关于函数列一致收敛性的一点注记

给出函数列(函数项级数)一致收敛性的一个新的判别法.     

平衡Gold序列的软件实现

在分析m序列、m序列优选对、Gold序列及平衡Gold序列生成原理的基础上,给出了一种平衡Gold序列的软件生成方法.该方法首先用相关验证法产生m序列优选对,然后用循环移位模2加生成Gold序列,最后搜索得到平衡Gold序列,实验结果表明该方法结果正确,便于实现且较为简单.

From natural numbers to numbers and curves in nature —I

The interconnection between number theory, algebra, geometry and calculus is shown through Fibonacci sequence, golden section and logarithmic spiral. In this two-part article, we discuss how simple growth models based on these entities may be used to explain numbers and curves abundantly found in nature     

The interplay of representations and patterns of classroom discourse in science teaching sequences

The purpose of this study is to examines the relationship between the communicative approach of classroom talk and the modes of representations used by science teachers. Based on video data from two physics classrooms in Singapore, a recurring pattern in the relationship was observed as the teaching sequence of a lesson unfolded. It was found that as the mode of representation shifted from enactive (action based) to iconic (image based) to symbolic (language based), there was a concurrent and coordinated shift in the classroom communicative approach from interactive–dialogic to interactive–authoritative to non-interactive–authoritative. Specifically, the shift from enactive to iconic to symbolic representations occurred mainly within the interactive–dialogic approach while the shift towards the interactive–authoritative and non-interactive–authoritative approaches occurred when symbolic modes of representation were used. This concurrent and coordinated shift has implications on how we conceive the use of representations in conjunction with the co-occurring classroom discourse, both theoretically and pedagogically.
