This study explored factors predicting the extent to which high school students (N = 140) acquired meaningful understanding of the biological topics of meiosis, the Punnett-square method, and the relationships between these topics. This study (a) examined mental modeling as a technique for measuring students' meaningful understanding of the topics, (b) measured students' predisposed, generalized tendency to learn meaningfully (meaningful learning orientation), (c) determined the extent to which students' meaningful learning orientation predicted meaningful understanding beyond that predicted by aptitude and achievement motivation, (d) experimentally tested two instructional treatments (relationships presented to students, relationships generated by students), (e) explored the relationships of meaningful learning orientation, prior knowledge, instructional treatment, and all interactions of these variables in predicting meaningful understanding. The results of correlations and multiple regressions indicated that meaningful learning orientation contributed to students' attainment of meaningful understanding independent of aptitude and achievement motivation. Meaningful learning orientation and prior knowledge interacted in unique ways for each topic to predict students' attainment of meaningful understanding. Instructional treatment had relatively little relationship to students' acquisition of meaningful understanding, except for learners midrange between meaningful and rote. These findings imply that a meaningful learning approach among students may be important, perhaps as much or more than aptitude and achievement motivation, for their acquisition of interrelated, meaningful understandings of science.  相似文献

PROBLEM: After the Soviet Union dissolved in 1989, it became apparent that there was little recognition of the problems of child abuse and neglect, professionally, legally, or societally. There were no effective systems or laws in place to deal with these problems. METHOD: Beginning in 1995 the Children's Mental Health Alliance, in conjunction with the Open Society Institute began conducting trainings in Eastern Europe [Journal of the American Academy of Child Adolescent Psychiatry 39 (2000) 660]. Originally 18 countries from the Baltics to the Balkans participated. A program was elaborated which would proceed in several stages: (1) training mental health professionals to deal with child abuse and neglect (CAN); (2) teaching multidisciplinary team work and fostering the development of multidisciplinary NGOs focused on CAN; (3) promoting the self-sufficiency of these NGO's which would then facilitate social and legal reform and increase public awareness of the problem. Specific methods included multi-national trainings, assignment of mentors to the developing teams who maintained weekly contact with the teams and made yearly site visits to their countries, and overseeing project grants from OSI. RESULTS: NGO's had been established and registered in 11 countries, many establishing a network of programs within their countries. By 2000, over 3800 mental health professional had been trained, either directly by the program or by the trainees of the program. By the end of 2000, over 17,000 other professionals (lawyers, police, judges, educators, other physicians, etc.) had been trained by the network. CONCLUSION: While more work needs to be in this region, the teams in 11 countries have made solid starts.  相似文献

It is under debate whether the neural representation of numbers and letters might rely on distinct neural correlates, or on a mostly shared neural network. In the present study, a total of 47 children in fifth grade (Experiment 1) and sixth grade (Experiment 2) simply copied numbers and letters on a touch screen while brain activation changes were recorded by means of functional near‐infrared spectroscopy (fNIRS). fNIRS data of both experiments and a joint analysis revealed that a shared neural network, particularly in the left hemisphere, was activated in response to both number and letter copying. Interestingly, no difference was observed in brain activation patterns between these two stimuli, as revealed by Bayesian analysis. Our findings indicate that both number and letter copying lead to similar brain activation in children. We further suggest methodological and applied applications of these findings in the frame of educational neuroscience.  相似文献

The Internet is increasingly being used as a medium for educational software in the form of miniature applications (e.g., applets) to explore concepts in a domain. One such effort in mathematics education, the Educational Software Components of Tomorrow (ESCOT) project, created 42 miniature applications each consisting of a context, a set of questions, and one or more interactive applets to help students explore a mathematical concept. They were designed by experts in interface design, educational technology, and classroom teaching. However, some applications were more successful for fostering student problem-solving than others. This article describes the method used to mine a subset (25) of these applets for design principles that describe successful learner-centered design by drawing on such data as videos of students using the software and summaries of written student work. Twenty-one design principles were identified, falling into the categories of motivation, presentation, and support for problem solving. The main purpose of this article is to operationalize a method for post hoc extraction of design principles from an existing library of educational software, although readers may also find the design principles themselves to be useful. This project was funded by a seed grant from the Center for Innovative Learning Technologies funded by the National Science Foundation (REC # 9720384), and was partially supported by Educational Testing Service. Any opinions expressed in this publication are those of the authors and not necesarily of Educational Testing Service.  相似文献

In this paper we draw from interviews with four lesbian sportswomen and physical educators whose personal journeys inform us about the difficulties and rewards of challenging homophobia and heterosexism. Our co-participants discussed their life stories in terms of the interrelationships among sport, moral, and lesbian identities and their coming out process. Analyses of these narrations revealed three major themes associated with coming out in sport and physical education settings: integrity, compassion, and community. Each of these themes is discussed in terms of our co-participants' experiences and interpretations of moving from fear and isolation to a sense of community and empowerment.  相似文献

The introduction of qualitative modelling techniques into learning environments, and intelligent training systems, requires not just the development of tools and techniques for modelling and simulation but also some guidance on how to use qualitative models in learning environments. This paper describes the rationale behind the design of a simulation based learning environment, the Model Switching PROcess rig Demonstration System (MS‐PRODS). Three qualitative and three quantitative simulations of the behavior of the physical system have been implemented using the ITSIE tools (Scott et al, 1990). The design of the learning environment is presented from the point of view of instruction and how the models are to be used to promote learning, in particular examining the model switching mechanism. This mechanism determines how to select and sequence the presentation of models to the learner during guided explorations of the domain. A knowledge based an alysis of the domain knowledge is combined with principles derived from Cognitive Flexibility Theory (Spiro 6 Jehng, 1990) to produce a generic design for a learning environment based on multiple models. The design and implementation of the learning environment is illustrated and a sample sequence of models presented. Finally, related work such as White & Frederiksen (1990) on model progression is discussed.  相似文献

The importance of quality in the provision of day care services for young children is well established. A project designed to address issues of assessing, maintaining and enhancing standards of service provision in the UK developed a set of self‐assessment materials for use in group day care settings. This paper describes a project to evaluate whether versions of the same materials might be effective in group day care settings in Hungary. Differences and similarities between service provision in the UK and Hungary are described. In a study involving 76 Hungarian day care centres, > 80% of staff involved thought using the materials raised their awareness of quality issues, although the materials did not have a significant impact on the quality of care provided. Key differences between service provision in the UK and Hungary are identified as influencing the potential effectiveness of the materials in assessing, maintaining and enhancing quality.  相似文献

Abstract

Promoting rural development in Africa involves learning to clap with two hands, that is to say, creating effective interaction between local knowledge and development initiatives, on the one hand, and the knowledge and initiatives of formal agricultural research and extension, on the other. Farmer innovators ‐men and women farmers who take their own initiative to change local agriculture ‐ are key allies in rural development, as shown by the experience of the ISWC programme in Africa. Focusing on Ethiopia and Tanzania, the authors describe how formal research and extension services are made aware of farmers’ innovative work and are encouraged to document the results, promote their spread, and support further development efforts by farmer innovators. A modified Participatory Technology Development (PTD) approach is thus emerging, which starts not with problem analysis but rather by linking up with local problem‐solving initiatives. While the learning process on this approach continues, dialogue has been initiated with policy‐makers with a view to incorporating the approach into regular government extension, research and training activities.  相似文献

This study examined the extent to which adultdyslexic readers exhibit concurrent deficitsfor phonological, orthographic and cross-modalword representations, and the relationshipbetween these deficits and decoding ability.Participants were 18 phonological dyslexics and19 normal readers at college level. Compared tonormal readers, dyslexics exhibitedsignificantly slower reaction times acrosstasks, and were less accurate on the unimodalorthographic task. Word pattern processing wasmore extensively related to decoding abilityamong dyslexic as compared to normal readers,but more robustly related to baseline measuresof phonological and orthographic processingamong normal readers. The results are discussedin the context of integrating the phonologicaland orthographic aspects of words, speed ofprocessing deficits, and the importance of taskselection when assessing adult dyslexicpopulations.  相似文献
