小康社会构建中的农村社区教育应答

小康社会对农村社区教育提出了要求并提供了发展的契机,农村社区教育发展的滞后阻碍了小康社会的构建。农村社区教育因所在区域经济生产方式的不同而表现出不同的特征并存在一些问题,如社区教育定位不清、职业教育功能弱化、学校教育功能缺失、师资队伍短缺以及资金投入不足。农村社区教育的构建可以从外部支持和内部成员自我努力两个方面进行。

关联主义:网络学习环境下劣构问题表征的新取向

问题表征是劣构问题求解的关键步骤.本文剖析了劣构问题表征的过程,从关联主义学习观的视角,对劣构问题表征的实质作出解释,并提出了基于关联主义的劣构问题表征的策略,为网络学习环境下劣构问题的求解提供了一些新的思路和启发.     

改进的ACH方法求解不动点问题

长期以来,人们一直利用同伦方法来计算凸集上的Brouwer不动点问题.对于非凸集上的不动点问题,一直没有相应的结果.直到1996年,于波等人才提出了同伦内点方法来解决该类问题.于波等人进一步把凝聚函数的思想引入到同伦内点方法,从而提出了凝聚约束同伦方法(记作ACH方法).本文对ACH方法进行改进并使得改进的方法能够求解更一般的非凸集上的不动点问题,而且改进的方法还能够扩大初始点的选择范围,并且保留了ACH方法的原有优点,即大大降低了不动点问题的求解规模,从而提高了计算效率.

Moving policy forward: ‘brain drain’ as a wicked problem

The mobility of scientists and the concerns surrounding ‘brain drain’ are not new. Even in the Ptolemic dynasty, the first king set out to attract and influence the movements of scholars to shift the centre of learning from Athens to Alexandria. Yet after all this time, there is still much policy discourse and debate focused on attempting to define, redefine and solve this ancient problem. I argue that the continuing circularity of the debate supports the proposition that the policy issue of brain drain would value from being reconceptualised as a ‘wicked problem’, in order to move policy forward. Drawing upon a historical documentary analysis of the issue from 1990 to 2007 and interviews with current policy‐makers, I propose that reconceptualising this issue will enable actors to collectively and explicitly recognise the fundamental and conflicting perspectives inherent in this social problem that cannot be resolved. This reconceptualisation provides a platform from which policy‐makers can pursue a range of policy responses, attentive to the different perspectives on this issue, rather than spend more time and resources in futilely attempting to achieve a single definitive position and policy response.     

A working memory model applied to mathematical word problem solving

The main objective of this study is (a) to explore the relationship among cognitive style (field dependence/independence), working memory, and mathematics anxiety and (b) to examine their effects on students’ mathematics problem solving. A sample of 161 school girls (13–14 years old) were tested on (1) the Witkin’s cognitive style (Group Embedded Figure Test) and (2) Digit Span Backwards Test, with two mathematics exams. Results obtained indicate that the effect of field dependency, working memory, and mathematics anxiety on students' mathematical word problem solving was significant. Moreover, the correlation among working memory capacity, cognitive style, and students’ mathematics anxiety was significant. Overall, these findings could help to provide some practical implications for adapting problem solving skills and effective teaching/learning.
