The Anthropology of Meaning     

Luis Radford 《Educational Studies in Mathematics》2006,61(1-2):39-65

Meaning is one of the recent terms which have gained great currency in mathematics education. It is generally used as a correlate of individuals' intentions and considered a central element in contemporary accounts of knowledge formation. One important question that arises in this context is the following: if, in one way or another, knowledge rests on the intrinsically subjective intentions and deeds of the individual, how can the objectivity of conceptual mathematical entities be guaranteed? In the first part of this paper, both Peirce's and Husserl's theories of meaning are discussed in light of the aforementioned question. I examine their attempts to reconcile the subjective dimension of knowing with the alleged transcendental nature of mathematical objects. I argue that transcendentalism, either in Peirce's or Husserl's theory of meaning, leads to an irresolvable tension between subject and object. In the final part of the article, I sketch a notion of meaning and conceptual objects based on a semiotic-cultural approach to cognition and knowledge which gives up transcendentalism and instead conveys the notion of contextual objectivity.  相似文献   

The Hispanic Experience in Physical Education Teacher Education Programs: A Qualitative Study     

Luis Columna  Samuel R. Hodge  Amaury Samalot-Rivera  Alexander N. Vigo-Valentín  Carlos M. Cervantes 《Quest (Human Kinetics)》2018,70(2):256-274

The purpose of this study was to describe the experiences of Hispanic faculty involved in physical education teacher education programs at predominantly White colleges and universities in the United States. The study was positioned in the theoretical framework of organizational socialization. Participants were Hispanic (n = 6) faculty from various kinesiology-based programs in tenure-track positions at institutions of higher education in the United States. Data were collected via semi-structured interviews and transcribed, triangulated, and analyzed with constant comparative procedures. We uncovered the following themes: (a) underrepresented, (b) socialized, and (c) cultured and determined. The study’s findings magnify the need for faculty and administrators to heighten their awareness and implement strategies to improve the organizational socialization of Hispanic faculty, particularly at predominantly White doctoral-granting colleges and universities. This means, for instance, identifying strategies to recruit, prepare, retain, and mentor Hispanic faculty at such institutions.  相似文献

Mid-life career changing to teaching profession: a study of secondary school teachers in a rural community     

Luis Miguel Dos Santos 《师资教育杂志》2019,45(2):225-227

There are many research projects focused on pre-service teachers’ professional development programmes but only a few focus on mid-life career-changing teachers’ career decision. This paper worked with data collected from semi-structured interviews with 11 mid-life career-changing secondary school teachers. The aim was to understand the career decisions of these participants and how they made sense of their new profession during their mature adulthood in Indiana, USA. 11 mid-life career-changing secondary school teachers referred to ‘changing the next generation with industry experience’, ‘rich life experience’, ‘life-long learning’, ‘knowledge transferring’, and ‘make a difference’ to describe their current occupation as career changing secondary school teachers. The findings also outline how to reform the curriculum and instruction of the pre-service teachers’ professional development programmes.  相似文献   

Analysis of the Meanings of the Antiderivative Used by Students of the First Engineering Courses     

Luis R. Pino-Fan  Vicenç Font  Wilson Gordillo  Víctor Larios  Adriana Breda 《International Journal of Science and Mathematics Education》2018,16(6):1091-1113

In this article, we present the results of the administration of a questionnaire designed to evaluate the understanding that civil engineering students have of the antiderivative. The questionnaire was simultaneously administered to samples of Mexican and Colombian students. For the analysis of the answers, we used some theoretical and methodological notions provided by the theoretical model known as Onto-Semiotic Approach (OSA) to mathematical cognition and instruction. The results revealed the meanings of the antiderivative that are more predominantly used by civil engineering students. Also, the comparison between the mathematical activity of Mexican and Colombian students provides information that allows concluding that the meanings mobilized could be shared among their communities and are not particular of their classroom or university.  相似文献   

The association between homework and primary school children's academic achievement. International evidence from PIRLS and TIMSS     

John Jerrim  Luis Alejandro Lopez-Agudo  Oscar D. Marcenaro-Gutierrez 《European Journal of Education》2020,55(2):248-260

The association between time devoted to homework and children's academic achievement has long been an issue of great debate. A small number of mainly correlational studies have been conducted into this issue in a primary school setting, but have produced somewhat mixed results. In this paper we contribute to this literature by investigating the relationship between time spent upon homework and children's outcomes across 24 countries. By using a student fixed-effects approach, capturing differences in homework time amongst the same student across different school subjects, we argue that our results are likely to be subject to less confounding than much of the existing literature. We find little evidence that the amount of homework time primary school children are assigned is related to their academic achievement. This holds true across a large number of countries, survives various robustness tests and does not vary by gender or socio-economic status. We interpret this finding as suggesting that the homework assigned to primary school pupils may not be adequate to produce a positive association, and needs be improved if this time-consuming activity is ever going to bring benefits for children's academic achievement.  相似文献   

Extra-curricular participation in sports and socio-demographic factors in Spanish adolescents: the AVENA study     

Gracia-Marco L  Tomas C  Vicente-Rodriguez G  Jimenez-Pavon D  Rey-Lopez JP  Ortega FB  Lanza-Saiz R  Moreno LA 《Journal of sports sciences》2010,28(13):1383-1389

The aims of this study were to identify differences between the sexes in extra-curricular participation in sports and to determine its association with body fat and socio-demographic factors in Spanish adolescents. A total of 2165 adolescents (1124 males and 1041 females) aged 13.0-18.5 years from the AVENA Study participated. Participants filled in an ad hoc questionnaire for extra-curricular participation in sports, which was the dependent variable. Independent variables were: age, percent body fat, and father's and mother's educational level and occupation. Chi-square tests and logistic regression were applied. Bivariate analysis showed for male adolescents that age and father's occupation were related to extra-curricular participation in sports. In addition, body fat and mother's education and occupation (all P?相似文献   

Relationship quality,community promotion and brand loyalty in virtual communities: Evidence from free software communities     

Luis V. Casaló  Carlos Flavián  Miguel Guinalíu 《International Journal of Information Management》2010

The Internet has favored the growth of collaborative platforms where marketers and consumers interact to develop more engaging products and services. These platforms are usually centered in a specific brand/product and their members are linked by a shared admiration to that brand. This paper analyzes one of the most powerful online collaborative platforms, the free software (FS) case, which involves a lot of virtual communities developed around products such as Linux or Android, the new Google's mobile operating system. Our purpose is to determine some of the main antecedents and consequences of the consumer involvement in this type of communities. Results have shown that satisfaction with a virtual community may increase the level of consumer participation in that community. At the same time, a greater identification with the virtual community may increase indirectly the consumer participation thanks to the enhancement of his/her satisfaction with the community. We have also found positive and significant effects of consumer identification and participation on the level of community promotion. Finally, positive and significant effects of consumer participation and satisfaction with the community on loyalty to the FS were also found. These findings allow us to conclude some interesting managerial implications.  相似文献
