Modelling mathematical argumentation: the importance of qualification   总被引：2，自引：0，他引：2  

Matthew Inglis  Juan Pablo Mejia-Ramos  Adrian Simpson 《Educational Studies in Mathematics》2007,66(1):3-21

In recent years several mathematics education researchers have attempted to analyse students’ arguments using a restricted form of Toulmin’s [The Uses of Argument, Cambridge University Press, UK, 1958] argumentation scheme. In this paper we report data from task-based interviews conducted with highly talented postgraduate mathematics students, and argue that a superior categorisation of genuine mathematical argumentation is provided by the use of Toulmin’s full scheme. In particular, we suggest that modal qualifiers play an important and previously unrecognised role in mathematical argumentation, and that one of the goals of instruction should be to develop students’ abilities to appropriately match up warrant-types with modal qualifiers.  相似文献   

Number sense strategies used by 6th‐grade students in Taiwan     

Der‐Ching Yang 《Educational studies》2005,31(3):317-333

In an interview setting, 21 6th‐graders from four public schools in south Taiwan were asked a series of questions, related to whole and decimal numbers, designed to assess their number sense. Eight students were randomly selected from both low and middle performance levels, and five were selected from a high‐performance level, according to their mathematical capabilities. Results indicated that, regardless of performance level, very few number sense strategies (e.g. using benchmarks, estimation or numbers of magnitude) were used. The evidence also revealed that Taiwanese students tended to apply rule‐based methods and standard written algorithms to explain their reasoning. Their inclination to use paper‐and‐pencil procedures narrowed their thinking and reasoning powers: this heavy reliance on written algorithms seemed to be a major impediment to the development of number sense.  相似文献

A novel mutual authentication and key agreement protocol based on NTRU cryptography for wireless communications     

蒋军  何晨 《浙江大学学报(A卷英文版)》2005,6(5):399-404

INTRODUCTION Wireless communications is advancing rapidly in recent years. After 2G (e.g. GSM) widely deployed in the world, 3G mobile communication systems are spreading step by step in many areas. At present, some countries have already launched investigations beyond 3G (B3G) and 4G. Along with the wireless communications’ rapid development, the secure ac-cess authentication of the users within wireless net-works is becoming very critical, and so, more and more attention is focused…  相似文献
