Neuropsychological intervention in kindergarten children with subtyped risks of reading retardation     

Smit-Glaudé SW  van Strien JW  Licht R  Bakker DJ 《Annals of dyslexia》2005,55(2):217-245

Kindergarten children at risk of developing language problems were administered the Florida Kindergarten Screening Battery. A principal components analysis revealed a verbal and a visual-spatial component and subsequent discriminant function analyses a high verbal/low visual-spatial group (LAL: Latent L) and a high visual-spatial/low verbal group (LAP: Latent P). LAL- and LAP-children were considered at risk for developing an L- or P-type of dyslexia, respectively. As is common practice with children suffering from manifest L- or P- dyslexia, the LAL- and LAP-kindergartners received right and left hemisphere stimulation, respectively. The outcomes were compared with those of bilateral hemispheric stimulation and no intervention. Reading tests were administered in primary school Grades 1 and 5/6; teachers’ evaluation of reading took place in Grade 5/6. Overall, the LAL- and LAP- groups showed significant backwardness in word and text reading, both at early and late primary school. Types of intervention made a difference though: not significantly backward in early word, late word, and late text reading were the LAL-children who had received right hemisphere stimulation. Nonintervened LAP-children did not show significant backwardness in early word reading and late text reading, nor did LAP-children who had received left hemisphere or bilateral stimulation. Early text reading was not affected by any treatment. Teacher’s evaluations were in support of these findings.  相似文献   

Designing for learning in the Yellow House: a comparison of instructional and learning design origins and practices     

Gale Parchoma  Dirk Morrison  Dorothea Nelson  Kristine Dreaver-Charles 《高等教育研究与发展》2020,39(5):997-1012

ABSTRACT

For the past two decades, there has been persistent debate around whether there is a difference between the fields of instructional design (ID) and learning design (LD). While differences in the two approaches are certainly apparent, there are cross-over points that can provide ID and LD researchers and practitioners with opportunities for dialogue about the purposes and remit of research-based practices for optimal design. Though potentially disruptive, initiating dialogues among learning and instructional designers could lead to more thorough and critical analyses of both ID and LD repertoires. Should boundary crossings occur, there is a potential for a third space for the contemplation, research, and practice of design. A goal of this article is to use the notion of Van Gogh’s Yellow House as an anchoring metaphor for the third space – a location for shared discourse, inspiration, collaboration, and challenge for a community of designers of/for learning. Using the impressionist and expressionist terminology to help elucidate the ways of thinking of designers of both traditions, this article examines the history, underlying philosophical approaches, methodologies, and design goals of ID and LD. We conclude that the emergence of a third space for design can help us move beyond the LD and ID dichotomies. We suggest that a socio-materialist perspective alleviates issues of incommensurability by acknowledging ontological multiplicity.  相似文献   

Trends in gender differences in mathematics and science (TIMSS 1995–2003)     

Oliver Neuschmidt  Juliane Barth  Dirk Hastedt 《Studies in Educational Evaluation》2008,34(2):56

This article investigates changes in gender differences evident in the performance of grade 8th grade students participating in the Trends in International Mathematics and Science Study (TIMSS) between 1995 and 2003. Gender specific results and patterns found in TIMSS 1995 were compared with later cycles of the study in order to address the question of how far the mathematics and science gender gap has narrowed over time. Using a regression approach to compare the trend data, the findings indicated no major changes for mathematics but it appears that the gap in science may be closing, especially in the previously male dominated content areas of chemistry and physics.  相似文献

The Illusion of Linearity: Expanding the evidence towards probabilistic reasoning   总被引：2，自引：0，他引：2  

Wim Van Dooren  Dirk De Bock  Fien Depaepe  Dirk Janssens  Lieven Verschaffel 《Educational Studies in Mathematics》2003,53(2):113-138

Previous research has shown that – due to the extensive attention spent to proportional reasoning in mathematics education – many students have a strong tendency to apply linear or proportional models anywhere, even in situations where they are not applicable. This phenomenon is sometimes referred to as the ‘illusion of linearity’. For example, in geometry it is known that many students believe that if the sides of a figure are doubled, the area is doubled too. In this article, the empirical evidence for this phenomenon is expanded to the domain of probabilistic reasoning. First, we elaborate on the notion of chance and provide some reasons for expecting the over generalization of linear models in the domain of probability too. Afterwards, a number of well-known and less-known probabilistic misconceptions are described and analysed, showing that they have one remarkable characteristic in common: they can be interpreted in terms oft he improper application of linear relations. Finally, we report on an empirical investigation aimed at identifying the ability of 10^th and12^th grade students to compare the probabilities of two binomial chance situations. It appears that before instruction in probability, students have a good capability of comparing two events qualitatively, but at the same time they incorrectly quantify this qualitative insight as if the variables in the problem were linked by a linear relationship. Remarkably, these errors persist after instruction in probability. The potential of this study for improving the teaching and learning of probability, as well as suggestions for further research, are discussed. This revised version was published online in July 2006 with corrections to the Cover Date.  相似文献

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

Joint power generation differentiates young and adult sprinters during the transition from block start into acceleration: a cross-sectional study     

Sofie Debaere  Christophe Delecluse  Dirk Aerenhouts  Friso Hagman  Ilse Jonkers 《Sports biomechanics / International Society of Biomechanics in Sports》2017,16(4):452-462

The aim of this study was to investigate differences in joint power generation between well-trained adult athletes and young sprinters from block clearance to initial contact of second stance. Eleven under 16 (U16) and 18 under 18 (U18) promising sprinters executed an explosive start action. Fourteen well-trained adult sprinters completed the exact same protocol. All athletes were equipped with 74 spherical reflective markers, while an opto-electronic motion analysis system consisting of 12 infrared cameras (250 Hz, MX3, Vicon, Oxford Metrics, UK) and 2 Kistler force plates (1,000 Hz) was used to collect the three-dimensional marker trajectories and ground reaction forces (Nexus, Vicon). Three-dimensional kinematics, kinetics, and power were calculated (Opensim) and time normalised from the first action after gunshot until initial contact of second stance after block clearance. This study showed that adult athletes rely on higher knee power generation during the first stance to induce longer step length and therefore higher velocity. In younger athletes, power generation of hip was more dominant.  相似文献
