Using mobile devices to enhance the interactive learning for spatial geometry

The purpose of this research is to develop a hands-on spatial geometry learning system to facilitate the learning of geometry. The development of this system was based on Duval's four critical elements of geometric learning: perceptual apprehension, sequential apprehension, operative apprehension, and discursive apprehension. The system offers support to high school students in the process of spatial geometry problem-solving. It provides a hands-on approach for manipulating spatial figures, thereby developing the students' visualization skills and ability to conceptualize images. The experiment comprised a total of 58 participants from different classes with the experimental group using the proposed learning system, whereas the control group using the traditional pencil-and-paper approach. The study investigated the effects of the hands-on system on the perceptual, sequential, and operative apprehension, and on overall spatial geometry scores and learning attitude. The results indicated improvements on effective learning and a higher level of sequential, operative apprehension, and overall spatial geometry scores from the experimental group.     

轻笺薄纸间窥一代名伶——浅析《梅兰芳》中“纸”的意象

陈凯歌2008电影《梅兰芳》用诗化气韵讲述了京剧大师梅兰芳的传奇一生。影片中多次出现"纸"的意象(包括信笺、纸枷锁、契约、纸燕等),而这些意象将梅的一生串联起来,点染出其生活中的悲欣哀悦,继而凸显出梅兰芳惊世骇俗的孤清性情。本文将结合符号学的研究方法对电影文本进行解读。

Abstract

The science of cartography went through revolutionary changes in the post-World War II period. In the near future the new types of artifacts and materials produced by the cartographers of this period will form the basis for the study of the history of modern cartography. Computer software, new computational devices, computer hardware, and complex mathematical algorithms all need to be preserved in a way that allows researchers access to the concepts and techniques that make up the cartography of today and the future. The following paper is a case study in the preservation of collections that are typically not part of the traditional materials found in map libraries. Although this paper is pragmatic in nature and focuses in particular on the software and algorithms found in the John Snyder Collection of satellite mapping materials now in the Library of Congress, it also addresses the many conceptual and theoretical problems that arise in the preservation of what the author calls “foundational collections” in the history of cartography.     

The relationship between the use of kinaesthetic imagery and different visual imagery perspectives

In two studies, we examined the strength of relationship between internal and external visual imagery with kinaesthetic imagery. In Study 1, 56 participants completed the Vividness of Movement Imagery Questionnaire and the Movement Imagery Questionnaire. Pearson's product–moment correlations failed to reveal a significant correlation between external visual imagery and kinaesthetic imagery. However, the correlation between internal visual imagery and kinaesthetic imagery approached significance. In Study 2, the instructional set of the Vividness of Movement Imagery Questionnaire was changed to make the participant the ‘agent’ of the external visual perspective images rather than somebody else. Sixty-four participants completed the two questionnaires. The results indicated a significant correlation between external visual imagery and kinaesthetic imagery (r?=?0.60, P?<0.01). However, the correlation between internal visual imagery and kinaesthetic imagery was non-significant (r?=?0.23, P?>0.01). The results are discussed in relation to who is the agent of the image and the processes that may underlie kinaesthetic imagery. The implications for researchers trying to establish the functional, behavioural and neurological differences within, and across, imagery modalities are considered.     

表象训练研究需要注意的几个问题

表象训练是运动心理技能训练中应用最广的一种心理技能训练方法,通过对国内体育运动领域中的表象训练研究报告进行分析,认为存在以下不足：缺乏对变量进行操作性定义、无研究假设、被试选取随意、未进行表象训练效果评估及无关变量控制不严密.表象训练研究必须重视这五个重要问题.

蝴蝶意象与中华民族审美文化心理

“蝴蝶情结”早已成为中国文人中普遍存在的一种文化现象,“蝴蝶情结”作为一种文学意象的心理情结,赏蝶情怀并不是个剐文人的偶然偏好,而是中国文人中普遍存在的一种文化心理现象。蝴蝶作为一个心灵化了的重要符号,展示了丰厚的民族审美文化心理。有关蝴蝶的文化认同在文人心理中是代代传承的,某种程度上又固化了民族审美文化心理。文人以蝴蝶这种文化原型为表现对象,传达的是他们心中长期积淀下来的民族集体无意识。蝴蝶意象并不仅仅在美学的意义上增强文学的含量和艺术张力,而是有着深厚的历史文化内涵。     

基于Landsat影像的环胶州湾不透水面格局演变过程

不透水面是影响城市生态环境的关键因子,及时、精确地掌握不透水面的动态变化对城市的发展规划具有重要指导意义。本文以环胶州湾为例,基于1990年、1995年、2000年、2005年、2011年Landsat TM影像和2016年Landsat OLI影像,采用线性光谱混合分析和决策树相结合的方法分析了环胶州湾不透水面格局演变过程。结果表明：①本文提取的1990—2016年环胶州湾不透水面丰度与验证数据的决定系数R²均在0.70以上,均方根误差RMSE均在16.70%以下。②环胶州湾不透水面面积由1990年的105.17km²增长到2016年的620.02km²,总的扩展方向为由南向北、向东和向西移动。③1990年城阳区成为辅助市区发展的重心,现由城阳区逐渐向黄岛区、崂山区、即墨区和胶州市发展。

基于Fragstats的徐州市景观格局变化分析

选定徐州市中心城区作为研究区域,应用多时相Landsat TM／ETM＋遥感影像为数据源,利用支持向量机（SVM）分类器分别对1994、2000、2005年三个时相的遥感图像进行土地覆盖分类,并在Fragstats3．3景观格局软件平台上,基于景观尺度对徐州市景观格局进行全面的分析,分析结果表明：2005年徐州市景观整体较1994年具有更大的破碎度、更高的多样性和更低的聚集度,景观的类型与格局变化受到人为因素的影响较大;不透水面层逐渐取代耕地和城市绿地。
