During the past decades, many developing countries have been severely hit by a combination of poverty and the HIV pandemic. However, there has been a debate about the relative contribution of these two factors. This study showed that poverty and orphanhood were two separate but interrelated factors contributing to poor schooling. There were no differentials shown based on double orphanhood or gender. We recommend that educational policies should put into consideration both poverty and orphanhood in order to increase schooling access for children affected by HIV/AIDS and poverty. 相似文献

The aim of this study is to analyze the effects of different modes of learning on innovation and profitability in SMEs in two Latin American countries; Mexico and Colombia. The data were obtained using a sample of 250 companies in the industrial sector operating in both countries. Results show that an integrated mode of learning based on internal and external knowledge supported by technological infrastructure have positive and significant effects on the degree of innovation and the profitability in SMEs However this effect appears to be not significantly different from the traditional SMEs mode of learning based mainly on market orientation. 相似文献

Abstract This study was made to determine the influence of five selected motive-incentive conditions upon the effectiveness of a 6-week isometric training program for the development of strength in the elbow flexor muscle group. Data were obtained from an initial test, from each training session, and from a final test. The mean gains in best strength scores from the initial to the final test were statistically significant (p = .05) for all five motive-incentive groups. No significant differences (p = .05) were found between the mean of the scores for the five motive inventive groups obtained during the first training session, during the last training session, from the final test, and from the cumulative scores for the 12 training sessions. 相似文献

Information systems researchers that apply critical social perspectives frequently emphasize the potential for information technology to serve as a mechanism for increased rationalization, domination, and control. Such theorists often overlook or discount the liberating aspects of information systems. In this study, we apply the ideal of rational discourse developed by Jürgen Habermas to the phenomenon of Wikipedia in an effort to explore empirically the emancipatory potential of information systems. We contend that Wikipedia embodies an approximation of the necessary conditions for rational discourse. While several challenges persist, the example of Wikipedia illustrates the positive potential of information systems in supporting the emergence of more emancipatory forms of communication. The corresponding implications for researchers and design professionals alike are discussed. 相似文献

The implementation of peer assessment receives much attention in teacher education. This paper reports the effects of peer assessment training on the performance of student teachers. Ninety-three student teachers were randomly assigned to control groups and experimental groups. The experimental groups were trained in defining performance criteria, giving feedback and writing assessment reports. This was done through peer assessment tasks that were embedded in a redesigned course. Analyses of data derived from peer assessment reports written by the students showed that the experimental groups surpassed the control groups in the quality of the assessment skill. As a result of the training, students from the experimental groups also scored significantly higher grades for the end products of the course than students from the control groups. The results of the questionnaire showed that all students were significantly more satisfied with the redesigned course. 相似文献

There are a growing number of informal science education (ISE) programs in Native communities that engage youth in science education and that are grounded in Native ways of knowing. There is also a growing body of research focusing on the relationship between culture, traditional knowledge, and science education. However, there is little research documenting how these programs are being developed and the ways in which culture and Western science are incorporated into the activities. This study outlines effective practices for using Native ways of knowing to strengthen ISE programs. These effective practices may also be used to promote change in formal education. The authors combine an overview of current research in informal science education with personal interviews with educators engaged in ISE programs offered to youth both on and off tribal reservations as well as experts in Indigenous education. Participating individuals and programs included Native communities across the United States, including Alaska and Hawai??i. Keeping in mind that each community is unique, ISE programs that are grounded in Native ways of knowing will benefit by utilizing the effective practices outlined here as a guide for starting or strengthening existing ISE programs relevant to the needs of their communities. 相似文献

This article provides an extended, comprehensive example of how teachers, schools, districts, and external factors (e.g., parental pressure and policy mandates) shape curriculum research in the U.S. It retrospectively examines how three different middle school curriculum units were implemented and scaled‐up in a large, diverse school system. The curriculum materials were cognitively based, hands‐on, guided inquiry units; each focused on a different “big idea” in science. The units met some criteria for instructional strategies rated by the Project 2061 Curriculum Analysis. Using evidence‐based decisions, two of the units were found to be effective and equitable, and went to scale, but one was not effective. However, the course of scale‐up was also affected by a changing policy climate, and proceeded in unpredictable ways, with small scale effects not found at large scale, and experienced teachers less effective than inexperienced teachers. Four years after funding ended, none of the units were sustained within the school district. The interactions between the demands of the units and of the school district's policy environment suggests reasons why this occurred, despite evidence that two of the units were successful with diverse learners. © 2012 Wiley Periodicals, Inc.

In this study the relationship between domain-specific skills and peer assessment skills as a function of task complexity is investigated. We hypothesised that peer assessment skills were superposed on domain-specific skills and will therefore suffer more when higher cognitive load is induced by increased task complexity. In a mixed factorial design with the between-subjects factor task complexity (simple, n?=?51; complex, n?=?59) and within-subjects factor task type (domain-specific, peer assessment), secondary school students studied four integrated study tasks, requiring them to learn a domain-specific skill (i.e. identifying the six steps of scientific research) and to learn how to assess a fictitious peer performing the same skill. Additionally, the students performed two domain-specific test tasks and two peer assessment test tasks. The interaction effect found on test performance supports our hypothesis. Implications for the teaching and learning of peer assessment skills are discussed. 相似文献

Theory and past research argue for the importance of understanding the effect of various campaign communication forms (e.g., newspapers, television news, radio, debates, candidate advertising, and personal discussions) on levels of issue knowledge (IK). This study used a meta-analytic approach to examine how well these forms predict IK. The aggregate analysis indicates that any of these forms can affect IK but that the different forms are not equally successful. Findings also indicate that the level of campaign interest moderates the effect of reading newspapers and watching television news and that those who watch debates in years with incumbents are less likely to learn. In addition, studies of newspapers are less likely to find significant effects in recent years, even though the issue content of newspapers has increased. The findings also suggest that television news is more likely to influence IK when levels of issue content are greater. These data indicate that measures of media use and IK can systematically influence the study results. Several conclusions are drawn from the research in the hopes of moving toward a theoretical model of communication forms and the attainment of IK. 相似文献
