The purpose of this study was to examine the role of graphing of self-recorded outcomes and self-evaluative standards on the acquisition of a motoric skill with 70 college students. It was postulated that students who were provided with graduated self-evaluative standards would surpass those who were provided with absolute standards or no standards (control) in both motoric skill and in motivational beliefs (i.e., self-efficacy, attributions, and self-satisfaction). Regarding graphing of self-recorded outcomes, it was hypothesized that students who graphed their results visually would show higher dart skill and stronger motivational beliefs than participants who did not graph their results. Support was found for these hypotheses. The implications of findings of this study were discussed for instructors in terms of how the effects of self-directed practice can be enhanced.  相似文献

This study investigated the chemistry laboratory classroom environment, teacher–student interactions and student attitudes towards chemistry among 497 gifted and non-gifted secondary-school students in Singapore. The data were collected using the 35-item Chemistry Laboratory Environment Inventory (CLEI), the 48-item Questionnaire on Teacher Interaction (QTI) and the 30-item Questionnaire on Chemistry-Related Attitudes (QOCRA). Results supported the validity and reliability of the CLEI and QTI for this sample. Stream (gifted versus non-gifted) and gender differences were found in actual and preferred chemistry laboratory classroom environments and teacher–student interactions. Some statistically significant associations of modest magnitude were found between students' attitudes towards chemistry and both the laboratory classroom environment and the interpersonal behaviour of chemistry teachers. Suggestions for improving chemistry laboratory classroom environments and the teacher–student interactions for gifted students are provided.  相似文献

The teaching of sick children in hospital is an often overlooked aspect of Ireland’s national education system. Prior to the 1970s, there was hardly any formal structure in place for this type of schooling in the country, despite the fact that many children could be inpatients for weeks or months at a time. In 1980, a report, published by the Association for the Welfare of Children in Ireland, revealed that although there had been an improvement in the intervening decade, only 6% of hospitals had a dedicated schoolroom. Drawing on previously unresearched papers belonging to Temple Street Children’s Hospital, this article will take a closer look at the socio-political forces that held back the development of the hospital classroom in Ireland for so many decades; it will also explore some of the factors that promoted its development after 1970, thus helping to explain why the education of sick children is so firmly established today.  相似文献

In order to understand the task of instructional designers who produce learning support software, this paper reviews the influence of learning theory on instructional design, recent developments in computer technology, and the evolving role of the instructor as a facilitator of higher-order thinking. Constructivist principles of learning and an appreciation for the fact that the learner must become more independent and skilled in metacognitive self-assessment and self-management are fundamental to this changing role. Two cognitive tools that provide learner/user support for personal construction of knowledge systems are “MindMap” and “Learning FourMat Processor.” These tools are examined in the light of current learning theory and a recent study comparing the work of novice and expert writers using different forms of performance support. Recommendations are made for the development of a more complete set of cognitive tools that enables users to construct their own multimedia knowledge systems based on higher-order thinking and problem solving.  相似文献

The usefulness of a baseline record is often compromised by extraneous events in the natural environment that artificially intervene to prevent the performance of a specific target behavior. To attenuate this problem, a simple ratio adjustment procedure was suggested that compares the observed response frequency with a maximum possible frequency for each observation period. This ratio is then transformed into a response percentage with a more general predictive value for the behavior modification practitioner.  相似文献

The aim of this study was to build an accurate computer-based model to study the water flow and drag force characteristics around and acting upon the human body while in a submerged streamlined position. Comparisons of total drag force were performed between an actual swimmer, a virtual computational fluid dynamics (CFD) model of the swimmer, and an actual mannequin based on the virtual model. Drag forces were determined for velocities between 1.5 m/s and 2.25 m/s (representative of the velocities demonstrated in elite competition). The drag forces calculated from the virtual model using CFD were found to be within 4% of the experimentally determined values for the mannequin. The mannequin drag was found to be 18% less than the drag of the swimmer at each velocity examined. This study has determined the accuracy of using CFD for the analysis of the hydrodynamics of swimming and has allowed for the improved understanding of the relative contributions of various forms of drag to the total drag force experienced by submerged swimmers.  相似文献
