We use eye tracking as a method to examine how different mathematical representations of the same mathematical object are attended to by students. The results of this study show that there is a meaningful difference in the eye movements between formulas and graphs. This difference can be understood in terms of the cultural and social shaping of human perception, as well as in terms of differences between the symbolic and graphical registers. 相似文献

AbstractThe early 1910s marked a turning point in Canadian immigration policy history. With the introduction of the Immigration Act of 1911, the Canadian state effectively declared black people, Asians, and most other people of colour to be unfit and unsuitable immigrants. Nation-building efforts encouraged a white Canada; as such, the Canadian Amateur Athletic administration approached the 1912 Games as an opportunity to attract ‘suitable’ white European immigrants. Amidst sustained anti-black immigrant discourse in policies and the press, Canada’s 1912 Olympic team included, for the first time, a black athlete: John Armstrong ‘Army’ Howard, an emerging sprinting talent from Winnipeg (Manitoba) who had done well in national meets. Howard’s racial identity was not only the antithesis of a white Canada, he was also a recent American immigrant. Yet, his potential made him one of most prominent medal hopefuls for a nation looking to secure its position on the world stage. In this way, Howard’s tenure on the national team underscores the fragile and conditional space which ideas of race and nation have largely occupied in Canada, and the role of sport and the Olympics in shaping them. 相似文献

In a population of 1141 students attending the last year of secondary school (age 17‐19) in three towns of North, Central and South Italy, who were tested using four ability tests, we studied responses to six moral dilemmas, comparing subjects of low, average and high ability by means of analysis of variance and cluster analysis. Two groups of very high (5 percent of the total sample) and extremely high (2 percent) students were individually interviewed in order to explore the motivation for their choices. The gifted showed, as expected, more responses at the formal level (greater choice of items concerning general and abstract principles, greater support for law and social contracts, more coherence), but in the average and lowest groups we found a more sentimental, humanitarian orientation, with a sympathetic attitude towards other people's feelings, which can constitute the base for a more intuitive, but not inferior morality. 相似文献
