Exploring Verbal,Visual and Schematic Learners' Static and Dynamic Mental Images of Scientific Species and Processes in Relation to Their Spatial Ability

The current study compared different learners’ static and dynamic mental images of unseen scientific species and processes in relation to their spatial ability. Learners were classified into verbal, visual and schematic. Dynamic images were classified into: appearing/disappearing, linear-movement, and rotation. Two types of scientific entities and their related processes were investigated: astronomical and microscopic. The sample included 79 female students from Grades 9 and 10. For the purpose of the study, three instruments were used. The Mental Images by Guided Imagery instrument was designed to investigate participants' visualization of static and dynamic mental images. The Water-Level Task was adopted to estimate participants' spatial ability. The Learning Styles Inventory was used to classify participants into verbal, visual and schematic learners. The research findings suggest that schematic learners outperformed verbal and visual learners in their spatial ability. They also outperformed them in their vividness of microscopic images; both micro-static and micro-dynamic images; especially in the case of appearing/disappearing images. The differences were not significant in the case of astronomical images. The results also indicate that appearing/disappearing images received the least vividness scores for all three types of learners.     

Structural dynamic responses analysis applying differential quadrature method

INTRODUCTION The differential quadrature method (DQM) was proposed by Bellman and Casti as an analogous ex- tension of the quadrature method for integrals (Bellman and Casti, 1971; Bellman et al., 1972). It can be essentially expressed as the values of the de- rivatives at each grid point as weighted linear sums approximately of the function values at all grid points within the domain under consideration. As a distinct numerical solution technique to obtain the initial and/or boundary …     

从词义角度谈现在进行时言外之意

英语时态形式与意义不一致的现象是广大英语学习者在英语应用中很容易产生错误的地方。时态的意义和用法并不能以时态形式笼统解释。现在进行时不表示"正在进行"的原因正是动词本身的词义所决定的。根据词义,动词有静态动词和动态动词之分,现在进行时除表示"现在正在进行"的行为动作以外,还包括表示"过去"、"将来"、"渐进"、"重复"、"临时"、"描述"等意义。

Flow shop rescheduling problem under rush orders

INTRODUCTION Rescheduling problem in manufacturing system is considered as a particularly hard combinatorial optimization problem,closely related with uncer-tainty caused by exterior business environment and interior production conditions.Production resched-uling is a common practice in manufacturing compa-nies all over the world.Four sources of production disturbances have been identified:(1)incorrect work;(2)machine breakdowns;(3)rework due to quality problem;and(4)rush orders(Rangsarit…     

A framework of region-based dynamic image fusion

INTRODUCTION Image fusion is a sub-area of more general topics of Information Fusion and Data Fusion and deals with static images and dynamic images (image sequences or video data) (Maitre and Bloch, 1997). By com-bining the information from a range of image data obtained by different sensors or the same sensor with different imaging schemes, the composite image al-ways presents the complementary information of different input images at the same time and provides us the integrated descr…     

“有效性”视域下华语教学若干问题的思考

华语教学是特殊的二语教学,其最终目的是培养华裔青少年具有在现实生活中自由运用华语进行交际的语言能力。但当前,一些认识因素、教学因素和环境因素严重制约着华语教学的“有效性”,只有实现华语教学目标的综合化、教学过程的交际动态化、教学方法的多元化和教学环境营造的多样化,才是促进华语教学的健康发展、提高华语教学“有效性”的必然选择。

基于集对分析的城市生态足迹预测——以武汉市为例

自然生态环境是城市生态系统赖以生存和发展的重要物质基础，生态足迹作为生态环境承载状态测度的指标，受到社会、经济、人口等多种因素的影响，表现出时空动态性和不确定性特征。鉴于集对分析(SPA)在处理不确定性问题的优势，以武汉市为研究对象，将城市总生态足迹与其相关影响因子联系起来考虑，融合集对分析中的同异反模式识别的“择近原则”和聚类分析思想构造集对分析动态模型，模型精度较高，验证误差均小于0.3%。并对武汉市2005年～2020年总生态足迹发展趋势进行了预测。研究结果表明，2005年～2020年总生态足迹将由1 784.662×10⁴hm²增长到2 781.388×10⁴hm²，呈现出低于GDP、高于能源利用率增长速率的趋势，生态环境将进一步恶化，对此就武汉市生态系统的发展提出了对策与建议。最后，指出SPA动态模型对城市生态系统中生态足迹动态化方法的修正具有理论和实际意义。     

论王阳明“意之动”的主体意蕴

王阳明认为,＂意＂指心之发动处;＂意之动＂则是善恶出现的标志,是发动之心分殊之始,也是本心与天理相融亦分的状态。＂意之动＂从＂心之体＂产生而建立在＂心之体＂上,生发＂意之动＂的主体意蕴是无善无恶的;＂意之动＂生于内而发于外,发于外的主体显现出有善有恶的意蕴;而处于内与外之间的主体则呈现主体兼性意蕴。
