Hungry rats were used in a classical conditioning procedure in which visual stimuli were paired with food. Conditions in which nonreinforced exposure to a nontarget stimulus was followed by exposure to a simultaneous compound nontarget/target stimulus (a blocking procedure) resulted in enhanced latent inhibition to the target relative to exposure to the nontarget, followed by exposure to the target stimulus alone. A third phase of nonreinforced exposure training, in which the target was exposed alone following the compound, reduced levels of latent inhibition relative to results obtained with the blocking procedure. Experiments also suggested that this was not the result of restoration of associability by the omission of an expected presentation of the nontarget stimulus in the final preexposure phase. These results suggest that enhanced latent inhibition is due to summation of a direct-target-no-event association and a second-order association of these elements via target-nontarget and nontarget-no-event association. Exposure to the target after compound exposure extinguished the target-nontarget association and reduced the sources of no-event learning for the target. 相似文献

从大众高等教育到普及高等教育 总被引:33,自引:0,他引:33
新信息技术的发展要求对普及高等教育的本质进行反思 ,并对其所需条件的认识进行更新 ,这涉及到高等教育制度结构和对待高等教育态度的深刻变革。精英形式的高等教育需进行重新定位。本文在比较的背景下主要分析了美国及欧洲社会的高等教育在走向普及形式的过程中面临危机的原因 ,认为美国特有的结构特征和文化特征赋予了其独特优势。而技术发展的不确定性及各国经济、社会结构的差异性决定了通过新技术扩大入学机会将采取不断实验的方式进行 相似文献

Process performance management provides detailed understanding of the design of a process to improve performance. This article highlights a process performance model aligned with the DMAIC (Define, Measure, Analyze, Improve and Control) steps of the Six Sigma model, but with additional substeps to guide process improvement. It thus identifies process improvement as one of the key tools in the performance technologist's toolkit and provides recommendations for methods, practices, and tools. 相似文献

This study examined whether children’s learning from “Sesame Street” could be improved by having adults ask the children questions
and provide them with feedback while they watched the show. Subjects were 23 three- and four-year-old, white, middle-class
children who were randomly assigned to one of two conditions. Children in both conditions watched three specially edited versions
of “Sesame Street” with an adult. While they did so, children in the experimental condition were asked to name the letters
and numbers shown on the programs. Results indicated that 3 days after watching the last program, children in the experimental
condition were better able to name and identify the letters and numbers they had seen (p < .01). Three features of the experimental
treatment that may have contributed to these results are discussed, as are the implications of the findings. 相似文献

This paper reports a study of the acquisition and use of personal computers by Egyptian science and mathematics teachers. Self-report data was collected from the same teachers on how they had changed their classroom activities and professional practice since their return to Egypt following a twelve-week in-service course in the United Kingdom. The data from this sample of teachers is compared with that from a second sample, who also attended the same in-service programme, but did not report the purchase of a personal computer. Analysis indicates that the Egyptian teachers with personal computers have tended to concentrate on improving the quality of current practice, through better preparation and student testing, rather than introducing major, paradigmatic, changes to their teaching. 相似文献

Abstract Computers and computer software have become integral components of the elementary school curriculum. Classroom teachers often express concern about the inadequate training they receive in the use of technology in the classroom. To meet the needs of future teachers, three university professors added issues related to using technology with young children to existing courses for elementary education majors. In addition, they introduced criteria for evaluating software and gave students opportunities to select software for instruction. After completing the courses, students were more comfortable with using computers, felt more competent about reviewing software, and were more aware of the issues related to using technology for instruction. 相似文献

The Self-Directed IEP has been found effective in increasing student participation in the first Individualized Education Plan (IEP) meeting following Self-Directed IEP instruction. To date, no published reports have examined the extent students are involved during their second IEP meeting following Self-Directed IEP instruction. This study presents an exploratory mixed method case study analysis of a student with a learning disability in sophomore and junior year IEP meetings to illustrate the difference a year can make in IEP meeting participation, the development of postschool goals, confidence, maturity, and self-advocacy. Results indicate a marked increase from year one to year two in the student's word count and speaking rate, a more focused postschool employment vision, and an increase in meeting leadership. Discussion of these results and suggestions for additional research are offered. 相似文献

The creation of quality e-learning material creates a cost dilemma for many institutions, since it has both high variable and high fixed costs. This cost dilemma means that economies of scale are difficult to achieve, which may result in a consequent reduction in the quality of the learning material. Based on the experience of creating a masters level course at the UK Open University, the article suggests that the adoption of learning objects represents one possible resolution to this dilemma. They achieve this through the reduction of the fixed costs by four means: reuse, rapid production, ease of updating and cost-effective pedagogy. 相似文献

AbstractTrends towards the marketisation of the schooling sector have led to suggestions that state-funded schools in England will soon be allowed to operate on a for-profit basis. This article has two aims: to contribute to understanding of the regulation and characterisation of existing for-profit schools in England; and to assess the claim that for-profit schools ‘significantly outperform’ all independent schools by exploring the use of large scale databases including the National Pupil Database (NPD). This study highlights the growth of the for-profit sector, and the scarcity of legislation detailing the financial governance, educational oversight and staffing requirements of schools in the for-profit schooling sector. The for-profit schooling sector is found to be underperforming in terms of school inspection ratings at a level of statistical significance in comparison to the state funded schooling sector. Furthermore, performance indicators relating to GCSE and A level results suggest that the for-profit sector is underperforming compared to the not-for-profit independent sector. As such, the findings of this research have implications in undermining the neoliberal argument that has driven significant change in the schooling landscape in recent times. 相似文献
