Learning disabled, emotionally disturbed, and unclassified male students (N = 123) originally tested with the Elizur Test of Psycho-Organicity (ETPO) when they were 6 to 11 years of age by Brooks (1) and Jackson (7), were followed-up and reassessed four years later. The test-retest reliability of the total ETPO score was .70, and subtest reliabilities ranged from .47 to .62. The pattern of subtest intercorrelations also remained stable over the four year interval. It was concluded that the ETPO is sufficiently stable for use with school-aged boys, though individual subtest scores should be used with caution.  相似文献

Studies of how scientists select research problems suggest the process involves weighing a number of factors, including funding availability, likelihood of success versus failure, and perceived publishability of likely results, among others. In some fields, a strong personal interest in conducting science to bring about particular social and environmental outcomes plays an important role. Conservation biologists are frequently motivated by a desire that their research will contribute to improved conservation outcomes, which introduces a pair of challenging questions for managers of science and scholars of policies governing science: 1) How do scientists integrate that goal into their processes of research priority evaluation, and 2) How can managers and funders of science utilize that knowledge in designing and administering funding programs? I use Q method to uncover four distinct schools of thought amongst researchers and knowledge-users about the merits of possible research priorities for coral reefs; one of the axes along which these schools of thought differ is in their interpretation of how science can and should interact with policy. The results reveal that perceived severity of reef stressors plays a role for some participants. Disciplinary training does not appear to be a major influence on research priority evaluation, but individual participants indicated professional expediency does prevent some researchers from pursuing or advocating that others pursue topics outside of that disciplinary specialty. Influences on and processes in research prioritization uncovered in this study have the potential to lead to counter-productive disciplinary path dependencies. From these results and building on outside literature, I conclude that better coordination and communication about research priorities across disciplines and with broader stakeholders – including knowledge users – could improve the research enterprise’s ability to contribute to meaningful societal and conservation goals. These findings are relevant to researchers and research administrators across disciplines that seek to conduct or fund science that is useful in addressing specific goals.  相似文献

Transactional distance has been defined as barriers to students’ engagement with learning in the online environment. This research updates Zhang’s (2003) scale of transactional distance, which quantified the extent of the barriers, in light of the massive changes in today’s web-based learning environment. The resulting revised scale of transactional distance (RSTD) is a parsimonious version with 12 elements (compared to 31 original) that measure the transactional distance between student and teacher, student and student, and student and content. The RSTD has excellent factorial validity and reliability, yields better fit statistics, and is easier and less time-consuming to apply. The transactional distance values are unique predictors of student satisfaction, which is correlated to learning and persistence (a major concern with massive open online courses). This information can form the basis for a systematic approach to improving the design of today’s contemporary open, flexible, distance education courses and thus serve as a valuable tool for researchers and educators alike.  相似文献

Abstract

As developing countries gradually rely less upon agriculture for rural income, rural economies require new solutions to access knowledge and information systems for rural development. Non-agricultural rural knowledge and information systems can play a significant role in developing and disseminating successful strategies to escape rural poverty. This paper discusses the challenges of developing rural knowledge and information systems, practical and vital in facilitating rural development in the 21st century.  相似文献

Gauging the effectiveness of specific teaching strategies remains a major topic of interest in science education. Inquiry teaching among others has been supported by extensive research and recommended by the National Science Education Standards. However, most of the empirical evidence in support was collected in research settings rather than in normal school environments. Propensity score analysis was performed within the marginal mean weighting through stratification (MMW-S) approach to examine the effects of the level of openness of inquiry teaching on student science achievement and attitudes with the Programme for International Student Assessment (PISA) 2006 data. Weighting subjects on MMW-S weight successfully balanced all treatment groups on all selected covariates. Significant effects were identified on both cognitive and attitudinal outcomes. For student science achievement, the highest score was achieved at Level 2 inquiry teaching, that is, students conduct activities and draw conclusions from data. For student science attitudes, higher level of inquiry teaching resulted in higher scores. The said conclusions were generally held in most PISA 2006 participating countries when the analysis was performed in each country separately.  相似文献
