Las matemáticas en primaria y secundaria en la década de los 90

El acelerado cambio del papel de las matemáticas en el mundo en general o en cada cultura en particular, supone una serie de desafíos y cambios correlativos en la enseñanza de las matemáticas. En este ya clásico informe, convertido en libro tras su discusión en un seminario internacional, se pasa revista a ambos procesos y se sacan consecuencias concretas para la educación y los educadores sobre el lugar y el modo de abordar las matemáticas en el cunículum escolar.     

Black Obsession: The All Blacks’ Quest for World Cup Success

This paper explores the growth and development of the ‘art of swimming’ amongst Victorian female professional natationists when the common belief was that ‘ladies’ were not physiologically or emotionally equipped to withstand the rigours of physical exertion. The question is posed as to whether ornamental swimming was a ‘respectable’ form of entertainment for females to undertake or was it just another manifestation of the passion for freak-shows much loved by all social classes in late-Victorian England. Media coverage of this popular form of entertainment often described its female exponents as ‘nymphs’ and ‘naiads’, terms taken from Greek mythology in order to legitimise an activity that had strong sexual overtones. In so doing, the consumption of recreational activities, as opposed to sport, by females provided a course of less resistance from the sporting proselytisers throughout the period, 1870-c1910. Thus, the female pioneers of natation were able to promote their various ornamental swimming activities through their efforts in a variety of aquatic venues throughout the country. Their popularity resulted in a whole phalanx of nymphs and naiads being encouraged to demonstrate their mystical feats for the gratification of predominantly male-dominated audiences. But more significantly, they served to promote swimming amongst the female population for their own edification as a respectable recreational pursuit.     

Season-of-birth bias in association football

In this longitudinal study, we assessed the frequency of birth dates for boys selected for the Football Association National School. Birthdays were divided into three periods of the year: January to April, May to August and September to December. We compared data over a 5 year period and concluded that there is indeed a bias towards selecting older children. Furthermore, analysis of separate data revealed a shift of bias when comparing two different start dates, namely September and January. Our findings show that the youngest children from the January start date (born September to December) are selected significantly more often than the youngest children from the September start date (born May to August). Interestingly, even when the influence of body mass was reduced, the selection bias towards the older players remained.     

Changing Kinesiology and Physical Education by Infusing Information About Individuals With Disabilities

Just as faculty are expected to refer to performance and behavior changes that occur by age, gender, and other factors, an infusion of information about individuals with disabilities requires us to focus on the range of human variability and its relation to physical activity across the life span. This call to infuse information about individuals with disabilities should affect most kinesiology/ physical education undergraduate and graduate curricula in institutions of higher education. Advocacy for this idea has been developing for many years (Hall & Stiehl, 1978; Sherrill, 1988; Stein, 1969). Such infusion could add to and enhance our ability to contribute to the broad goals of society. But for us to assume this role, we must change our curricula to meet our published mission of serving society. This change will help disciplinary and professional preparation programs produce a broader range of scholarly activity and provide leadership that other disciplines may envy     

Children’s Physiological and Emotional Reactions to Witnessing Bullying Predict Bystander Intervention

Study goals were to explore whether children clustered into groups based on reactions to witnessing bullying and to examine whether these reactions predicted bullying intervention. Seventy‐nine children (M = 10.80 years) watched bullying videos in the laboratory while their heart rate (HR) was measured, and they self‐reported on negative emotion after each video. Bullying intervention was assessed by school peers. Two groups emerged based on reactions to the bullying videos: The Emotional group (43% of children) displayed HR acceleration and reported high negative emotion, whereas the Unemotional group (57% of children) showed HR deceleration and reported low negative emotion. Group membership predicted bullying intervention, with peers reporting that Emotional children were more likely to stop a bully than Unemotional children.     

Student drinking in the Third Reich: Academic tradition and the Nazi revolution†

Heavy consumption of alcohol pervaded the student world in Germany to an even greater extent than elsewhere. Many of the fraternities, to which a substantial proportion of the student body belonged, required their members to undergo regular, formal and compulsory drinking bouts. The temperance movement had little effect on students until a general mood of austerity dawned after the First World War. The National Socialists identified themselves with the new sobriety in many policies aside from drink. After Hitler's seizure of power in 1933, one can identify a certain ambivalence in alcohol policies. On the one hand, the puritanical conscience of the Nazis wanted to purge Germany of all decadence, but there was an equally strong impulse for a prolonged victory celebration in traditionally alcoholic terms. This unresolved dilemma can be neatly illustrated through an examination of the universities at the time.

Nazi student leaders indulged in rowdy celebrations after 1933, while denouncing the fraternity world for its alcoholic excesses. This double standard persisted throughout the Third Reich. The Nazis persecuted fraternity members for harmless, drunken horseplay which looked like expressions of political discontent, while plying freshmen with beer and wine themselves, in order to persuade them to join the rather dull, Nazi student organizations. Where alcoholic misdemeanours did occur within the Nazi students’ own ranks, they were treated in various ways, according to political convenience. There was little chance of a strong stand against excessive student drinking with an outright alcoholic as Education Minister during this whole period. In more general terms, the production of beer and wine formed an important part of the German economy, which the government was trying to stimulate, not depress. Drinking remained, then, as a central part of student life despite a promised revolution in all aspects of the academic world. The old traditions persisted, and were sometimes even taken up by the Nazis themselves in their concern for historic roots and legitimacy.

     

Disclosure of information by children in social networking—Not just a case of “you show me yours and I’ll show you mine”

This paper reports the results of a study of MySpace use, by Sydney high school children. It examines the reasons why children disclose information on the website and their understanding of some of the privacy issues involved. The study provides a useful beginning for further work in this area. Regression is used to validate a proposed model of the factors influencing information disclosure and cluster analysis provides an indication of characteristics shared by children who disclose sensitive information, such as name, address and telephone number. It also suggests that children who are taught to value privacy are less likely to disclose sensitive information on-line.
