地矿勘查信息化与地矿信息科技学科建设     

吴冲龙  刘刚  田宜平  张夏林  李伟忠 《中国地质教育》2005,14(1):32-35

“地矿勘查信息化”是指采用信息系统对传统的地矿勘查工作主流程进行充分改造, 实现全程计算机辅助化, 数据在各道工序间流转顺畅、充分共享。“地矿信息科技”学科的形成和发展, 既是地矿勘查的信息化和地质学定量化发展的需要, 也是地球信息科学和地理信息科学学科形成发展的推动。为满足地矿勘查的信息化和地质学定量化进程, 适应地球信息科学发展的形势, 应当在重视并加强地矿勘查工作信息化的理论研究和技术开发的同时, 不失时机地创办“地矿信息科技”本科专业, 并加紧进行这一学科体系建设、专业建设和人才培养。  相似文献   

Complexity in Science Learning: Measuring the Underlying Dynamics of Persistent Mistakes     

Ethan Fleuchaus  Adam W. Kiefer  Paula L. Silva 《Journal of Experimental Education》2020,88(3):448-469

Abstract

Mistaken beliefs pose a barrier to science learning. For this reason, it is important to understand the circumstances in which they emerge and change. In the current paper, we apply complexity theory to shed light on the nature of mistaken beliefs. The strength of this approach lies in conceptualizing beliefs as dynamic stabilities, a well-defined construct that can be indexed precisely. For example, Recurrence Quantification Analysis (RQA) can determine the presence of dynamic stabilities by analyzing variability in time-series data. We applied this analytical tool to probe for mistaken beliefs in a beam-balancing task, a task that is known to elicit mistaken beliefs in preschoolers. Using a case-study design with four preschoolers, we tracked children’s hand position with motion sensors as they balanced various beams. The resulting time series of hand position was submitted to RQA, yielding two important results: First, we found that consistent mistakes in trying to balance the beams were not always accompanied by dynamic stability. This undermines the common assumption that overt consistency in task performance is sufficient to conclude the presence of beliefs. Second, we found strong individual differences over time, as children explored the balance beams. Applications to science education are discussed.

• Highlights

• A classical task of beam balancing was used to explore the underlying dynamics of children’s mistaken beliefs.

• Moment-to-moment hand movements were tracked and subjected to a multi-dimensional recurrence quantification analysis (RQA).

• Dynamic stability was captured through percent laminarity (%LAM), a measure of rigidity in children’s explorations.

• The RQA measure of %LAM shed light on patterns of stability that were not available from the analysis of overt behavior.

• In line with complexity theory, a model of persistent mistakes is offered that has important implications for science education.

Quantifying the immeasurable: A reflection on sport,time and media     

Hibai Lopez-Gonzalez 《体育哲学杂志》2013,40(3):347-362

In the last century, professional sport has experienced a process of standardization that has favoured the development of its two most recent characteristics: the quantification and the pursuit of records, as Guttmann exposed in From Ritual to Record (1978). This article reflects on the ramifications that those characteristics have had in the sport consumption of sport in recent times, focusing particularly on the temporal consequences. The work proposes an ‘evolutive time’ perspective to understand the double fundaments of the sporting temporality: its cyclical dimension of recurrences and familiar elements; and its linear dimension of newness and uniqueness. The argument is that sport draws on elements derived from quantification and records such as time serialization and time disruptions in order to produce a globally appealing and intelligible commodity.  相似文献

Old and Grumpy but Still Game     

Wray Vamplew 《国际体育史杂志》2017,34(5-6):456-460

Abstract

My background as an economic historian has strongly influenced my approach to sports history which I practise as a combination of theory and empiricism, particularly of the quantitative kind. Theory is central to our understanding of the social science of sport and evidence makes the subject history rather than fiction. As sports historians we should emphasize that our discipline is as ‘mainstream’ as any other form of history and we can contribute to major historical debates on, for example, race, gender, identity, and nationalism.  相似文献   

关于语言学研究中量化问题的几点思考     

张彤 《伊犁师范学院学报》2006,(1):95-97

我国语言学研究在与世界接轨的过程中要解决量化不够的问题,在追求量化的过程中也暴露出一些问题。对这些问题的反思可以澄清对量化的一些认识:1.我国语言学研究队伍的知识结构不够完善,量化的传统需要长期培养。2.量化方法对操作者的操作技能和科学态度有较高的要求,重视不够会造成量化的失实。3.应科学地利用数据资源,对语言学研究中的量化问题应该做系统地规划,集中人力和财力科学合理地采集数据,提高量化的效率和质量。  相似文献
