This paper describes Dragoon, a simple intelligent tutoring system which teaches the construction of models of dynamic systems. Modelling is one of seven practices dictated in two new sets of educational standards in the U.S.A., and Dragoon is one of the first systems for teaching model construction for dynamic systems. Dragoon can be classified as a step-based tutoring system that uses example-tracing, an explicit pedagogical policy and an open learner model. Dragoon can also be used for computer-supported collaborative learning, and provides tools for classroom orchestration. This paper describes the features, user interfaces, and architecture of Dragoon; compares and contrasts Dragoon with other intelligent tutoring systems; and presents a brief overview of formative and summative evaluations of Dragoon in both high school and college classes. Of four summative evaluations, three found that students who used Dragoon learned more about the target system than students who did equivalent work without Dragoon.  相似文献   

Hearing “Quack” and Remembering A Duck: Evidence for Fluency Attribution in Young Children          下载免费PDF全文

Marie Geurten  Marianne Lloyd  Sylvie Willems 《Child development》2017,88(2):514-522

Previous research has suggested that fluency does not influence memory decisions until ages 7–8. In two experiments (n = 96 and n = 64, respectively), children, aged 4, 6, and 8 years (Experiments 1 and 2), and adults (Experiment 2) studied a list of pictures. Participants completed a recognition test during which each study item was preceded by a sound providing either a highly predictive or mildly predictive context in order to make some test items more conceptually fluent. Overall, highly predictive items were recognized at a higher rate than mildly predictive items demonstrating an earlier development of the fluency heuristic than previously observed. The study provides insight into how children develop metacognitive expectations and when they start to use them to guide their memory responses.  相似文献   

MARKETING EDUCATIONAL PROGRAMMES TO COMMERCIAL BROADCASTERS     

D. Lloyd‐Kolkin 《Learning, Media and Technology》1981,7(3):90-92

A major investment in educational television programmes by the federal government led the United States Department of Education to seek ways to extend the audience size for these programmes beyond public television by placing them on commercial broadcast stations in America. This article describes the programmes, the marketing organization and strategies used to promote programming to the commercial marketplace, and the successes achieved in persuading commercial broadcasters to accept educational children's programming, particularly programmes aimed at minority audiences.  相似文献   

Do public schools have a future? A case study of retrenchment and its implications     

Daniel L. Duke  Jon S. Cohen 《The Urban Review》1983,15(2):89-105

The present paper describes a model for predicting the consequences of reduced funding for public education and a case study designed as an initial test of the validity of the model. The case study highlights an inner-city high school in San Jose, California, during the aftermath of Proposition 13. As a result of the passage of Proposition 13 in 1978, severe limitations were placed on the ability of school districts in California to generate revenues from property taxes. San Jose High School was forced to cut programs and personnel. The impact of these cuts on the capacity of the school to serve its urban clients is investigated. Findings from the case study support the model's prediction that budget cuts in public education are more likely to exert a negative impact on disadvantaged students than on students from middle-class homes. Implications of further cuts in public education in general are discussed in the concluding section of the paper.  相似文献

The development of flexibility in equation solving     

Jon R. Star  Colleen Seifert 《Contemporary educational psychology》2006

This paper explores the development of students’ knowledge of mathematical procedures. Students’ tendency to develop rote knowledge of procedures has been widely commented on. An alternative, more flexible endpoint for the development of procedural knowledge is explored here, where students choose to deviate from established solving patterns on particular problems for greater efficiency. Students with no prior knowledge of formal linear equation solving techniques were taught the basic transformations of this domain. After instruction, students engaged in problem-solving sessions in two conditions. Treatment students completed the “alternative ordering task,” where they were asked to re-solve a previously completed problem but using a different ordering of transformations. Those completing alternative ordering tasks demonstrated greater flexibility.  相似文献

Constructing normalcy: a qualitative study of parenting children with Asperger's Disorder     

Jon Lasser  Kristyn Corley 《Educational Psychology in Practice》2008,24(4):335-346

Children with Asperger's Disorder present unique challenges due to their impairments in social functioning. In order to better understand the experiences of parents of children with Asperger's Disorder, interviews were conducted with 20 parents. The interviews were taped, transcribed, and coded using the systematic methods of Grounded Theory. The central phenomenon of “constructing normalcy” emerged from the data as a salient construct for participants. Parents interviewed described a process of meaning‐making with respect to standards of “normalcy” and an effort to create adaptive environments for their children.  相似文献   

Influence of conspecific and predatory Stressors and their associated odors on defensive burying and freezing responses     

Jon L. Williams  David K. Scott 《Learning & behavior》1989,17(4):383-393

In Experiment 1, male rats were exposed to either aggressive (i.e., alpha) or nonaggressive conspecific colonies and tested 24 h later, with or without alpha odors, for freezing behavior and burying of a wall prod that had been the source of a brief electric shock. The results indicated that prior defeat experience and the presence of alpha odors alone during testing had no significant effects, but the combination of prior defeat and alpha-odor testing significantly decreased burying and increased freezing behavior. In Experiment 2, we examined the effects of noncontact exposure to a cat, as a predatory Stressor, during subsequent prod-shock tests involving the presence or absence of cat odors. Exposure to a cat failed to disrupt later prod burying and did not produce freezing. However, the presence of cat odors during testing significantly reduced the amount of defensive burying,without resulting in an increment in freezing. In Experiment 3, rats were given 1, 5, or 30 inescapable preshocks in the presence of either cat odors or a hedonically neutral citronella odor and were tested 24 h later for prod burying and freezing with or without these odors. Both the cat and the citronella odors resulted in a significant reduction in burying and an increase in freezing for rats given 5 and 30 preshocks and tested in the presence of these respective conditioned odors. For the groups that were given 5 preshocks, preshock and later testing in the presence of cat odors resulted in significantly less prod burying and more freezing than for rats that were preshocked and tested in the presence of citronella. The findings of these three ethoexperimental studies are discussed in terms of the learned-helplessness theory, the stress-coping-fear-defense (SCFD) theory, and the concept of selective CS-US associability.  相似文献   

‘Good books’: is there a future for academic writing within the educational publishing industry?     

Jon Nixon 《British Journal of Sociology of Education》2005,26(1):91-103

This paper draws on questionnaire responses received (via e‐mail) during the period 2002–2003 from senior commissioning editors located within seven of the major UK publishing outlets. Drawing on the analytical framework of an earlier study by Nixon (1999 Nixon, J. (1999). Teachers, writers, professionals. Is there anybody out there. British Journal of Sociology of Education, 20(2): 207–221. [Taylor & Francis Online], [Web of Science ®] [Google Scholar]), it focuses on the mediation of educational studies by market forces operating within and upon the educational publishing industry. More specifically it explores issues relating to the construction of readership, authorship and editorship within that force field of market pressures. Central to the argument is the claim that, in its increasing exposure to market forces, the public space afforded by educational publishing is now highly restrictive. The paper concludes with a call for a sustained debate on the future of academic publishing in general, and educational publishing in particular.  相似文献
