Inter-Parietal White Matter Development Predicts Numerical Performance in Young Children     

Cantlon JF  Davis SW  Libertus ME  Kahane J  Brannon EM  Pelphrey KA 《Learning and individual differences》2011,21(6):672-680

In an effort to understand the role of interhemispheric transfer in numerical development, we investigated the relationship between children's developing knowledge of numbers and the integrity of their white matter connections between the cerebral hemispheres (the corpus callosum). We used diffusion tensor imaging (DTI) tractography analyses to test the link between the development of the corpus callosum and performance on symbolic and non-symbolic numerical judgment tasks. We were especially interested in the interhemispheric connections of parietal cortex in 6-year-old children, because regions of parietal cortex have been implicated in the development of numerical skills by several prior studies. Our results revealed significant structural differences between children and adults in the fibers of the corpus callosum connecting the left and right parietal lobes. Importantly, these structural differences were predictive of individual differences among children in performance on numerical judgment tasks: children with poor numerical performance relative to their peers exhibited reduced white matter coherence in the fibers passing through the isthmus of the corpus callosum, which connects the parietal hemispheres.  相似文献   

Comparing active delay and procrastination from a self-regulated learning perspective     

Danya M. Corkin  Shirley L. Yu  Suzanne F. Lindt 《Learning and individual differences》2011,21(5):602-606

Researchers have proposed that the act of postponing academic work may be divided into a traditional definition of procrastination, viewed as maladaptive, and adaptive forms of delay. Adaptive forms of delay may be more consistent with certain facets of self-regulated learning. The current study investigated this issue by examining whether the relations between aspects of self-regulated learning and active delay may be distinct from the relations these aspects of self-regulated learning have with procrastination. Among 206 undergraduates, procrastination was positively predicted by mastery-avoidance goals and negatively by metacognitive strategy usage, whereas active delay was negatively predicted by avoidance goals and positively by self-efficacy. Furthermore, students who reported higher levels of active delay also received better grades. These findings provide support that active delay is a distinct form of delay from procrastination that may be more positive due to its associations with some adaptive self-regulatory processes and academic achievement.  相似文献   

Reclaiming Kindergarten: Part II: Questions About Policy     

Dominic F. Gullo  Kim Hughes 《Early Childhood Education Journal》2011,38(6):393-397

Part II of “Reclaiming Kindergarten” continues the discussion related to responding to the crisis in today’s kindergarten. In Part II, two policy questions are posed, the answers to which seek to respond to this continuing crisis. The questions center on issues related to engaging families in kindergarten and the need to consider a new early childhood paradigm where kindergarten is part of a continuous and seamless educational experience spanning prekindergarten through third grade. As in Part I, examples of classroom practice are used to illustrate the effective implementation of these principles in a kindergarten classroom.  相似文献   

Classroom action research on formative assessment in a context-based chemistry course     

Johannes Vogelzang  Wilfried F. Admiraal 《Educational Action Research》2017,25(1):155-166

Context-based science courses stimulate students to reconstruct the information presented by connecting to their prior knowledge and experiences. However, students need support. Formative assessments inform both teacher and students about students’ knowledge deficiencies and misconceptions and how students can be supported. Research on formative assessments suggests a positive impact on students’ science achievement, although its success depends on how the formative assessment is implemented in class. The aim of this study was to provide insights into the effects of formative assessments on achievement during a context-based chemistry course on lactic acid. In a classroom action research setting, a pre-test/post-test control group design with switching replications was applied. Student achievement was measured in two pre-tests, two post-tests and a retention test. Participants were Grade 9 students from one secondary school in the Netherlands. Repeated-measures analysis showed a significant effect of formative assessments on students’ achievement. During the implementation of the formative assessments, intriguing discussions emerged between students, between students and teacher, and between teachers. Adding formative assessments to context-based approaches reinforces their strength to meet with the current challenges of chemistry education. Formative assessments affect students’ achievement positively and stimulate feedback between students and teacher(s).  相似文献   

Monitoring the Use of a Staff Student Liaison Committee for Feedback in Quality Engineering Education     

F. Bullen  R. Black 《European Journal of Engineering Education》1995,20(4):473-480

The paper explores the use of a staff student liaison committee (SSLC) as one of the mechanisms for assuring quality in civil engineering education. The School of Civil Engineering at the Queensland University of Technology, Australia, is used as a case study. The school has a SSLC which meets about six times per year and has representatives of all undergraduate courses and some academic staff. It was thought that the SSLC was well regarded by staff and students and contributed to the learning experience of students within the school. A questionnaire was used to ascertain the views of staff and students regarding the effectiveness of the committee in promoting good quality education. The findings indicated that the SSLC was playing an important role, but that it was not as well regarded as academic staff thought, and that many students were not fully aware of its activities. The school has used the findings to adopt new methods of distributing information to the student body and for ascertaining student opinion, principally electronically.  相似文献

Concept learning by pigeons: Matching-to-sample with trial-unique video picture stimuli     

Anthony A. Wright  Robert G. Cook  Jacquelyne J. Rivera  Stephen F. Sands  Juan D. Delius 《Learning & behavior》1988,16(4):436-444

Pigeons were trained to match-to-sample with several new methodologies: a large number of stimuli, computer-drawn color picture stimuli, responses monitored by a computer touch screen, stimuli presented horizontally from the floor, and grain reinforcement delivered onto the picture stimuli. Following acquisition, matching-to-sample concept learning was assessed by transfer to novel stimuli on the first exposure to pairs of novel stimuli. One group (trial-unique), trained with 152 different pictures presented once daily, showed excellent transfer (80% correct). Transfer and baseline performances were equivalent, indicating that the matching-to-sample concept had been learned. A second group (2-stimulus), trained with only two different pictures, showed no evidence of transfer. These results are discussed in terms of the effect of numbers of exemplars on previous failures to find concept learning in pigeons, and the implications of the positive finding from this experiment on abstract concept learning and evolutionary cognitive development.  相似文献

Developmental issues in cognitive mapping: the selection and utilization of environmental landmarks   总被引：1，自引：0，他引：1  

G L Allen  K C Kirasic  A W Siegel  J F Herman 《Child development》1979,50(4):1062-1070

2 studies were conducted to investigate developmental differences in the ability to select and use environmental landmarks for cognitively organizing distance information from a walk. In experiment 1, second-grade, fifth-grade, and college subjects viewed a simulated walk and selected scenes that were high in potential landmark value. In experiment 2, children from the same grade levels first viewed the walk and then ranked distances among either the test scenes most frequently selected by their peers or those selected most frequently by adults. Results indicated that (a) adults and children may not spontaneously select the same features as real-world landmarks; (b) children are less capable than adults in judging the value of potential landmarks as distance cues; and (c) the ability to use environmental landmarks as cues for distance information developmentally precedes the ability to assess this potential information value.  相似文献
