Computer-supported mindfulness: Evaluation of a mobile thought distancing application on naive meditators

The last 2 decades have seen a constantly increasing interest in mindfulness, due to its positive effects on health and well-being. Recently, a number of mobile applications aimed at supporting people in practicing mindfulness techniques have appeared, but their efficacy has not been formally evaluated yet. In this paper, we first introduce the reader to mindfulness techniques, traditional as well as computer-based. Then, we propose and evaluate a mobile application (called AEON) aimed at helping users in practicing thought distancing, i.e. a mindfulness technique that requires one not to react in response to his/her thoughts but to be aware of them and observe them while they go away. AEON allows the user to enter his/her thoughts and visualize them as written in ink on a parchment placed under water. By touching the screen, the user can interact with the water and produce waves that progressively dissolve each written thought. We evaluate AEON on a sample of naive meditators (i.e. people with no or minimal experience with meditation), contrasting it with two traditional thought distancing techniques that are not computer-based. The first traditional technique requires users to mentally visualize their thoughts as printed on clouds and observe them as they pass by, while the second requires users to write their thoughts on cards, then pick up the cards one at a time, look at them and toss them into a wastepaper basket. AEON obtained better results in terms of achieved mindfulness, perceived level of difficulty and degree of pleasantness. Since practicing mindfulness tends to be difficult for naive meditators, these results suggest that AEON can be a novel and effective way to help them approach mindfulness.     

现代汉语常用动词释义对比研究——以《现代汉语词典》(第六版)和《重編國語辭典修訂本》为例

动词在语言中的地位十分重要,而汉语更是一种动词性语言。了解动词的释义,是研究动词的一个重要途径。该文采用《现代汉语词典》(第六版)和《重編國語辭典修訂本》为对比研究的材料,参考新汉语水平考试大纲,选取三者共有的动词词条进行研究,着重对比两本词典对动词的释义,找出普通话和台湾地区所用标准语两者在动词方面的差异,减少两岸交流中因词义不同所产生的误会,更好地促进两岸交流。     

基于自适应定位的传感器频率的对比研究

为了研究传感器的运动频率对目标定位的影响,运用传感器与目标之间的距离信息,提出一种能在连续时间内进行目标定位的线性自适应算法。借助定位算法的稳定性条件,理论分析了传感器的频率对目标定位的作用。进一步通过Matlab仿真,对比研究了不同频率的传感器对固定目标以及持续漂移目标的定位效果。实验表明,传感器的频率会影响目标定位的时间以及定位结果的准确性;高频率的传感器可以减少目标定位所需的时间;在三维空间中,当传感器在每个坐标方向上的振幅相同时,为取得准确的定位结果,传感器的频率分量不能完全相同。对持续漂移的目标进行准确定位,传感器的运动频率要比目标漂移频率高。

A case study of developing ICT-supported pedagogy through a collegial practice transfer process

A collegial practice transfer process between more- and less-experienced teachers was examined in two cases that sought to encourage teachers to use information and communication technology (ICT) in a pedagogically meaningful way. Collegial practice transfer aims to offer new models for in-service teacher training. The process included guiding sessions, training materials presenting authentic pedagogical examples, and try-outs in the classroom. The success of practice transfer was examined through comparing the classroom practices of more- and less-experienced teachers applying the Pedagogical Infrastructure Framework, and through analyzing the tutored teachers' self-reported experiences in interviews. The process provided flexible support and gave self-confidence to the less-experienced teachers. Technology use was successful, but the tutored teachers designed less coherent tasks and weaker support for pupils' collaboration, knowledge construction and metacognition than their more-experienced colleagues. When tutoring, underlying educational ideologies and reasons should be explicated in addition to practical issues of classroom orchestration and technology use.
