Understanding of graphs in social science undergraduate students: selection and interpretation of graphs     

Mª del Puy Pérez-Echeverría  Cristina Marín 《Irish Educational Studies》2018,37(1):89-111

How do university students understand the graphs that they read in their textbooks? How does their knowledge regarding the content and their statistical training influence this understanding? Does the kind of task demand also influence this understanding? To answer these questions, we asked a group of psychology students and a group of economics students to choose the most suitable graph for presenting the results of different psychological research studies (reports) (selection task) or to explain in words the results of the same reports shown by means of their graphic representations only (interpretation task). The results showed there were very few differences between groups. Most of the students were able to relate textual information to the adequate graph, but also revealed significant shortcomings and mistakes in their understanding of important syntactic aspects of graphs. They also interpreted the graphs correctly but their interpretation had different levels of complexity, which were not always optimal. We also identified significant differences regarding the difficulty of the reports and the kinds of misinterpretations of graphs. The two tasks thus revealed different pictures of students’ skills in reading and interpreting graphs and, consequently, how the characteristics of task demands influence their performance.  相似文献

Can Early Childhood Curriculum Enhance Social-Emotional Competence in Low-Income Children? A Meta-Analysis of the Educational Effects     

Weipeng Yang  Jesus Alfonso D. Datu  Xunyi Lin  Michelle Marie Lau  Hui Li 《Early education and development》2019,30(1):36-59

Research Findings: This meta-analysis examined 29 (quasi-)experimental studies that involved low-income children ages 3 to 5 who might be subject to risks of academic failure and other negative outcomes. Compared to the controls, children who learned with social-emotional learning (SEL) curricula demonstrated significantly improved social-emotional competence, with an effect size or standardized mean difference of 0.241 (95% confidence interval [0.194, 0.287]). However, the use of other curricula that lacked an intensive focus on SEL yielded nonsignificant effects on the social-emotional competence of low-income children. Type of curriculum, fidelity of curriculum implementation, and duration of intervention were found to moderate the educational effects. Practice or Policy: The findings of this meta-analysis contribute to the growing body of empirical evidence on the positive effects of early SEL curricula and explain how curricula can produce social-emotional benefits for low-income children in their early years.  相似文献   

The immediate-shock deficit and postshock analgesia: Implications for the relationship between the analgesic CR and UR     

Michael S. Fanselow  Jesus Landeira-Fernandez  Joseph P. DeCola  Jeansok J. Kim 《Learning & behavior》1994,22(1):72-76

Rats received a 3-sec, 1-mA footshock either immediately or 3 min after placement in a chamber. Postshock pain sensitivity was assessed with the formalin test. The animals that received the 3-min delay between placement and shock showed an analgesic response compared with noshock controls. The immediate-shock animals did not. Thus the immediate-shock deficit, previously reported for freezing and defecation, also occurs for analgesia. This suggests that shock levels sufficient to condition analgesia are not necessarily sufficient to produce analgesia as an unconditional response. As with freezing, there is a dissociation between conditional and unconditional responses in the fear-conditioning system. Increasing immediate-shock levels to 6 sec, 2 mA produced a transient unconditional analgesia. For analgesia, a conditional response is more readily produced than an unconditional response.  相似文献   

From savages to capitalists: progressive images of education in the UK and the USA (1920–1939)     

Sjaak Braster  María del Mar del Pozo Andrés 《History of education》2020,49(4):571-595

ABSTRACT

One strand of historical research in education that sails on the waves of the visual turn in history concerns the progressive image of education. A major reference point is an article written in 2007 by Burke and Grosvenor, who, on the basis of the photographic archives of two progressive schools in England, constructed a visual typology of progressive education. After a content analysis of 944 images published in the educational journal The New Era and 1827 images in Progressive Education in the period 1920–1939, it is concluded that this typology is partly adequate for describing a common image of new education in the UK and progressive education in the USA. But it should be extended with two more elements: (a) urban discovery and nature exploration, and (b) cultural-historical representations and recapitulation. In the latter children are first portrayed as ‘primitive savages’ who later become little bankers and shopkeepers in a capitalist economy.  相似文献   

The mattress makers: emotions and value proposal in Atlético de Madrid     

Jesus Rodriguez-Pomeda  Fernando Casani  Maria del Mar Alonso-Almeida 《Soccer & Society》2016,17(1):1-17

Atlético de Madrid (ATM) Football Club has a single-hearted fan base regardless of the sport results, unlike megaclub’s fandoms (like Real Madrid, from the same city) that demand a steady stream of sporting triumphs. Literature is sparse about how second line clubs that must compete with megaclubs from the same city for a fan base develop a sustainable value proposal based on their fans’ emotions. We analyse the content of interviews with followers, TV-ads and financial statements to deal with ATM’s emotional base comprised of eleven emotions. Emotions like pride secure a fandom base loyal to ATM even in the absence of wins. Findings suggest that ATM’s value proposal (based on fandom satisfaction) focuses on a niche of fierce modern-style supporters with emotions attuned to the club’s performance.  相似文献   

Public education and student movements: the Chilean rebellion under a neoliberal experiment     

Jorge Inzunza  Jenny Assael  Rodrigo Cornejo  Jesus Redondo 《British Journal of Sociology of Education》2019,40(4):490-506

Abstract

Chile is recognized in the educational policy field as one of the first laboratories of neoliberal initiatives. These policies, initiated under the dictatorship of Augusto Pinochet, did not change with the new democratic governments after 1990. This characteristic led international organizations to promote the Chilean policies in different contexts in Latin America and beyond. In 2006, a high school student movement occupied public and private schools, demystifying the outcomes of these policies. A new wave of demonstrations took place in 2011, with a college student leadership that paralyzed a significant amount of universities and schools throughout the country. After both waves of mobilizations, the political system opened the process of policy-making that considered the demands of social movements. In this article, we explore the dynamics between educational policies and social student movements in Chile, and the possibilities of change in favor of public education.  相似文献   

Gender discourse about an ethic of care: nursery schoolteachers' perspectives     

Ma del Carmen Rodríguez  J. Vicente Peña  Carmen Ma Fernández  Ma Paulina Viñuela 《Gender and education》2006,18(2):183-197

In this paper we will show some of the results of research which took place in the Principality of Asturias (Spain). Its purpose was finding out the gender discourses used by nursery teachers. Although we will not provide an exhaustive list of all the conclusions reached so far, we will put forward one of the aspects which has been developed throughout the investigation; that is, we will discuss some of our observations and hypotheses on the differences observed by the teachers in boys and girls' caring and supporting behaviours. In order to do so, we focus on the type of discourse related to the ethic of care. We consider it a tool which allows teachers to build a type of narrative in which boys and girls are presented as opposites, relational and different from one another.  相似文献   

V + H: Hybrid architecture for DSS and OLTP     

María del Pilar Angeles  Victor González Castro 《International Journal of Information Management》2013,33(6):940-947

Previous research has been done to identify the best pragmatic approach that DBMSs must follow to manage different workloads. Some approaches have followed the “One size fits all” approach, trying to incorporate all features in a row-oriented DBMS (also called horizontal) to manage both OLTP and DSS workloads. Additionally, there have been specialized DBMS, following a columnar approach (also called vertical), that focuses on the growing demand to efficiently manage DSS workloads. This paper proposes a combination of both vertical and horizontal DBMS to best manage OLTP and DSS workloads. We have used mature, commercially available products from a single vendor and developed a custom middleware Decision Query Module that identifies the best option for most efficient execution of a query. This V + H architecture also offers the functionality of a mirrored DB without paying twice for storage.  相似文献
