative controllers, by considering important aspects such as the trade-off in the performance in the servo and regulation operation modes and the control system robustness by constraining the maximum sensitivity peak. The different conflicting objectives are dealt with by using a multi-objective optimization algorithm to generate the trade-off optimal solutions. In this context, a simple tuning rule is determined by using the Nash solutions as a multi-criteria decision making technique. The Nash criteria is shown to provide convenient trade-off solutions for the controller tuning problem. Illustrative simulation examples show the effectiveness of the method.  相似文献   

Universities,knowledge and pedagogical configurations: Glimpsing the complex university     

Carolina Guzmán-Valenzuela 《Educational Philosophy and Theory》2018,50(1):5-17

This paper elaborates a typology of universities in which each university is characteristically associated with (i) diverse missions, (ii) different ways of producing knowledge and (iii) contrasting pedagogical configurations. Four university forms are identified, analysed and illustrated, namely the expert university, the non-elite university, the entrepreneurial university and the revolutionary university. It is suggested that the typology and the analysis of university forms offered here provide insight into the current positioning of universities in relation to the wider world and have potential in prompting new forms of university for the twenty-first century. The paper further advances another possible university for the future, namely the complex university. The complex university is part of and respectful of diverse ecosystems. It creates new frameworks to understand the world and, in that way, supports social transformations.  相似文献   

A school-based motivational intervention to promote physical activity from a self-determination theory perspective     

David González-Cutre  Ana C. Sierra  Vicente J. Beltrán-Carrillo  Manuel Peláez-Pérez  Eduardo Cervelló 《The Journal of educational research》2018,111(3):320-330

The authors analyzed the effects of a multidimensional intervention to promote physical activity (PA) in school, based on self-determination theory. The study involved 88 students, between 14 and 17 years old, who were divided into a control group (n = 59) and an experimental group (n = 29). In the experimental group, a 6-month intervention was conducted, applying a teaching unit of fitness and health in physical education (PE) classes, an extracurricular program of healthy PA, and meetings with families. Questionnaires were administered to measure different motivational variables and PA levels at four time points. Significant differences were found in favor of the experimental group in parental and peer autonomy support; integrated regulation in PE; autonomy, intrinsic, and identified regulation in leisure-time PA; moderate, hard, and very hard PA; and physical self-worth. Motivational effects were maintained over time but the effects on PA levels disappeared at 6 months.  相似文献   

How Should Energy Be Defined Throughout Schooling?     

Manuel Bächtold 《Research in Science Education》2018,48(2):345-367

The question of how to teach energy has been renewed by recent studies focusing on the learning and teaching progressions for this concept. In this context, one question has been, for the most part, overlooked: how should energy be defined throughout schooling? This paper addresses this question in three steps. We first identify and discuss two main approaches in physics concerning the definition of energy, one claiming there is no satisfactory definition and taking conservation as a fundamental property, and the other based on Rankine’s definition of energy as the capacity of a system to produce changes. We then present a study concerning how energy is actually defined throughout schooling in the case of France by analyzing national programs, physics textbooks, and the answers of teachers to a questionnaire. This study brings to light a consistency problem in the way energy is defined across school years: in primary school, an adapted version of Rankine’s definition is introduced and conservation is ignored; in high school, conservation is introduced and Rankine’s definition is ignored. Finally, we address this consistency problem by discussing possible teaching progressions. We argue in favor of the use of Rankine’s definition throughout schooling: at primary school, it is a possible substitute to students’ erroneous conceptions; at secondary school, it might help students become aware of the unifying role of energy and thereby overcome the compartmentalization problem.  相似文献   

Towards the university entrepreneurial mission: Portuguese academics’ self-perspective of their role in knowledge transfer     

Elisabete Sá  Diana Dias 《Journal of Further & Higher Education》2018,42(6):784-796

The role of the university in society and the economy is evolving. Universities produce knowledge that promotes technological developments, which are, in turn, critical to economic growth and competitiveness in the global economy. Therefore, it is increasingly expected that universities become more entrepreneurial and assume this third mission in order to promote innovation and development through the provision of technologies and business ventures. Drawing on data collected for The Changing Academic Profession Project – a comparative survey of the academic profession carried out in 19 countries from all over the world – this article explores Portuguese academic entrepreneurship engagement based on the involvement in the process of technology transfer as an activity performed in the context of research activities. It thus aims to contribute to knowledge about academics’ engagement in entrepreneurial activity. Results from this study suggest that Portuguese academics are fairly involved in entrepreneurial activities and that there is an overall positive attitude towards application of research to real problems. Furthermore, it was possible to see that academics involved in processes of technology transfer are not only focused on activities such as research but also service to the outside community. However, when comparing academics involved and not involved in entrepreneurial activities, several significant differences are found in their attitudes, perceptions and behaviours.  相似文献

Children's rights and their subjective well-being from a multinational perspective     

Ferran Casas  Mònica González-Carrasco  Xevi Luna 《European Journal of Education》2018,53(3):336-350

This article explores the relationship between children's knowledge and perceptions about their rights and subjective well-being (SWB) in a sample of 8-, 10- and 12-year-olds in 18 countries, taking account of gender differences. Children's knowledge and perceptions about their rights were analysed considering whether they reported that they knew their rights, whether they had heard about the UN Convention on the Rights of the Child (CRC) and whether they thought that, in their country, adults respected their rights. To explore SWB, a modified version of the Student's Life Satisfaction Scale, adapted by the Children's Worlds project, was used. Children reporting that they knew their rights, knew about the CRC, or thought that in their country adults respected their rights demonstrated significantly higher SWB scores than those reporting otherwise in the 18 countries. The effects of perceiving that adults in general respected children's rights in their own country on SWB were much more important than the knowledge of children's rights or the knowledge of the CRC. Results provide useful indications on how to promote children's well-being in public policies, including in education, through the promotion of their rights.  相似文献   

Effects of a psychomotor intervention programme in preadolescents with Down syndrome / Efectos de un programa de intervención psicomotriz en preadolescentes con síndrome de Down     

Verónica Martínez  Aránzazu Antón 《Infancia y Aprendizaje》2018,41(1):165-199

Movement is key to human physical and mental maturation, hence the importance of non-delayed psychomotor development. Psychomotor development occurs much later in children with Down Syndrome (DS) as compared with typically developing children. The objective of this research is to assess the effectiveness of an intervention programme aimed at the psychomotor development of preadolescents with DS (Experimental Group n = 5, Control Group n = 5), focusing on body schema and spatio-temporal structure. Results show a significant increase in body awareness as well as in concepts of space and quantity. Nevertheless, it is necessary to consolidate these motor abilities in a personalized and more prolonged way in order to minimize psychomotor developmental delays.  相似文献   

Exploring fourth graders’ sourcing skills / Un análisis de la capacidad de escrutinio sobre las fuentes de información de los estudiantes de cuarto grado     

Johanna Paul  Raquel Cerdán  Jean-François Rouet  Marc Stadtler 《Infancia y Aprendizaje》2018,41(3):536-580

Acquiring information from the Web creates new educational demands even in elementary school. Children need to scrutinize source information (‘sourcing’) to choose trustworthy information. So far, few studies have documented young readers’ abilities to identify and evaluate source information. With two studies, we seek to gather more evidence on elementary students’ sourcing skills and use. In study 1, we investigate to what extent fourth graders can identify source information and evaluate informants’ expertise and intentions in simplistic, age-appropriate reading tasks. In study 2, we explore whether fourth graders spontaneously apply their sourcing skills when reading simplified multiple documents. Results suggest that fourth graders can successfully identify source information and evaluate informants’ expertise and intentions in simple and direct tasks but fail to apply this ability to more complex and implicit tasks. Implications for information literacy education are discussed.  相似文献
