Researching research: mathematics education in the Political     

Alexandre Pais  Paola Valero 《Educational Studies in Mathematics》2012,80(1-2):9-24

We discuss contemporary theories in mathematics education in order to do research on research. Our strategy consists of analysing discursively and ideologically recent key publications addressing the role of theory in mathematics education research. We examine how the field fabricates its object of research by deploying Foucault’s notion of bio-politics—mainly to address the object “learning”—and ?i?ek’s ideology critique—to address the object “mathematics”. These theories, which have already been used in the field to research teaching and learning, have a great potential to contribute to a reflexivity of research on its discourses and effects. Furthermore, they enable us to present a clear distinction between what has been called the sociopolitical turn in mathematics education research and what we call a positioning of mathematics education (research) practices in the Political.  相似文献   

The Relationship Between Running Economy and Biomechanical Variables in Distance Runners     

Marcus Peikriszwili Tartaruga  Jeanick Brisswalter  Leonardo Alexandre Peyré-Tartaruga  Aluísio Otávio Vargas Ávila  Cristine Lima Alberton  Marcelo Coertjens 《Research quarterly for exercise and sport》2013,84(3):367-375

In this study, we analyzed the relationship between running economy (RE) and biomechanical parameters in a group running at the same relative intensity and same absolute velocity. Sixteen homogeneous male long-distance runners performed a test to determine RE at 4.4 m.s^-1, corresponding to 11.1% below velocity at the ventilatory threshold. We found significant correlations between RE and biomechanical variables (vertical oscillation of the center of mass, stride frequency, stride length, balance time, relative stride length, range of elbow motion, internal knee, ankle angles at foot strike, and electromyographic activity of the semitendinosus and rectus femoris muscles). In conclusion, changes in running technique can influence RE and lead to improved running performance.  相似文献   

School Life and Adolescents' Self‐Esteem Trajectories     

Alexandre J. S. Morin  Christophe Maïano  Herbert W. Marsh  Benjamin Nagengast  Michel Janosz 《Child development》2013,84(6):1967-1988

This study investigates heterogeneity in adolescents' trajectories of global self‐esteem (GSE) and the relations between these trajectories and facets of the interpersonal, organizational, and instructional components of students' school life. Methodologically, this study illustrates the use of growth mixture analyses, and how to obtain proper student‐level effects when there are multiple schools, but not enough to support multilevel analyses. This study is based on a 4‐year, six‐measurement‐point, follow‐up of 1,008 adolescents (M_age = 12.6 years, SD = 0.6 at Time 1.) The results show four latent classes presenting elevated, moderate, increasing, and low trajectories defined based on GSE levels and fluctuations. The results show that GSE becomes trait‐like as it increases and that school life effects, moderated by gender, played an important role in predicting membership in these trajectories.  相似文献   

Private tutoring through the internet: globalization and offshoring   总被引：1，自引：0，他引：1  

Alexandre Ventura  Sunhwa Jang 《Asia Pacific Education Review》2010,11(1):59-68

The private tutoring industry has come forward as the third great sector of education. The common sense representation about private tutoring is changing. The growing search for supplementary educational support services and the technological innovation have created a new paradigm. This paper focuses on one of the most interesting faces of this new phenomenon: the rise of private tutoring through the internet. The very promising market is considered by some analysts as a true explosion on the offer and demand levels. Many families are feeling increasingly unable to provide their children the “extra help” they need to meet the requirements of further steps in the education system. So, for several reasons, they are outsourcing and even offshoring this so important and competitive task. The field is full of learning and market opportunities. This is the new globalized world of the less shadow and progressively growing private tutoring in the XXI century.  相似文献

Whither social theory?     

Alexandre Pais  Paola Valero 《Educational Studies in Mathematics》2014,87(2):241-248

What is the place of social theory in mathematics education research, and what is it for? This special issue of Educational Studies in Mathematics offers insights on what could be the role of some sociological theories in a field that has historically privileged learning theories coming from psychology and mathematics as the main theoretical frames informing research. Although during the last 10 years the term “socio-cultural” has become part of the accepted and widespread trends of mathematics education research when addressing learning, this issue gathers a collection of papers that depart from a “socio-cultural” approach to learning and rather deploy sociological theories in the analysis of mathematics education practices. In this commentary paper, we will point to what we see to be the contributions of these papers to the field. We will do so by highlighting issues that run through the six papers. We will try to synthetize what we think are the benchmarks of the social approach to mathematics education that they propose. We will also take a critical stance and indicate some possible extensions of the use of social theory that are not addressed in this special issue but nonetheless are worth being explored for a fuller understanding of the “social” in mathematics education.  相似文献   

An ideology critique of the use-value of mathematics   总被引：1，自引：0，他引：1  

Alexandre Pais 《Educational Studies in Mathematics》2013,84(1):15-34

The idea that mathematics is needed for our mundane everyday activities has raised the question of how people deal with mathematics outside the school walls. Much has been written in mathematics education research about the possibility of transferring knowledge from and into school. Whereas the majority of this literature commends the possibility of transfer, thus assuming both the desirability of transfer and the importance of school mathematics for the professional and mundane lives of individuals, I am interested in developing an ideology critique on the beliefs underpinning the research on this issue. It will be argued that the use-value attributed to school mathematics disavows its value as part of a political and economic structure, which requires school mathematics to perform other roles than the one related with utility. This critique will be illustrated through the exploration of a typical transfer situation between school and workplace.  相似文献

Electronic circuit implementation of the chaotic Rulkov neuron model     

Alexandre Wagemakers  Miguel A.F. Sanjuán 《Journal of The Franklin Institute》2013,350(10):2901-2910

Numerical integration is the most common and straightforward approach in computational neuroscience for the study of biological neuron models based on ordinary differential equations. For some purposes, numerical simulations are not enough due to the multiple bottlenecks in computer architectures. However, when electronic circuits are used to simulate in real time large arrays of coupled neurons, the simulations are much faster than the computer simulations. We present here an electronic implementation of a map-based neuron model, a chaotic Rulkov neuron model, that can be easily transferred on a large scale integration circuit and thus provide a framework for the simulation of large networks of neurons. The Rulkov model is a map-based neuron model that has a surprising abundance of features, such as periodic and chaotic spiking and bursting. The discrete time dynamics allows to tune the time scale of the circuit to the needs of the specific application. Since the circuit described here only uses 18 MOS transistors, it offers new perspectives for building large networks of neurons in a single device. This is very relevant for the analysis of large networks of coupled neurons in order to investigate its dynamics over the network and its synchronization properties.  相似文献   

Perceptions of the Bologna process: what do students’ choices reveal?     

Miguel Portela  Carla Sá  Fernando Alexandre  Ana Rute Cardoso 《Higher Education》2009,58(4):465-474

A major element in the creation of the European area of higher education is the adoption of a common structure of degrees, implying in several countries the reduction of the duration of the first degree to 3 years, which is a controversial change. Cardoso et al. (CESifo Econ Stud 54(2): 229–247, 2008) have analyzed student confidence in the curricula change, quantifying its impact on students’ first choices of academic programs. This paper goes two steps further. First, it concentrates on a variable that better translates total demand for an academic program, namely the total number of students who place the program among their six revealed preferences, instead of just the first option; and, second, an econometric model that better fits the data is estimated. Results confirm a positive impact of the Bologna process on the demand for programs, which varies with program size and across fields of study. Our results complement those in Cardoso et al. (2008), as they uncover that being a program leader, i.e. the only institution in the country that restructured a given program, was associated with higher demand by prospective students, which nevertheless stemmed from their “second best" options and not from their first choices.
