Reading guided by automated graphical representations: How model-based text visualizations facilitate learning in reading comprehension tasks     

Pablo Pirnay-Dummer  Dirk Ifenthaler 《Instructional Science》2011,39(6):901-919

Our study integrates automated natural language-oriented assessment and analysis methodologies into feasible reading comprehension tasks. With the newly developed T-MITOCAR toolset, prose text can be automatically converted into an association net which has similarities to a concept map. The “text to graph” feature of the software is based on several parsing heuristics and can be used both to assess the learner’s understanding by generating graphical information from his or her text and to generate conceptual graphs from text which can be used as learning materials. In this study we investigate the effects of association nets made available to learners prior to reading. The results reveal that the automatically created graphs are highly similar to classical expert graphs. However, neither the association nets nor the expert graphs had a significant effect on learning, although the latter have been reported to have an effect in previous studies.  相似文献   

The influence of trait meta-mood on subjective well-being in high school students: a random intercept cross-lagged panel analysis     

Nicolás Sánchez-Álvarez  Natalio Extremera  Pablo Fernández-Berrocal 《教育心理学》2019,39(3):332-352

Trait meta-mood refers to people’s conscious awareness of their own emotions. This reflexive process is relevant to developing a better adaptation to the environment, understanding the individual differences in how people perceive and attend to emotions, and how they can understand and regulate them in an optimal way. Previous research has indicated that trait meta-mood plays an important role in well-being. Accordingly, the main objective of this study was to analyse the prospective effects of trait meta-mood on levels of subjective well-being. A sample of 570 high school students (289 females), from 12 to 17 years (M?=?13.80, SD?=?1.45), completed measures of trait meta-mood, satisfaction with life, and positive and negative mood states across three waves separated by 1-year intervals. Random intercept cross-lagged panel analyses indicated that the dimensions of meta-mood accounted for a significant amount of variance in both cognitive and affective dimensions of well-being across time.  相似文献   

ZigID: Improving visibility in industrial environments by combining WSN and RFID     

Pablo García Ansola  Andrés García  Javier de las Morenas  Javier García Escribano  Francisco Javier Otamendi 《浙江大学学报(A卷英文版)》2011,12(11):849-859

The objective of this work is to provide decision-making processes with an updated/real picture of the mobile resources in industrial environments through a constant feedback of information. The combination of identification technologies and wireless sensor networks (WSN) is proposed as a key development to guarantee an accurate and timely supply of online information regarding the localization and tracking of the mobile wireless devices. This approach uses a cooperative and distributed localization system, called ZigID, which is a WSN based on a Zigbee network with radio frequency identification (RFID) active tags as end nodes. The WSN can recover not only the ID information stored at the tags attached to mobile resources, but also any other useful data captured by specific sensors for acceleration, temperature, humidity and fuel status. This paper also shows the development of ZigID, including devices and information flows, as well as its implementation in ground handling operations at the Ciudad Real Central Airport, Spain.  相似文献

Qué se puede hacer con lo audiovisual en la educación La imagen: un problema trivial con implicaciones básicas     

Pablo del Río 《Cultura y Educación》2013,25(14):5-15

Lo audiovisual está vinculado a dos grandes y graves problemas de la cultura y la educación actuales: la continua renovación en el proceso de estructurar los significados, y las nuevas vías que buscan niños y jóvenes para identificarse y situarse en el mundo, para construir el sentido. Se aboga desde ahí por una renovación profunda de toda la educación y no por la incorporación de un tópico más al diseño curricular.  相似文献

Comparison of starts and turns of national and regional level swimmers by individualized-distance measurements     

Santiago Veiga  Antonio Cala  Pablo G. Frutos  Enrique Navarro 《Sports biomechanics / International Society of Biomechanics in Sports》2014,13(3):285-295

The aim of this study was to compare the race characteristics of the start and turn segments of national and regional level swimmers. In the study, 100 and 200-m events were analysed during the finals session of the Open Comunidad de Madrid (Spain) tournament. The “individualized-distance” method with two-dimensional direct linear transformation algorithm was used to perform race analyses. National level swimmers obtained faster velocities in all race segments and stroke comparisons, although significant inter-level differences in start velocity were only obtained in half (8 out of 16) of the analysed events. Higher level swimmers also travelled for longer start and turn distances but only in the race segments where the gain of speed was high. This was observed in the turn segments, in the backstroke and butterfly strokes and during the 200-m breaststroke event, but not in any of the freestyle events. Time improvements due to the appropriate extension of the underwater subsections appeared to be critical for the end race result and should be carefully evaluated by the “individualized-distance” method.  相似文献   

Assessing the influence of personal preferences on the choice of vocabulary for natural language generation     

Raquel Hervás  Virginia Francisco  Pablo Gervás 《Information processing & management》2013

Referring expression generation is the part of natural language generation that decides how to refer to the entities appearing in an automatically generated text. Lexicalization is the part of this process which involves the choice of appropriate vocabulary or expressions to transform the conceptual content of a referring expression into the corresponding text in natural language. This problem presents an important challenge when we have enough knowledge to allow more than one alternative. In those cases, we need some heuristics to decide which alternatives are more appropriate in a given situation. Whereas most work on natural language generation has focused on a generic way of generating language, in this paper we explore personal preferences as a type of heuristic that has not been properly addressed. We empirically analyze the TUNA corpus, a corpus of referring expression lexicalizations, to investigate the influence of language preferences in how people lexicalize new referring expressions in different situations. We then present two corpus-based approaches to solve the problem of referring expression lexicalization, one that takes preferences into account and one that does not. The results show a decrease of 50% in the similarity error against the reference corpus when personal preferences are used to generate the final referring expression.  相似文献   

An assessment model for proof comprehension in undergraduate mathematics     

Juan Pablo Mejia-Ramos  Evan Fuller  Keith Weber  Kathryn Rhoads  Aron Samkoff 《Educational Studies in Mathematics》2012,79(1):3-18

Although proof comprehension is fundamental in advanced undergraduate mathematics courses, there has been limited research on what it means to understand a mathematical proof at this level and how such understanding can be assessed. In this paper, we address these issues by presenting a multidimensional model for assessing proof comprehension in undergraduate mathematics. Building on Yang and Lin’s (Educational Studies in Mathematics 67:59–76, 2008) model of reading comprehension of proofs in high school geometry, we contend that in undergraduate mathematics a proof is not only understood in terms of the meaning, logical status, and logical chaining of its statements but also in terms of the proof’s high-level ideas, its main components or modules, the methods it employs, and how it relates to specific examples. We illustrate how each of these types of understanding can be assessed in the context of a proof in number theory.  相似文献
